My Air Conditioner Froze Up


It’s a bizarre sight, but not uncommon. On a sweltering Corpus Christi Day when the sun is shining, you find that your outside air conditioner is covered in ICE! 

What should you do when you have a frozen air conditioner? 

Calling Tiger Heating & Air is to come out and fix your AC will get you back up and running, but there are a few DIY steps you can try yourself. There may be a relatively simple problem causing your air conditioner to freeze up, and one you might be able to repair quickly and cheaply! 

We will go over the most likely reasons why ice develops on an air conditioner. Some have troubleshooting steps that many homeowners can try to tackle on their own. Other causes are best left to trained HVAC repair technicians who can accurately diagnose the problem and successfully resolve it. 


No matter what is causing your AC to freeze up, there is an basic – yet critical – step you must do first. You need to get your AC unit thawed. And that starts at your thermostat. 

It is turning the thermostat to OFF. And then turn the fan ON. This will start the defrosting process.

If it’s a hot day, your AC could be fully thawed in just a couple of hours.  

If the conditioned air is cool and the unit doesn’t freeze up again, you are good to go. If it does freeze up again, turn the air conditioner back OFF and the fan set to ON. Then you will need to call an experienced AC repair technician, like our fabulous HVAC team at Tiger, as you’ve got a bigger problem on your hand.  


1. Dirty Air Filter 

Very dirty air filter that caused an AC unit to freeze up with ice

The most likely cause of a frozen air conditioner coil is not enough air flowing over the evaporator coils. The air that flows over your coils loses its heat to the coils, but if not enough air is flowing, the refrigerant gets too cold and might cause the coils to freeze.  

The leading reading why the airflow could be hampered is that your air filter is dirty. A dirty filter can block or clog airflow and is a common cause for an air conditioning unit to freeze up. 

While the AC unit is thawing out, check the air filter on your furnace. If it’s dark and dirty, replace it even if it’s not on schedule to be replaced yet. Many homeowners do not change their filters as frequently as they should.  

Once your air filter is replaced and the AC unit is thawed out, you should try to turn the AC back on at the thermostat and see if it works now. 

2. Blocked (or closed) return ducts 

There is a common misconception that you should close any vents that you don’t need to save on energy use and cost. That is not the case. The ductwork in your home, including the vents, was designed to work as a system. Closing off too much of this system can cause it not to work correctly. It may be okay to have a few vents closed, but this can cause problems, including a frozen AC unit if you have too many. 

Are any vents in your home closed or obstructed? Check the vents in your home to make sure they are open and not blocked. Move aside any items, including furniture or curtains, covering or blocking the vents.  

3. Low Refrigerant Levels 

Being low on refrigerant (freon) is the main reason why air conditioners freeze up. Often that indicates there is a leak in your system. This is a potentially dangerous problem and should be resolved only by a trained AC technician. 

Call Tiger Heating & Air for 24/7 emergency repair in Corpus Christi, TX

4. Dirty evaporator coils 

Dirty evaporator coils are another problem that can cause an air conditioner to freeze.  

If there is any buildup on these coils, they won’t be able to absorb the heat it needs to produce cool air for your home. If the filter is clean, and you still have poor airflow, it is likely being caused by a dirty coil. 

Performing annual maintenance on your system should keep this problem from happening. Tiger Heating & Air provides professional AC maintenance and tune-up service. Call us at 361-852-4450 to get a technician scheduled. 

5. Mechanical Failures 

Various mechanical problems can cause an outdoor unit to freeze. An HVAC system involves a lot of components. Perhaps there is a kink in a refrigerant line, or the blower fan is not working. These sorts of mechanical failures can cause the pressure to change in your system and make your air conditioner freeze up. 

Another problem that can cause ice to form on your air conditioner is a broken or malfunctioning blower motor. This part inside your AC makes sure that the fan blows return air over the evaporator coils. If not enough air moves over the coils, your air conditioner will get too cold and freeze up. 

6. Temperature is Cold Outside 

Did you leave your thermostat on COOL during a cold snap? If you are running your AC when the outside temperature dips into the 50s or below, the pressure inside of your system will drop. That is enough to cause a freeze-up of your air conditioner.

If one of the above problems was something you can tackle and fixed your frozen AC, that’s great! However, you are not out of the woods yet. You want to make sure that your air conditioning system doesn’t refreeze. Give it time, and make sure your system remains ice-free. If it freezes up again, that means that whatever troubleshooting step you did was not enough to fix the problem completely. You will need to call for a professional AC repair.  

Tiger Heating & Air is trained and experienced to service any type or model of air conditioner or cooling system. We provide 24/7 service to the entire Corpus Christi area and can be trusted to provide you with friendly, quality service at a fair price. Call on us to fix any AC problem! You can read reviews from people across Corpus Christi on why they say you can’t go wrong with Tiger!

How to Stay Cool During a Heat Wave

Important Tips to Be Safe & Comfortable in a Hot Corpus Christi Summer

heat wave

We know how a Corpus Christi summer can be a scorcher, and it’s difficult to keep cool throughout the hottest months. Here are some ways to stay cool during these hot days from the Corpus Christi cooling experts at Tiger Heating & Air.

This post is for homeowners who are looking for ways to stay cool during a heatwave. We’ll cover topics like how to keep your house cooler, what clothes you should wear and even suggestions on what to eat. 

8 Steps to Stay Cool

  1. Drink water: Dehydration can make you feel worse in the heat. So drink lots of water!
  2. Wear light clothing: Light colors will reflect heat away from your body and dark colors absorb it instead. Keep the fabrics thin or loose for maximum breathability as well.
  3. Stay out of direct sunlight, especially during the peak hours between 10am to 4pm. If you must be outside, wear a hat, sunglasses, and sunscreen to protect yourself from the sun’s rays.
  4. Set your thermostat temperature to between 74 – 78 degrees when you’re home and awake. Then set it to be just up a couple degrees when you’re sleeping. Program the temperature to raise to about 86 during the hours no one is home.
  5. Keep your home as cool as possible with window shades and fans to circulate air. While it might seem like an energy-saving tool to shut vents to rooms not in great use, be careful not to shut too many. Your home’s entire cooling system was designed to work with the vents open and shutting too many could disrupt the airflow and even damage your home’s air conditioning units.
  6. Eat cold foods and drink cold drinks (especially water – see tip #1). Cold food and beverages can help cool down your body.
  7. Avoid caffeine and alcohol which can dehydrate you.
  8. Take a cool shower or bath. It’s become trendy to take cold showers, as people claim it helps your mental and physical health. A hot Texas summer may be the perfect time to try out cold showers yourself!

We hope this article has been helpful in providing you with some tips and tricks to stay cool during a heatwave. If your AC breaks down, don’t panic! You can call Tiger Heating & Air for emergency AC repair service 24 hours a day, 7 days a week.

What is the AC SEER Rating?

Understanding SEER & Texas requirements for air conditioners

Tiger Heating & Air AC technicians studying SEER rating at Corpus Christi shop

Let’s discuss one of the most misunderstood terms about air conditioning – the SEER rating. SEER is one of the most essential factors in determining what AC to purchase, but it is a confusing matter for many homeowners.

At Tiger Heating & Air, we know a well-informed customer is a happy customer with a home that keeps them comfortable for many years to come. So we want to provide you with the most basic (yet important) pieces of information to understand the SEER rating. You will learn why it’s important to understand before making any change to your home’s cooling system.

Why do I need to understand the SEER rating?

The bottom line is that understanding what the SEER rating is can end up saving you money. A home cooling system is a significant investment for your home. You’re will spend thousands of dollars on getting it installed. And then you will continue to spend thousands more on your energy bills. But how much you spend each month depends a lot on the SEER rating of your AC unit. An air-conditioner with a good SEER rating can save you hundreds of dollars on your energy costs each year!

What is the SEER Rating?

SEER stands for Seasonal Energy Efficiency Ratio. It is a measurement of the amount of energy your AC will need to consume in order to operate. SEER is a ratio of how much cool air your system puts out for each unit of energy it consumes. It’s a complex math formula, but it’s all about “tons.” A ton of cooling equals about the energy needed to melt 1 ton of ice over a 24-hour period.

Do I Want a High or Low SEER Rating?

Generally speaking, an AC with a higher SEER rating is better. The higher the SEER rating, the more efficient that air conditioner will be. But that doesn’t mean you should simply get the air conditioner with the highest SEER rating there is. You always need to make sure you are getting the perfect system for your home. How high of a SEER rating you should look for depends on a few factors, such as the size of your house and where you live.

Ready to throw your old AC to the curb? Call Tiger Heating & Air for new cooling installation

What SEER rating is Needed for Corpus Christi Homes?

The U.S. Department of Energy requires all new AC units to meet certain levels of energy efficiency. These levels are determined by the SEER rating.

In 1992, the government enacted the first-ever SEER efficiency standards. Back then, it was common for homeowners to have an AC with a SEER of just 8 or 9. The first SEER rating required all new AC units installed in homes to be at least SEER 10. Despite Texas and other southern states having greater cooling demands than the rest of the country, this SEER 10 minimum rating was for all states.

In 2006, the DOE increased the minimum standard to 13. But regulation changes were on the way, and different climate regions were treated separately.

In 2015, government regulators raised the SEER minimum to 14 for split system central air conditioners for Texas and other states in the country’s Southeastern region. And another SEER change is on its way. Starting in 2023, only ACs with a 15 SEER or higher can be installed.

Back when the first regulations started, some homes had AC units that were as low as 6 SEER. Today, it is not uncommon to see many in the 20s. Tiger Heating & Air are Corpus Christi’s certified Trane Comfort Specialists. We can install a new, efficient Trane air conditioner in your home that range from 14.5 SEER up to 22.

Are you looking for help on determining what new cooling system is right for you? Give Tiger a call at (361) 852-4450, or you can check out Trane’s HVAC Tips & Buying Guide.

How Much Money Can a High SEER Rating Save Me?

Unfortunately, there isn’t an absolute answer. There are various factors that determine a home’s ongoing energy costs, such as the size and amount of insulation. However, increasing your home’s SEER rating by 10 can result in your air conditioner using half as much energy. How much will a higher SEER system save you? See what your current system’s rating is, and you can find out how much money you will save in energy costs with this online calculator.

How To Use the SEER Rating To Shop for a New AC

Knowing how SEER factors into how much energy you use each money makes you better able to compare different air conditioning systems. The SEER rating tells you which units will expend the least amount of energy and save you money on your utility bills.

As we’ve mentioned, SEER isn’t the only factor to consider when purchasing a new air conditioner. Our experienced Tiger Heating & Air AC technicians can help assess your home’s specific needs to help you determine which cooling system and unit is suitable for your home.

With several decades of experience installing air conditioning units in homes across Corpus Christi, you can trust Tiger Heating & Air to find the best home cooling options for you. Call us today at (361) 852-4450.

AC Not Turning On? A Homeowner’s Checklist

6 Steps to Repair an Air Conditioner that Won’t Turn On

6 Steps to Repair an Air Conditioner that Won’t Turn On

Have you been waiting for the cool air to come but your air conditioner is not turning on? Your first reaction may be to call us or another Corpus Christi AC company to come get your broken air conditioner fixed right away. While you can definitely call us to get a technician out for a quick repair, you may want to take a moment to check a few things out for yourself.

Should You Call a Professional if your AC Doesn’t Turn On?

Photo of air conditioner unit in Corpus Christi

Not necessarily. There are several possible problems that could cause an air conditioner to not turn on. And while a trained HVAC technician should be able to handle whatever the problem may be, some AC issues are easy to spot and handle on your own!

While a lot of causes to a broken AC do require one of our skilled technicians to identify and fully fix, sometimes our technicians are called out for problems that end up being simple and easy enough for the homeowners to handle on their own.

While we are happy to come out and address whatever cooling problem you are having, we want you to be armed with the information about some of the simpler problems that don’t always require professional repair. If it’s something you can fix, handling a simple air conditioning repair on your own will save you time and money.

When you find your air conditioner won’t turn on, refer to this checklist of potential problems that you might be able to repair. Some of these items are simple and can be done by yourself in a matter of minutes.

The 6 Step Checklist to Repairing a Broken AC

STEP 1: Is Your Air Filter Dirty?

Check it. Even if you are sure that it’s not time to change your filter again yet, go pull it out and give it a look. A filter can become dirty faster than you realize. A dirty air filter impedes airflow. It could be clogged so much that it’s keeping your AC from turning on.

If you find that your air filter is dirty, you may need to reassess how often you are changing it and start changing it more frequently. Each home and homeowners’ needs are different. Changing the air filter once very few months may not be enough for you and your home, especially if you suffer with allergies or have pets.   

STEP 2: Is your Thermostat Set Correctly?

Check to make sure your thermostat is both set to COOL and to be at least 5 degrees below the current ambient temperature.

If the thermostat screen is blank, that may mean you need to replace the batteries. For many thermostats, there is a spot along the edge of your thermostat with the word PRESS. Simply press that area to remove the battery compartment. Some thermostats will require you pull the cover of the thermostat unit off to access the batteries.

STEP 3: Is Your Power On?

Infographic explaining basic steps to resetting a tripped circuit breakerSometimes we can be surprised to find the power is off, especially in the middle of the day when we are not reliant upon lighting. If it is off, a breaker may have gotten tripped.

While it may seem daunting to deal with any electrical problem, checking your breaker box and fixing a flipped circuit is something you can try to handle yourself.


    1. Look for the switch that is in the center position.
    2. Flip that switch to off, then to on.
    3. Wait a moment for the power to return. If it doesn’t or if the switch doesn’t stay on, call a professional electrician.


STEP 4: Has the AC Power Been Turned Off?

This is a different power issue than if your entire power is out. You will want to look for a switch on or near the inside HVAC unit and make sure it is turned to the ON position. It looks similar to a light switch and can be mistakenly turned off by someone who is not aware what that switch is. When turned off, the blower would be off and can cause the inside unit to freeze.

STEP 5: Is There Ice on Your Outside AC Unit?

If ice is covering your air conditioner, turn the AC off at the thermostat and turn the FAN setting to on. Give it plenty of time to defrost. Do not try to use any sort of heating device to speed up the thawing or try to scrape the ice off.  

If this was your problem and gets your air conditioning back up and running, you should still call an AC repair technician to come out to inspect the unit. A frozen AC could mean you have a refrigerant leak which can be dangerous for you and your family.

STEP 6: Is Your AC Unit Dirty?

Even if you don’t see ice on your unit, you may find it’s covered in dirt, pollen or other debris or has debris inside the unit. Your air conditioner may be in need of a good cleaning.

To clean your AC unit, you will need to first turn it off at the outside service disconnect panel. Remove the top and any other outer caging and take out the fan. With a garden hose, spray from the inside out all around the inside of the unit. Then spray down the exterior of the unit.

Air Conditioner Not Blowing Cold Air

Thermostat set to 73 degrees, something to check when an AC blows hot air

6 Troubleshooting Steps When Your AC Blows Hot Air

Corpus Christi neighborhood, homes on Palmero St.

Your air conditioner is working hard for much of the year keeping you cool hopefully no matter how hot it gets in Corpus Christi. But unfortunately, sometimes that demand becomes too much for a home’s system. You might not always catch problems with your AC, but some problems are too obvious to miss.

An air conditioner starting to blow warm air is a major red flag that something is wrong with your home’s HVAC system. It could appear to be sounding like it’s running fine but it has stopped blowing out the cool air it’s supposed to. It doesn’t take long for a Corpus Christi home to start heating up when the AC is no longer cooling.

The good news is that even if an air conditioner is blowing warm air, that doesn’t mean it is an expensive fix. Some minor issue or one that is easy to fix may be the cause of the problem. An AC that has stopped blowing cold air may be repairable. In fact, a professional HVAC technician, like those at Tiger Heating & Air, can likely get your cooling system back up and running in no time.

Before Calling for Repair Service: Homeowner Troubleshooting Steps

Before even calling for a professional repair, you may want to check out a few things on your own. It is possible that the issue causing your AC to stop blowing cold air is so simple, you can fix it yourself!

Here at Tiger, we receive calls all the time from people across Corpus Christi in distress over a broken air conditioner. There are times when we go out to service an HVAC system, we find it only required very minor and easy fixes. While we are more than happy to service your broken cooling system, we want to provide you with information that may help you avoid having to pay for a service call altogether.

Homeowner Troubleshooting Steps for AC Blowing Hot Air

Thermostat set to 73 degrees, something to check when an AC blows hot air

#1: Check the Thermostat

Check to make sure that your thermostat is set to COOL. If it is set to only FAN or HEAT, then switch it to COOL.

And check to see if it is set to be COOLER than the current temperature. Perhaps someone changed the setting without you knowing. Just lower the thermostat setting to a number below the current temperature in your home.

#2: Check Vents Throughout Your Home

Do you see that any of your vents are closed? If so, open them. Closed vents can cause problems with the air flow and cause your AC to blow warm. It’s a common misconception that vents should be closed in room not in use, but that is not correct. While a couple closed vents may be okay, too many can cause a problem.

#3: Check the Indoor HVAC Unit

Most HVAC systems have a portion of the air conditioning system (the evaporator) located inside the home often in a closet or the attic. This evaporator absorbs heat from the air and transfers it to your outdoor AC unit (the condenser). This indoor unit has the fan that blows conditioned air through your home, and it does this even if your outside unit is not working. Check to make sure you hear the blower motor running.

Dirty air filter, something that can cause an air conditioner to stop blowing cold air

#4: Check your Air Filter

Is your filter dirty or clogged? While you are examining the inside unit, take a look at your air filter. If it is dirty or clogged, that could be the reason why your air conditioner isn’t blowing cold air. Simply changing it out for a clean air filter may get your system working correctly again.

#5: Check the Outside AC Unit

Your condenser works to create cool air that the indoor fan circulates in your home. Look at your condenser for problems. Is there frost or ice on it? What about leaves or debris?

If it is frozen or has frost, change the setting on your thermostat from COOL to FAN. Let that run for as much as 12 hours to help your unit thaw. A frozen condenser is often caused by a dirty air filter, which is another reason why making sure you regularly change your filter is so important.

A frozen unit can happen when the coils on your evaporator become dirty or clogged. If that’s the case, clean the coil if you can access it.  To get a good clean coil may require the coil is pulled out of the space it is in and Tiger can help you with that.

If you do one of these steps and it only solves your problem temporarily, you may have a more serious issue. If the AC freezes up again, call Tiger Heating & Air for 24/7 emergency AC repair service at (361) 852-4450. A freon leak could be what is causing the problem. We can come out and handle any potential leak, refill the system, and ensure it is back to working properly and safely.

Tiger Heating & Air provides 24/7 emergency AC repair service

#6: Check Your Home’s Power

If you see that your AC isn’t blowing any air at all, then another thing to check is your home’s power supply. You may have blown a fuse and need to turn a switch back on inside your breaker box.

Still confused? Call the Corpus Christi Air Conditioning Experts

When in doubt, give us a call at (361) 852-4450. We will be happy to come out and diagnose exactly what is causing your air conditioner to stop blowing cold air. We will work to quickly resolve the problem and get the temperature back down in your home.

What is the Best AC to Buy for Corpus Christi Homes?

When making a big investment for your home, you need to be sure you make the best choice for your money. Getting a new air conditioner installed is a big investment. But when it comes to getting a high-quality cooling system, it’s an investment that will pay off in more ways than one.

With a new efficient air conditioning system, you will enjoy having better and more consistent cooling throughout you home. You will also see the huge advantage of having a new AC system that is more energy efficient.

Why Quality Matters for Home AC

If you’re in the market for a new air conditioner, you should be able to get one that is going to last for more than a decade. This is why quality is so important. You need an AC to work well and efficiently every year you have it.

At Tiger Heating & Air, we see first-hand every day how important a good air conditioner is. We have dealt with air conditioners that did not last very long and other AC units that are very old and only need simple maintenance to keep going strong.

Quality also comes in play with how much your AC system is going to cost you every month on your energy bill. An air conditioner that runs at higher efficiency means a lower monthly energy bill.

A quality new AC that is professionally installed should also give you peace of mind. This should mean you don’t need to worry about potential breakdowns or other problems that can cause you problems on a very hot Corpus Christi day.

You can help your new cooling system work well for many years to come by ensuring air conditioning maintenance and tune-ups are handled on a regular basis. Most homeowners are able to handle the majority of air conditioner maintenance tasks themselves, but local HVAC companies like Tiger Heating & Air provide professional tune-up services to ensure potential problems do not get missed.

2021 Best Air Conditioner Brands

If you are looking to purchase a new AC in 2021, you should investigate different companies. There are many brands of air conditioners and other cooling units that are available to Corpus Christi homeowners. From Lennox to Carrier to Trane and Goodman, there are several well-known companies that create their own air conditioning systems. Which AC brand should you pick?

You can look to a review recently done by the online cooling & heating guide PickHvac, Trane air conditioners score best in most of the top categories. Below is a look at how Trane compares to the other big HVAC manufacturing companies. See their article for the full comparison of Trane vs other AC brands.

The AC Refrigerant You Can No Longer Get

AC technicians at Tiger Heating & Air with air conditioner in Corpus Christi HVAC shop

How the R22 Phase Out Affects Corpus Christi Homeowners

For the past few decades, a lot of the ways the world operates have changed to be better for our environment, and that is especially true in the HVAC industry. There are worldwide efforts to eliminate chemicals that hurt the ozone layer. AC systems use refrigerant, which is a known threat to our ozone layer.

The biggest regulatory change to happen recently was here in the United States at the start of 2020. Hardly any homeowners felt any impact from that change right away. But now, a year later, more people who rely on air conditioners for cooling their home will be dealing with the impact of this change.

Our team at Tiger Heating & Air stays on top of any advancements and all regulatory changes affecting the HVAC industry. We want to provide you with the information to understand this new R-22 ban so you know how to make the decisions that are best for your home and budget.

Phasing out Refrigerant 22

The 2020 change affects a chemical known as R22. It is a refrigerant that has been used since the 1950s in air conditioners for homes and businesses. The chemical is most known as Freon, which was the trademark chosen by DuPont Corporation, its first manufacturer.

Even back in the 50s when that refrigerant first came out, people were aware of the damage that refrigerants could do to the ozone layer. Refrigerants in large quantities can deplete the ozone layer and reduce the protection it gives us from the sun’s harmful UV radiation. But, ironically, that was why it was created. It was replacing more harmful refrigerants like CFC-11 and CFC-12 that were in common use at that time.

New Trane AC installed by Tiger Air in Corpus Christi, TX

Governments across the globe took on the goal to eliminate that refrigerant entirely. Regulatory steps to stop using this AC refrigerant have varied across the world. The U.K. and the European Union have already phased it out completely. While the U.S. is on a similar path, we are a few steps behind.

Here in the United States, selling any new equipment that uses it was banned in 2010. But production of it could continue. Maintenance companies could usethat AC refrigerant on already-installed air conditioning systems that are in good working order and do not leak.

But since January 1st, 2020, no more R22 could be produced. And while existing or recycled amounts can still be used on old air conditioning units, that time is almost up. We simply have no way to know how much more of that refrigerant still remains today.

Will This Refrigerant Ban Affect My AC System?

How old is your AC system? If your air conditioner was installed before 2010, it could be using that AC refrigerant. The older it is, the more likely it is using R22. If your air conditioner was put in prior to 2003, the first year restrictions on that refrigerant went into place, it is almost certainly using it.

Homes that have old AC units are the first ones to be affected by this R-22 ban. Those old units are likely to require significant maintenance work. Repairs could now cost you significantly more if that work requires adding R22, as it becomes nearly impossible to find.

Checking to See if Your AC Requires R22

Wondering if you have a system that uses it? It is not hard to find out. Go to your outdoor AC unit (the condenser) and look for a nameplate or sticker. That will list what refrigerant your system uses. You may see it as R22 or listed as HCFC-22. You should also be able to find this information in your AC’s user manual.

If you cannot find the answer, feel free to reach out to us at Tiger Heating & Air in Corpus Christi at 361-852-4450, and we will come out to inspect your system.

What is the Replacement for R22?

The replacement for R22 is R410A, most known as Puron®. It first came on the market in 1991 by the Honeywell organization. There are identical refrigerants to R410A that are available from other manufacturers under different names. This newer refrigerant is much more environmentally friendly than Freon. It does not contribute to the depletion of the ozone layer.

What if My AC Uses R22?

If you discover your air conditioner uses refrigerant R22, you do not have many options. And no matter which option you choose, you are going to have to deal with additional expenses.

You Cannot Substitute Refrigerants. Unlike being able to choose a different oil for your car, AC refrigerants are not interchangeable. You cannot just put in R410A in a system that was designed to use R22.

It is possible to have an AC system modified to work with a different refrigerant but doing this sort of retrofit is likely to eventually cost you more than completely replacing your system. Plus, this modification will probably void the manufacturer’s warranty on your HVAC equipment.

What Are Your Options?

If you have an old air conditioner and it is working just fine, you don’t need to do anything right away. But when you eventually run into needing maintenance or repair needs, you will likely be faced with making a quick decision.

Here are your three basic options:

  1. Keep your old air conditioning system and when it needs repair or any service that requires more refrigerant, opt for using recycled R22 refrigerant. However, whether this option will be available to you for long is uncertain. The cost of existing R22 will continue to rise and the available supply of it will continue to diminish.
  2. Have your R22 system retrofitted to work with R410A by a professional Corpus Christi HVAC technician. However, this will most likely void your warranty. Not only that, the expense for the parts and labor to of this modification and future service work may still end up being as much (or more) than just buying a new air conditioner.
  3. Replace your air conditioning system. This will likely be the most expensive option in the short term. But the good news is that a new AC installation is the only option that will permanently solve your R22 problem.

My Air Conditioner is Making Weird Noises

Troubleshooting Steps When your AC is Making Loud Sounds

You are hearing a noise coming from your AC and are wondering if that means there is a problem. That’s exactly what a responsible homeowner should do. While it is normal to hear some sounds coming from your air conditioning system, but sounds are signs of a problem.

Odd or new noises coming from any part of a heating or cooling system is very often an early sign of trouble. From all our experience in maintaining and repairing AC systems across Corpus Christi that we have at Tiger Heating & Air, we have an important piece of advice: Do not ignore any sound that is odd or different.

Diagnosing Problem AC Noises

AC Making odd noises diagnosis for hissing, buzzing, squealing, and clanking

We usually think of the normal sound AC units make as a hum. You also are going to hear that sudden sound of your air conditioning kicking on. These are the normal sounds that should mean everything is working fine.

These normal noises can be quite loud. Your outdoor unit, called the condenser, may be loud enough to hear when you are outside or otherwise not far from the unit. Most air conditioners run with sounds as loud as 70 to 80 decibels. For comparison, that is about as loud as a running dishwasher or nearby light traffic. If you’re googling AC noises, there is a good chance that you are hearing something different than you are used to. That still might not mean you have a problem, but it’s something to look into.

Listen closely and try to identify what kind of noise your AC is making. Depending on what the sound is, there are a variety of different types of problems that could be happening to your air conditioning system.

At Tiger Heating & Air, we regularly get calls from Corpus Christi homeowners who tell us about the odd sounds their AC is making. We have had to diagnose and fix cooling systems making a wide variety of noises. Our highly experienced team of AC repair technicians knows what each odd noise means and knows how to fix whatever the problem is. We are able to repair any brand or type of cooling system you have.

Metal or Grinding Noise

If it sounds like metal is grinding together inside your AC, that is not a normal AC noise and does indicate there is probably a problem.

Potential Cause #1: Your AC’s blower fan belts are loose or in some way damaged. That alarming noise could be the sound of the belt rubbing up on other components inside the unit.

Potential Cause #2: That sound could be coming from your compressor. What you might be hearing are pistons in your compressor not working properly.

Your Solution: Call an AC professional. If the problem is with your fan belt, it is not an repair that many homeowners can make themselves. Depending on how soon you caught the problem, this may be a quick and easy repair for our Tiger AC team to do. If the problem is with the compressor, then it might have to be replaced. Having a professional HVAC tech look at your system will mean that the right problem is identified and fixed thoroughly.

Hissing or Screaming Sounds

If you are hearing something that sounds like a hissing noise or even screaming, call us right away at (361) 852-4450. This could indicate a major problem that you do not want to wait to get addressed.

Potential Cause #1: This sound might mean you have an issue as dangerous as a refrigerant leak. Refrigerant leaks are serious, even potentially fatal, hazards to your health. It also causes further problems with your home’s system and, if left unaddressed, could damage AC valves.

Potential Cause #2: A hissing or screaming noise might mean your compression pressure has become too high.

Your Solution: First, turn off your AC. Because this sound could mean a health danger to your family, you should shut your cooling system off right away. Then call a professional to safely handle whatever is causing this sound. Call Tiger AC for service in the Corpus Christi area at (361) 852-4450. You can call us at any time. We are available for 24/7 emergency service.

Tiger Heating & Air provides 24/7 emergency repair

AC Making Squealing Sounds

Potential Cause #1: If your AC is rather old, this sound may mean there is a problem with your AC’s motor fan such as with the belt slipping (newer air conditioners do not use a belt system).

Potential Cause #2: There could be a problem with the bearings on your air conditioner’s motor fan. This is more likely if you have a new unit without a belt. 

Your Solution: Some homeowners may feel able to handle the maintenance steps in tightening up or readjusting any components that are loose. But if you aren’t confident in such DIY tasks, schedule a tune-up with a professional AC technician to diagnose and fix whatever the problems are.

A Buzzing Air Conditioner

If that humming sound has now become a buzzing sound, that could mean there is a problem. While a variety of issues could be causing it, at least one is quite serious and requires immediate attention.

Potential Cause #1: It is possible that your system has components that are malfunctioning. This might be a minor issue with loose parts or damaged feet on your outdoor compressor or the fan blades could be loose or out of balance.

Potential Cause #2: A buzzing sound could mean that you are dealing with a serious problem such as a refrigerant leak or a broken compressor. Turn off your system and call us immediately at (361) 852-4450 if you suspect this could be the case and we will come out quickly to make sure your system is safe.

Potential Cause #3: You might have an electrical issue.

Potential Cause #4: You simply have a dirty air filter.

Your Solution: Make sure your air filter isn’t dirty or clogged. Change it if it is and see if that immediately fixes the problem. If that doesn’t stop the buzzing sound, you may want to see if you can tighten a loose part or replace a missing or damaged foot. Call an HVAC professional if you aren’t able to handle those tune-ups or if that doesn’t resolve the problem. A trained AC repair technician will have the tools and experience to identify what the problem is and get it fixed.

Banging, Clanking or Rattling

Potential Cause #1: Does it sound like there is something is banging around inside your AC system? It does sometime happen that parts inside your air conditioner become loose or break off. This can cause a sound like banging.

Potential Cause #2: This sound could mean there is some issue with your compressor, and it might need to be replaced.

Your Solution: If you can find and tighten the loose part yourself, you might be able to fix this noisy problem. Otherwise, call in a professional. A loose part often will create a lot of harm to your system over time. You will want to try to get this issue fixed sooner rather than later.

Dealing with Any Weird Air Conditioning Noise

Do not ignore it. Different or odd sounds coming from your air conditioner are often clear signs that something is wrong. It is often advisable to even turn off your system if you hear concerning sounds. While there are many problems that only require a quick and easy fix, there are others that are more serious and even potentially dangerous to you and your family. You can always call us right away at the first sound of a problem and we can get you the information you need right away to make the sure to keep your family safe and system from getting worse.

Call Tiger Heating & Air at (361) 852-4450 and let us know what you are hearing.

We will be happy to come out and check your system. You will have peace of mind in knowing that an experienced AC repair technician has correctly found the problem and made sure no other serious problems exist. You will have an air conditioner working – and sounding – back to normal.

AC Repair Service Can Save You Money

Getting even minor problems fixed right away can save you money in the long run. You may even see your energy bills going down. When your system is not working properly, it is having to work harder to keep your home cool. Getting small AC issues fixed or your HVAC system tuned-up will have your system operating at peak efficiency. Not only that, but by getting needed repairs done right away means you will avoid, or at least put off, more costly repairs or even needing to get your AC system replaced.

What if My Unit is Not Worth Repairing?

It is always possible, although not likely, you have an air conditioner that is beyond repair. What you may find is that while the noisy problem can be fixed, it might not really be worth it.

There are several reasons a repair is not the right choice:

    If repair service is going to be expensive or your AC has needed several repairs recently, it may be time to replace it. AC repair costs can add up, and that money will be better spent on a more efficient system that will last you a long time.
    If your AC is at least 10 years old, it could be on its last legs. You may have to soon face even more repairs or find that it suddenly stops working. That is never something you should have to deal with in the heat of a Corpus Christi summer.
    You could have an HVAC system that is too old, inefficient, or simply the wrong size unit for your home. These are some of the top reasons that causes a cooling system to use up a larger amount of energy to cool your home. It would be smart to invest in a new system that will reduce your monthly bills with lower energy consumption.

When Your Air Conditioner is Making Weird Noises

You need to work with an experienced and qualified heating and cooling company to make sure you get a repair that fully addresses the problem. You also want a company that provides professional air conditioner installation and knows how to determine exactly the right system needed to completely cool your home. Tiger Heating & Air has been providing proven air conditioning repair service for nearly decades across the Corpus Christi area.

2023 Federal Changes on Home Air Conditioners

Old AC with low SEER rating getting replaced and is on the curb of a Corpus Christi neighborhood

New Governmental Regulations on SEER Affecting Corpus Christi, TX

Federal Restriction on Home Air Conditioners

While it’s still 3 years away, a new government rule is already beginning to impact HVAC companies like our team at Tiger Heating & Air here in Corpus Christi, TX. And at some point over the next several years, it will affect you.

Air conditioners have always had an impact on energy use and the environment. For this reason, these systems face several federal regulations. From the type of refrigerant that can be used in them to how the units are made, the government has regulated air conditioners for decades. The rules on home air conditioners sometimes change, and are about to change yet again.

How will this new change impact you, your home, and your wallet?


First Thing to Know: SEER

Understanding what this regulation change is regarding efficiency requirements for air conditioners starts with knowing what the SEER rating is.

SEER =  Seasonal Energy Efficiency Ratio. It is a rating of efficiency for air conditioners. The SEER number for an AC unit indicates its energy efficiency. The higher the number, the more efficient it is.

TEXAS AC FACTS: Typically, the AC systems operating in homes have a SEER rating between 10 – 20. For those of you with much older air conditioners, you may have a lower SEER-rated unit. And those with newer ACs may have even have higher SEER-rated systems.

For decades, the government has set mandates for how low of a SEER rating is allowed. In 1975, the U.S. Department of Energy (EPA) set the first standards for the appliances and various equipment in your home. Then the EPA set it’s first SEER rating standards in 1987.

It’s important to note that the SEER rating standards often varied from state to state. Why? The temperature and climate of the different regions across the United States can be widely different. Those factors lead to determining what minimum SEER level your AC should have.

TEXAS AC REQUIREMENT FACTS: For all of us in Texas, the current federal requirement for AC systems to have a SEER rating of at least 14.

This SEER 14 minimum rating for home air conditioners in our region began in 2015. And soon, just 8 years after the last change, the EPA is raising the SEER requirement again.


Is Your Current AC lower than SEER 15?

Tiger AC technician repairing a SEER 15 home air conditioner in Corpus Christi, TXDon’t worry. You don’t have to suddenly get it replaced, not now and not even before 2023. The raised SEER requirement that is coming is only for new AC units that are getting installed. If your AC is older with a lower rating, you will not be forced to get it replace with a newer, more efficient unit (although there are many reasons why you should consider doing just that).

As we mentioned, a lot of homeowners have older air conditioners with a SEER rating of as low as 10 right now. And that is despite the current SEER requirement for our area being 14. If you were to get a new AC installed this year, you would only be able to purchase one with a SEER of 14 or higher. And if you were to get a new AC installed in or after 2023, you would have to get one with a  rating of at least SEER 15.

The new change to the SEER minimum coming in 2023 will not force you to have to do something immediately.


Who Is First Affected by the 2023 SEER Change?

It’s mostly us, the AC companies. Beginning in 2023, Tiger Heating & Air, along with every heating and air conditioning company in our Texas region, can no longer install an air conditioning unit with a SEER rating of 14 or less. The new federal regulation means all ACs we install will be SEER 15 or higher.

Because our climate varies widely across the country, it’s a different situation in other states than for the Texas AC requirement. For HVAC companies in states further north, they do not have as high of requirements. For our northern friends, they will only be permitted to install air conditioners with a minimum rating of SEER 14 starting in 2023.


How Will You be Affected?

To put it simply, you likely won’t be affected by this regulation change. This SEER 15 minimum rule will only be a potential issue for homeowners who need to replace an aging cooling system on or after January 1st, 2023. If that happens to become your situation, you probably will still not be significantly impacted by the raised SEER standards.

Old AC with low SEER rating getting replaced and is on the curb of a Corpus Christi neighborhoodHVAC technology has come a long way over recent years. Not only do you have a wide variety of cooling systems to choose from, you have great and affordable options to increase your energy efficiency.

If your current AC breaks down and you do need one in 2023 (or even before then), there is a good likelihood that you will not even consider a system that is less than SEER 15. For not much of a price difference, you can buy an air conditioner with a high SEER rating that runs more efficiently and puts out more reliably cool air.

Rarely does a homeowner in Corpus Christi choose a SEER 14 (or less) air conditioner. When you hire Tiger for a professional AC installation, we’ll provide you all the information you need to consider the options and benefits of different systems. We will help you to determine the AC that is right for your home.

Why do most people already choose cooling systems with a high SEER? One reason people decide upon a higher SEER rating is that it will save them money. The amount of money you spend every month on your energy bills will be greatly reduced by a higher efficiency unit. Over time, you’ll see that the money you are saving on your monthly energy bills may even make up for the cost of installing a more efficient unit.


Bottom Line: The Impact of the 2023 SEER 15 Rating Change

As we’ve explained, homeowners across the Corpus Christi area will face minimal impact with this upcoming regulation change. If you are working with a trusted, professional heating and air company, they’ll explain why a higher SEER rating is beneficial for you. This increased efficiency standard may force those who are reluctant to pay a little more for a better system.

The U.S. Energy Information Administration states that these increased standards for SEER will add up to a savings of $2.5 billion to $12.2 billion on energy bills during the first 30 years that the 2023 regulatory change takes affect.
