What to Do When Your Air Conditioner Is Blowing Out Warm Air

A reliable air conditioning system is an essential part of any home. And this is especially true during the hot summer months. Not only does a reliable air conditioning unit keep your home cool and comfortable, but it also helps to protect your furniture and flooring from potential damage caused by excessive heat and humidity.

Without an air conditioner, your home would quickly become unbearable during the summer months, making it difficult to sleep or relax. But sometimes, your air conditioner may not be able to keep you as cool as you want. And this may be because it is blowing out warm air instead of cool air.

Check the Thermostat

If your air conditioning unit is somehow blowing out warm air, the first thing you should check is the thermostat. If the AC’s thermostat is set to “cool” and the temperature is above the set point. This will get the air conditioner to cycle on and off, trying to reach the set point. When the thermostat is set to “heat,” the air conditioner will not come on.

Check the Air Filter

If your air conditioner is still blowing out warm air, and it’s not because of the thermostat, you should check the air filter. A clogged AC air filter can cause your air conditioner to blow out warm air. To check the air filter, remove it from the air conditioner and hold it up to a light. If you can see the light through the filter, it’s clean. If you can’t see the light through the filter, it’s clogged and needs to be replaced.

Check the Coolant Level

If the coolant used in air conditioners is low, the unit will be unable to generate enough cold air to keep your home comfortable.

There are a few ways to check the coolant level in your air conditioner. The simplest is to look at the pressure gauge on the unit. If the needle is below the “normal” range, then your air conditioner is low on coolant.

Another way to check the coolant level is to listen to the unit. If you hear a hissing sound, that means there’s a coolant leak. You’ll need to have the leak repaired before adding more coolant to the unit.

If your air conditioner is low on coolant, you can add more yourself. However, it’s important to follow the instructions in the owner’s manual carefully, as adding too much coolant can damage the unit. If you’re not comfortable adding coolant to the unit yourself, you can call a professional from Legacy to do it for you.

Check the Condenser Coils

If your air conditioner is still blowing out warm air and you’ve already checked all of the above, the next thing you should check is the condenser coils. These coils are responsible for dissipating heat from the refrigerant, so if they are dirty or damaged, the AC will not be able to cool properly.

You can clean the condenser coils yourself with a brush and some detergent. Or better yet you can hire a licensed HVAC professional from Legacy Heating and Cooling to do it for you. If the coils are severely damaged, you may need to replace them.

Once you’ve checked the condenser coils, if the air conditioner is still blowing out warm air, there could be a problem with the air conditioner’s compressor. This is a more serious issue and will require a professional to fix it.

Final Thoughts

There are a few reasons why your air conditioner might be blowing out warm air. It could be that the unit is too old and needs to be replaced, the coolant levels might be low, or there could be an issue with the compressor. If you’re not sure what the problem is, it’s best to call a professional to take a look.
