Only Warm Air is Flowing from my Air Conditioner. Do I Need AC Repair?

Man checking thermostat on wall

On a hot summer day, the first thing you do when you get home is make a beeline for the thermostat to cool things off. After a few minutes of waiting, it doesn't feel one degree cooler and, as a matter of fact, it feels like it may have actually gotten warmer. You check the vent and sure enough, the air conditioner is blowing warm air.

Here are some troubleshooting steps you can take when your air conditioner is on the fritz.

Double-Check The Thermostat

This is likely the easiest step you can take. Make sure the temperature setting is what you intended and that this setting hasn't inadvertently been set to heat rather than cool.

Check Your Air Filters

When was the last time that your air filters were replaced? Dirty air filters can reduce the airflow in your home resulting in your air conditioner blowing warm air. For the average home with no pets, consider changing your air filters once every three months. If you live in a home with pets or someone with allergies, you may need to change your air filters more frequently.

Check The Coils On The Air Conditioning Unit

Similar to the air filters in your home, if the coils are dirty on your air conditioning unit, airflow can become restricted, reducing the ability to blow cool air. It is recommended that you have your air conditioning unit serviced at least once a year to prevent issues like this.

What About The Electricity?

it's possible that electricity is not getting to the outside unit. While your air handler on the indoor portion of the unit may be working, without the outside condenser unit, the air cannot be cooled. Check your electric panel to determine whether or not a fuse is blown, or the breaker was tripped.

When You Need The Assistance Of A Professional

If you've tried to take steps to troubleshoot the issue on your own and the problem still persists, you may need to call in the experts. Here are some issues that may require the assistance of a professional to resolve.

Air Conditioner Low On Refrigerant

If your air conditioner is low on refrigerant that means there is a bigger issue that should be addressed. The refrigerant is the stuff that flows through your air conditioning unit and makes the cooling happen.

Ordinarily, the refrigerant stays within the unit and does not need to be changed. A reduction in the amount of refrigerant in the unit means that there is a leak. The leaks should be addressed prior to refilling the refrigerant.

Return Air Duct Is Broken Or Disconnected

If the air return duct has become broken or disconnected, that means that cool air from the air conditioning unit is not being pulled into your home. Rather warm air from your attic or outside (depending on where the problem is) is being circulated in its place.

This could occur as a result of an accident during a home improvement project or birds or animals causing damage. You should find an expert to take a look at your ductwork and make any necessary repairs.

Trouble With The Compressor

If none of the other issues seems to resolve the problem, the trouble may lie what the outside unit. A professional will be able to look and help you to determine what the issue is. They can advise you on what happens next.
