Why Is My Air Conditioner Blowing Hot Air?

You’re in your home when you feel a drop of sweat creep down your forehead. You start to think that’s weird because your air conditioner should be on cool.

The problem you are facing is one that many homeowners have. So, why is your air conditioner blowing hot air? There are many reasons this could be happening.

Read on to find out the most common causes.

Incorrect Thermostat Temperature

If your air conditioner is blowing hot air, the first thing you’ll want to do is double-check your thermostat. It’s possible that you accidentally set your thermostat to heat.

If this is your problem, you’ll be glad you checked instead of calling a residential AC maintenance service.

Your Unit Lost Power

Air conditioners are made up up an indoor and outdoor units. If the outdoor unit lost power, it could be causing your AC to blow hot air.

The cause of this could be the circuit breaker or a blown fuse. You can check your circuit breaker and fuse panel to see if this is the problem, but you will need to have it resolved by a professional.

Low Refrigerant

The AC unit might be low on refrigerant if the air in your home is warm. If this happens, you probably have a refrigerant leak somewhere in the system.

The air conditioner will work over time to try to reach the temperature your thermostat is set to but be unable to because of the leak.

An HVAC technician can figure out where the leak in the system is and repair it for you. After repairs and restoring refrigeration levels, your problem will be solved.

Dirty Evaporator Coils

Keeping your evaporator coils clean is one of the keys to keeping your home cool. If your AC is blowing warm air because of a dirty coil, you’ll need to complete an air conditioner tune-up.

Likewise, you’ll want your air filters to stay clean. Air filters won’t affect the temperature in your home, but they can cause your evaporator coil to get dirty.

If the evaporator coil is covered in debris or dirt, cool air won’t come from your system. Regular AC maintenance can help you avoid this issue in the future.

Clogged Condenser Coils

If you’ve checked your indoor evaporator coils and don’t see an issue, the problem could be stemming from your outdoor condenser coils.

These coils need free airflow that can only occur if they are unclogged. To clean the condenser coils, you’ll want to turn off your unit and rinse the debris off. You can do this with a garden hose.

Are You Taking Care of Your Air Conditioner?

If you keep up with regular maintenance and cleaning for your air conditioner, you should be in good hands. However, leaks and a loss of power can occur at any time.

If you can’t find the issue when your AC unit is blowing warm air, seek out a professional AC company for help.
