What Should You Do If Your AC Is Blowing Hot Air?

It is concerning to experience your AC breaking during peak summer days. When this issue happens, the first thing you should inspect is the thermostat. If your air conditioner is blowing hot air, the thermostat may have been fixed to “heat” by mistake. If this is the case, it is simple to repair yourself. Return the thermostat set up to “cool” and check if the air conditioner starts blowing cool air again.

Additionally, ensure that the battery packs are operational and that the temperature is not set too high. Remember that the “auto” function only uses the fan when the air is heated or cooled. However, hiring a professional Avondale AC contractor if the issue happens is more complicated.

Reasons Your Air Conditioning System is Blowing Hot Air

Here are some evident reasons your cooling device is not blowing hot air:

  • Breaker Circuit

After verifying the thermostat batteries and settings, check the wiring closet to ensure the HVAC system is powered on. Heating and cooling device units consume a lot of energy to operate. When there is an excessive power demand, the circuit breaker may immediately close off power as a protective measure. Look for a tripped circuit breaker in your AC’s electrical panel. 

Flip the AC breaker off (opposite direction of all the other fuses) and then to the “on” position to restore power to the unit. If you have an overheated fuse, you must replace it. It could also be a suitable time to label all of your circuits for easy comparison the next time an overloaded circuit occurs.

  • Dirty Air Filter and Evaporator Coils

Although air filters have no bearing on air temperature, a clogged air filter can lead to a clogged evaporator coil. When the evaporator coil becomes congested with dust and debris, there may be insufficient free airflow to allow proper- cooling operation. A clogged air filter accumulates debris, leading to frozen evaporator coils. You might think that “frozen” means “cool air,” but the frozen coils obstruct cool airflow, resulting in warm airflow from the running motor instead. Therefore, replacing the air filter every 30-60 days is better, depending on the climate, filter type, and residence.

  • Faulty Condenser Coils

After checking the thermostat, splitter box, air filter, and indoor coils, it’s time to review the exhaust system. Like the indoor evaporator coils, the outdoor evaporator coils require free airflow. As a result, a 2-foot clearance around the outdoor condenser unit is suggested at all times. If your outdoor unit becomes clogged, turn it off at the source. Then, wearing gloves, remove the larger items and rinse away the smaller wreckage with your garden hose. It is better to understand the accurate ways to clean your outdoor condenser unit point by point.
