When summer heat and humidity make you feel like a wet dishrag, you don’t want warm air blowing from the AC. Depending on the reason why it’s happening, you might or might not need to call an air conditioner repair service. Here are a few factors that may be bringing the heat instead of the cool breezes.

Why Warm Air Is Coming From Your Air Conditioner

1. Thermostat Controls Need Adjusting

The thermostat regulates the temperature, and if the controls are not properly set for air conditioning, you feel warm air blowing. Before calling an air conditioner repair company, check the thermostat to make sure it is set to “cool,” not “heat.”

The fan should be on “auto” with the temperature set at a level below the actual indoor temperature. A range between 72° F and 78° F keeps most people comfortable.

2. Air Conditioner Filter Is Clogged

When the filter is clean, the evaporator coil removes the warmth from the indoor flowing air, and the fan blows the cool air on you. However, when those materials clog the filter, the coil can’t do its job, so the fan blows warm rather than cold air.   

3. Evaporator Coil Is Dirty

If you change the air filter and still get warm air, the problem might be that the evaporator coil itself is dirty. To ensure the evaporator coil is cleaned properly and safely, make an appointment with a professional HVAC technician for air conditioner repair assistance.
