The main function of your air conditioning unit is to circulate cold air throughout your space to combat the heat. From mechanical malfunctions to routine wear, there are several reasons the appliance could fail to do its job. If the device starts blowing warm air, it’s best to call an air conditioning repair specialist immediately. Continuing to use the unit will diminish indoor air quality further and lead to higher energy bills. Below are common reasons an AC system blows warm air and what to do about it.  

4 Reasons the AC System Is Heating Your Home

1. Clogged Air Filter

Over time, the AC filters designed to keep debris out of your air supply will become covered in dirt, dust, and other particles. This restricts airflow out of the unit, which means it will be difficult to circulate cold air throughout the space. Changing the filter once a month during the cooling season should prevent clogs.  

2. Loose Outdoor Condenser Plug

If the air conditioner components inside the house seem to be in working order, inspect the exterior equipment. Often, when the indoor fan is running but the air remains warm, there could be a loose connection to the outdoor condenser. If you don’t see physical signs of damage, secure the plug back in the unit and check that thermostat settings are in the “cooling” mode. 

3. Leaking Refrigerant 

Refrigerant is like the blood for your air conditioner. Housed in the coils, the liquid dehumidifies and cools indoor air. Refrigerant leaks diminish the system’s cooling capacity and could send toxic fumes throughout the house, so call an air conditioning repair specialist for help. Damage to mechanical components or faulty installation could be to blame for the issue.

4. Dirty Evaporator Coil

Similar to a clogged filter, a dusty evaporator coil will also restrict airflow, leaving interiors warm or muggy. It’s in the evaporator coil where refrigerant absorbs heat. A dirty coil makes the heat transfer difficult, which causes the system to expel warm air. Call an air conditioning repair specialist for help. They have the tools to remove panels from the blower cabinet to access the interior coil assembly for cleaning.
