Simple Solutions For Fixing Your Central Air Conditioner When It's Blowing Warm Air

If your air conditioner has suddenly started blowing warm air, you may wonder if there is anything you can do yourself to resolve the issue without having to call in a repair service. If so, try the following simple solutions to fix your central air conditioner when it is no longer cooling your home.

Check Your Thermostat Settings

The first thing you should check when trying to determine the problem with your unit is the thermostat settings. Even if the temperature is already set to the one you desire, look at the switch for the fan.

If the fan setting has been turned to the "on" position, this means that your air conditioner's fan will always blow, even when the condenser is not switched on. As a result, the unit will pull in warm air from the outside and circulate it throughout your home.

During hot weather, make sure the fan is switched to "auto." With this setting, the fan will only run when the condenser is on, blowing in only cold air that has passed through the system.

Replace the Filter

Another simple fix you can try when your air conditioner is not adequately cooling your home is replacing the filter with a new one. For your AC unit to work, it has to have enough air flow passing through the system.

When your air conditioner's filter is clogged up with dust and dirt, the air is partially blocked. Because the air is no longer freely flowing through the unit, the amount of cool air the AC unit can create becomes limited. Make it a habit to change the filter at least once a month. 

Clean the Cooling Coils

Another part of your air conditioner responsible for cooling your home includes the cooling coils. Found inside the AC unit, these coils are responsible for the exchange of heat from your home with cold air from the unit.

If these coils become dirty, the heat is unable to radiate off of them so that it can be cooled, resulting in the warm air blowing back into your home. To clean the coils, turn off and unplug the unit, then wipe the coils with a damp rag to remove any dirty film on their surfaces.

If your air conditioner is still blowing warm air, the unit may be low on refrigerant or may have a mechanical issue. Contact an air conditioning repair technician to have them inspect the system so that the necessary action can be taken to fix it.
