Why Isn’t My Air Conditioner Cooling The House?

June 18, 2020

Numerous problems, some more apparent than others, can be preventing your air conditioner from doing its job. If you’ve noticed issues like warm spots in rooms or longer cycling, then the following could provide an explanation.

Clogged Air Filters

The air filter in your return vent should be replaced regularly (every 30 days for fiberglass filters and every 60 to 90 days for pleated filters), or else the pollutants that it traps will block airflow, preventing cool air from getting to your rooms. Clogged air filters are one of the leading causes of uneven cooling.

Dirty Evaporator and Condenser Coils

There are two coils in a ducted AC: the evaporator coil in the air handler and the condenser coil in the outdoor unit. The former absorbs heat from the circulated air, while the latter releases it. If either coil becomes clogged with dirt or, in the case of the condenser coil, outside debris like leaves and twigs, then the AC won’t deliver so much cool air.

Air Leaks in the Ductwork

If some areas are warmer than others, it could be that the ducts leading to those rooms are leaking air. Leaking ducts can reduce energy efficiency by 20%, according to the EPA, so it pays to have a well-designed and well-sealed duct system.

Improper Refrigerant Charge

Every air conditioner comes with specific rules concerning the charge, or amount of refrigerant. It’s possible that whoever installed your unit put in too little refrigerant.

Lack of Routine Maintenance

All of the above issues can be pointed out during a professional tune-up. At ACR Air Conditioning & Heating, we offer regular maintenance for homeowners throughout Lake Charles, LA. We believe that maintenance isn’t just an optional add-on; rather, without it, you’ll only continue to see poor performance together with higher energy bills.
