AC Problems That Could Require Repairs To Get Your Home Cool And Comfortable

When your air conditioner isn't working, the AC repair technician has to determine if the problem is with the condenser parts or in the air handler. Each has parts that can malfunction and cause your home to be too warm. Major parts in the air handler that might be to blame are the blower and evaporator coils. Here's a look at problems that might arise with these two parts that could keep your home from cooling down.

Clogged Filter

The air handler needs a good amount of airflow to blow across the evaporator coil and to help the blower produce a maximum amount of air. If you forget to change the filter, it could get matted in dust and the dust mat will restrict airflow. The solution for restricted airflow is to change the filter and make sure nothing else in the AC system is blocking air.

Blower Parts

The blower system consists of a fan, capacitor, and motor. The fan might get loose and not produce very much airflow, and this would probably cause a rattling noise to alert the repair technician to the problem. If the capacitor or motor goes bad, they might make odd noises too. An AC repair technician can replace the capacitor and motor if needed and clean and tighten the fan. This should get the fan working at full capacity so the right volume of air is sent through the ducts.

Evaporator Coil

The blower blows air across the evaporator coil as the air heads for the ducts to spread cool air through your house. If there's a problem with the evaporator coil, it may not be able to cool the air enough. Problems with the coil include it being covered in grime or coated in ice.

The coil might also develop pinholes that allow refrigerant to escape, and when refrigerant is lost, your AC can't keep you cool. The AC repair person may need to scrub the grime off of the coil or defrost the ice so they can look for pinholes. If the holes are present, they need to be repaired so the refrigerant can be filled. Once the refrigerant is back to the proper level, the AC should start cooling.

The AC repair technician can use tools and refer to the error codes on your air handler to narrow down the problem. Blower issues are fairly common, especially bad capacitors, so they may look for the most likely issues first. Plus, the technician can feel the temperature and amount of air coming out of the ducts to know if the problem is with the blower and airflow or the evaporator coil and the refrigerant.
