An HVAC air handler is like a big fan. Its job is to push the cooled air that passes over the air conditioner’s evaporator coil into your Titusville, FL, home’s ducts. The pressure created by the air handler pushes the cooled and dehumidified air all the way through the vents and into your living space. Be aware of these three common problems with your HVAC air handler.

Clogged Air Filter

Your cooling system’s air filter is located within the HVAC air handler. A clogged air filter hinders airflow. You’ll notice that barely a trickle of air comes out of the vents. The air conditioner may short cycle, and your utility bills will go up. Check the filter monthly. Replace it when it’s dirty, and don’t wait longer than three months between filter replacements.

Slow Fan Motor

The HVAC air handler’s fan is powered by a motor. The motor needs regular maintenance, including cleaning and lubrication. According to the Department of Energy, a dirty filter could cause the air handler’s fan to prematurely fail. Signs of a failing fan motor in the HVAC air handler include loud grinding or squealing sounds during cooling cycles and low airflow. Once the fan fails, the air conditioner won’t work. This requires professional attention from a qualified service technician.

Dirty or Frozen Evaporator Coil

If you notice water dripping or a puddle near your HVAC air handler, this is related to a dirty evaporator coil. Closed supply vents, dirty air filters and missing an annual AC tune-up are some common reasons why evaporator coils get dirty. A low refrigerant charge also leads to frozen coils. Failing fan motors and electrical problems with the condenser reduce airflow over the evaporator coil, which can cause it to freeze.
