What Is An Air Handler?

Your air conditioner has many parts. The air handler is typically the gray metal box that sits outside your home. This component is one of the most important parts of your AC system because it is home to all the major cooling parts, blower motors, fan belts, and other vital parts of the system. If there is a problem with the AC, chances are, it has something to do with the air handler.

If the air handler fails or the outside case becomes damaged, it’s important to get it fixed or replaced right away. A cracked or dented air handler requires immediate new air handler installation because the physical damage could lead to contamination and a snowball effect of problems with the system.

    Signs You Need Evaporator Coil Repair Or Replacement

    The evaporator coil is the component that works to cool and condense returning air from the system. If the coil becomes dirty, it will freeze and stop working.

    Other signs that your evaporator coil needs service include:

    • Uneven temperatures in your home
    • Excess humidity levels
    • The AC turns on and off repeatedly without changing the temperature
    • Warm air coming out of the vents
    • Strange noises coming from the condenser unit as it overworks to make up for a broken coil
    • Clanging sounds coming from the air handler
