Air Handler Maintenance St Louis – Keep Your HVAC System Efficient and Effective

You want to keep your HVAC equipment working as efficiently and effectively as possible. Part of that process if you have a boiler or a heat pump is maintaining your air handler. Just like every machine or piece of HVAC equipment, it is important to perform regular care and maintenance services to it. Doing so helps prevent breakdowns, reduces repairs, and increases the longevity of your equipment.

Air handlers should be serviced twice a year – once of the warmer months to ensure cool air flow to your home or business and once for the colder months to be sure your property stays warm and cozy.

A typical air handler maintenance appointment typically includes:

  • Changing the air filter
  • Cleaning the air handler cabinet, blower fan, evaporator coil and other heating elements
  • Oiling the blower motor components and gauging its current and voltage
  • Replacing or adjusting the fan belt as needed
  • Checking for loose connections (electrical or in ductwork)
  • Verify air flow, refrigerant charge, and blower speed
  • Flush the condensation pan


Performing this regular maintenance has the added benefit of preventing bacterial or mold growth as well as dust buildup and spreading allergens, which also helps it all run more efficiently. It can benefit your budget as well. According to the Department of Energy, “The difference between the energy consumption of a well-maintained heat pump and a severely neglected one ranges from 10% to 25%.”[1]

FAQ’s About Air Handler Maintenance Services

What is the difference between AC and air handler?

Air handlers move already conditioned (warm or cold) throughout a property’s ductwork. An AC unit conditions outdoor air to feel cool.

Yes, an air handler always resides in the home as part of the HVAC system to blow warm or cold air into the ducts to be distributed throughout a home or business.

What maintenance does an air handler need?

Air handlers need maintenance like any other component of your HVAC system, including:

  • Lubricating the motor and blower bearing
  • Straightening coils
  • Checking that all moving parts are operational and there are no loose or damaged connections
  • Air handler repair may be required if not maintained frequently.
