Air Handlers & Fan Coils

Air handlers, or fan coils, are responsible for circulating the heated or air conditioned air throughout the home. Essentially, the air handler is one of the most important parts of your heating and cooling system! Without a well-functioning air handler, your home will not reach the comfortable temperature you desire.

At Michael Bonsby HVAC, Plumbing & Electrical, we have been repairing and replacing air handlers for more than 20 years. Contact us today to schedule service in Maryland and Washington, DC.

What Is an Air Handler?

An air handler is a small metal box that circulates air throughout the home that contains:

  • A blower fan driven by an electric motor
  • Coils for both heating and cooling
  • A filter
  • A set of controls

The air handler’s job is to supply conditioned air to the occupied spaces in your home. In smaller HVAC units, this job is handled by the fan coil, which houses all of the necessary systems in one unit that is not connected to any ductwork.

While older, single speed air handlers were largely inefficient, newer models have two speed or variable speed air handlers that adjust to their most efficient levels based on how much heating or cooling the air in your home needs.

Variable-Speed Air Handler Installation & Replacement

If you want to get the maximum efficiency out of your air handler, consider installing a variable-speed air handler as part of your HVAC system. Variable-speed air handlers have a number of benefits when compared with single-speed air handlers:

  • Variable-speed air handlers cost less to operate– Since they spend most of their time running at a low speed, variable-speed air handlers do not need nearly as much energy to operate as single-speed air handlers and therefore cost less to run.
  • Variable-speed air handlers do not blast air– Because they can work their way gradually from low speed to high speed, variable-speed air handlers do not blast air from vents when they turn on. In fact, the transition can be so mild you might not even notice when your variable-speed air handler kicks on!
  • Variable-speed air handlers are quiet– Since they usually run at low speed, variable-speed air handlers are much quieter than single-speed air handlers.
  • Variable-speed air handlers can create heating zones– Variable-speed air handlers can be programmed to supply different amounts of air to different rooms, making them effective zoned heating systems.
  • Variable-speed air handlers can help curb humidity– Variable-speed air handlers can help control humidity in your home without making the air feel dry. Some variable-speed air handlers are so effective at removing humidity they can pull as much as 24 gallons from your home’s air per day!
