Air handlers vs furnace vs air conditioner

Unlike furnaces and air conditioners that create heated or cooled air, air handlers circulate air that's already been heated or cooled by another source. In other words, air handlers work with your existing air conditioner, furnace, heat pump or boiler to regulate and distribute hot or cold air evenly throughout your space.

How air handlers work

Air handlers are made up of two main components: a blower fan and an evaporator coil. Simply put, air handlers draw in warm or cool air from inside your space, pass it over the evaporator coils to cool or heat it and then blow the conditioned air back out into your home or business through the duct system.

Benefits of air handlers

If you're thinking about upgrading your HVAC system, you may want to consider getting an air handler for the following reasons:

1. Better indoor air quality.

Modern air handlers have sophisticated filtration systems that capture microorganisms, dust particles, pet dander and bacteria before spreading throughout your property. Moreover, your HVAC system will perform more efficiently by catching and eliminating pollutants before they pass through your ductwork.

2. Save on energy bills.

Variable-speed air handlers run continuously at low speed. This prevents your HVAC system from turning on and off unnecessarily and using excess power. Consequently, you can save money on your energy bills.

3. Consistent comfort.

Air handlers help keep the air in your home or business at a stable temperature, resulting in fewer hot and cold spots. They also help remove excess humidity from the air.


If you have any questions about air handlers or want one installed in your home or business, the Aire One Heating & Cooling team would be happy to help.
