Air Handler
Definition and meaning of Air Handler in real estate.
An air handler is the indoor component of a central heating and cooling system that contains the blower, heating or cooling elements, and filter. It works in conjunction with an outdoor heat pump or air conditioner to circulate conditioned air throughout a home.
In more detail
Unlike a furnace, which generates heat internally, an air handler simply moves air across coils containing refrigerant or hot water. It is connected directly to the home's ductwork system, distributing air to various rooms and returning it for conditioning. Inside the air handler, you will find the blower motor, the evaporator coil, and the air filter compartment.
Regular maintenance, such as replacing the air filter and cleaning the coils, is essential for maintaining energy efficiency and indoor air quality. If the air handler fails, the entire HVAC system cannot distribute air, rendering it unusable.

Frequently asked questions
Is an air handler the same as a furnace?
No, a furnace burns fuel or uses electricity to generate heat, whereas an air handler contains a blower and coils that rely on an external source like a heat pump to heat or cool the air.
How often should the filter in an air handler be replaced?
Filters are typically replaced every one to three months, depending on the type of filter, the presence of pets, and the frequency of system use.
