An HVAC air handler is indoor equipment that moves conditioned air through a duct system. Depending on the application, it may contain a blower, evaporator coil, filter provisions, controls and optional electric heat.

No. An air handler primarily circulates conditioned air and may use electric auxiliary heat, while a furnace includes a fuel-fired heating section. The correct indoor unit depends on the HVAC system design.

Yes. Air handlers are commonly paired with compatible split-system heat pumps for heating and cooling.

Yes, when the air handler and outdoor air conditioner are an approved compatible match for the application.

Many residential air handlers include or are designed around an indoor refrigerant coil, but construction varies by model. Verify the exact equipment specifications.

A variable-speed air handler uses a blower motor and controls capable of adjusting airflow over a range of operating conditions when paired with compatible equipment and controls.

A multi-position air handler is designed for approved installation orientations such as upflow, downflow or horizontal configurations. Allowed positions vary by model.

Many compatible air handlers can accept optional electric heat kits for auxiliary or supplemental heat. The heat kit must be approved for the specific equipment and properly sized and installed.

The air handler should be matched to the outdoor equipment, required airflow, heating and cooling load, duct system, electrical supply, refrigerant, controls and manufacturer-approved combinations.

Correct matching helps ensure capacity, efficiency, refrigerant compatibility, controls, airflow and manufacturer requirements are satisfied.

Yes. Incorrect airflow can contribute to comfort problems, reduced efficiency, coil freezing, humidity issues, noise and equipment problems.

Often the indoor and outdoor equipment should be evaluated together. Compatibility, refrigerant, efficiency certification, age, condition and manufacturer requirements determine whether an existing air handler can remain.

The refrigerant depends on the matched system. Newer HVAC systems may use lower-GWP A2L refrigerants such as R-32 or R-454B, while existing systems may use other refrigerants.

The air handler is central to filtration and airflow. Compatible filters and indoor-air-quality accessories may be integrated depending on system design.
