Central Air Handlers | Multi-Speed & Variable ECM Fan Coils

Air Handlers

Air handlers are the indoor component of a central HVAC system that move conditioned air through your home’s ductwork. They work with either an air conditioner or heat pump to distribute cooled or heated air evenly across rooms, making them essential for consistent comfort and proper system performance.

In modern HVAC systems, air handlers are designed to improve airflow efficiency, humidity control, and overall temperature balance—especially in larger homes or zoned systems where stable air distribution matters.

What you’ll find here

Central air handler units for split systems
Heat pump-compatible air handlers
Multi-position air handlers (upflow, downflow, horizontal)
Variable-speed and ECM motor air handlers
Low-profile air handlers for tight installation spaces
AHRI-matched indoor units for complete HVAC systems

How to choose

Match the air handler capacity with your outdoor condenser (tonnage must align)
Ensure compatibility with your system type (heat pump or AC-only)
Choose variable-speed motors for better comfort and humidity control
Verify airflow (CFM) matches your duct system size and layout
Check physical dimensions for installation space constraints
Confirm refrigerant compatibility (R-32, R410A, or system-specific)
Consider noise levels for indoor placement near living areas

Air Handler vs Furnace Blower

Air handler: Used with electric AC or heat pump systems, no gas heat included
Furnace blower: Part of a gas furnace system that provides both heat and airflow
Air handlers: Common in all-electric or heat pump HVAC setups
Furnace systems: Used in gas-electric configurations for stronger heating in colder climates

FAQ

What does an air handler do?
It circulates conditioned air through your duct system after it has been cooled or heated by the system.

Is an air handler the same as a furnace?
No. An air handler moves air, while a furnace generates heat using gas or electricity.

Do I need an air handler with a heat pump?
Yes. The air handler distributes the heated or cooled air throughout the home.

Can air handlers be used with AC systems?
Yes. They are commonly paired with central air conditioners in split systems.

Do air handlers use electricity?
Yes. They power the blower motor and internal controls, typically using efficient ECM or variable-speed motors.

Do air handlers require professional installation?
Yes. Proper installation ensures correct airflow, refrigerant connection, and system efficiency.
