Air Handlers

An air handler is the indoor half of a split HVAC system. It contains the evaporator coil (where refrigerant absorbs heat from indoor air), a blower motor (which pushes conditioned air through your ducts), and often an optional electric heat kit. If you're buying an AC condenser or heat pump with an all-electric setup, yes — you need a matching air handler. If your home has a gas furnace, an evaporator coil mounted on top of the furnace does this job instead (shop our Evaporator Coils collection for that).

Three things need to match: (1) tonnage — 2.5-ton condenser = 2.5-ton air handler; (2) refrigerant — R-32, R-454B, or R-410A; (3) AHRI rating — the pair must be certified together to hit the advertised SEER2. Our complete system bundles handle all three automatically. If you're buying standalone, use the Tonnage and Refrigerant filters above, then confirm the AHRI match with us at (352) 438-8992.

ECM (Electronically Commutated Motor) blowers are variable-speed — they ramp up and down based on demand, like a car's cruise control. They run quieter, use less electricity (typically 30-40% less), and maintain better humidity control. PSC (Permanent Split Capacitor) motors are fixed-speed — on or off, nothing in between. Almost all modern air handlers are ECM; you'll only see PSC on entry-level builder-grade units or very old stock.

You can replace just the air handler if the refrigerant matches your existing outdoor unit. But heads up: if your condenser is more than 8-10 years old, replacing the air handler alone is often a short-term fix. Mixing an old condenser with a new air handler means you'll never hit the newer unit's efficiency rating, and you'll likely be replacing the condenser within a few years anyway. Worth pricing out a full system replacement before committing.

Only if you're pairing the air handler with a heat pump AND you live in a climate cold enough to need backup heat (roughly, anywhere north of Florida). The heat kit is electric resistance heating that kicks in when the heat pump can't keep up on the coldest days. Size ranges from 3kW (mild climates) to 20kW (very cold climates). If you're pairing with an AC condenser only (cooling), no heat kit needed. Heat kits sold separately.

Multi-position air handlers can be installed four ways: vertical upflow (air blows up), vertical downflow (air blows down), horizontal left (air flows sideways with drain on the left), or horizontal right. This flexibility covers 95% of residential installations — closets, basements, attics, and utility rooms. A few specialty models (like the Everwell Front Return Wall Mount on this page) are dedicated to a single orientation but offer a smaller footprint for tight spaces.
