Search through all the Lennox air handlers. If you're replacing a whole system, you might need:

Filter by BTU and model family first. The check cabinet width against the closet of your current air handler or platform.

An indoor blower only delivers rated comfort when it is matched to the outdoor section. Pair these units with a matched outdoorair conditionerorheat pump. Some jobs also need a separateevaporator coilpath, or a furnace when gas heat replaces electric strip heat.

In plain terms, this aisle is theair handling unitroom: the indoor section that moves conditioned air through the ducts.

We confirm compatible indoor/outdoor combinations before you buy. AHRI pairs stay off this page until we verify them with you.

Capacities on this aisle run about 18,000–60,000 BTU — a catalog fact, not a square-foot stamp. No sq ft chart here; bands would still be a starting point before a Manual J.

Cabinet widthon listed SKUs is about 18.5", 21.25", or 21.5". Measure the closet or platform before you shortlist.

HVAC USA does not publish a Manual J tool. We can help set a sane starting size before your installer runs the load calc.

Shortlist indoor units with the filters, or note the tonnage and family you already know. We confirm outdoor/indoor matchups before you buy. You complete the purchase online once the SKUs are locked.

Manufacturer coverage and registration windows depend on model and purchase/install path. We will confirm warranty years before you buy. Do not assume full OEM terms on an internet purchase without a licensed install and registration path.

Plan the full matched job:

  • Matched outdoor condenser or heat pump plus this indoor air handler
  • Line set sized to the actual run
  • Electrical disconnect and whip; thermostat / control as specified for the system
  • Optionalelectric heat kitwhen strip heat is part of the design — confirm ECB / ECBA family match before you buy (we do not invent a kW matrix here)
  • Licensed startup and refrigerant work — not DIY

Freight expectations: see ourshipping policy.

It is the indoor blower that moves conditioned air through the ducts. It pairs with an outdoor air conditioner or heat pump. It is not a gas furnace — heat comes from the heat pump and/or optional electric strips.

Capacity, refrigerant generation, metering device, and airflow have to line up. We confirm the combination before you buy. This page does not invent AHRI pairs or refrigerant claims.
