Heat Pumps

Each unit here is the outdoor half of a ducted split system. It needs a matched air handler, or a furnace with an evaporator coil, to deliver its rated efficiency.

Lennox Heat Pumps

Lennox models here use R-454B refrigerant and run from 15 to 21 SEER2. The Merit ML14KP1 and Elite EL16KP1 are single-stage. The Elite EL18KSLV, EL19KPV, and EL21KLV are variable-speed, and Lennox positions the EL21KLV for low outdoor temperatures. See every model on the Lennox heat pumps page.

Trane Heat Pumps

Trane models here run from 14 to 20 SEER2. The single-speed units, at 14 and 15 SEER2, cover 1.5 to 5 tons. The variable-speed units, at 17, 18, and 20 SEER2, cover 2 to 5 tons. Shop them on the Trane heat pumps page, and call us to confirm the refrigerant and indoor match for any Trane model.

SEER2 and HSPF2

SEER2 rates cooling efficiency and HSPF2 rates heating efficiency. Both are system ratings, so the numbers that count come from the AHRI certificate for your outdoor and indoor match. Ask us for the matched ratings before you order. Climate, backup heat, ducts, and placement still affect what you get.

Sizing

One ton equals 12,000 BTU. The right size comes from a Manual J load calculation that accounts for insulation, windows, ducts, and climate, so square footage alone can't set it. An oversized heat pump short-cycles and hurts humidity control, and an undersized one runs constantly and leans on backup heat.

Cold Climate and Dual Fuel

Low-temperature heating capacity depends on the model, the size, and the indoor match, so bring your winter design temperature to the call. For dual fuel, pair a compatible heat pump with a gas furnace and a matched coil, and the controls switch between heat pump heat and gas heat. That takes a full equipment and controls design, and we scope it with you before you order.

Match the Indoor Side

Pair the outdoor unit with an air handler, or with a furnace and an evaporator coil. We confirm the AHRI-certified match with you before you order. If you only need cooling, compare air conditioners.

FAQ

Can I pair a heat pump with my gas furnace? Yes, when the heat pump, furnace, coil, and controls are designed as a compatible set. We match those pieces with you before you order.

Should I choose Lennox or Trane? Choose on the efficiency, staging, and price that fit your home, and on which brand your contractor is certified to install and register. That certification is what keeps your full warranty in place.
