If the house has ducts, a ducted inverter heat pump keeps the vents and replaces the old furnace-and-condenser pair with one system. The catalog carries PEAQ inverter systems, multi-position air handlers that install upflow, downflow or horizontal, and A-coils for pairing with an existing furnace, from 18,000 to 54,000 BTU.
Electric heat kits add backup heat for the coldest nights; they are not sold on the site right now, so call and we quote the kit that fits with your order. A whole-house load depends on more than square footage, so call for the sizing on these; the room sizer on this site is for single zones.
Mounting, wiring and running the line set are within reach of a capable DIYer. The refrigerant connection, vacuum and charge should be done by a licensed HVAC technician in most states, and most warranties require it. We can point you to an installer in your area.
Use the system builder: enter the rooms and it sizes each one and shows only manufacturer-approved combinations. For vaulted ceilings, sunrooms or very old houses, call and we will size it by hand.
Yes. Every system ships to all 50 states.
No. All sales are final, so size it right first: the builder and the sizing guide are free, and a person confirms the pairing on every order. If anything arrives damaged, we handle the claim for you, and defects are covered by the manufacturer warranty.
Sizing help
The builder sizes each room and shows only the pairings Cooper & Hunter approves. The sizing guide explains the rules behind it.
