Buying guide
What the 36K BTU class holds
Everything rated from 33,000 to 38,999 BTU lands on this page, because units sell by the nearest size class: 26 products right now, including 6 air handlers, 5 wall-mount heads, 2 ceiling cassettes, 1 slim duct unit, 1 floor or ceiling head, 8 single-zone outdoor units and 3 multi-zone outdoor units.
A 36K unit suits roughly 1,200 to 1,800 sq ft with 8 ft ceilings and average insulation. Ceiling height, insulation, sun, windows and a kitchen all move that number, and the sizing guide shows by how much; the system builder does the math for each room.
Brands at this size: Cooper & Hunter. SEER2 ratings run from 15.8 to 24. Voltages on offer: 115–208 V and 208–230 V.
A head at this size pairs with an outdoor unit of the same class for one room, or joins a multi-zone system as one of its zones. Each product page lists the pairings the manufacturer approves.
Common questions
Can I install a mini split myself?
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.
How do I know what size I need?
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.
Do you ship nationwide?
Yes. Every system ships to all 50 states.
Can I return a unit?
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
Not sure which size?
The builder sizes each room and shows only the pairings Cooper & Hunter approves. The sizing guide explains the rules behind it.
A person checks the pairing on every order before it ships.
