Why it matters
The Cooper & Hunter 36,000 BTU 230V Mini-Split is rated at 36,000 BTU of cooling. On the ENERGY STAR room sizing chart that suits about 2,000 to 2,500 sq ft of average room; the maker says up to 600 sq ft. It needs a 230V (208/240V) circuit, which usually means an electrician if one isn't already at the spot.
Its 19.5 SEER2 ranks 2 of 5 among the mini-splits within about 12% of its capacity that we cover; the most efficient is the TOSOT 33,600 BTU 230V Mini-Split at 21. The maker says heat-pump heating keeps working down to -13°F outside, hyper-heat territory.
Expect a professional install: the copper lines are connected, pressure-checked and vacuumed before the refrigerant is released. The kit includes a 16FT insulated copper line set. It uses R-454B refrigerant, one of the lower-impact A2L refrigerants new systems moved to in 2025.
The listing gives dimensions of 16.14 inD x 37.24 inW x 31.89 inH, a shipping or unit weight of 320 pounds, a 10,549 W power draw and 16ft insulated copper line set, 16ft communication cable, 16ft drainage extension in the box.
Who it's for, and who should skip it
Good fit if
- Rooms of about 2,000-2,500 sq ft
- Cold-climate heating
- Lower running costs than most same-size systems
Look elsewhere if
- Spaces much larger than 2,500 sq ft
- Owners who want to avoid a licensed install
Pros and cons
Pros
- 19.5 SEER2
- Heats down to -13°F
- 16FT insulated copper line set included
Cons
- Heating capacity not stated on the listing
- Needs a 230V circuit
- Professional install recommended
Limitations to weigh
- Capacity and efficiency are the maker's ratings; real output depends on the install, the line length and the weather.
- Heat pumps lose heating capacity as it gets colder; size for your climate with the BTU calculator.
- The federal 25C tax credit ended for systems installed after 2025; check your utility for current rebates.
