What to look for
- Cold-climate rating if you have real winters — check capacity and COP at 5°F.
- SEER2 / HSPF2 efficiency and ENERGY STAR certification (for incentives).
- Single vs multi-zone — match the number of heads to the rooms you want to control.
- Local support and warranty terms.
Size before you buy

Frequently asked questions
What is the best mini-split brand?
Mitsubishi, Fujitsu, Daikin and LG are all well regarded. The right size and a quality install matter more than the brand.
What size mini-split do I need?
Size each room separately — roughly area times a climate factor. A 400 sq ft room typically needs a 12,000 BTU head.
Are cheap mini-splits worth it?
Value brands can be fine for mild climates, but for cold winters invest in a cold-climate-rated unit and a good installer.
