A good fit if…
- Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 18,000 BTU/h at 5°F.
- You want steady temperatures and quiet running - the compressor varies its speed.
Think twice if…
- Cooling cost matters most - its SEER2 is below average for mini-splits.
- You mainly need heat - its HSPF2 is below average for mini-splits.
