A good fit if…
- You want a certified 2-ton central heat pump at a typical efficiency level.
Think twice if…
- You often see nights below 0°F - it is not cold-climate certified.
- Cooling cost matters most - its SEER2 is below average for central heat pumps.
- You mainly need heat - its HSPF2 is below average for central heat pumps.
