This heat pump performs admirably!
September 14, 2026
We are extremely happy with our choice!
Hard working heat pump
September 12, 2026
Amazing heat pump saved plumbing this cold winter as propane company failed to install tank in time. Has 10 year’s warranty but I was unable to get extended service contract locally. It is not variable speed and no fan control so my furnace fan blowing on max which is annoying. Overall I am happy with performance and installation.
Stackable system
September 11, 2026
Great product, like the stackable feature. Quite, high performance and seems to be energy efficient for the value.
Disappointing
September 8, 2026
This is a very noisy unit and sounds like a semi truck.
My review
August 30, 2026
Suggest the unit come with more substantial guard over the heat exchanger fins and distance is needed between the guard and the fins.
