Did you get a Mr. Cool brand heat pump? Because those are garbage. Had a friend that bought one online from Mr. Cool, and it just ran like crazy, power bill went way up and then it died.

We have two Daikin pumps and they work great. 3100 sq ft house is heated well, we have a oil boiler we really use for hot water now. Its only been a few weeks, but they have handled the cold well.

We've got solar so we banked tons of credit last summer, so our CMP bill is steady at $13.73/month every month.
