Small ducted heat pump?
My wife and I are 69. We’re in the process of designing a house for our retirement with our architect. It’s going to be a “pretty good house” with a very small heating/cooling load. Neither my wife nor I think the ductless minisplits are all that attractive, AND the air filters would be hard (relatively, because of the height) likewise for the “ducted” minisplits that I’ve found via Mr Google. ( they’re all ceiling mounted and we’d like to avoid having to get on a step ladder to change air filters as we get older & older). We’re looking for something like a conventional heatpump (ducts & all), that the air filter(s) would be easier to access. Any suggestions.
