This has been discussed before, but after our experience of the past 3 weeks I thought I'd weigh in. We left TX on our way to Dubois, WY for the summer. From Raton Pass to now (about 3 weeks) all our nights have been at over 7000' and the temps have been from 28 to 36 degrees. On the one night that it got down to 28 the furnace kicked in, otherwise all our heat has been from our 1 heat-pump. I set the thermostat at 60 and still need to keep most of the bedroom vents closed to keep it from getting too hot in the bedroom. It then takes about an hour to get the living room temp up to 68 in the morning. From this experience I think my decision to only get one heat-pump and a smaller a/c in the bedroom was a good one. The reason for the smaller a/c in the bedroom is that it will run on even a 20A service for those time when we camp in some of the old northern CGs.
