First, thanks to all for your help in the past
Via advice on this forum I am improving my home for eventual purchase of a new AC/heat pump. Working on the house (better attic venting, more insulation (R-38 now), solar screens, indoor storm windows, caulking, etc.) has made a significant difference. I am in West Texas and we are expected to get to 96 today and 98 tommorrow and it's just April!!!
But, I wanted to ask a heat pump question. I know about the primary value of a good install. If you read this site and don't get that, you shouldn't be allowed to drive or operate machinery. I really don't want to ask about brand but it may be inevitable. My question is who DESIGNS the best or better heat pumps. I read that in the old days GE stuck with and "perfected" heat pumps, and then sold out to Trane/AS. I don't have to purchase the very best, but I would like to know who designs good, solid, durable long-lasting heat pumps. I'm just asking about the heat pump component, not air handler, controls, etc.
