We live in a 1200 SF 1976 ranch house (all roof and basement) with electric heat and appliances. I was thinking of having a air source heat pump installed to supply heat and and AC. I have added 6 inches of unfaced insulation to attic and don’t feel that running ducts thru that unconditioned area and low slope acess with an R-8 insulation rap would be beneficial. I was wondering if installing the air handler and ducts in the basement would be better. Are there any concerns for this approach? Thanks for your input. Glenn
