I am relocating from the Northeast to Richmond, VA. One of the options I have in my new house for heating and cooling are: heat pump or A/C with gas furnance. This will be a 2-story house. First option: 2 12SEER heat pumps or upgrade to 13SEER heat pumps. Second option: 12SEER A/C w/ 90% gas furmamce and 12SEER heat pump on second floor. Which option would be best?
I think I can also do 13SEER with 905 gas variable speed furnance. Any thoughts on Geo-Thermal system?
Any information would be greatly appreciated.
