    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.

    first of all.....after Jan 2006 noone is allowed to manufacture 12 SEER any more... 13 minimum.
    heat pumps are better choice. cheaper to run than gas down to about 25 30 degrees then gas takes over. The heat pump is an air conditioner too.... Best choice IS ground source if ya wanna pay the up front hit on the price of it.
