I think I told y'all we'd had to replace one of our air conditioning units here a while back. So I got a quick education on stuff like variable speed compressors, SEER ratings, and rebates. We've always had pretty high cooling bills in this house in the summer and as a result we keep our thermostat turned up as high as we can manage so the dang things (we have three units) don't run 24X7. The old unit was installed when we built the house and had a SEER rating of below 6, and the new unit has a SEER rating of 17.5/96.5 efficiency and is a two stage unit. Because the thing has a low speed function that essentially dehumidifies, we've had to turn our thermostat from 73 all the up to 79 just to keep it from being too dang cool in the house. It does run some on the high speed side but not nearly as much as the old one. I can't wait to see our first electric bill to see how much our usage has dropped.
Hell, if I'd have know this I would've changed the damn thing out long before it ever went out. As it is, I think I'm going to change at least one of the other two units out next year!
I never thought I'd be comfortable in this house at 79!
