no, it never really crossed my mind about the heat pump....almost
no-body has one, so I don't know.

if the unit costs $3500 for a 13 SEER, XR12, R22, 10-5-1, then do you
think it makes sense to try and get the $4300 14SEER, XL series,
10-10-2 ?? even if I get the 10-10-10 for $400 on the other model,
I'm still only $400 away from a better unit outside, higher SEER, and
newer technology.....just some thought, not to mention the free
electric filter thingy.
