American Standard, 4 ton 13 seer quote -- any help appreciated
We're in central Virginia and have a dual zone HVAC system for a 2650 sq. ft. house (not including recently finished 800 sq. ft. basement -- so 3450 total).
Downstairs/basement has 1992 American Standard AC unit (4 ton, 10 seer) and separate gas furnace (with radiant heating in some areas); upstairs has 2004 American Standard (2.5 ton, 11 seer) AC/heat pump.
Earlier this week, our downstairs 10 seer unit leaked all of its freon. Tech says there are multiple perforations in the aluminum coils, and that at this point it make sense to replace the unit.
Two issues: (1) he quotes a price of $3200 for a new American Standard, 13 seer AC unit; and (2) recommends against replacing with a heat pump, because city gas prices are reasonably low.
Any thoughts on this? I'm obviously not an HVAC person and would appreciate any help. Thanks --
