I have an American Standard 80,000 BTU 2 stage furnace (new)
AUH2B080A9V3VA and it was installed with an AmericanStandard
Coil model 4TXCB036BC3HCA. 3 ton coil
Now want to install/ add AC was quoted
1 American Standard Allegiance 16 SEER 4A7A6036B1000A
for $4500 plus electricians charge. Was told by another
that the coil doesn't match right with this system and
SEER will drop to 14.5. Do you know if this is correct?
2 Also quoted AS Allegiance 15 SEER 4A7A5030E1000A for $3453 plus electrician. Will the SEER drop on this one too?
Should I have a different coil?
Is price good or not? IF price not so good what should I shoot for?
House is a raised ranch in Mass 1300 feet on top floor, 450 feet living space on first floor, good attic insulation, good windows, wall insulation a bit weak.
The 16 SEER I think is 3 ton and the 15 is 2.5. Any thoughts on what size to go with?
Any guidance would be appreciated.
