Hello HVAC Pros:
I'd like to know the payoff period in Delaware/Philly area for upgrading to a 90% Gas furnace as compared to an 80%.
Also what's the pay-off period to go from 10 to 12 or 13 SEER.
btw: is Ducane brand reliable?
Also: I was wondering if any of you would be interested in a furnace & a/c replacement job on a "Time and Materials" basis - meaning I buy the furnace and a/c and you do the installation.
Thanks in advance.
