Replacing Gas Heater
I am just getting started on shopping for a new gas heater only. My 4 ton A/C system is all new. I do have my first quote which raised additional questions. I live in Tulsa, the house is all brick, built in 93, 1900 sq ft. There is no nameplate on the excising unit.
ONG is offering a $550 rebate for HE units over 96%
The equipment in installed in my attic and I have read many comments here about problems with HE units installed in attics, but no explanation.
My first bidder mentioned that he had to oversize the heater to 100k in order to get enough airflow for the 4T A/C. If this is true; I think I should be looking at variable speed units.
Trane XV95 $3814
I am starting to lean toward a 80%, VS unit.
