please help-any advice on the differences/quality of the 3 brands i have offers on:
1. AMANA/AMS9/ACS9 single stage 60.000btu 93% AFUE
2. LENNOX GSIMP36B70-70,000 btu 92% AFUE
3. RHEEM-RGRA09 90,000 BTU 93% AFUE
We are replacing a 90,000 btu lennox about 17 years old. My home is about 1200 sf to heat (3rd story) no ductwork.
I'm really lost trying to determine which brand best fits our needs. We replaced all windows in the house in past 5 years.
One installer said perhaps 2-stage furnace another said absolutely not needed. I live in Western PA where winters can get cold.
Any help please is much appreciated.
