Payne gas heating system for sale. Design PG8DAA048095. This furnace did an exceptional task of heating up a 2400 square foot home; must be around 100,000 BTUs; I believe the real output is 92,000. 80 % efficient (see image # 2). It is in exceptional condition. Produced and skillfully set up brand-new in 2002 (see last photo). The unit has been under contract for routine service and repairs its whole life; I can probably get service records if you are interested. In 2010 the blower motor was changed and it works fine. I am changing the device just due to the fact that I have needed to install brand-new central air which sits under the heating system, and the installer provided me a great discount on a brand-new, more efficient unit, in addition to cost savings on labor due to the fact that I am doing both tasks at the same time.
