Looking for some advice here guys. I'm buying a house and the Fedders furnace (105,000 BTU) was estimated to be over 30 years old by my home inspector. So I asked that the furnace be replaced by the seller. The seller will only replace it if the HVAC tech determines that it needs to be replaced.
So I guess I'm asking what I should ask the HVAC tech when he's there? What might the technician be looking for to say it needs to be replaced other than a cracked exchanger?
The furnace is working but I don't want to be stuck with something that should be replaced soon just b/c it is working.
According to the inspection report, it was a Fedders, Model No. CF656837. But I'm not 100% sure that # is right, according to Fedders that model was mfgd in '94. No way this thing is that new.
Here's a pic of some pretty good rusting in the burner area from my report.
Thanks for any advice!
