Terrible idea. 98% of inspectors don’t know dick about newer furnaces (made within the past 15 years). I had a guy tell a customer of mine one time he couldn’t figure out why their furnace had two heat exchangers (all 90%+ do) and also that there were definitely no cracks in either of them (there was one about the thickness of a dime, which in the HVAC world is gigantic).
If push comes to shove Sean and you need the furnace legitmately checked out, let me know and I’ll send a service tech over for half price ($35) and do a full diagnostic on the system. Otherwise like I said above if you just want a simple look over and price workup, let me know and I’ll do it for nothing whenever you have some tme.
