I'd appreciate some professional advice on my situation as described below.
I have a 17 year old Bryant gas furnace in my home. I have never had any problems with it in the 2+ years I've been in the house. I decided to have a cleaning & "tune-up" done recently. The tune-up was completed and the technician said there were no problems with the unit...only said it was old. About six hours later the unit was short-cycling...the burner was going out only 15-30 seconds after lighting. A second technician arrived to troubleshoot the problem and, after 2 hours of tinkering, determined I had a cracked heat exchanger!
So in an 8 hour period I've gone from a perfectly functioning, albeit older, furnace to a condemned POS. I'm obviously aware that the furnace was near the end of it's life expetancy, but it's a bitter pill to swallow that I had preventive maintenance done and it turned into a replacement.
My question is: Is there any chance that the maintenance performed may have caused the heat exchanger to crack in a six hour period?
What recourse do I have with this maintenance company to work out a deal for a replacement furnace?
Any advice is much appreciated in this dicey situation. Thanks in advance!
