We had a technician from a local HVAC company do an inspection/tune-up on our gas furnace a few weeks ago. I wasn't home when he was here. He told my wife that the heat exchanger is showing a weak spot---he said he could tell from the color of the metal---and is due to fail at some point in the near future. He told her the reason for this is because we have been using the 1/2" thick metal mesh filters which were previously used in conjunction with electrostatic filters (which we stopped using), as well as a standard disposable corrugated fabric furnace filter. This, he claimed, starved the furnace for air and led to overheating. Is this plausible? If so, what would be the immediate effect of the heat exchanger cracking during use? There is no emergency gas shutoff to deal with this situation.
If my tone makes it sound as though I'm suspicious, that isn't entirely the case. It's just that I would be more comfortable accepting the information if it didn't come from someone who has something to sell me.
Thanks,
Stan
