Interesting development. Had to get the furnace fixed yesterday. The guy from a month ago never came back. Just disappeared with my money. So the nice guy comes yesterday, fixes the problem, then says the furnace desperately needs cleaning, and probably hasn't been cleaned in about 70 years.
I say come on back when you can, and you can do my T drop for my gas booster (for torching) while you're here. He comes back today, does a GREAT job on the T, then starts to clean the furnace.
As a long-time homeowner, I can tell you that it is NEVER good news when a service guy in the basement says, "Mrs. Kesling, can you come down here a minute?" He opened up the furnace to find a gaping hole in the heat exchanger, and there are way elevated carbon monoxide levels here. We have to replace the furnace.
Here's the thing: Apparently, all of my symptoms COULD be related to carbon monoxide poisoning!!! I even called my doctor, and he agreed. Even the chest pains! Flu-like symptoms, difficulty breathing... Maybe this is the source of my trouble?
So tonight I have to get a carbon monoxide detector, and try not to use the furnace until we can get it replaced. I am very lucky in that I had the presence of mind to buy home warranty insurance when I bought this place. I had let the policy lapse, but was still within the grace period, so I renewed. There is still no guarantee that they will pay for all of it, but I'm guessing they will pay something.
I'm just glad I decided to have him come back and clean it. It very well might have saved our lives.
