Welp, 2021 just took an abrupt face-heel turn. My furnace is down for the count. It started making worrisome noises on Thursday, I had my father-in-law (who owns and runs a heating/plumbing business) take a look at it. He told me to take apart and adjust the alignment of the blower wheel. I took it apart, and… it wasn’t the blower wheel. The blower motor is on its last legs. His heater guys are both out of town, so I may wind up having to replace the motor myself. (Or call someone from another firm, which would cost me major coin.) For now, space heaters are running all around the house.
