Sometimes, you try everything you can to fix something, and for no clear reason, things don’t get any better.
I’d better narrow down what I’m driving at, because I guess that statement can apply to everything from relationships to your car.
I purchased my current home 5 years ago. I never found out from the previous homeowners how old the furnace was. It initially seemed to be working just fine. I was wise enough to change the air filters and have HVAC technicians do all the necessary checkups and tune-ups and cleanings. Then, overtime, this regular maintenance routine just didn’t seem to be cutting it anymore. The way I first noticed it was my energy bills. They slowly but surely started creeping up, in the winter especially. I pay attention to these things, because I painstakingly budget everything. It comes with the territory of being an accountant, I suppose. Anyway, I asked my local HVAC service what might be happening. They told me everything checked out in terms of the health of the furnace unit. Then things got worse. The heater seemed to run, but the various rooms in my home got ever so slightly cooler and cooler every night. It got to the point where there were distinct cold spots here and there scattered throughout the house. It took a while for an HVAC technician to eventually admit to me the truth. At the end of the day, as a furnace ages, its efficiency begins to wane. It may not break down completely, per se, but it will eventually cost far more to run it, yet you’ll be getting far less heat than you started out with! That same HVAC technician advised that it was time for a new furnace. I hate that he’s right but I’m tired of shivering at night!
