Until recently, I had no know-how of heat exchangers.
I didn’t realize that it is really the most important plus costly area of a gas gas furnace.
I also never considered that failing to have my heating plan professionally diagnosed would lead to such a large problem plus expense, but my gas furnace was only six years old when it started to have problems. It was suddenly running for excessively long cycles yet failing to meet the temperature control setting. It simply is not putting out enough hot air to keep the apartment comfortable. I noticed that the rooms of the apartment were all unusual un-even temperatures. There was a significant amount of dust floating around plus an unpleasant stink. I should have called for professional maintenance immediately. I kept hoping the gas furnace would somehow repair itself. I was reluctant to take a day off from work to meet a service professional. I didn’t want to spend the money on repair. I procrastinated until the gas furnace eventually quit altogether. When the professional took the plan apart, he pointed out the buildup of dust clogging all of the components, however he explained that the debris within the inner laborings had jammed airflow plus restricted the moving parts, causing the gas furnace to work harder. The plan had eventually hot. I expected the professional to scrub the component plus maybe upgrade a few parts. I assumed the maintenance would be fairly costly but completed abruptly. Instead, he informed myself and others that there was a crack in the heat exchanger. The crack was so small that I couldn’t even see it. Because the heat exchanger is the component that prevents carbon monoxide plus other combustion byproducts from entering the breathing air, it’s super important. It also costs more to upgrade than buying a whole current gas furnace.
