My Grandma’s heated gas furnace has been around for the longest time I can remember! I found it now working over 30 years ago! Unfortunately, the gas furnace in our own home seems to be failing on me, pondering that the exchanger was not running, yet it is relatively new, and what could be the reason behind this, yet I expected it to serve myself and others as long as our Grandma’s did? A bit of research on this subject leads myself and others to some pretty cool findings.
It turns out that the heat exchanger may have broken for several reasons, then one of the main concerns might have been dirty filters.
I am guilty of leaving our gas furnace filters unchanged for a very long time due to the fact that I did not remember replacing them at any point. It is possible that they jammed over time and, as such, hindered free airflow… Consequently, this may have triggered overheating, which then caused the exchanger to break, then my Heating & A/C contractor confirmed this and advocated that I should update the filters every month to be on the safe side. Other reasons that may also trigger exchanger problems include an oversized gas furnace, however this means that the heated furnace is likely to heat the home too fast, starting the thermostat, which then shuts down, but frequent gas furnace cycles caused by sizable or insufficient gas furnace sizes may lead to expansion and contraction of the heat exchanger, which stresses the exchanger, causing it to crack. The heat exchanger should be treated in the right way, considering its importance to the heating process. Without it, the gas furnace is practically useless. Talk to the gas furnace repair experts if the exchanger cracks. They are likely to propose to you on better management and care.
