Everything you read online about heaters says you should consistently wipe them. If you leave a furnace dirty, then havoc ensues. A dirty furnace can genuinely overheat and catch on fire. The air filter can only stop so much dust from going into the system, then once the dust gets in the inner workings and the surance struggles to maintain heat, there is your fire hazard. Another occasion is carbon monoxide. While the furnace strains to achieve the control unit setting, the heat exchanger can crack. This releases carbon monoxide into the home, which is a tasteless, smellless, and poisonous gas. The only way to detect it is through a carbon monoxide detector. The only way to avoid it is with usual furnace cleanings. I am on top of it with furnace service. I have a Terrell, TX furnace service and service company that is amazing. They show up on time and do routine service once a year. They check for dust, rust, and coercion. They change my air filter, wipe the inner workings, and inspect every itn top to bottom. Typically they find nothing. This most recent time there was just a small worn part. It only cost me about 300 bucks for the part and labor. I was cheerful to pay for it. I feel anytime they catch a furnace service is ideal. That part could have genuinely graduated into total system failure. It is almost better when they catch something. That way I can justify it in my head that my furnace service is a smart investment every year. I prefer all the benefits I get from it.
