I’m glad the HVAC system has so many safety features

If the HVAC is struggling with the air flow due to a clogged up air filter, it can cause the HVAC system to overheat, and naturally it will restart if this is the case

I was really concerned the other day when my furnace was having trouble starting up. I was thinking that the ignitor was going bad or something was wrong with the furnace. Then I remembered that I forgot to change the air filter. It must have been 4 months since the last change and that was going overboard even for a 3 month air filter. So I changed the air filter and immediately, the next time the furnace clicked on, there was no trouble with the furnace starting up. I couldn’t believe the difference it made just by changing to a new air filter. It really is something amazing and I learned a lot about it the next time the HVAC worker came over to our household to do HVAC system maintenance. He was saying that it’s all about the airflow in the system. If the HVAC is struggling with the air flow due to a clogged up air filter, it can cause the HVAC system to overheat, and naturally it will restart if this is the case. So the reason why my furnace kept restarting before turning on was because it detected an insufficient amount of airflow due to the clogged up air filter. That was very enlightening and I find the HVAC system to be very interesting with the way it works and all the safety features. If we didn’t have so many important safety features with the HVAC, we could be in serious risk with carbon monoxide poisoning or having the HVAC catch on fire from actually overheating.
