There are few things worse as a homeowner than a malfunctioning furnace. But the unfortunate fact is, eventually, we all deal with maintenance issues regarding our home’s heating system. While you definitely will want to get your furnace repaired as soon as it’s stopped working, there are some things you can look for to diagnose issues early, possibly saving you on a more expensive furnace repair or replacement.
A dirty or clogged filter can reduce the intake your furnace needs to function, reducing its efficiency.
It could also potentially lead to the damage of your limit switch. Ensure your filters are swapped out once a quarter to ensure peak performance. If your limit switch isn’t functioning properly, you’ll notice that your furnace may be continually blowing, even when it shouldn’t be. Unfortunately, replacing this requires a professional technician. Are you hearing a popping, pinging or rattling noise coming from your furnace? These could be caused by several issues. Rattling noises are usually related to loose panels on the furnace that need to be tightened. Pinging or popping noises are likely due to the ductwork.
