Most Common Furnace Repairs for New Homeowners

When you buy a home with an existing furnace, you have to trust that the previous homeowners kept up with maintenance and took care of the system. Unfortunately, that’s not always the case. Many new homeowners have to get furnace repairs done sooner rather than later.

If you bought a home recently and want to stay ahead of furnace repair in Saint Michael, MN, our team can help. It’s not too late to begin scheduling maintenance regularly to prevent future furnace repairs.

Keep reading to learn about the most common furnace repairs we see.

Blower Fan Issues

It’s common for fan blades to bend and scrape or come loose. You may hear a clicking sound if the fan blade is bent just a little. If the damage is more severe, the sound will be louder and more noticeable. Keep in mind that the sound can change over time as the fan blades bend more or become looser. The belt attached to your blower can also get loose or break, causing the furnace to stop working completely. If the belt is loose you may hear it screeching too.

Clogged Burners

If you have a gas furnace, it’s possible for the burners to malfunction. Sometimes the burners get dirty and need to be wiped down or cleaned out–something only a trained technician should do. Other times, ignition doesn’t happen as soon as it should because of a problem with the igniter itself. In either case, burner problems let gas build up in the chamber leading to a small explosion when ignition finally does happen. 

Air Filters

If the homeowner before you did not change their air filters regularly, dust and dirt may have built up in the system. Our team can wipe down the inside of your furnace and change a clogged air filter. But after that, we advise you try to keep with changing the air filter on a schedule so the problem doesn’t happen again. 


Sometimes the problem is not actually with your furnace, it’s with your thermostat. Your thermostat may be miscalibrated and not communicating correctly with your furnace. If your thermostat doesn’t tell your furnace when to turn on and off correctly, it may seem like your furnace isn’t working. The good news is, this is usually an easy fix. We can either recalibrate your thermostat or replace it with a new one. 


If the electrical panel is older, it may not be able to handle the load of your furnace. If too much power surges to your furnace, it might trip the breaker. If this happens frequently, then you need to get both your furnace and electrical panel looked at. Your furnace may not be the problem. Instead, your electrical panel may be limiting what your furnace can do. Upgrading your electrical panel can be a big project, but it’s worth it to have the peace of mind that you can run your furnace without tripping breakers.
