11 Tips for DIY Furnace Repair & Maintenance

Cleaning Gas Furnace with VacuumWhen it comes the important things in chilly Minnesota life—like a working furnace—sometimes they can be in need of repair at the most inopportune times.

Yes. Furnace repairs can sneak up on homeowners. But before you panic, there may be a few furnace repairs and maintenance items you can take on yourself.

Below are some of our top DIY furnace repair tips that just may get your furnace back in working order—without calling in the professionals:

1. Change your furnace filter.

Your furnace filter has a big job to do, and during months of high-use it can get pretty clogged up and dirty. A dirty furnace air filter can cause poor air flow and definitely doesn’t support good air quality. We recommend changing your air filter about once every three months, but check the manufacturer’s recommendations as well.

2. Check out burner flames.

Your burner flame should be burning evenly and blue. If the flame is yellow, that’s typically a sign of dirty burners, but it could also be a sign that your furnace is producing carbon monoxide. If you’re concerned about carbon monoxide, call a professional to take a look.

3. Vacuum burners.

Turn off your furnace system as well as the gas supply and then vacuum any dust in or near the burners, blower compartment or furnace base.

4. Clean the blower.

Clean blower blades with a vacuum and small brush, but be careful not to disturb the counterweights or wiring.

5. Clean the flame sensor.

We suggest using a fine emery cloth, which is made to clean metal surfaces.

6. Dust the pilot and hot surface igniter.

We suggest using a drinking straw to blow off any dust that may have built up on the pilot or the hot surface igniter. Note: do not touch the hot surface igniter.

7. Check the drive belt for wear and tear.

This is something that should be regularly checked, and is inexpensive to replace. The cost for a new belt is about $5 or so.

8. Lubricate bearings.

Many furnace systems have motor bearings and blower shaft bearings that should be lubricated yearly with just a few drops of lightweight motor oil.

9. Look for corrosion.

Look for a white, powdery substance on an exhaust vents as this could be a sign of corrosion. A professional can make any necessary repairs here.

10. Seal leaks in vents.

If during your vent inspection you noticed a leak, use metal tape or heat resistant silicone to seal them up.

11. Check air intake and exhaust pipes.

If the air intake pipe on the exterior of your home is blocked, your furnace is likely not running properly. Be sure to clear away debris such as snow, ice or leaves from exterior furnace exhausts.

    Thanks for these great tips! I just moved into a new house and have been trying to make sure it’s all prepped and ready for winter. I definitely want to make sure my furnace is working properly, and my repairman has already suggested a few parts that could stand to be replaced. Once that’s done, I’ll make sure to keep up on maintenance like changing the filter every three months this winter like you suggested!
