Troubleshooting Common Furnace Problems

Is your furnace not heating correctly or not working at all? Not all furnace issues require major repairs – sometimes it is just a small issue that you can fix yourself. Here are some troubleshooting tips to determine what is causing the problem and whether you need to call a professional.

Check the Air Filter

A clogged air filter can cause all types of problems. Air filters should be changed about every 30 days. Make sure your filter is not clogged and change if needed. Turn off furnace first, then check or change the filter. Also, make sure the furnace panel is completely closed – some models will not turn on if the panel is not tightly closed.

Check the Thermostat

Make sure your thermostat has good batteries and try setting the temperature higher to turn the furnace on. You can also open the cover and carefully dust the components to ensure the connections are clean.

Check the Vents

Are all your vents clear and open? Make sure rugs, furniture or other items are not blocking vents and stopping the air flow in the home.

Check the Pilot Light

If you have a gas furnace, your pilot light should be a blue flame. If is red, purple or orange, call your HVAC professional right away. If the pilot light is out, it will need to be relit. Turn off the gas for 10-15 minutes before you re-light the pilot using the manufacturer instructions.

Check the Electric Panel

If you have an electric furnace or your furnace requires electricity, check the electric panel for blown or flipped fuses.

If you check all these issues and your furnace still is having problems, it is time to call the HVAC professionals for a furnace repair or replacement.
