5 Most Common Furnace Problems

You probably don’t give your furnace much thought – until it fails. The good news is that many furnace problems are easy to correct. While it’s advisable to hire a professional when your furnace isn’t working properly, there are some issues that you may even be able to fix yourself.

1. Clogged or Dirty Filters

Issue: Dirty or clogged air filters restrict airflow, causing your furnace to work harder than it needs to, making it less efficient.

Solution: Regularly check and replace filters every one to three months to keep your furnace in good working order and to ensure maximum efficiency.

2. Wear and Tear on Furnace Parts

Issue: Over time, components such as belts, bearings, and motors can wear out, leading to performance issues.
Solution: Schedule regular heating maintenance to catch problems early and avoid a headache later. This will help to replace any worn-out parts to avoid further damage.

3. Pilot or Ignition Control Issues

Issue: Problems with the ignition or pilot light can lead to issues with the furnace’s ability to start or stay running.
Solution: Check and clean the pilot assembly. Keep in mind that if you’re uncomfortable or unsure of how to do this, it’s always best to consult a professional HVAC technician.

4. Malfunctioning Thermostat

Issue: Incorrect thermostat settings, a dead battery, or a faulty thermostat can result in temperature control problems.
Solution: Verify thermostat settings, replace batteries if applicable, and consider recalibrating or replacing the thermostat if issues persist.

5. Lack of Maintenance

Issue: Neglecting regular maintenance and inspections can make your furnace prone to breakdowns and poor performance. You could also see increased energy costs as a result of failing to maintain your furnace.
Solution: Schedule annual maintenance. Annual checkups can prevent over 70% of all furnace repairs as well as improve your system’s efficiency by up to 16% — saving you money!
