Furnaces are essential in keeping our homes warm and comfortable throughout the cold winter months. However, they are also prone to various issues over time that requires regular maintenance and repairs. Knowing the most common types of repairs can help you better prepare for the unexpected and keep your furnace in top shape for years to come.

Here are three of the most common furnace repairs that every owner should know about:

1. Regular Wear and Tear

Just like any other machine, furnaces can experience wear and tear over time. This may include corrosion, faulty parts, and even clogged filters. To avoid any unexpected breakdowns, it’s important to have a maintenance plan in place so that you can catch any potential problems early on.

2. Gas Leaks

Gas leaks can happen over time, and they can be very dangerous. If you suspect a gas leak, it’s important to contact a professional right away to ensure your family’s safety.

3. Pilot Light and Ignition

The pilot light and ignition system can malfunction over time and require repairs. This can cause your furnace to not work correctly or even shut down completely. If you notice that your furnace is having issues with lighting, it’s essential to have this issue looked at right away.

4. Blocked Air Filters

The filter in your furnace is responsible for trapping dirt, dust, and other contaminants from the air in your home. Over time, the filter can become clogged, which can reduce airflow and cause your furnace to work harder to heat your home. To prevent this from happening, it is important to check and clean or replace your furnace filter regularly. 

5. Thermostat

The thermostat allows you to control the temperature of your home, ensuring that it stays comfortable and energy efficient.

If your thermostat is not working properly, it can cause your furnace to not heat your home correctly. This can cause your energy bills to increase and can also lead to more severe damage to your furnace. If you notice that your thermostat is not working properly, it is important to replace it as soon as possible. 

6. Blower Motor

This repair is necessary when the blower motor is not functioning properly. It can be caused by several factors, including a worn-out motor, a dirty filter, or a clogged air duct. If you’re experiencing issues with your blower motor, it’s important to have it checked out by a professional to ensure it’s functioning correctly.

7. Heat Exchanger Problems

If your heat exchanger is not working correctly, it can cause your furnace to not heat up properly. This is usually caused by a faulty heat exchanger or wiring connection. To fix this, you’ll need to replace the faulty part.

8. Ignition

If your furnace is not igniting correctly, it can cause your furnace to shut off or not heat up properly. This is usually caused by a faulty igniter or a faulty gas valve. To fix this, you’ll need to replace the faulty part.

Final Thoughts

These are the most common types of furnace repairs every owner should be aware of. If you’re having any issues with your furnace, it’s best to call a professional to diagnose and fix them. It’s important to always use caution when working with any electric or gas appliance.
