Reasons For A Broken or Underperforming Furnace

Have you ever experienced waking up in the middle of a cold night and realizing that your furnace is not functioning properly or, worst, it completely stopped working? The thought of having to go through the night without heat can be extremely daunting, especially during the winter season. If you own a home, you know that it's important to keep your furnace in good condition to avoid these situations. In this blog post, we will discuss the most common reasons why furnaces break down or underperform to help you avoid potential problems and keep your family warm during the cold season.

1. Age of the Furnace

One of the most common reasons why furnaces break down is due to the age of the unit. Generally, a furnace that is more than 15 years old becomes less efficient and more prone to breakdowns. If your furnace is nearing its maximum age, it might be time to consider a replacement. A new furnace can save you money in the long run since it will be more energy efficient and reduce the risk of unexpected breakdowns.

2. Dirty Filters

Dirty filters in your furnace can cause several issues. Clogged filters can reduce airflow, forcing the furnace to work harder and increasing your energy bills. Additionally, dirty filters can overheat the system, leading to frequent breakdowns. Make sure to replace or clean your furnace filters regularly to keep your furnace running smoothly.

3. Ignition or Pilot Issues

A malfunctioning ignition or pilot light can cause your furnace to stop working or, in some cases, release dangerous fumes. If you notice that your pilot light is constantly flickering or the flame is yellow instead of blue, it might be time to call an HVAC technician to take a look at your furnace.

4. Thermostat Malfunctions

A malfunctioning thermostat can cause several issues with your furnace. Your furnace might not turn on at the set temperature or it might cycle on and off frequently. It's important to have your thermostat checked regularly to keep it in working order.

5. Lack of Maintenance

Lastly, lack of maintenance can cause your furnace to break down or underperform. Regular maintenance includes cleaning, checking for leaks, and lubricating moving parts in the furnace. Scheduling annual maintenance will help you avoid potential breakdowns and ensure your furnace operates efficiently.



It's important to address any issue with your furnace immediately to avoid costly repairs or potential safety hazards. Keep in mind that proper maintenance is the key to keeping your furnace running smoothly. However, if you're experiencing issues with your furnace, enlist the help of a professional HVAC technician to ensure that your furnace is fixed correctly and efficiently.
