3 Ways to Know it’s Time for a Furnace Replacement

February 17th, 2016 by THS

An old gas furnace in a dirty basement, it's time for a furnace replacement.
From strange noises to sub-par heat output, there are many red flags that can signal your furnace is at death’s door. No one wants to think about having to replace their furnace, especially when it decides to die in the middle of winter. However, the reality is, the average furnace lasts between 15 and 20 years, according to This Old House. Perhaps you’ve gotten lucky and were rewarded with two full decades of service from your furnace because you were diligent about keeping up with regular maintenance. Even so, furnaces have a set life span and eventually you will need a replacement.

Aside from old age, here are three signs your furnace needs to be replaced.

1. Strange Noises

If you’re hearing clanking, clicking, or other weird noises coming from the unit that weren’t there before, this could be a sign of impending furnace replacement. Of course, all furnaces have their unique sounds that we as homeowners have come to get used to, but anything that sounds out of the ordinary should be checked. These noises could indicate a problem with any of the following:
• Slow or worn motor belt
• Dirty gas burners or pilot light adjustments
• Leaks
• Blower motor bearings that need to be lubricated
• Cracked heat exchanger
Any one of these problems can be fixed, so they don’t always indicate a failing unit. However, if you keep experiencing these issues and getting them fixed, coupled with an aging furnace, you may need to replace the whole unit. Only your professional heating service professional can know for sure after a thorough inspection. That’s why you should call us at Thornton Heating Service.

2. Rising Energy Bills

Have you been noticing your heating bills creeping up month after month? This could signal a lack of efficiency in your existing unit, making your unit work harder than necessary to obtain an optimal comfort level. This could be a maintenance issue or it could mean your furnace is on its way out. As the years go on, your furnace naturally loses its efficiency, especially if you haven’t been keeping up with yearly maintenance tasks. You could end up spending way more on repairs and maintenance for an inefficient furnace than if you had just bought a whole new one. In general, most furnace breakdowns occur during the unit’s last two years of life, so if you’ve been shelling out $200 here and there to get various parts fixed, you’re better off purchasing a new energy-efficient unit and saving yourself the hassle.

3. Uneven Heat Distribution

This is a common problem with aging furnaces. If some rooms in the home are getting heat while others aren’t, or you’re noticing subtle variations in comfort level room to room, your furnace could be breaking down. When this happens, uneven airflow can detract from your heating system’s effectiveness, leaving your house insufficiently heated. This could even do lasting damage to your entire HVAC system if you don’t do something about it.
