One of the concerns of homeowners when they are purchasing a new furnace or deciding whether or not to replace their present unit is, “what is the expected life span of a furnace”? This is a nice question, but how long is a furnace supposed to last depend on a number of factors. In this blog post, we are going to talk about the average life span of a furnace and what are the signs that suggest that your furnace is dying.
The expected life span of a furnace has a direct relation to how well it is maintained, whether or not it was installed properly and how often it is used. Generally, you can expect a properly installed and well maintained furnace to last around 15-20 years. But, if your furnace is not maintained properly and or it wasn’t installed in a right manner, its life expectancy can decrease by a several years.
Having a furnace go out of service unexpectedly is one of the very nerve-racking experiences a homeowner faces. Thankfully, furnaces give some warming signs of when they can go out of service, and these signs are very obvious and evident to anyone in the home- you just need to what to look for. By looking for these signs, you can be ready for a furnace replacement or repair when it is the time. Additionally, you can avoid health risks that you can face from using an old furnace.
