How Long Do Furnaces Last?

How Long Does A Furnace Last On Average

Furnaces are popular appliances used for heating air or water and circulate it in a heating system, throughout a building. They are fired by gas or oil.

When you consider installing such an appliance, one of the most common questions is how long it will last. A very legit question, considering the investment… The average lifespan of a furnace is up to 20 years, although it may vary significantly. There are people who claim to have 30-year old furnaces that still work great and, if this is true, they are lucky. However, there is no guarantee that your furnace will also last that much. Actually, after 15-16 years of use, you should be prepared to replace it, as the signs of age are likely to appear soon. Besides, an old furnace may work, but it does not mean that it is also efficient; it will likely use more fuel and energy.

When you replace your furnace, make sure that you install a new one sized adequately for your house, as this is an important factor that influences its efficiency.  Do some research on some of the Denver HVAC sites to determine what furnace will work for you.

There are different models of furnaces and they may reach old age differently – some better than others. To increase their lifespan, contact a professional technician and schedule a regular tune-up, once a year.
