What Is the Lifespan of a Furnace?

The average lifespan of a furnace can be anywhere from 10-20 years. How long your furnace lasts is determined by many different factors. Furnace repair, installation and tune-ups play a big role in that equation answer. A furnace is an important investment, so extending its lifespan is very beneficial. Luckily, we can provide answers on how to upkeep your furnace to increase its longevity.

Proper Installation

The installation of your furnace is where you should start. It is very important to have your system installed by professionals. A proper installation will affect the efficiency, lifespan and performance of your furnace. Improper installation will lead to breakdowns, increased maintenance and a shorter lifespan of your furnace.


To increase your furnace’s lifespan, you should have scheduled, yearly maintenance. It is encouraged to schedule the maintenance in the fall from a licensed HVAC company. Professional furnace maintenance, tune-ups and repair will help increase the number of years your furnace works properly and efficiently. If you properly maintain your furnace, you will decrease the chance of a breakdown.

Furnace Quality

deciding on a furnace system, quality is very important. Contacting a professional HVAC company will help you decide on what unit is right for your home. Paying for a quality system will help avoid repairs and will increase the longevity of your furnace.

Signs You Should Replace

If your furnace is 10-15 years old, you should look into a replacement. In the long run, you could end up saving money instead of having to continually repair the system.
