Factors to Consider

With so many different moving parts, it can be hard to estimate the lifespan of your entire HVAC system. While some parts break down more easily than others, you can expect 12 to 15 solid years from your system as a whole, though its lifespan can depend on several different factors.

Maintenance

Regular tuneups and filter cleaning can help keep your system in top form. Proper maintenance allows all the parts of your heating and cooling system to run smoothly, preventing extra wear and tear. Working proactively to prevent problems down the road can lengthen the lifespan of your HVAC, keeping you and your home happy.

System Size

Every room in your house should feel just right, but it’s easy to go wrong with heating and cooling. If the capacity of your system is a poor fit for your home, you’re probably putting extra pressure on your HVAC system. When components of your HVAC are too small, your unit runs longer to cool and heat your home; too large, and your system is at risk of short cycling.

Environment and Usage

More extreme climates require your HVAC system to work harder to keep your home at a set temperature. If you run your air conditioner and furnace longer and more frequently at full capacity, you can expect this to tire out your system. Leaving windows and doors open can also reduce your HVAC’s heating and cooling ability, forcing it to work harder and wear down more quickly. Consider your environment, how often you use your system, and how hard it has to work when you calculate life expectancy.
