For thousands of years, mankind struggled with hot and cold temperatures. But now, we are masters over the elements. At the flip of a switch, we turn our HVAC on, and the air bows before us. 

The global industry of HVAC systems in 2019 totaled 240 billion dollars. One reason the industry is so popular is that HVAC systems are built to last. 

But they don’t last forever. Many consumers ask, “How long does an HVAC system last?” The answer is a little complicated. 

Once you figure it out, you can preserve your HVAC system for a long time. Here is a quick guide to the HVAC system lifespan. 

What Impacts the HVAC Lifespan

In general, an HVAC system lasts 12 to 17 years. Lifespans vary depending on how it’s used. 

A system that runs continuously will break sooner than a system that doesn’t. Some people don’t realize that their HVAC system is on. Turn off your system during mild days in order to preserve it. 

A system that you don’t maintain will also break sooner. Unfortunately, several things can break an HVAC system. The ignition may not work, or the thermostat may malfunction. 

A repair service can provide replacements and inspections of your system. They can extend the life of it, but only if you practice good maintenance. Switch out your filters when they are clogged and lubricate your motors. 

The location of your home can impact your system. Chemicals in saltwater and sulfur can damage it, decreasing its life expectancy.

Even if your unit is located indoors, it circulates air from outside. Salt can clog your ducts, and chemicals can chip at your motors. 

The Type of HVAC Systems

Some systems last longer than others. On average, a furnace lasts 20 years. Some products can last 30 years with good maintenance and replacements. 

Furnaces are among the oldest HVAC systems, which means that some service providers may have more experience with them. This is one factor in their longer life expectancy. 

Many older homes are built around their furnaces. This is a blessing and a curse. A furnace that fits a home can work for decades, but an improperly fitted furnace can break within a few years. 

Heat pumps can last roughly 16 years. Since they run continuously, they have a lower lifespan. You will need constant maintenance in order to keep your heat pump alive. 

Water heaters can last 10 years. Like heat pumps, their continuous use results in a low life expectancy. Flush out your heater and hire a technician to check it out every year. 

So How Long Does an HVAC System Last?

A home HVAC system is essential to remaining comfortable. But many people have questions when buying one. How long does an HVAC system last? 

Continuous use and chemicals in the air will damage your system. Get it serviced on a regular basis, and keep an eye on parts you can replace. 

A furnace lasts longer than average because maintenance people are more experienced. Older homes also incorporate furnaces into their structures, supporting them. Heat pumps and water heaters last shorter than average because they run so often.
