How Long Do HVAC Units Last?

If it's been ten or more years since replacing your HVAC unit, you may be wondering: how long do HVAC units last? Learn in this guide.

With the HVAC industry looking to grow by 45 percent in the coming decades, you might want to learn more about how long an HVAC system lasts. Whether you’re looking to avoid those hot summer days or keep yourself warm during the snowy season, there’s a reason why so many people have HVAC units in their homes. But the length of time a unit lasts depends on the quality, size, and usage of the unit.

Here is everything you need to know about how long do HVAC units last.

Average Lifespan

The average lifespan of an AC unit is around 12 to 15 years. Though the exact time on when to replace an HVAC unit depends on other factors. Once it hits the ten-year mark is around the time you can expect it to at least start requiring repairs or acting funky. 

Size of the Unit

The size of the AC unit will play a role in how long your system lasts. The AC maintenance guide of any unit will show the appropriate square footage that the system is meant to support.

If you go too small, you’ll have to work extra hard to cover the entire house. But if you go too big, you’ll run into problems with the system cycling where it turns on and off constantly. Turning off and on places unnecessary wear and tear and causes more harm than if it was constantly running at normal levels.

Usage of the Unit

If you live in extremely hot climates such as Florida, Texas, or Arizona, you’re likely going to need the AC unit running at all times. The more you run your unit, the shorter the lifespan of the unit.

Though you’ll likely be able to expand the lifespan of the unit with regular maintenance and repair. If you’re in need of AC Repair South Florida, then Armstrong Air Inc. has you covered.

Quality of the Unit

Of course, the quality of the unit you go for will play a major on the lifespan of the unit. Going for the cheapest option around may cause you to need to replace your unit in 5 years rather than 15.

Going for a high-quality unit that has automation involved may prolong the life of your unit. Pairing this with a smart thermostat may push the HVAC unit an extra couple of years, though the long-term results are still being studied.

How Long Do HVAC Units Last? Depends on How Much You Use It

So, how long do HVAC units last? While on average, they tend to last around 15 years, there are factors that will increase or decrease the lifespan of the unit. The key is to keep up with the maintenance of the unit and catch problems before they’re bad to ensure your unit doesn’t kick the bucket too early.
