How Long Does the Typical A/C Unit Last?

How Long Does the Typical A/C Unit Last

One of the biggest questions people have when they purchase an HVAC unit or buy a home with an existing system is: “How long can I expect this unit to last?” The short answer is, it depends on a variety of different factors, including the amount of use, operational conditions, and maintenance schedule.

Frequency of Use

It should come as no surprise that one of the most important elements that affect the lifespan of an A/C unit, like any appliance, is how often it is used. An A/C unit in a region where frequent use is required on average can last 10 to 15 years, while one that is used less frequently may continue operating for 20 or even 25 years (all other variables held constant).

In order to extend the life of your unit, consider turning the thermostat up a couple of degrees so there is less strain put on the unit. In most cases, this will not result in much impact on your comfort level, but it can have a significant impact on the performance of your system over time.

Cleanliness and Natural Conditions

Another factor in the longevity of your unit is the cleanliness of the system. Dirt and grime build up over time, so it’s best to perform regular cleanings to ensure there is no debris that is affecting performance and could reduce the lifespan of the system.

Extending the unit’s life through preventive maintenance

According to the U.S. Energy Information Administration, only 42% of central air systems receive annual maintenance, yet performing preventive HVAC maintenance is one of the best things you can do to ensure your unit lasts for a long time. HVAC tune-ups are relatively inexpensive, especially when compared to expensive repairs that could have been preventable, or the cost to replace a neglected unit.
