How Long Do Air Conditioners Last on Average?

Air conditioners are built to thrive through years of consistent use. Note, however, that they’re far from indestructible. At some point, your AC will give in and you will need to replace it. 

“How long do air conditioners last?”, you ask. In truth, it depends on a number of factors. Below, we’re going to discuss those factors in detail, helping you to determine just how far along your AC might be. 

How Long Do Air Conditioners Last?

Some air conditioners give up after 10 years. Some can last as long as 20. However, generally speaking, most air conditioners give up after about 15 years of use. 

Of course, there are a number of factors that dictate just how long an air conditioner will last. As such, every situation is different. But if you’re creeping toward that 15-year mark, you should consider making a change. 

Factors That Dictate AC Lifespan

As we noted, AC life expectancy is dictated by a variety of factors. We’ll discuss those factors in detail below. 

Level of Use

Simply put, the more you use your air conditioner, the faster it will die. After all, the more use an AC sees, the more wear and tear it incurs. And the more wear and tear it incurs, the quicker its components will deteriorate. 

As such, if you’re in a perpetually hot area like southern California, your AC is bound to give in long before an AC that exists in a normally-cold area like Minneapolis, Minnesota. 


Another factor that dictates an AC’s lifespan is maintenance. The more maintenance that you perform on your AC, the more efficiently it will run, and the less wear and tear it will incur over the years. 

If you perform no maintenance on your AC, it’s going to run roughly, becoming less and less efficient as the years pass by. This will — sooner rather than later — lead to a breakdown, one which will require a replacement. 

Surrounding Conditions

Not all AC environments are created equal. Whereas some ACs are attached to immaculately clean houses, others are attached to dirty, dusty, and unkempt houses. Generally speaking, the latter ACs will die before the former ACs. 

For this reason, you need to maintain not only your air conditioner itself but your home as well. Dust and vacuum on a regular basis, and you’ll get the most out of your AC unit.
