How Long Do AC Units Last? Central vs. Window

There’s a lot the average homeowner needs to do to ensure that they’re ready to face the heat, and investing in an AC unit is certainly one of the major tasks at hand.

However, one might need to do a little research before deciding on the perfect AC model. After all, this is a multi-year investment. So, it’s prudent to ask: how long do AC units last?

Knowing the average life of an AC unit can help you determine how much to spend and when to replace an AC unit you already have. What do you need to know about AC units and their lifespans? Read on and we’ll walk you through the basics.

How Long Do AC Units Last?

If you’ve already had your current AC unit installed for a few years, you might be considering if this is the year that you toss it and invest in a brand new one. Is it time to move on?

That all will depend and vary based on the brand and model AC unit you bought. Some ACs simply are built of better materials and can be counted on to last. Others, you won’t be so lucky with.

Generally speaking, a window AC unit can last anywhere between 3 and 8 years if properly cared for. That means not overusing it in the summer and storing it properly during the winter months.

Central air systems generally last even longer. They can last up to two decades or more without the need for a full-out repair. When it comes to window vs central air, central air certainly has the benefit of a longer lifespan.

You can learn more about central air maintenance and decide if it might be the right investment choice for you.

When to Replace an AC Unit

If your AC system is getting towards the end of the lifespan we just mentioned, you may be on the fence about getting it replaced. Is it really a necessary expense to take on? You might look for signs that tell you that the AC unit isn’t worth keeping for a whole new season.

The most obvious signs? If the air that comes from your system isn’t as cold or as constant as it once was. AC systems will likely diminish in power before they fully give out, and a system that is giving lackluster results is probably on the way out.

Moisture, leakage, and unusual sounds emanating from the device are also likely signs of deterioration. Invest before you end up without cool air entirely in the middle of a hot summer day.
