How Long Do AC Units Last In Schertz, Texas?

by | Apr 6, 2023 | AC Maintenance

Summers are hot in Schertz. 

You could head down to the Schertz Aquatic Center or Pickrell Park for a dip in the pool, but that only offers so much relief.

You want an AC system that’s built to last for the hottest days.

In this article, we’re going to teach you how long AC systems typically last—and what you can do to make them last longer. 

How long does an air conditioner last?

There are a number of factors that affect the longevity of your unit, from ensuring proper installation for your new AC unit to regular maintenance of your AC’s components. 

The type of system

There are many different types of AC systems and the one you choose can have a dramatic influence on the longevity of your air conditioner. Here are a few examples:

  • A window air conditioner is less energy efficient than a central air conditioner. This leads to greater wear and tear. Window air conditioners tend to last for about 8 to 10 years.
  • Heat pumps, which act as AC units during the summer, generally last about 15 years—but they have the advantage of acting as a heating source during the winter.
  • High-efficiency central air conditioning units generally last for 15-20 years, depending on frequency of use.
  • Ductless mini-split systems are estimated to last up to 30 years—but we have a little less data on them as they’re relatively new.

As you can see, the type of air conditioner you buy in Schertz can dramatically affect its lifespan. Next, let’s look at how usage can affect your AC’s lifespan.

Frequency of use

This should come as no surprise—the more often you use your air conditioner, the shorter its service life will be.

Here in Schertz, you’re going to want to use your air conditioner all summer long. In fact, using your AC almost year round isn’t that unlikely—many Schertz residents will use their AC nine months of the year or more.

That means you can expect your air conditioner to have a shorter life expectancy than it would in, say, central Canada. You can mitigate the wear and tear caused by frequency of use, though, by limiting how much your air conditioner needs to cool your home. Increasing the temperature by a couple degrees can increase your AC’s life span. 


Another fact when it comes to improving the service life of your air conditioner: Regular maintenance will improve your unit’s life span.

Routine maintenance will reduce wear and tear and improve the energy efficiency of your air conditioning unit. When properly maintained, your air conditioner will have a long service life—much longer than a unit that isn’t regularly cleaned and tuned up.

Air conditioning maintenance can also improve cooling and air quality. 

In the long run, AC maintenance in this part of Texas usually pays for itself—you’ll dramatically increase the lifespan of your unit, and the higher energy efficiency of your unit will save you money. 

Age of the unit

The older your unit is, the sooner it’s going to break down.

This seems obvious, but there are more reasons for it than you might think. Older units, even if they’ve never been used, are simply less efficient than newer models. They need more maintenance, and even when that maintenance is done, they’ll have a shorter life span.

That’s one of the reasons we always recommend buying a new air conditioner—never buy a used air conditioning unit.

Keep Your AC Filter Clean

A clogged filter makes your AC work harder and reduces efficiency. Check filters monthly and replace them when needed. Learn how to properly clean your AC filter to maintain airflow, improve performance and extend the life of your HVAC system.
