If you’ve ever found yourself wondering, how long do AC units last, you’re not alone. With Arkansas summers bringing high heat and humidity, air conditioning is a must-have for any home in Van Buren, Fort Smith, Greenwood, or Alma, AR. At Riverside Comfort Care, we get this question all the time—and the truth is, the answer depends on several key factors.

Generally speaking, most AC units last between 10 to 15 years. However, with proper care and regular maintenance, that lifespan can stretch even longer. In this blog, we’ll cover what affects your AC’s longevity, the warning signs that it might be time for a replacement, and how our expert team can help keep your system running strong.

Understanding the Lifespan of an AC Unit

So, how long do AC units last on average? According to the U.S. Department of Energy, a typical central air conditioner can last 15 to 20 years with proper care. However, that range depends on the type of AC unit you have:

• Central Air Units – 12 to 17 years
• Ductless Mini-Splits – 10 to 15 years
• Window Units – 8 to 10 years

Quality matters too—higher-end models that are properly installed tend to outlast cheaper or poorly installed systems. Your system’s workload also impacts how fast parts wear out. In hot, humid climates like Van Buren, Arkansas, your AC works overtime during the summer months, which can shorten its lifespan if it’s not regularly maintained.

Key Factors That Affect How Long AC Units Last

Several important factors influence how long your air conditioner will hold up. While the average may be 10–15 years, your system’s actual life can vary depending on the following:

1. Frequency of Use

Homes in Van Buren and surrounding areas typically run their AC systems from late spring through early fall. The more often your AC runs, the more wear it experiences. That’s why routine checkups are essential to catching problems early.

2. Maintenance Routine

Nothing shortens the lifespan of an AC unit faster than neglect. Regular maintenance like tune-ups, coil cleanings, and filter changes will improve your system’s performance and longevity. At Riverside Comfort Care, we offer scheduled HVAC maintenance that helps you protect your investment.

3. Installation Quality

Even the best AC unit can fail early if it wasn’t installed correctly. Undersized or oversized systems cause strain, short cycling, and premature breakdowns. Our experts ensure every installation is properly matched and fitted for your home.

4. Climate and Location

Hot, humid summers and high pollen levels in Fort Smith or Greenwood, AR can clog your system’s filters and wear down components faster. That’s why seasonal maintenance is especially important in Arkansas.

5. Filter Changes

A dirty air filter makes your unit work harder, reducing efficiency and causing unnecessary wear. Regularly changing filters—every 1–3 months—is a simple way to protect your system.

Signs Your AC Unit May Be Nearing the End

Even if your AC still runs, it might be on its last leg. Here are some warning signs to watch for:

• Frequent Breakdowns – If you’re calling for AC repairs multiple times a year, your system may be failing.
• Uneven Cooling – Hot spots around the house could mean poor airflow or dying parts.
• High Energy Bills – A struggling AC system often uses more electricity to maintain temperature.
• Loud Noises or Strange Odors – Grinding, rattling, or musty smells shouldn’t be ignored.
• Unit Age – If your system is over 10–12 years old, it might be time to start thinking about replacement.

When in doubt, always call a professional to diagnose your system. Our team at Riverside Comfort Care will give you honest, straightforward answers and help you plan your next steps.
