If your AC isn’t cooling like it used to—or if it’s making more noise than usual—you might be wondering: Is it time for a replacement? Knowing how long an air conditioner typically lasts can help you prepare and avoid mid-summer breakdowns.
A central air conditioner usually lasts 10 to 15 years, depending on how well it’s maintained. Window units tend to max out around 10 years. But just like cars, the lifespan depends on how often you use it, your local climate, and how well it’s taken care of
Factors That Affect AC Lifespan
1. How Often Do You Use It
The more your AC runs, the more wear and tear it takes on. Here in the Portland–Vancouver area, we get a seasonal break from extreme heat, so systems can often last a bit longer than in hotter states.
2. Regular Maintenance
Annual tune-ups are key. Simple things like changing the air filter and cleaning the coils can make a huge difference in performance and longevity.
Tip: Schedule professional maintenance every spring to prepare for summer.
3. Weather Conditions
Outdoor units in wet or coastal climates can wear down faster due to moisture and corrosion. Covering your unit in the off-season can help prevent damage.
Signs Your Air Conditioner May Be Nearing the End
Even before it completely stops working, your AC may show warning signs that it’s on its way out. Keep an eye out for:
- Uneven or weak airflow
- Hot spots in the home
- Strange noises or bad smells
- Unit constantly turning on and off
- Leaking or pooling water near the system
- Rising energy bills
- Frequent repairs
If your system is over 10 years old and you’re seeing two or more of these issues, it might be time to consider a replacement.
Why Replacing Your Old AC Is Worth It
Upgrading to a new, energy-efficient unit can mean:
- Lower monthly energy bills
- Improved cooling performance
- Better indoor air quality
- Quieter operation
- Peace of mind during heatwaves
And with today’s smart thermostat options, you’ll have even more control over your comfort and energy usage.
