A 15-year-old air conditioner might still be running, but that doesn’t mean it’s doing your home—or your energy bills—any favors. Most units lose efficiency over time, and even regular AC maintenance can only go so far after a decade and a half of service.
How Long Do Air Conditioners Typically Last?
Most air conditioners have a lifespan of 12 to 17 years, depending on the brand, usage, and how well they’ve been maintained. Hitting the 15-year mark is a clear sign it’s time to start evaluating whether your system is still worth keeping or if it’s time to move on.
Signs Your AC Might Be Ready for Replacement
If your air conditioner is showing one or more of these signs, an AC replacement might be the smarter choice:
- Frequent repairs or breakdowns
- Inconsistent cooling or hot spots in your home
- Rising energy bills with no clear explanation
- Strange noises or excessive humidity indoors
- R-22 refrigerant (now phased out and expensive to replace)
Even if your unit still works, it’s likely running far less efficiently than newer models. That inefficiency can cost you month after month.
Benefits of Upgrading to a New System
Today’s air conditioners are designed to deliver more cooling with less energy. Upgrading can offer:
- Improved energy efficiency and lower monthly bills
- Quieter operation and better indoor comfort
- Modern features like smart thermostats and zoning capabilities
- Stronger warranties and peace of mind
A new unit doesn’t just cool better—it often pays off in long-term savings.

If your air conditioner is 15 years old, it’s better to plan for a replacement than be caught off guard during a heatwave. The cost of an emergency repair or rushed install can be higher than a well-planned replacement done on your timeline.
