Is It Time to Replace Your Old AC? 5 Signs to Watch For
When the summer heat rolls into Connecticut, the last thing you want is to be stuck with an AC system that can’t keep up. While some issues can be fixed with a quick repair, there comes a point when replacing your old system makes more financial and functional sense.
If you’re unsure whether your air conditioner is ready for retirement, here are five signs it may be time for a replacement—and how Accurate Cooling & Heating can help.
1. Your System Is 10-15+ Years Old
Most air conditioners have a lifespan of around 10 to 15 years—especially if they’ve been well maintained. But as they age, efficiency drops, and repairs become more frequent. If your system is pushing (or past) that range, it may be time to consider a high-efficiency replacement.
2. Repairs Are Becoming Routine—and Costly
If you're calling for service every summer (or even multiple times a season), the costs can add up fast. A good rule of thumb: If a repair costs more than 50% of the price of a new unit, you're likely better off upgrading.
3. Uneven Cooling or Weak Airflow
Notice hot spots in certain rooms or low airflow from vents? This could mean your system’s blower is failing or the unit simply isn’t sized or operating properly anymore. Newer systems—especially ductless mini splits—offer precise zone control and consistent comfort.
4. Your Energy Bills Keep Rising
Older systems tend to lose efficiency over time, even with regular maintenance. If your summer utility bills have been creeping up year after year, your AC could be the culprit. Upgrading to a modern ENERGY STAR® rated unit can deliver big savings long-term.
5. Strange Noises or Odors
Grinding, squealing, rattling, or musty smells are all red flags. These can signal worn-out components, failing motors, or mold growth inside the system—none of which should be ignored.
