Is Your Air Conditioner on Its Last Leg? Signs It’s Time to Replace Before It Fails
When the summer heat cranks up in the Triad, the last thing you want is for your air conditioner to throw in the towel. At Gwyn Services, we’ve seen it happen time and time again: a tired, overworked AC system finally gives out—usually during the hottest week of the year.
Before you're left sweating and scrambling for emergency repairs, here are some clear signs your air conditioner might be nearing the end of its life—and why now might be the right time to replace it.
1. It’s More Than 10–15 Years Old
Most air conditioners have a lifespan of around 10 to 15 years, depending on how well they’ve been maintained. If your unit is creeping up in age—and especially if it uses outdated R-22 refrigerant (which is no longer manufactured)—it’s probably time to consider an upgrade.
Newer models are far more energy-efficient, which means lower utility bills and better performance.
2. Frequent Repairs Are Adding Up
If you’ve called in more than one repair technician over the past couple of summers, those service costs can start to outweigh the value of keeping your old system running. Constant repairs are a red flag that key components are wearing out—and it’s only a matter of time before something major fails.
Tip: If a repair is more than 30–40% the cost of a new unit, replacement is often the smarter investment.
3. Your Home Isn’t Comfortable Anymore
Are some rooms too hot while others feel like a freezer? Does your system seem to run constantly without ever quite catching up? These are signs your AC is losing efficiency—or it may not have been sized correctly in the first place. Inconsistent comfort is more than a nuisance—it could signal a system on the verge of failure.
4. Your Energy Bills Keep Rising
If your power bill seems to rise every summer without a clear reason, your aging AC system could be the culprit. Older units work harder (and longer) to keep your home cool, which uses more energy and puts strain on your wallet. An ENERGY STAR®-rated system can cut your cooling costs significantly—and perform better while doing it.
5. Strange Noises, Smells, or Leaks
Unusual sounds like grinding, rattling, or buzzing can indicate worn-out parts or failing components. Musty smells may mean mold in the ductwork, and any visible leaks could be refrigerant or condensate line issues—both of which can signal serious internal problems.
Bottom line: If your AC is acting or smelling “off,” don’t ignore it.
