The Top Signs It's Time to Replace Your AC Unit

Your air conditioning system works hard—especially in Texas. But like all appliances, it won’t last forever. Whether your AC has been limping along or suddenly acting up, knowing when to replace it can save you from unexpected breakdowns and costly emergency repairs.

At Integrity Air Conditioning, we understand how important reliable cooling is for your comfort and peace of mind. If you're unsure whether it’s time to replace your AC unit, here are the top signs to look out for.

1. Your System Is Over 10–15 Years Old

Air conditioners typically last between 10 to 15 years with proper maintenance. If yours is nearing or beyond that range, it may not be worth investing in further repairs. Older units tend to lose efficiency, even with regular service, and could be costing you more in energy bills than necessary.

2. Frequent and Costly Repairs

If you’re calling for repairs every season—or worse, multiple times a year—it may be time to think long-term. Constant breakdowns are not only frustrating but also add up fast. A new AC system is often more cost-effective than sinking more money into an aging unit.

3. Your Energy Bills Keep Rising

An unexpected spike in your energy bill might not just be due to summer heat. Older or struggling units tend to run longer and harder, consuming more energy to cool your space. Upgrading to an energy-efficient model can help lower your monthly costs and improve your home’s overall efficiency.

4. Uneven Cooling Throughout Your Home

If some rooms are hot while others are cold, or your system can’t seem to maintain a consistent temperature, it could be a sign your AC is no longer working effectively. This may be due to worn-out components or poor airflow—and a full replacement might be the smarter solution.

5. Strange Noises or Smells

Odd sounds like grinding, banging, or rattling are red flags. Likewise, musty odors could signal mold or mildew inside the unit. These issues can indicate serious internal problems that may not be worth repairing, especially in older systems.

6. It Still Uses R-22 Refrigerant

If your AC uses outdated R-22 (Freon), replacing it is not just a good idea—it’s a smart one. R-22 has been phased out due to environmental concerns, and it’s becoming increasingly expensive and difficult to source. Newer systems use eco-friendly refrigerants and offer better performance.
