AC Repair vs. Replacement: Which Is Right for You?

It’s not always easy to tell when an air conditioning system should be repaired or when replacement is the best option. While you may believe that replacing your AC is the more costly option, it could actually save you money in the long-run. That being said, our highly trained, NATE-certified technicians are fully capable of repairing most AC issues on all makes and models from the industry’s leading brands.

We can help you out if you’re experiencing any of the following AC issues:

  • Lack of cool air
  • Weak airflow
  • Uneven cooling
  • Thermostat issues
  • Unpleasant odors
  • Freon leaks
  • Unusual noises
  • Increased energy bills
  • Poor energy efficiency
  • Insufficient cooing

It’s possible that your AC is simply getting old and no longer works as well as it once did. It’s also possible that it was installed incorrectly or that poor AC maintenance led to problems that no require repair or full system replacement. No matter the issue, our technicians will provide a quick and accurate diagnose, then get right to work making the necessary repairs.
