Due to the lack of resources in the available labor situation, we are having to remove our 24-hour service availability to customers. Once we are able to restate 24-hour service we will change our hours of service back to 24-hour emergency service. We apologize for the inconvenience at this time, but look forward to continually servicing all of our clients with 24-hour service in the near future. Sincerely, Michele Thomas

Are you tired of paying through the nose to heat and cool your home? Does your ac or heat pump pop on and off continuously in an attempt to maintain a consistent temperature? Well, this problem isn’t going to go away anytime soon without intervention. And, with fuel rates constantly increasing, they’re likely to become more pronounced.

Call A-1 Certified Service, Inc. for a no-obligation quote today!

AC Installation

Nothing lasts forever, and that's true for HVAC equipment as well. Even when kept in tip-top shape, your AC unit only has a lifespan of around 15 years. And, even if it's still going strong, old units are inefficient energy guzzlers. Either way, when you decide to replace it, A-1 Certified Service, Inc. is here for you. We've been replacing ACs for 22 years and know how to get the job done. Contact us at (865) 691-5088 to get a free quote on AC installation in Knoxville.

AC Repair

Is your AC unit's rattling keeping you up at night? Or, worse yet, has it stopped cooling completely? Then, you need to call A-1 Certified Service, Inc.. Our HVAC experts will take a look and fix whatever's plaguing the unit. Bad compressor? Busted control board? Fritzy thermostat? It doesn't matter. No matter the problem, we'll quickly diagnose it and fix your broken air conditioner. Contact us by phone or form to schedule your AC repair in the Oak Ridge or Farragut areas.

AC Maintenance

Knoxville really puts your AC through the wringer. And, like you, it sometimes needs some TLC. That's why we offer comprehensive AC maintenance services. Not only will an annual tune-up help your unit last longer and go farther, but it will also help keep your energy bills low. Furthermore, it'll allow you to spot potential failure points in the offseason—not during a 100-degree heat wave. For more information on our HVAC maintenance plans, give us a call!
