About Us

Athens, Georgia

It was 1985. With a thousand dollars and a red pickup, Mack and Linda Chambers began building a heating and air conditioning company with a foundation of family values and hard work. Three decades later, the red pickup is gone, but in its place is a fleet of vans with the distinctive name and brand we’ve become: Clockwork Heating and Air.

Our Customers

  • I picked this company more or less at random from a list of well-reviewed HVAC folks. I was extremely impressed by first, the very personal service and secondly the quality of the installation. It’s a family run business and everyone seems very happy working for them. Our new system is exactly -or better- than described and I would fully recommend these guys.

    Mark Jordan

  • No heat. Called. Came same day. Fixed it within 30 minutes. Very professional. I have heat. I'm happy with service.

    Debbie Finch

  • “We've had a fantastic overall experience with Clockwork…the Clockwork crew was on time, efficient, friendly, and very professional. It was a two day install and they cleaned up after themselves both days, plus they kept their work area tidy while they were working...Would highly recommend Clockwork!”

  • The customer service was amazing! Felt like I was talking with a friend rather than a stranger! Girls in the office were very helpful! Will refer them to others!

    Eric Lamey

  • I've had several positive experiences with Clockwork. They treat me as if I were someone they know and value: my time and specific needs are considered with all service. Since 2016 when my new system was installed, and then in 2017 the house was re-ducted, they have been responsive and conscientious. Go find that anywhere for a residential customer! I have also been fortunate to have them take care of me for after-hours work when I had a heating issue in the winter. Staff on the phone and in person are helpful and willing to answer questions and address any problem I can propose.
