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.

  • 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

  • This is by far the best service I have ever received and I'm in the sales and service industry! They explained and showed me what was going on with my system, gave me options AND most important- peace of mind. I highly recommend getting a Club Membership, its two seasonal check-up visits a year BEFORE there is ever a sudden problem. A++

  • 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!”
