Got what we paid for. Adam and the team installed a new variable-speed AC and the upstairs is finally comfortable.

About
Hello — I'm Adam, founder of Old Meridian Heating & Cooling. We've been quietly building a reputation around Hamilton County for 23 years. I personally walk every job before we start so the homeowner knows exactly what to expect. About 70% of our work comes from neighbors recommending us, and that's how we like it. Looking forward to meeting you. Demo listing

Pretty frustrating from start to finish. Adam and the crew tuned up our system in October and it ran flawlessly all winter.

We are so glad we found Adam and the team. Adam and they replaced our 20-year-old furnace right before a deep freeze.

Could not ask for better. Adam and they replaced a cracked heat exchanger and explained exactly why it failed.

Really pleased with the result. Adam and they redid our return air ducts and the difference in airflow is night and day.

It was okay — got the job done. Adam replaced our 20-year-old furnace right before a deep freeze, and the whole crew left the worksite cleaner than they found it. They also offered three different options at three different price points, which we really appreciated. We'd probably try them again, but get a couple other quotes first.

Absolutely the best experience we've had with a contractor. Adam installed a new variable-speed AC and the upstairs is finally comfortable, and the whole crew wore booties in the house without being asked. They also left the worksite cleaner than they found it, which we really appreciated. Saved their number to favorites.

Quality work, fair price. Adam and they set up a whole-home humidifier and we finally don't get nosebleeds in winter, and they sent us photos of the progress while we were at work. Glad we picked them.

Great experience with one tiny nitpick. Adam and they redid our return air ducts and the difference in airflow is night and day.

Dependable and easy to work with. Adam and they installed a new variable-speed AC and the upstairs is finally comfortable, and they called the night before to confirm. Highly recommend with one minor caveat — but no big deal.

Great experience with one tiny nitpick. Adam and they diagnosed a ductwork airflow issue that previous companies just sold us on a new unit for.

We're customers for life now. Adam installed a Mitsubishi mini-split in our bonus room above the garage, and the whole crew took the time to answer every question we had. They also had a clearly labeled truck and uniformed crew, which we really appreciated. We've already recommended Adam to two neighbors.
