From downtown Wall Street to the businesses along I-75, Cool Mountain Air brings owner-led heating, cooling and plumbing service to Calhoun and all of Gordon County.
Calhoun has been the seat of Gordon County since 1851, when the town grew up along the Western & Atlantic Railroad beside the Oostanaula River. U.S. 41 still runs through downtown as Wall Street, past historic Oakleigh, the Harris Arts Center and its Roland Hayes Museum. Just outside town, the New Echota Historic Site marks the former capital of the Cherokee Nation. Cool Mountain Air serves Calhoun from our base just down I-75 in Adairsville, and we've been taking care of Gordon County homes and businesses since 1991.
Calhoun's neighborhoods tell the story of a town that has rebuilt and grown more than once. Older homes near downtown can be tough to fit with standard ductwork, so we install high-velocity small-duct systems and ductless mini-splits that keep plaster and trim intact. In the newer subdivisions spreading toward the interstate, we start every replacement with a load calculation so the system is sized for the house, not guessed at.
Calhoun is a working town. Carpet and flooring manufacturing has anchored the local economy for generations, and the stores, restaurants, offices and shops around the I-75 exits and the outlet center keep customers coming through every day. Our commercial HVAC service covers repair, maintenance and replacement for businesses that can't afford to close their doors when the heat or air quits.
Gordon County summers are long and sticky, and the river valley holds humidity that makes an undersized or poorly maintained air conditioner struggle. Winter cold snaps then turn the job over to furnaces and heat pumps, and spring brings a heavy coat of pollen. Regular seasonal maintenance keeps coils clean, airflow strong and small problems from becoming breakdowns.
When you call Cool Mountain Air, Mike Swiger, the owner, answers. He finds the real problem, explains it in plain English and gives you an up-front price before any work starts. Our technicians are licensed, background-checked and drug-free, and we're a Rheem Authorized Dealer with a 100% satisfaction guarantee on installations. We also offer 24/7 emergency service and plumbing. Call Mike at 706-331-0939 for Calhoun heating and air done right.

Our customers keep pointing to the same things: honest answers, fair prices and work done right. Here's what a few of them have to say about Cool Mountain Air.
"Mike Swiger is an expert HVAC engineer. I hired him to install a smart thermostat but during installation, he found a completely different issue with my HVAC and fixed it for a very reasonable rate. It was scary because I had not even lived in this house for a month and was worried that I would have to get a whole new system. He's very knowledgeable and explains everything going on with the system and how he fixed it in a way that I could easily understand. I highly recommend Cool Mountain Air to anyone for their heating and cooling needs for their home."
