Below the summit that gives west Cobb's Lost Mountain area its name, Cool Mountain Air installs and services heating and cooling systems sized right for larger homes.
Lost Mountain is an unincorporated community in west Cobb County, named for the peak that rises above it. In June 1864, the summit anchored one end of a Confederate defensive line during the Atlanta Campaign. Today the Lost Mountain Store, open since 1881 at Dallas Highway and Mars Hill Road, still marks the crossroads, and Lost Mountain Park offers trails and a pond. Cool Mountain Air serves Lost Mountain from our base in Adairsville, as we have served the region since 1991.
Many homes here are larger, two-story houses on generous lots, and a single system often can't keep both floors even. We start every installation with a load calculation and install Rheem systems up to 20 SEER, along with heat pumps and gas furnaces with connections handled in-house. You talk to Mike Swiger, the owner, from the first call.
Lost Mountain sits higher than much of the county, and winter nights can turn cold, so dependable backup heat matters. Summers are still hot and humid. Mike quotes an up-front price before work starts, and we offer 24/7 emergency service. Call Mike at 706-331-0939.

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."
