Nelson straddles the Cherokee and Pickens county line in marble country. Cool Mountain Air brings honest heating and air service to its homes.
Nelson is a small city on the line between Pickens and Cherokee counties. Its original center is in Pickens County, though the city limits have grown south into Cherokee. Incorporated in 1891 and named for early landowner and rifle maker John Nelson, it grew with the railroad and the high-quality marble quarried nearby. Canton Road runs through town toward Tate to the north and Ball Ground to the south. Cool Mountain Air serves Nelson from our base in Adairsville.
We're a family-owned HVAC and plumbing company that has served Northwest Georgia since 1991. Call and you'll talk to Mike Swiger, the owner, who finds the actual problem, explains it in plain English and gives you an up-front price. We repair all makes and models, install Rheem systems with a 100% satisfaction guarantee and handle gas lines and water heaters for homes in town and out in the country.
Nelson's older homes and foothill setting add up to chilly winter nights and humid summers. Houses without ductwork are good candidates for ductless mini-splits or a high-velocity system, and a heat pump needs solid backup heat when temperatures drop. We size every installation with a load calculation and offer 24/7 emergency service. Call Mike at 706-331-0939.
Here's everything Cool Mountain Air offers Nelson homeowners, from furnace repair to ductless systems and plumbing.
Honest AC repair on all makes and models, plus Rheem systems up to 20 SEER sized with a load calculation.
Gas and electric furnace repair and replacement, with gas connections handled in-house.
Heat pump repair and installation, plus ductless mini-splits for additions, garages and problem rooms.
Central air through small, flexible ducts for older homes, a specialty few contractors offer.
Repair, maintenance and replacement for local businesses, with direct access to the owner.
Water heaters, drain cleaning, gas lines and leak repair for homes and businesses.
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."
