Hiram grew fast, and a lot of the heating and cooling equipment that came with that growth is reaching the end of its life. Cool Mountain Air helps Hiram homeowners repair or replace it the right way.
Hiram was incorporated by the Georgia General Assembly in 1891 and named for Hiram Baggett, its first postmaster. For most of its history it was a small Paulding County crossroads. Then metro Atlanta arrived, and the town more than doubled in size during the 2000s. U.S. 278 and Georgia 92 meet in the middle of town, and the Silver Comet Trail passes through, with a trailhead next to Homer Leggett Park where an old caboose sits in the parking lot. Cool Mountain Air serves Hiram from our base in Adairsville, bringing family-owned heating and cooling service to the area since 1991.
Many Hiram homes were built during that growth spurt, and the air conditioners and furnaces installed then are now getting old. If yours is breaking down more often or struggling to keep up, it may be time to talk about replacement. We start every install with a load calculation and put in Rheem systems up to 20 SEER, sized for your home. If a repair makes more sense, Mike will tell you so. We work on all makes and models.
The U.S. 278 and Georgia 92 corridors are lined with retail stores, restaurants, medical offices and service businesses, and none of them can afford to lose cooling on a summer afternoon. We provide commercial HVAC repair, maintenance and replacement for Hiram businesses, with the owner on the line when you call.
Hot, humid summers in Paulding County push air conditioners for months, and winter cold snaps put furnaces and heat pumps to the test. Spring pollen clogs filters and coils just as cooling season gets going. Regular seasonal maintenance keeps older equipment running and helps newer equipment last.
Mike Swiger owns Cool Mountain Air and takes the calls himself. He finds the real problem, explains it in plain English and gives you an up-front price before work begins. Every technician is licensed, background-checked and drug-free, and the tough problems other companies give up on are our specialty. We're available 24/7 for emergencies and handle water heaters, drains, gas lines and leaks. Call Mike at 706-331-0939 for heating and air service in Hiram.

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."
