Kennesaw’s HVAC work splits into two very different jobs: nursing 1980s and 90s systems through one more Georgia summer in neighborhoods like Legacy Park, or correcting builder-grade installs in newer subdivisions around Kennesaw State University. The climate here doesn’t give your equipment a break, with 90-degree humidity from June through September and damp, chilly winters that push heat pumps hard. We’re Dalton Heating & Air, a Garrison Partners company, and we work on both ends of that spectrum every week. Call (478) 400-5908 when your system stops holding temperature.
Why Kennesaw Homes Are Different
Kennesaw grew fast starting in the late 1980s, and the housing stock tells that story block by block. Large planned communities like Legacy Park and Cedar Crest went up with brick and hardiplank exteriors, slab foundations, and attic-mounted air handlers. Those attic installs run hot in summer, which shortens blower motor life and makes every repair a crawl through 130-degree heat. Older homes near downtown Kennesaw, some dating to the 1950s and 70s, often still have original ductwork and electrical panels that were sized for a window unit, not a modern central system.
The humid subtropical climate adds another layer. Slab-on-grade homes trap moisture, and an oversized AC that short-cycles won’t pull humidity out of the air. We see condensers clogged with spring pollen and fall leaves across Kennesaw every year, and the fix is usually a thorough coil cleaning paired with a check on refrigerant charge, not a parts swap. Homes near KSU tend to be newer, but we regularly find undersized ductwork from the original builder install that leaves upstairs rooms eight degrees warmer than the rest of the house.
Styles & brands we work with







Our Main Kennesaw Services
Kennesaw homeowners call us most for two things: getting a failing AC back online before the humidity becomes unbearable, and replacing aging heat pumps and furnaces before they quit in the worst possible weather. Here’s what each job looks like in Kennesaw specifically.
AC Repair in Kennesaw
Most AC Repair in Kennesaw calls start the same way: the thermostat reads 78 but the air coming out of the vents is lukewarm, or the outdoor unit is running constantly and the house won’t drop below 80. On slab-foundation homes in neighborhoods like Legacy Park, we frequently find capacitor failures, contactor burnout, and refrigerant leaks at the evaporator coil. Older R-22 systems present a harder call, because a recharge on obsolete refrigerant can run into the hundreds while the system itself is nearing the end of its service life. We put the numbers in writing before touching anything, so you decide with the full picture.

Heat Pump Installation in Kennesaw
A Heat Pump Installation in Kennesaw has to handle both ends of Georgia’s climate: 95-degree summer afternoons and 30-degree winter nights when the auxiliary heat kicks in. The newer subdivisions around Kennesaw State are full of heat pumps, and a lot of them were installed with ducts that can’t move enough air for the square footage. That’s why we run a load calculation on every install rather than swapping in the same-sized unit that was there before. If the ductwork is the bottleneck, we tell you before you spend on a larger system.

Furnace Repair in Kennesaw
Furnace Repair in Kennesaw tends to cluster in late January and February, when a gas furnace that ran fine all fall suddenly won’t ignite on a 25-degree morning. Older homes near downtown Kennesaw often have furnaces that predate the current electrical code, which means we’re checking flame sensors, ignitors, and control boards on units that may have original wiring. The damp winter air also contributes to rusted burners and blocked condensate lines on high-efficiency furnaces. A written diagnosis comes with every call, and the repair price is fixed before we start.
