Top-rated independent heating and cooling across north Georgia and the southern Appalachians
HVAC Repair in Kennesaw, GA — Local Techs, One Call
We fix heating and cooling systems in Kennesaw homes, from a condenser that hums but never cools to a furnace that short cycles on the first cold morning. Call us or send the quote form and tell us what the system is doing. Most HVAC repair in Kennesaw starts with the same handful of causes: a clogged filter, a failed capacitor, a drain line backing up, or a thermostat wired years ago by somebody in a hurry. Kennesaw sits where valley heat pumps meet propane and dual-fuel setups up the ridges, so we ask about your fuel before we quote anything.

HVAC repair in Kennesaw, the local picture
We handle air conditioning repair, heating repair and system replacement for Kennesaw homes, and if your house is uncomfortable right now, call us and we will get you on the schedule. Kennesaw summers run long and humid, so a system that keeps up in May can start falling behind by late July when it is fighting both heat and moisture all day. Winter brings enough hard freezes to matter, especially for heat pumps that lose their defrost control and ice over on a wet January night. Much of the housing here is 1990s and 2000s subdivision construction with the air handler in the attic and ductwork running through that same hot space, plus older ranch homes on crawlspaces where red clay moisture works on the pans and the flex duct. We work on heat pumps, gas furnaces and dual-fuel setups. Before you call, check your thermostat batteries, look for a tripped breaker and change a loaded filter.
Most Kennesaw homes went up during the suburban push of the 1980s through the early 2000s, with brick and vinyl two-story builds on slab or crawlspace. Split systems and gas furnaces dominate, and ductwork run through unconditioned attics or clay crawlspaces is often the reason upstairs rooms never keep up in July.
Day to day we are on I-75, Highway 41, Barrett Parkway and Cobb Parkway.

How soon can you get to my Kennesaw home?
Call us and we will tell you honestly where you sit in the day's schedule. Same-day visits are common in Kennesaw when a system is down, and we tighten arrival windows as the day goes so you are not sitting by the door all afternoon.
Do you work outside Kennesaw city limits?
Yes. We work throughout Cobb, Cherokee and Paulding County homes, including Acworth, Marietta, Woodstock, Dallas and Powder Springs, and we cover work across Georgia and neighbouring states. If you are unsure whether your address falls in our area, give us the road name and we will tell you.
How does pricing work?
Everything gets quoted in writing first, the visit, the parts, the labor, and work starts only when you approve.
What brands can you service?
As an independent company we service every major brand, from Carrier and Trane to Lennox, Goodman and Rheem, gas and electric alike.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form and describe what you hear, smell or feel. Warm air, short cycling, a breaker that keeps tripping. That gives us a head start on the likely cause.
- Step 2
We diagnose on site
A technician checks the thermostat, airflow, electrical connections, refrigerant performance and the outdoor unit. We work the crawlspace and the attic too, because ductwork and drainage cause more trouble than people expect.
- Step 3
You decide, then we fix it
We explain what failed, what it takes to repair it, and what we would watch next season. No work starts until you say go. Most repairs finish the same visit when parts are on the truck.

Why homeowners call us
- Mixed heating is normal to usHeat pumps, propane furnaces and dual-fuel setups all behave differently in cold weather. We know how a heat pump should sound in the thirties and when the backup heat is doing too much of the work.
- We go under the houseRed clay crawlspaces hide crushed ducts, sweating lines and standing water. Comfort problems often start down there, not at the unit, so we look before we start replacing parts you may not need.
- Plain explanationsYou get told what broke and why, in words that make sense. If a repair is a short-term patch on an aging system, we say that out loud so you can plan instead of guessing.
- One crew, six statesWe serve homeowners across Alabama, Georgia, Kentucky, North Carolina, South Carolina and Tennessee. Same approach in every one: show up, diagnose properly, repair what needs repairing, leave the space clean.
- All major brands, gas & electricOne independent crew for Carrier, Trane, Lennox, Goodman, Rheem and more.
- Straight answersNot worth fixing? We say that out loud, and often it saves you the visit fee.
