HVAC repair in Marietta, the local picture
We handle air conditioning repair, heating repair and full system replacement for Marietta homes, and if your system is down right now the fastest thing you can do is call us and tell us what it is doing. Marietta summers run hot and sticky well into September, so a system that keeps up on temperature but leaves the house damp is usually a sizing or airflow problem, not a refrigerant one. Then a couple of hard freezes come through in January and we get calls on heat pumps that never come out of defrost. The housing here is mixed. Split-levels and ranches from the 60s and 70s around the older neighborhoods often have undersized returns and ductwork run through a crawlspace with red clay under it. Newer subdivisions off the east side tend to have attic air handlers, which means condensate and drain pan issues in August. We work on all of it, and we tell you what we actually find.
Marietta mixes pre-war homes near the Square with a large share of postwar ranches and brick split-levels, then decades of subdivision building on the east and north sides. Older houses often carry retrofit ductwork in tight crawlspaces or attics, while newer ones run heat pumps or dual-fuel systems with better framing and insulation.
Day to day we are on I-75, Highway 120, Cobb Parkway and Roswell Road.

How soon can you get to my Marietta home?
Call us and we will give you a real window for the same or next day in most cases, depending on how the day is running. Tell us whether you have no cooling, no heat, or a system that runs but will not hold temperature, because that changes how we prioritize the call. If you have already checked the thermostat batteries and the breaker, mention that too. It saves time once we are in the driveway.
Do you cover the towns around Marietta?
Yes. We regularly work in Kennesaw, Smyrna, Acworth, Powder Springs, Austell, Woodstock and the Sandy Springs and Dunwoody side, along with the rest of the region across Georgia and neighboring states. If you are not sure whether your street falls in our route, give us the address and we will tell you straight rather than leaving you waiting on a truck that is not coming.
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.
