Call (229) 514-0545 and we’ll start with a free load calculation, not a sales pitch.
Our AC Installation team knows what Marietta homes throw at them: red clay dust, tight crawlspaces, undersized return air, and attics that hit 130°F by July. We’ve been handling this specific set of problems since 2004, and we’re the crew other HVAC companies refer the hard ones to.

Andre Fuller, who leads our Marietta team, has walked more crawlspaces in this city than most HVAC owners have in their entire careers. He’s the one who noticed that east Marietta’s red clay was cracking rigid ductboard in slab-on-grade ranches years before it became a known local problem. That kind of ground-level knowledge is what you get when you call us.
Styles & brands we work with
Heat Pump Installation in Marietta
Heat pump installation in Marietta is a smart choice for homes that don’t have natural gas service, especially in the rural pockets east and west of the city where propane tanks and electric resistance heat are the only other options. A heat pump heats and cools from one outdoor unit, which means fewer systems to maintain and lower year-round energy use. For most Marietta homes, we size heat pumps at 2 to 5 tons and install them for $3,500 to $7,500, depending on the unit’s efficiency, your ductwork, and any electrical panel upgrades.
Why Rural Marietta Properties Choose Heat Pumps
Homes off Macland Road, Dallas Highway, and the county roads outside the city limits often sit on large lots with no gas main anywhere nearby. Running a gas line isn’t an option, and heating with propane means watching tank levels and paying delivery markups. A cold-climate heat pump eliminates that entirely. It’s electric, efficient, and one system handles the whole year.
What We Check Before Installing a Heat Pump Here
Before we quote a heat pump for a Marietta home, we measure the actual heating and cooling load, not just swap the old unit size. Many 1970s and 80s ranches in this area were built with 6-inch round ducts that can’t move the air a modern heat pump wants to push. We’ll check static pressure, return air capacity, and the condition of your duct connections under the house before we recommend a size.
Ductless Mini Split Installation in Marietta
Ductless mini split installation in Marietta solves the room-by-room comfort problem that ducted systems can’t fix without tearing out walls. Think converted garages, sunrooms off the back of a brick ranch near Kennesaw Mountain, finished basements, or home offices over a hot east Cobb garage. A ductless system gives you independent temperature control per room, and for most homes we install them for $3,500 to $7,500, depending on the number of indoor heads and outdoor capacity.
For Workshops and Outbuildings
If you run a woodshop, home gym, or studio in a detached building near the Marietta Square, running ductwork from your main system rarely makes sense. The distance, the insulation, the air loss through buried flexible duct: it’s a losing proposition. A single-zone mini split gets that space comfortable on its own thermostat, without touching your main HVAC.
When Ductwork Is the Problem, Not the Unit
We see this constantly in east Marietta: the rooms furthest from the air handler stay hot no matter what the thermostat says. That’s usually a duct problem, not an equipment problem. Rather than rip out finished ceilings, we’ll often install a ductless head in the problem room and let it run independently. It’s faster, cheaper than a full duct replacement, and the room finally gets cold.
Trusted Brands We Service in Marietta
We install and service Trane, Lennox, Goodman, and Rheem equipment, and we’re certified to work on those systems-including Trane repair in Marietta-without voiding your factory warranty. That matters in Marietta, where summers are brutal and a 10-year parts warranty is worth real money. Because we keep common components and supplies stocked locally for our Marietta routes, we can often get parts the same day rather than making you wait on a distributor shipment. When you call us for an AC install or repair, you’re not getting whatever brand the supply house had on sale that week. You’re getting a system sized and matched to your home, backed by a brand that has parts available when things go wrong.

AfterCommon AC Installation Problems We See in Marietta Homes
- Undersized return air in east Cobb tract homes. Many 1980s and 90s split-levels and ranches were built with one central return in the hallway. That starves the blower, dries out the coil, and leaves back bedrooms hot. We often add return ducting before we install the new unit.
- Ductwork damaged by red clay soil movement. Marietta’s clay-heavy soil expands and contracts with moisture, shifting slab foundations just enough to crack rigid ductboard and pull flex duct connections loose. A new AC on top of leaking ducts will never cool right.
- Oversized condensers on tight 1970s ranches. A 4-ton unit on 1960s ductwork doesn’t cool better: it short-cycles, spikes static pressure, and dies young. We size to the house’s actual load and the ducts’ actual capacity, not the square footage alone.
- Uninsulated line sets through blazing attics. Running copper refrigerant lines through an unshaded east Marietta attic without proper insulation means the cold refrigerant picks up heat before it even gets to the evaporator coil. It’s a rookie mistake we fix on a lot of DIY and low-bid installs.

FAQs About AC Installation in Marietta
Because east Marietta’s red clay soil shifts foundations, which cracks rigid ductwork and pulls connections loose, forcing your system to work against leaks and high static pressure for years before it finally gives out. Add in the fact that many east Cobb homes run AC from April through October, and a 12-year lifespan under those conditions isn’t unusual. The fix is a properly sized install with sealed ducts, which is what we measure for on every quote. Call (229) 514-0545 and we’ll assess your system’s actual condition, not its age sticker.
Yes, and for many rural Marietta properties without a gas main, a heat pump is the best option you have. It heats down to single-digit outdoor temperatures, runs entirely on electricity, and eliminates propane tank monitoring. We size cold-climate heat pumps for Marietta’s actual winter lows and your home’s specific envelope, not a generic Southeast formula. It costs $3,500 to $7,500 installed, and we can help with any utility rebates available for the efficiency level you choose.
For a detached workshop, garage, or studio, a ductless mini split is usually the most practical cooling and heating option you can install without major construction. You get independent temperature control, a quiet outdoor unit, and no need to tear into finished walls or run ductwork across a yard. Most single-zone installs in the Marietta area run $3,500 to $7,500, and we’ll give you a written price before ordering anything. Call (229) 514-0545 and we’ll do a free sizing walkthrough of your space.
In Marietta this usually comes down to two things: insufficient return air and duct leaks caused by the red clay foundation shifts we see all over the city. The front of the house gets the coldest air because it’s closest to the blower and has the return register pulling air back. The back bedrooms are at the end of the duct run, and if that duct is cracked or disconnected in the crawlspace, they’re getting a trickle instead of a stream. We diagnose this with a static pressure test and a visual crawlspace inspection, then fix the actual leak or add return air where it’s missing.
SEER2 is the newer, stricter testing standard that replaced SEER in 2023, and it reflects real-world performance more accurately than the old rating did. A 15 SEER2 unit performs similarly to what used to be called a 16 SEER under the old test. For Marietta’s long cooling season, higher SEER2 means lower summer electric bills, so it’s worth paying attention to, but don’t obsess over one point. We’ll show you the payback difference in dollars for each efficiency level we quote you. Call (229) 514-0545 and we’ll price out a few options.
If your AC is done, limping, or just too old to trust through another Cobb County summer, call us today. We’ll size it right, price it in writing, install it clean, and stand behind it for a full year. (229) 514-0545.
