A new air conditioning system for a Johns Creek home typically runs $3,500 – $7,500, and the installation itself takes one to three days depending on the home’s size, zoning, and ductwork condition. That price includes a written quote before any work starts, so you know exactly what you’re paying before a single tool comes off the truck. We serve every neighborhood in Johns Creek from Country Club of the South to St Ives to Medlock Bridge, and a live person answers when you call (478) 606-5046, day or night.
What sets Johns Creek apart from most Atlanta suburbs is the housing stock. You’re not dealing with tight 1,500-square-foot ranches here. You’re cooling 4,000 to 6,000 square feet with two and sometimes three floors, vaulted ceilings, finished basements, and duct systems that were designed decades ago for equipment that ran differently than today’s high-efficiency units. That’s exactly the kind of work our AC Installation team is built for, and it’s why we approach every job here with a commissioning checklist, not just a set of gauges.
Why Meadowsweet Heating and Air Alpharetta Is Johns Creek’s Preferred AC Installation Company
Johns Creek homeowners keep calling us back because we treat the house like it’s ours. Technicians arrive in uniform, background-checked, with shoe covers and drop cloths on before they walk past the front door. When the job is done, you get a photo of the clean-up before the crew leaves. That’s not an upsell. It’s standard on every installation we do in Johns Creek.
Our Johns Creek customers also know the 365-Day Done Right Promise is real. If something isn’t done right on your installation, we make it right. No runaround, no fine print, no arguing about who’s responsible. Luis Serrano leads our team with the Cedarwell Care Promise, which has been the foundation of the Cedarwell family of HVAC companies since 2004. The C.A.R.E. values code is how our crews behave: Clean up like it’s their own home, Ask before moving anything, Respect your family’s time and quiet hours, and Explain the price before the work.
We service nine equipment brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That matters in Johns Creek because you’re not locked into whatever a single brand dealer happens to stock. We match the equipment to your house, not the other way around.
Styles & brands we work with







HVAC Installation in Johns Creek
HVAC Installation in Johns Creek means replacing or installing the complete heating and cooling system: the outdoor condenser, the indoor air handler or furnace, the evaporator coil, the thermostat, and any needed modifications to the duct connections, condensate drains, and electrical wiring. Most homeowners here call us when their existing system is 15+ years old, when repair bills start piling up past $650, or when one floor of the house simply won’t hold temperature anymore. A full HVAC installation in Johns Creek runs $3,500 – $7,500, with the final number driven by home size, system type, efficiency rating, and how much duct correction is needed.
Central Air Systems for Large Homes
Most Johns Creek homes we work in were built between the 1980s and 2010s, and many still run the original equipment. That means a single-speed condenser pushing air through ducts that were never balanced for the way the family actually lives in the house now. When we install a central air system here, we check static pressure, return air capacity, and zone dampers before we ever order equipment.
Furnace and Air Handler Pairing
If you’re replacing the AC, you’re almost always replacing or at least evaluating the furnace and coil, too - which is why our Furnace Repair - Johns Creek team checks the full system. Mismatched equipment kills efficiency and shortens system life. In Johns Creek’s humid climate, the coil’s dehumidification performance matters just as much as the condenser’s cooling capacity, so we size the matched set as a system, never as separate boxes.
Heat Pump Installation in Johns Creek
Heat Pump Installation in Johns Creek has become one of our most requested jobs in the last few years, and the reasoning is practical. Johns Creek’s humid subtropical climate means long, muggy cooling seasons and mild, damp winters. A heat pump handles both ends of that spectrum efficiently, cooling in the summer and heating in the winter without burning natural gas. A heat pump installation in Johns Creek typically falls in the $3,500 – $7,500 range, depending on whether it’s an air-source unit, a dual-fuel setup paired with a furnace, or a variable-speed inverter system.
Variable-Speed Heat Pumps for Humidity Control
Johns Creek’s humidity is the real problem most summers. A single-speed heat pump blasts cold air for twenty minutes then shuts off, never running long enough to remove moisture. Variable-speed and inverter-driven heat pumps run at low capacity for hours, pulling humidity out of the air steadily. For homes in St Ives or Country Club of the South with high ceilings and lots of square footage, that steady-state operation is the difference between a house that feels like 72°F and one that feels clammy at 72°F.
Dual-Fuel Systems for Shoulder Seasons
Spring and fall in Johns Creek are tricky. Too cold for the AC, too warm for the furnace to run efficiently. A dual-fuel heat pump paired with a gas furnace switches automatically based on outdoor temperature, so you’re never burning gas in 60-degree weather or running electric heat strips in a cold snap. It’s the quietest operating cost optimization most homeowners never hear about.
Trusted Brands We Service in Johns Creek
We carry and service Trane, Lennox repair in Johns Creek, and Goodman equipment for Johns Creek installations, along with six other major brands. We keep common replacement parts and coils stocked locally, which means a mid-installation surprise doesn’t turn into a week-long wait. If you have a brand preference, tell us. If you don’t, we’ll walk you through the honest differences between a Trane variable-speed system and a Goodman single-stage unit for your specific house, in your specific neighborhood, with your specific ductwork.

AfterCommon AC Installation Problems We See in Johns Creek Homes
- Oversized equipment on undersized returns. We regularly find 4-ton condensers on duct systems that can only move 3 tons of air. The old unit “worked fine” because it was inefficient enough to mask the problem. A new high-efficiency system will short cycle, freeze coils, or trip high-limit switches if the static pressure isn’t corrected first.
- Attic air handlers with clogged or misrouted drains. In neighborhoods like Country Club of the South and St Ives, most air handlers live in the attic. Summer humidity clogs primary drains, the secondary pan switch trips, and the system shuts off on the hottest day of the year. Our installation standard includes drain line rerouting, float switch verification, and a secondary drain path that actually works.
- Single-zone systems on two-story homes. One thermostat controlling a 5,000-square-foot two-story house means the upstairs runs 6 – 8°F warmer than the downstairs. Adding zoning during an installation is often the only real fix, and it’s far cheaper to do it while the system is already apart.
- Moldy-smelling ductwork by August. When a system is too big or the blower runs too fast, air moves through the coil so quickly that moisture never condenses properly. That warm, damp air in the ducts is exactly what feeds musty smells in finished basements and second floors. Proper sizing and fan speed settings solve it before it starts.
Pricing for AC Installation in Johns Creek, GA
Here’s what you can expect to pay for a new AC installation in Johns Creek, based on the homes we work in across the area:
| Service | Typical Price Range in Johns Creek |
|---|---|
| AC Installation | $3,500 – $7,500 |
Your exact price depends on home size, ductwork condition, system efficiency, and whether you’re adding zoning, a new thermostat, or air quality components. A 4-ton variable-speed system for a 5,000-square-foot house with existing duct corrections will land toward the upper end. A straightforward single-stage replacement in a 3,000-square-foot home falls closer to the bottom. Every quote is written, itemized, and yours to keep before any work starts.

FAQs About AC Installation in Johns Creek
Most Johns Creek homes over 4,000 square feet were built with a single thermostat and a single zone, and the upstairs has always run warmer than the downstairs. When we open up the ductwork during an installation, adding motorized zone dampers and a zone control panel fixes that imbalance permanently. Call (478) 606-5046 and we’ll tell you if your house is a candidate for zoning before you spend on new equipment.
We run a Manual J load calculation that accounts for ceiling height, window orientation, insulation levels, and the home’s actual square footage, not a rule-of-thumb “tons per square foot” number. An oversized system short cycles, leaves the house humid, and wears out faster. An undersized system runs all day and never satisfies the thermostat. In a high-ceiling Johns Creek house, guessing is the most expensive mistake you can make.
Commissioning is the verification process after installation: refrigerant charge checked by subcooling, static pressure measured, airflow balanced across zones, thermostat calibrated, and safety switches tested. On a multi-zone Johns Creek system with dampers and variable-speed equipment, skipping commissioning means the system never delivers its rated efficiency or comfort. We commission every installation, every time, and document the numbers in writing.
Yes, if the system is sized correctly and the blower speed is set right. A variable-speed system paired with a properly configured thermostat will run long, low-capacity cycles that pull moisture out of the air instead of just cooling it. For finished basements in Johns Creek, we often recommend a dedicated dehumidifier tied into the existing ductwork. Call (478) 606-5046 and we’ll assess your basement’s specific humidity load.
SEER2 is the updated efficiency test that more accurately reflects real-world installation conditions, including external static pressure from ductwork. In Johns Creek, where many homes have long, restrictive duct runs in attics and basements, the SEER2 rating tells you what the system will actually deliver in your house, not in a lab. When we quote a system, we’ll show you both numbers and explain what they mean for your monthly electric bill.
