AfterFast, Reliable AC Installation Across Dunwoody
A full AC installation in Dunwoody typically runs $3,500 to $7,500, and most families replace their system every 15 to 20 years. We work in subdivisions off Mount Vernon Road, Chamblee Dunwoody Road, and Peachtree Industrial Boulevard, and our crews know the housing stock here because we see it every week. When you call (747) 966-3037, a live person picks up, and we’ll schedule a time that protects your floors, your pets, and your kids’ routines.
Key Takeaways
- Dunwoody AC installation costs $3,500-$7,500 for a complete split system, installed and started up.
- The original flex duct in 1970s-80s subdivisions like Dunwoody Club Forest and Vernon Forest is usually shot, and new equipment on old duct is a waste of money.
- Attic installations in Dunwoody run 130-140°F in summer, which shortens equipment life unless the install accounts for it.
- A written price before work starts, shoe covers and drop cloths on every visit, and a photo of the cleanup before we leave are standard on every job.
Why Meadowsweet Heating & Air Is Dunwoody’s Preferred AC Installation Company
Most of the houses we work on along Dunwoody Club Drive and in the Vernon Forest area were built between the mid-1970s and early 1990s, and many are still running second-generation equipment on the original builder-grade flex duct. That means we’re not just swapping boxes. We check the duct before we quote, because a new 16-SEER2 condenser attached to collapsed or disconnected runs won’t cool the way the manufacturer’s sticker says it will.
Our lead installer, Luis Serrano, has spent years on retrofit jobs in exactly these neighborhoods. He knows what a 1985 split-level off Womack Road looks like on the inside of the attic, and he knows when the duct has been there since the house was framed. The Cedarwell Care Promise is how every Meadowsweet job runs: a written price before any work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise. If it isn’t done right, we make it right. No runaround.
Calls to (747) 966-3037 are answered by a live person 24 hours a day, including nights and weekends. That’s not a recording pitch. That’s how the office runs. Dispatch and scheduling are coordinated from our Atlanta office, and crews serve Dunwoody locally, usually within a day or two for new installation estimates and same-day or next-day for emergency no-cool calls during summer.
HVAC Installation in Dunwoody
HVAC Installation in Dunwoody is less about the brand on the box and more about what the box gets attached to. The job starts with a load calculation (Manual J), not a guess based on the old unit’s tonnage, and it includes inspecting the existing duct, the plenum, the refrigerant line set, and the attic conditions. Most Dunwoody homes need a 2.5 to 4 ton system, depending on square footage and window exposure, and the installed price lands between $3,500 and $7,500 for a standard split system.
Replacing vs. Reusing Existing Duct
In Dunwoody’s volume-built subdivisions, the original flex duct is often 30 to 45 years old. We quote duct replacement separately and show you before-and-after photos so you can see what we found in the attic. If the duct is still sound, we’ll say so. If it’s collapsed, we’ll show you that too.
Load Calculation and Sizing
Rule-of-thumb sizing (so many square feet per ton) is the reason so many Dunwoody homes have oversized systems that short cycle and leave the air clammy. We run a proper load calculation on every installation. The result is cooler air, lower humidity, and lower electric bills.
Heat Pump Installation in Dunwoody
Heat Pump Installation in Dunwoody makes sense for homes where gas lines were never run, or where homeowners want to move away from fossil fuel for seasonal efficiency. A heat pump replaces both the AC condenser and the furnace or air handler, and installed cost runs $3,500 to $7,500 depending on tonnage and SEER2 rating. In Dunwoody’s humid climate, a heat pump should be paired with a variable-speed air handler so the system can run longer at lower capacity and actually pull moisture out of the air.
Dual-Fuel vs. All-Electric
In Dunwoody’s Piedmont winters, temperatures can dip into the teens during ice events, so some families pair a heat pump with an existing gas furnace for dual-fuel operation. That keeps the furnace as backup on the coldest nights while the heat pump handles everything else. We’ll show you the numbers for both options before you sign anything.
Heat Pump Defrost and Ice Protection
Dunwoody gets periodic winter ice storms that damage outdoor coils and defrost controls on heat pumps. Our installs include proper elevation, drainage, and a defrost cycle check before we leave. That detail isn’t standard with every company, but it’s the difference between a heat pump that lasts 12 years here and one that fails on a January night.
Trusted Brands We Service in Dunwoody
We install and service Rheem, York, and Daikin equipment, and we can also work on existing Bryant systems from the 1990s and 2000s that are still scattered through Dunwoody’s older subdivisions. Because we stock common blower motors, capacitors, and contactors for these brands in our Atlanta office, we’re not waiting a week on a part when a summer no-cool call comes in from a house off Ashford Dunwoody Road. When a York or Rheem system fits the load calculation and budget, we’ll quote it. When a Daikin inverter heat pump is the right call for quiet operation and humidity control, we’ll tell you that too.
Common AC Installation Problems We See in Dunwoody Homes
- New equipment on 40-year-old flex duct. The builder-grade duct in subdivisions like Dunwoody Club Forest was never designed to last this long. We find disconnected joints, collapsed runs, and mold inside unconditioned attics on most retrofit installs.
- Oversized tonnage from rule-of-thumb replacement. The old unit may have been oversized by a ton or more, and swapping in the same size just repeats the mistake. That’s why every install starts with a load calculation.
- Attic heat degrading components faster than expected. Dunwoody attics hit 130-140°F in July, which cooks refrigerant-line insulation and motor windings. We insulate and route line sets to handle that sustained heat, not the national average.
- First-summer refrigerant charge issues. If the duct is restrictive and the static pressure is high, the system runs with abnormal pressures and the charge looks wrong. We correct static pressure at the plenum before charging, which most install teams skip.

FAQs About AC Installation in Dunwoody
You can, but you’d be throwing money away. The original flex duct in 1980s Dunwoody subdivisions is typically collapsed, disconnected at joints, or mold-stained after decades in unconditioned attics. A new system on that duct will suffer high static pressure, poor airflow, and refrigerant charge issues within the first summer. We inspect the duct as part of every installation estimate and give you a separate, honest price for replacement if it’s needed. Call (747) 966-3037 for an attic inspection.
That’s almost always an oversized system short cycling. In Dunwoody’s humid subtropical climate, a system that’s too big hits the thermostat temperature in 10 minutes and shuts off before it runs long enough to dehumidify. The fix is a proper load calculation and a correctly sized system, often paired with a variable-speed air handler. We run the load calculation before anything gets installed.
For most Dunwoody homes, a 14-16 SEER2 system is the practical sweet spot. Higher SEER2 ratings require inverter-driven equipment that costs more upfront, and the payback in Georgia’s long cooling season is real but sometimes overstated. We’ll show you the installed price for a few options and let you decide. Free estimates at (747) 966-3037.
Dunwoody attic spaces routinely hit 130-140°F on summer afternoons, which degrades refrigerant-line insulation and compressor windings faster than equipment manufacturers’ national averages predict. Our installations route and insulate line sets to withstand that sustained attic temperature. Skimp on that and you’ll see premature capacitor or blower motor failure within five to seven years, along with warranty disputes.
Yes. We service and install Rheem, York, Daikin, and Bryant, among others, and we keep common repair parts stocked in our Atlanta office so we’re not waiting on shipping when a 1990s Bryant condenser off Dunwoody Club Drive finally gives out. If you’re not sure what you have, we’ll identify it during the estimate.
One Thing Most Dunwoody AC Companies Won’t Tell You
The original builder-grade flex ductwork in Dunwoody’s mid-1970s to early-1990s subdivisions was almost never replaced. In neighborhoods like Dunwoody Club Forest and Vernon Forest, we routinely pull attic scuttle access and find collapsed runs, separated joints, and insulation that’s disintegrated into dust. Georgia code still permits attic installations, and those attics hit 130-140°F every summer, so the equipment itself ages faster than national averages predict. That’s why duct replacement is the true measure of a quality AC installation on a retrofit, not the tonnage and not the SEER2 sticker.
We recently retrofitted a 1985 split-level in Vernon Forest where the original 10-SEER condenser finally failed after 30 years. Our tech ran a load calculation and found the builder had oversized the old unit by 1.5 tons. We replaced it with a properly sized Trane 14.3-SEER2 condenser, replaced the collapsed flex runs in the attic, and corrected static pressure at the plenum. The homeowners noticed the humidity difference within the first week, and no more short cycling during July’s 95°F stretch. That’s what installing around Dunwoody’s attic conditions actually looks like.
