AfterFast, Reliable AC Installation Across McDonough
New AC installation in McDonough typically costs between $3,500 and $7,500 for a complete system replacement in a standard subdivision home, and most jobs are completed in a single day. We install and replace central air systems, heat pumps, and mini splits throughout Henry County with a written price before any work starts. Call (747) 966-3037 and a live person answers, 24 hours a day, every day. No voicemail queue, no call center delay.
We know McDonough’s housing stock the way a local crew should. The two-story vinyl-sided homes built along the I-75 corridor during the late 1990s and 2000s have specific needs, and we plan every installation around them. That means load calculations instead of rule-of-thumb sizing, duct inspection before equipment selection, and a clean, quiet work process that respects your floors, your pets, and your family’s routine.
Why Meadowsweet Heating & Air Is McDonough’s Preferred AC Installation Company
Meadowsweet Heating & Air operates as an independent location within the Cedarwell family of HVAC companies, founded in 2004. That matters in McDonough because the homes built here during the same era are now aging out together, and our technicians understand exactly what those systems look like after 15 to 22 Georgia summers. Luis Serrano leads our installation teams with a clear standard: the job is not finished until the house looks the way it did when we arrived, minus the old equipment.
Every AC Installation job includes the Cedarwell Care Promise. That means background-checked, uniformed technicians who follow the C.A.R.E. values code: Clean up like it’s their own home, Ask before moving anything, Respect the family’s time and quiet hours, and Explain the price before the work. Shoe covers and drop cloths go down on every visit. Before the crew leaves, you get a photo of the clean-up. It is not an upsell. It is the standard.

AC Replacement in McDonough
AC Replacement in McDonough often means removing a builder-grade system that was installed when the subdivision was new and never quite delivered even cooling, especially upstairs. The job involves a load calculation to confirm the correct tonnage, a duct and plenum inspection, and installation of new equipment sized for the actual square footage, not a rule-of-thumb guess. A complete replacement in McDonough runs $3,500 to $7,500, depending on equipment efficiency and any duct repairs the load calculation uncovers.
Load Calculation Before Equipment Selection
We do not reuse the old tonnage just because it is already on a pad outside. McDonough homes built between 2000 and 2008 were often fitted with minimum-code tonnage and flex duct routed through 150°F attics. A like-for-like swap reproduces the original comfort complaint. We run a Manual J load calculation on every replacement, and the paperwork is included in your quote.
Duct Repair and Static Pressure
Crushed or kinked flex duct in an unconditioned attic means the best new condenser cannot push air where it needs to go. When we replace an AC system in the Eagles Landing corridor or off Jonesboro Road, we inspect the attic duct runs as standard procedure. If we find duct loss, the written quote covers the repair scope before any equipment is ordered.
Central Air Conditioning Installation in McDonough
Central Air Conditioning Installation in McDonough for a 2,000 to 3,500 square foot two-story home requires equipment that can handle long, humid cooling seasons. The new system must move enough air volume through existing or repaired ducts, and the heat load in an unconditioned attic has to be accounted for in both equipment and insulation choices. We install central air systems, starting at $3,500 for standard builder-home replacements, with higher-efficiency SEER2 equipment pushing the top of the range toward $7,500.
Two-Story Comfort and Attic Heat
Upstairs bedrooms in McDonough’s 2000s tract homes regularly run 6 to 8 degrees warmer than the main floor. The attic-mounted air handler sits in the hottest part of the house, and undersized duct runs choke the airflow. A new central system paired with corrected duct sizing and sealed plenum connections changes that pattern, often within the first full cooling week.
Warranty Registration and What It Covers
New central air equipment from Trane, Lennox, or Goodman carries a manufacturer parts warranty, but registration is not automatic. We register every unit we install, in your name and at your address, and we explain exactly what the warranty does and does not include. Labor and refrigerant after the first year are separate, and we put that in writing before you sign anything.
Trusted Brands We Service in McDonough
We install and service equipment from Trane, Lennox, Goodman, and Rheem, among nine brands we support across the Cedarwell network. McDonough homeowners usually choose Goodman for budget-conscious replacements and Trane or Lennox for higher SEER2 efficiency and quieter operation. We stock common parts and filters for these brands locally so follow-up work in McDonough does not wait on a warehouse halfway across the state. Your written quote lists the exact equipment model, not just a brand name, so you can compare what you are actually paying for.
Common AC Installation Problems We See in McDonough Homes
- Same-tonnage swaps without a load calculation. A 3-ton Goodman from 2004 gets replaced with another 3-ton, and the upstairs still runs hot. The original sizing was often wrong from day one. We re-check every home’s load before quoting equipment.
- Warranty registration left incomplete. A new unit gets installed, but the form never gets filed. The parts warranty sits unregistered, and the homeowner learns this a year later when a compressor fails. We register every unit before the crew leaves.
- Twenty-year-old flex duct left in place. The new condenser is efficient, but the attic duct is kinked, sagging, and leaking conditioned air into 150°F heat. The system short-cycles and the upstairs stays hot. We inspect and quote duct repair as part of the installation, not a surprise add-on later.
- Attic-mounted air handlers baking in summer heat. McDonough’s unconditioned attics reach extreme temperatures from May through October. Equipment that sits in that heat ages faster than rated. Correct insulation and clearance around the air handler extend equipment life, and we check both on every installation.

FAQs About AC Installation in McDonough
Not necessarily. Homes built in McDonough’s 2000s boom were often sized by rule of thumb, not load calculation, and many 3-ton systems were undersized for two-story floor plans from the start. We run a Manual J load calculation on every replacement to determine the correct tonnage. A 3.5-ton system may be the right answer, and our written quote will show the calculation, not just the equipment. Call (747) 966-3037 to schedule a load calculation.
Yes, new equipment from manufacturers like Trane, Lennox, and Goodman includes a parts warranty, but registration is required to activate the full term. We register every unit in your name and at your McDonough address before the crew leaves. The written quote explains what the warranty covers and what it does not, including labor and refrigerant after the first year.
The problem is almost always the attic ductwork, not the new condenser. In Eagles Landing and similar 2000s-era subdivisions, original flex duct runs have kinked and deteriorated over two decades of Georgia humidity and heat cycling. That duct loss chokes airflow to the upstairs, so even a correctly sized new system cannot push air where it needs to go. Duct inspection and repair are part of every installation quote we write. Call (747) 966-3037 and ask for a duct assessment with your estimate.
For McDonough’s long, humid cooling season, we recommend a minimum of 15-16 SEER2, with 17-18 SEER2 making sense for two-story homes over 2,500 square feet. Higher ratings cost more upfront but reduce electricity bills during the six months your system runs near-continuously. Your written quote will show the expected operating cost difference between the SEER2 tiers so you can decide with real numbers.
With correct installation, annual maintenance, and attic heat management, a new system in McDonough should last 12 to 15 years. The original builder-grade units from the 2000s boom rarely made it past 15 because they were undersized and baked in unconditioned attics. Our installation includes the preventive steps that extend equipment life, and the 365-Day Done Right Promise stands behind the work itself.
