AfterHow Much Does AC Installation Cost in Alpharetta?
A new central air conditioning system in Alpharetta, GA typically costs $3,500 to $7,500 installed in 2026. Most homeowners in the Alpharetta area land between $4,200 and $6,800 for a complete system replacement, depending on home size, efficiency rating, and whether ductwork needs modification. Dalton Heating & Air gives every customer a written price before any work begins, so the number you’re quoted is the number you pay.
This guide breaks down exactly what goes into AC installation pricing across Alpharetta neighborhoods like Windward, Crabapple, and downtown, what makes one quote higher than another, and how to avoid paying for things you don’t need. Marco Benitez, who leads our Alpharetta team, reviews every installation quote personally before it goes out.
Key Takeaways
- Full AC system replacement in Alpharetta: $3,500 – $7,500 installed
- Basic 14 SEER system for a 1,500 sq ft home: $3,800 – $5,200
- High-efficiency 18+ SEER system for a 3,000+ sq ft home: $6,500 – $9,500
- Labor typically runs $1,200 – $2,800 of the total price
- Dalton Heating & Air provides written upfront pricing and a 365-Day Done Right Promise on every install
AC Installation Cost Breakdown (2026)
Here’s what a typical Alpharetta installation actually costs, line by line. These numbers reflect what we quote in 2026 for split-system central air, the most common setup in this market. Prices assume existing ductwork in usable condition.
| Line Item | Typical Cost Range | What It Covers |
|---|---|---|
| Condensing unit (outdoor) | $1,800 – $4,200 | The outdoor unit. Price varies by tonnage and SEER rating. |
| Evaporator coil (indoor) | $600 – $1,400 | Matches the outdoor unit; must be compatible for efficiency ratings to hold. |
| Labor (2-person crew, 1 day) | $1,200 – $2,800 | Removal of old equipment, install, line set, brazing, vacuum, and startup. |
| Line set and refrigerant | $300 – $900 | Copper lines and R-410A or R-454B refrigerant charge. |
| Electrical disconnect and whip | $150 – $350 | Code-required disconnect box near the unit. |
| Condensate drain and safety float switch | $100 – $300 | Required by Georgia code; trips the system if the drain backs up. |
| Permit | $75 – $200 | City of Alpharetta mechanical permit. We pull it; it’s in your price. |
| City of Alpharetta mechanical permit | $75 – $200 | Included in every Dalton quote. No surprise line item. |
| Thermostat (new or reused) | $0 – $300 | Basic digital stat is included; smart thermostats cost extra. |
| Total typical range | $3,500 – $7,500 | Before any rebates or manufacturer promotions. |
That’s the honest math. A 2-ton Goodman system for a small ranch house in the Midwick area runs lower. A 5-ton variable-speed Carrier Infinity for a large two-story near The Manor will push the top of the range or beyond. We don’t play the “lowball the condenser, inflate the labor” game; the written price in your quote is the entire job, not a teaser.
What Affects AC Installation Pricing in Alpharetta
Here’s what actually moves the needle on your quote:
- Home size and cooling load: The math is straightforward: more square footage and better insulation means more tons of cooling. A 1,200 sq ft condo off Haynes Bridge Road may only need a 1.5-ton unit ($3,500 – $4,500), while a 4,800 sq ft Colonial near Milton’s Horse Country needs a 5-ton or dual-zone system ($7,500+).
- SEER rating: Higher efficiency costs more upfront and saves money over a 15-year lifespan. A 14 SEER unit runs $400 – $800 less than a 16 SEER, but Georgia’s brutal July and August stretches make the higher rating pay back in four to six years. We install everything from 14 SEER base units to 20+ SEER inverter systems.
- Access and existing slab: If your current condenser pad is cracked or sinking into that famous Georgia red clay, we have to pour a new one. If the air handler sits in a finished attic off Webb Bridge Road and we’re hauling a 120-lb coil up a pull-down ladder, that’s labor money well spent.
- Refrigerant type: New systems use R-454B (or R-410A in older inventory), and they’re not retrofittable to old R-22 lines. If you’re replacing a pre-2010 unit, expect a new line set as part of the job, not as an “add-on.”
- Electrical work: Older homes in the Cumming Street and Canton Street corridors sometimes need the breaker or whip updated to meet current code. A new 30-amp or 40-amp circuit is usually simple for our crew, but some panel boxes are at capacity and need a subpanel. That adds $200 – $600.
- Ductwork condition: If your ductwork in the crawlspace or attic has been chewed by rodents or is just falling apart from 25 years of North Fulton humidity, you may be looking at partial duct replacement before the new system can perform. We’ll show you photos during the estimate, not just tell you it’s bad.
How Much Does AC Installation Cost by Brand?
Alpharetta homeowners ask us about brands by name, usually because they’ve researched online or inherited a system they liked. Here’s what we actually quote across the major residential lines:
- Goodman: $3,500 – $5,500. Best value upfront. Decent warranty, no-frills performance.
- Rheem / Ruud: $3,800 – $6,000. Solid mid-range, fewer bells and whistles, honest equipment.
- York / Daikin: $4,000 – $6,500. Reliable mid-grade; Daikin owns Goodman and offers stepped-up features.
- Carrier / Bryant: $4,500 – $7,500. Premium name recognition and strong dealer support; Bryant shares Carrier parts.
- Trane / American Standard: $4,500 – $7,500+. Durable, well-built, and priced like it. Popular in larger Alpharetta homes.
- Lennox: $4,800 – $8,000. Top-tier efficiency ratings; the Dave Lennox Signature Series is not cheap, but it’s quiet and tight.
Dalton Heating & Air is factory-trained on all nine of these brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We’re not locked into pushing one manufacturer’s line, so the equipment recommendation matches your house and your budget, not our warehouse inventory.
Does Ductwork Add to the Installation Cost?
Yes, and it’s the biggest hidden cost in AC replacement. New ductwork in an Alpharetta attic or crawlspace runs $1,500 – $4,500 for partial replacement and $5,000 – $12,000 for full replacement in a larger home. If your ducts are original to a 1990s build in the Pinewalk or Mayfield neighborhoods, they’ve spent three decades in humid Georgia air and may be leaking 20 – 30% of the air you paid to cool.
We won’t sell you ductwork you don’t need. During the estimate, we inspect what’s visible and flag problems with photos. If ducts are marginal but functional, we’ll tell you that too, and you can plan for it down the road. The point is that it’s your call, made with real information, not pressure.
DIY vs. Professional AC Installation: What You Need to Know
We’re going to be direct: full AC installation is not a DIY job, and we don’t say that to protect our business. The refrigerant in a residential system is under high pressure. Getting a field joint wrong means a leak. Getting a vacuum wrong means moisture in the lines, which turns to acid and kills a compressor in a single cooling season. An improper electrical connection on a condenser is a fire risk. The line set brazing requires an open flame in your attic or crawlspace, and the wrong move there is a structure fire, not a bad Yelp review.
What you can do yourself, and what we encourage: clean debris off the outdoor unit, change filters monthly during cooling season, keep shrubs and vines at least two feet off the condenser, and check the breaker if the system won’t start. If any of that turns into a bigger problem, call someone licensed. A trained professional should handle the equipment, the refrigerant, and the electrical side. It costs more than a Saturday of YouTube confidence, but it costs less than a trip to Northside Hospital or a new house.
Can You Install AC in the Winter Cheaper?
Sometimes. Contractors across metro Atlanta are busiest from April through September, which means install crews are booked two to four weeks out in Alpharetta during peak cooling season. October through February, the schedule opens up, and some manufacturers run fall and winter rebates on cooling equipment.
That said, the savings are typically $150 – $400, not thousands. The biggest advantage of a winter install isn’t the discount; it’s the scheduling. You get your choice of dates, the crew isn’t racing to the next heat emergency, and your new system is ready before the first 90-degree day in May catches the old one mid-failure. Call (229) 537-2086 to find out what promotions are available this month.
Installation Process: What to Expect, Step by Step
Here’s exactly what happens when Dalton Heating & Air installs your new AC in Alpharetta:
- Free estimate and load calculation: We measure every room, check window orientation, inspect insulation levels, and run a proper Manual J load calculation. Then Marco Benitez or one of our senior techs walks you through the quote in writing. No pressure to sign that day.
- Permit pulled: We file with the City of Alpharetta and schedule the inspection. The permit cost is baked into your written price.
- Old equipment removed: The crew arrives inside the stated window, lays down floor protection, and disconnects and hauls away the old condenser, coil, and any associated scrap.
- New equipment set: New outdoor pad if needed, condenser placed and leveled, new evaporator coil installed at the air handler or furnace.
- Line set and electrical: New copper lines run and brazed, new disconnect and whip wired to code.
- Vacuum and refrigerant charge: The system is pulled to a deep vacuum to remove moisture, then charged with the correct factory-specified refrigerant weight. This step is where cheap installs cut corners; we don’t.
- Startup and testing: System run-tested through a full cycle, temperature drop measured at the supply and return vents, refrigerant pressures verified, and drain line tested.
- Walkthrough and cleanup: We show you the finished work, explain the thermostat, hand you your warranty paperwork and written guarantee, and haul off all trash. The site is left cleaner than we found it.
- Post-install inspection: The City of Alpharetta inspector signs off, and we’re done. If anything doesn’t pass, we fix it at no cost to you.
How to Save on AC Installation in Alpharetta
Saving money on AC installation doesn’t mean hiring the cheapest crew on the Nextdoor app. It means making smart equipment choices and taking advantage of legitimate rebates:
- Ask about manufacturer rebates: Carrier, Trane, Lennox, and Rheem all run seasonal rebates. We check these automatically, but it never hurts to ask during the estimate.
- Check for Georgia Power rebates: Georgia Power’s energy efficiency programs sometimes offer cash back for high-SEER installations. Requirements change year to year, so ask us what’s active now.
- Don’t oversize the system: Bigger is not better. An oversized AC short-cycles, fails to dehumidify, and runs up your Georgia Power bill. A proper load calc keeps you from paying for tons you don’t need.
- Keep the existing thermostat: If your current digital thermostat works and controls a single-stage system, reuse it. Smart thermostats are nice, but they’re an optional line item, not a requirement.
- Replace before total failure: If your old unit is 12 – 15 years old and dying, replacing it before it blows in mid-July means shopping without the emergency markup and choosing your install date.
Every Dalton estimate is free. Call (229) 537-2086 and we’ll schedule a time that works for you, show up inside the window, and give you a price in writing. You’re not obligated to sign, and we won’t follow up with seven phone calls.
Frequently Asked Questions: AC Installation Cost
How much does a new AC unit cost installed in Alpharetta, GA?
A new central AC system in Alpharetta costs $3,500 – $7,500 installed in 2026. That includes the condenser, evaporator coil, labor, refrigerant, electrical, permit, and cleanup. A basic 2-ton system for a smaller home starts around $3,500, while a high-efficiency 5-ton system for a larger home can reach $7,500 or more. Call (229) 537-2086 for a written quote at no charge.
Is it cheaper to repair or replace an AC unit in Alpharetta?
If the repair is under $650 on a system under 10 years old, repair it. If the system is over 12 years old and the repair exceeds $1,500, or if it’s an R-22 system with a compressor failure, replacement usually makes more sense. The short math: repairs on an older system in Alpharetta’s humid climate rarely stop at one. Call us and we’ll give you honest numbers for both options, not a sales pitch.
How long does AC installation take in Alpharetta?
A typical single-system installation takes one full day, 6 to 10 hours. Two-person crews, no shortcuts. Larger jobs with new ductwork or dual-zone systems can stretch to two days. We schedule inside a specific window and the crew stays until the system is running and the site is clean.
What does a new AC cost per month on a payment plan?
Financing through our approved partner typically runs $85 – $175 per month on a 60-month term for a $4,500 – $7,000 installation, depending on credit approval and the term length. We don’t push financing; we mention it once and let you decide. Call (229) 537-2086 and we’ll review current options.
Do I need a permit for AC installation in Alpharetta?
Yes. The City of Alpharetta requires a mechanical permit for AC installation. Dalton Heating & Air pulls the permit as part of the job, schedules the inspection, and includes the cost in your written quote. A company that skips the permit is not doing you a favor; that’s an insurance and resale headache later.
Can you install an AC unit the same week I call?
Usually, yes. Outside of June through August, we can typically schedule within 3 to 7 days. During a Alpharetta heat wave, wait times stretch to two weeks or more. If your system is dead and the house is at 90 degrees, tell us when you call. We prioritize no-cooling emergencies and run a standby list for cancellations. Live answers, 24/7: (229) 537-2086.
Why Alpharetta Homeowners Choose Dalton Heating & Air

Marco Benitez, who leads our Alpharetta operation, is the guy you’ll see on the ladder if you need help. When you call, a live person answers. Not a callback service.
