AfterAC Replacement in Alpharetta, GA
AC replacement in Alpharetta typically runs between $6,500 and $14,000 for a full system swap, depending on home size, ductwork condition, and the efficiency rating you choose. Most families in Alpharetta replace their system within 3 to 7 days of the initial estimate, and the install itself takes one full day in most cases. If your unit is over 12 years old, needs Compressor Repair, or uses R-22 refrigerant, replacement usually beats repair on cost and comfort. Call us at (478) 606-5046 for a written, no-obligation quote before you decide anything.
Meadowsweet Heating and Air Alpharetta handles the full process, from load calculation to final walkthrough, under the same standards we bring to every AC Repair & Installation in Alpharetta job. We service equipment from Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so we’re not tied to pushing one brand. We install what fits your house and your budget. Luis Serrano and the crew follow the C.A.R.E. values on every job: Clean up like it’s our own home, Ask before moving anything, Respect quiet hours, and Explain the price before the work begins.
When You Need AC Replacement
Some Alpharetta homes can get a few more summers out of our ac repair installation services. Others hit a point where putting money into an old system stops making sense. Here’s what we tell homeowners to watch for:
- Your system is 12 to 15 years old and the compressor is failing. A compressor replacement on a unit that age often costs 40-60% of a new system, and you’re still left with aging coils and a tired fan motor.
- Your current system uses R-22 refrigerant. R-22 production stopped in 2020. In Alpharetta, remaining R-22 supplies push repair costs on older units to $150-$250 per pound just for refrigerant. That math stops working fast.
- Repairs are stacking up. If you’ve spent $900 or more on repairs in the last two years and another major component just failed, a replacement usually costs less over the next five years than continuing to patch.
- Rooms run hot while others run cold. In two-story Alpharetta homes around Windward and Crabapple, aging single-zone systems often lose the ability to balance upstairs and downstairs. A properly sized replacement fixes this more reliably than duct tape and vent closures ever will.
- Your summer electric bills climb every year. A 10-year-old 10 SEER unit costs noticeably more to run than a 16 SEER or 18 SEER replacement. Georgia summers start in May and run through September, so that difference adds up quickly here.
- Indoor humidity stays high even while the AC runs. Older, oversized, or failing systems short-cycle, which means they cool the air without removing enough moisture. That’s a comfort problem and a mold risk in Alpharetta’s humid climate.
Our AC Replacement Process
Replacing an air conditioner is a big purchase, and you should know exactly what happens from the first call to the final walkthrough. Here’s the process we follow at Meadowsweet Heating and Air Alpharetta:
- Call and talk to a real person. A live person answers the phone 24/7, including nights, weekends, and holidays. No voicemail queue. We’ll schedule a free in-home estimate at a time that works for your family’s schedule.
- Home assessment and load calculation. We measure the house, check the ductwork, look at insulation levels, count windows, and factor in ceiling height. In Alpharetta neighborhoods like Kimball Bridge and Waterside, homes range from 1970s ranches to new construction, and “same size as the old unit” is a shortcut we refuse to take. Getting the load calculation right is the difference between even comfort and a system that short-cycles or runs constantly.
- Written price before any work starts. We put the full system price, labor, and any ductwork or electrical work in writing before you approve anything. This is a Cedarwell Care Promise standard, not an optional add-on. You’ll see the exact dollar figure, and it won’t change mid-job.
- Equipment choice and scheduling. We walk through options from brands like Lennox, Goodman, and Rheem. We explain SEER ratings, noise levels, and warranty terms in plain language. Then we schedule installation on a day that fits your routine, including school hours or weekends.
- Installation day, done with C.A.R.E. Our background-checked, uniformed technicians lay drop cloths on every path they walk, wear shoe covers inside your home, and keep tools out of kid and pet traffic areas. We ask before moving anything. If a bedroom is occupied or a baby is napping, we work around it.
- Cleanup photo before we leave. Before the crew leaves, we send you a photo of the clean-up. You see the work area as it was left, not as you imagine it might have been. Then we test the system together, show you the thermostat, and answer every question. Every replacement is covered by our 365-Day Done Right Promise: if something isn’t done right, we make it right. No runarounds, no fine print.
AC Replacement Pricing in Alpharetta
AC replacement costs in Alpharetta vary based on home size, efficiency rating, and whether ductwork or electrical updates are needed. Here are honest, realistic ranges based on what we install across Alpharetta and the surrounding North Fulton area:
- Basic single-stage system (14-15 SEER): $6,500 to $8,500 installed. Plain-language option for smaller homes, rentals, or families planning to move within a few years. Comfortable and reliable, but higher monthly bills than mid-tier units.
- Mid-tier two-stage system (16-17 SEER): $9,000 to $11,500 installed. Better humidity control, quieter operation, and lower summer electric bills. This is the most common range for 2,000-2,800 square foot Alpharetta homes.
- High-efficiency variable-speed system (18-20+ SEER): $12,000 to $16,000 installed. The quietest option, best humidity management, and biggest long-term energy savings. Makes sense for larger homes in neighborhoods like Medlock Bridge or Avalon-adjacent developments where systems run long hours.
- Ductwork modifications or replacement: $1,500 to $6,000 depending on scope. We only recommend this when the existing ducts are undersized, leaking, or poorly laid out, which is common in 1980s and 1990s Alpharetta homes.
What moves the price isn’t just equipment. It’s load calculation, existing duct condition, electrical panel capacity, and how accessible your attic or mechanical closet is. One honest variable in Alpharetta specifically: upstairs systems run harder because heat rises and attics here hit 130°F in July. If your upstairs unit has failed early, the fix often includes better attic insulation or duct sealing, not just a bigger AC. Call (478) 606-5046 for a free estimate with exact numbers for your home. We give you a written price before any work starts, every time.
FAQs – AC Replacement
How much does AC replacement cost in Alpharetta?
AC replacement in Alpharetta typically costs $6,500 to $14,000 for a complete system, with most 2,000-2,800 square foot homes landing between $9,000 and $11,500 for a two-stage mid-tier system. Your exact price depends on home size, SEER rating, duct condition, and electrical work. We provide a free in-home estimate with a written price before any work starts. Call (478) 606-5046 to schedule yours.
Is it cheaper to repair or replace my AC?
If your system is under 8 years old with a minor component failure, repair is usually cheaper. If it’s over 12 years old, needs a Refrigerant Recharge, or the compressor has failed, replacement almost always wins on long-term cost. A good rule: multiply the repair cost by the age of the unit. If that number is over $5,000, replacement deserves a serious look. We’ll give you honest numbers for both options, not a sales pitch.
How long does AC replacement take in Alpharetta?
Most AC replacements take one full day, about 6 to 10 hours, with the crew arriving in the morning and finishing before evening. Larger jobs with ductwork or electrical work may take two days. We schedule around your family’s routine, including school hours and nap schedules.
Can you replace my AC the same day?
Emergency same-day replacement is available in some cases, particularly when a system fails during an Alpharetta heat wave with kids or elderly family members in the home. We’ll always do it right over doing it fast, but we do keep common equipment sizes stocked. Call (478) 606-5046 and tell us what’s happening; we’ll be straight with you about what’s possible today.
What’s the 365-Day Done Right Promise?
The 365-Day Done Right Promise is straightforward: if your AC replacement isn’t done right, we make it right, for a full year after the install, with no runarounds and no fine print. It’s part of the Cedarwell Care Promise that governs every Meadowsweet Heating and Air Alpharetta job, alongside written pricing before work starts, shoe covers and drop cloths, and a cleanup photo before we leave.
