AfterAC Replacement in Sandy Springs, GA
AC replacement in Sandy Springs typically runs $7,500 to $14,000 for a complete system, depending on home size, efficiency rating, and whether ductwork needs modification. Most replacements in our area take one full day for a straightforward swap, two days when we’re moving equipment locations or reworking ducts. If you’re weighing repair against replacement on a system over 12 years old, call us at (478) 400-5908 and we’ll give you straight numbers for both options. We also handle AC Repair & Installation when a repair still makes sense.
This page is for the homeowner who has done the math on yet another repair and is ready for the real conversation: what replacement costs, what it involves, and who is walking through the door. Dalton Heating & Air Sandy Springs operates under The Garrison Standard, which means the price you see in writing before we start is the price you pay. That’s been our approach since 2003, and it applies to every replacement we quote.
When You Need AC Replacement
Not every breakdown means replacement. But Sandy Springs summers in the mid-90s with matching humidity have a way of exposing systems that are limping rather than cooling. Here’s what tells us replacement is the right call:
- System age beyond 12 to 15 years. Most AC units in this climate give out between 12 and 15 years. If your outdoor unit is that old, a major repair like a compressor failure rarely pays for itself.
- R-22 refrigerant system. R-22 was phased out of production in 2020. If your system uses it, refrigerant costs have climbed sharply, and replacement with a modern unit is usually the better decision within two years.
- Rising electric bills without a change in usage. An aging unit loses efficiency gradually. When the outdoor coil is worn and the compressor is weak, the system runs longer to hit the same thermostat setting, and Georgia Power bills show it.
- Multiple repairs within 24 months. One repair is maintenance. Three repairs in two years is a signal the system is failing systemically, not incidentally.
- Uneven cooling between rooms. Homes in the Dunwoody Panhandle and along Riverside Drive often have original ductwork sized for older, less demanding systems. Persistent hot rooms can point to a system that is undersized or ductwork that needs correction during replacement.
- Outdoor unit runs constantly during summer afternoons. When a correctly sized system cannot cycle off during a 94-degree Sandy Springs afternoon, it is telling you it no longer has the capacity to do the job.
Our AC Replacement Process
We follow the same sequence on every replacement, from the first call through the final walkthrough. Here is exactly how it goes:
- Phone consultation and scheduling. When you call (478) 400-5908, a live person answers, 24/7. We document the issue, confirm the address, and set a two-hour arrival window. You get the technician’s name before they show up.
- Load calculation and home assessment. The technician measures your home’s square footage, ceiling heights, window exposure, insulation levels, and current ductwork condition. We run a Manual J load calculation so the new system is sized for your house, not guessed from the old unit’s label.
- Written replacement proposal. We walk through your options: system size, efficiency level, brand choices from manufacturers we’re factory-trained on including Carrier, Trane, and Daikin, and total installed cost. The price is in writing before any work begins, with no add-ons at the end of the job.
- Installation day. Our crew arrives in uniform, inside the stated window. We protect your floors, remove the old equipment, install the new system, and pressure-test the refrigerant lines. Replacement of the outdoor unit, indoor coil, and line set is standard on every full swap.
- Startup and system verification. We commission the new system: checking refrigerant charge, measuring temperature drop across the coil, verifying airflow at every register, and confirming thermostat operation.
- Walkthrough and written guarantee. Before we leave, we walk you through what was installed, how to operate it, and maintenance to extend its life. You receive a written guarantee covering the full replacement, backed by the 365-Day Done Right Promise. If anything is not right within that year, we return at no charge.
AC Replacement Pricing in Sandy Springs
Here are what we see as realistic ranges for complete AC replacements in the Sandy Springs market. These are installed prices including equipment, labor, refrigerant, and disposal of the old unit:
- 1,500 to 2,000 sq ft home, 3-ton system: $7,500 to $9,500 for a standard-efficiency unit; $10,000 to $12,500 for a high-efficiency unit with a variable-speed air handler.
- 2,000 to 2,800 sq ft home, 4-ton system: $8,500 to $11,000 for standard efficiency; $11,500 to $14,500 for high efficiency.
- 2,800 to 3,500 sq ft home, 5-ton system: $9,500 to $12,500 for standard efficiency; $12,500 to $16,000 for high efficiency with zoning controls.
- Ductwork modification or partial replacement: Adds $1,500 to $4,000 depending on scope. Homes with original 1980s and 1990s ductwork on the east side of GA-400 often need this.
What moves the number: system size, efficiency rating (SEER2), brand selection, whether the indoor coil and furnace need replacement to match, and access difficulty. A crawlspace install in a Mount Vernon Woods home takes longer than a closet air handler in a Riverside Drive condo. Estimates are free, and yes, the price we quote is the price on the invoice. No fuel surcharge, no miscellaneous line item added at the end.
What Affects the Cost Most
The biggest driver is system size, which is set by your home’s load calculation, not by what was there before. The second is efficiency. A 15 SEER2 unit costs less upfront than a 19 SEER2 variable-speed unit but uses more electricity over its life. The third is accessibility: a rooftop unit or a yard with tight fence access adds labor time. We explain all of this in the written proposal before you commit.
Equipment We Recommend and Service
Dalton Heating & Air Sandy Springs is factory-trained on nine major residential HVAC brands. For replacement work in this market, we commonly recommend systems from Carrier, Trane, and Bryant, based on your budget and cooling demands. A Bryant two-stage unit hits a strong middle ground between upfront cost and summer runtime efficiency. A Carrier variable-speed system works well for larger homes with uneven cooling. We also service and install American Standard and Daikin units regularly, and our technicians carry the training to work on all nine brands without subcontracted support.
FAQs – AC Replacement
How much does AC replacement cost in Sandy Springs?
Most complete AC replacements in Sandy Springs run $7,500 to $14,000 installed. The spread depends on home size, efficiency rating, brand, and whether ductwork needs work. Call (478) 400-5908 for a written quote. Estimates are free and the number we quote is the number you pay.
Is it cheaper to repair or replace my AC in Sandy Springs?
For systems under 10 years old with a single failed part, repair usually costs less ($150 to $450 for most component replacements). For systems over 12 years old with a compressor failure or coil failure, replacement is the cheaper path over a three-year window. We will show you both numbers in writing and let you decide.
Can you replace my AC in one day?
Yes, a standard outdoor unit and indoor coil swap is a one-day job for our crew. When we need to modify ductwork, relocate equipment, or install zoning controls, expect two days. We confirm the timeline in the written proposal before any work begins.
Will you haul away my old AC unit?
Yes, removal and disposal of the old equipment is included in every replacement quote. We handle refrigerant recovery and equipment recycling per EPA requirements, and we leave the equipment area clean before we leave.
What size AC system do I need for my Sandy Springs home?
The correct size is determined by a Manual J load calculation using your home’s square footage, insulation, window area, and ceiling height. Most single-story Sandy Springs homes between 1,800 and 2,200 square feet are served by a 3- to 3.5-ton system, but we confirm that with measurement, not guesswork. Oversized systems short-cycle, which raises humidity and shortens equipment life.
