# AC Replacement in Georgia | New Central Air Costs > AC replacement in Georgia: when it makes sense, what a new central AC costs, federal efficiency minimums, sizing, the refrigerant transition, and how to reach a participating contractor. URL: https://georgiahvacrepair.us/ac-replacement/ Georgia HVAC Repair is an independent referral service that connects Georgia homeowners with participating independent HVAC contractors, including for system replacement. Not every participating contractor installs new systems, so confirm when you're connected. This page explains what goes into an AC replacement and how to compare quotes. ## When replacement makes sense ENERGY STAR suggests considering replacement if your air conditioner or heat pump is more than 10 years old or needs frequent repairs, and says properly installed ENERGY STAR equipment can save up to 20% on heating and cooling costs ([ENERGY STAR](https://www.energystar.gov/saveathome/heating-cooling/replace)). A major repair, like a compressor or coil, on an older system, or a refrigerant leak in an R-22 system, are common tipping points. Our [repair or replace calculator](https://georgiahvacrepair.us/ac-repair-or-replace-calculator/) lays out the factors for your system. ## Efficiency rules in Georgia Georgia is in the Department of Energy's Southeast region. Since January 1, 2023, new split-system central air conditioners under 45,000 BTU (about 3.75 tons) must meet at least **14.3 SEER2** here, and new split-system heat pumps must meet 14.3 SEER2 nationwide ([U.S. Department of Energy](https://www1.eere.energy.gov/buildings/appliance_standards/pdfs/2023_CAC_Standards_FAQ_10-5-2022_Final.pdf)). Higher-efficiency systems cost more up front and less to run. ## Refrigerant is changing Older systems used R-22, which hasn't been produced in the U.S. since 2020 ([EPA](https://www.epa.gov/ods-phaseout/homeowners-and-consumers-frequently-asked-questions)). Most systems installed in recent years use R-410A, and new systems are moving to lower-global-warming refrigerants such as R-454B and R-32 under EPA rules that were revised in 2026. Ask each contractor which refrigerant the quoted system uses and how that affects future service. ## Sizing matters A bigger system isn't better. An oversized AC cools quickly but shuts off before it removes humidity, leaving a Georgia home cold and clammy, and it short cycles. Proper sizing uses a load calculation (Manual J) based on the home's size, insulation, windows, and orientation, not just the size of the old unit. Ask whether the contractor does one. ## Signs it may be time to replace - The system is more than 10 years old and needs a major repair - An R-22 system has a refrigerant leak - Repairs in multiple recent seasons - Rising power bills and uneven comfort - The house never feels dry in summer ## What AC replacement costs HomeAdvisor puts central AC installation at **$3,887–$8,073**, averaging about **$5,978** ([HomeAdvisor](https://www.homeadvisor.com/cost/heating-and-cooling/install-an-ac-unit/)). The unit alone runs roughly $2,900–$9,000 depending on size and efficiency. - System size (tonnage) and efficiency (SEER2) - Whether the indoor coil, air handler, or furnace is replaced too - Ductwork changes - Permits and electrical updates - Brand and warranty ## How to compare replacement quotes 1. **Get two or three written quotes** from licensed contractors. 2. **Compare the same thing:** size, SEER2 rating, whether the indoor coil is included, and the refrigerant. 3. **Ask about a load calculation** instead of matching the old unit's size. 4. **Ask who pulls the permit**; replacements generally require one. 5. **Get the warranty terms** for equipment and labor in writing. ## Questions to ask the contractor - Do you hold a current Georgia conditioned air contractor license? - What's the diagnostic fee, and is it credited toward the repair? - Will you give me the diagnosis and price in writing before you start? - Did you do a load calculation, and what size does it call for? - Does the quote include a matched indoor coil or air handler? - Which refrigerant does this system use? - Who pulls the permit, and is it included? ## FAQ **How much does a new central AC cost in Georgia?** HomeAdvisor puts central AC installation at $3,887–$8,073, averaging about $5,978. Size, efficiency, indoor equipment, ductwork, and permits all change the price. Get written quotes from licensed contractors. **What SEER2 rating is required in Georgia?** Since January 1, 2023, new split-system central ACs under 45,000 BTU sold in the Southeast region, including Georgia, must be at least 14.3 SEER2, per the U.S. Department of Energy. Split-system heat pumps must be at least 14.3 SEER2 nationwide. **Should I replace my AC and furnace together?** Often, if both are older, because the indoor coil sits on the furnace and matched systems perform best. A contractor can tell you whether your furnace has useful life left. **Does Georgia HVAC Repair do the work?** No. Georgia HVAC Repair is an independent referral service.
