It usually happens at the worst possible moment. The AC gives out during a sticky August afternoon, or the furnace stops firing on the first cold night of the year. Then the quotes start coming in, and they can be thousands of dollars apart for what sounds like the same job.
At Maintenance Unlimited Heating & Cooling, we have been helping College Park, GA families through that exact situation since 2001. This guide breaks down what a new HVAC system really costs in Georgia in 2026, what drives the price up or down, and how to make sure you are comparing quotes fairly.
How Much Does a New HVAC System Cost in Georgia?
In 2026, a code-minimum central air system in Georgia typically costs about $3,750 to $14,100 installed, depending on size (2 to 5 tons). Replacing both the air conditioner and furnace in an average 2,000-square-foot home commonly runs $7,000 to $20,000. High-efficiency equipment, heat pumps, new ductwork, or electrical upgrades can push the total higher.
Nationally, homeowners are spending anywhere from roughly $5,000 to $28,000 for a full replacement this year. Georgia tends to land toward the lower-middle of that range because HVAC labor costs here run slightly below the national average.
Average HVAC Replacement Cost in Georgia by System Size
System size is measured in tons of cooling capacity, and it is one of the biggest factors in your price. Here are estimated installed ranges for code-minimum equipment in Georgia, published by HVAC-Cost:
| System Size | Estimated Installed Cost in Georgia |
| 2-ton | $3,750 – $8,000 |
| 2.5-ton | $4,250 – $8,950 |
| 3-ton | $4,700 – $10,350 |
| 3.5-ton | $5,150 – $11,300 |
| 4-ton | $5,650 – $12,700 |
| 5-ton | $6,600 – $14,100 |
For example, a 1,500-square-foot ranch home in College Park might need a 2.5- or 3-ton system, while a larger two-story house could need 4 or 5 tons, or even two separate systems. Square footage alone is not enough to size a system, though, which we cover below.
HVAC Installation Cost by System Type
The type of equipment you choose matters as much as the size. Carrier publishes these reference ranges for equipment plus standard installation:
- Central air conditioner: $3,000 – $15,000
- Gas furnace: $3,800 – $12,000
- Heat pump: $6,000 – $25,000
- Ductless mini-split: $2,000 – $10,500
These ranges should not simply be added together to price a combined system, since a paired AC-and-furnace replacement shares labor and installation work.
Central AC and Gas Furnace
This pairing is still the most common setup in Georgia homes. If your home already has natural gas service, a gas furnace paired with a new central AC is often the most straightforward and cost-effective replacement. If one unit is failing and the other is near the same age, replacing both together usually saves on labor and ensures the components are properly matched.
Heat Pumps
Georgia’s long, humid summers and short, mild winters make heat pumps an excellent fit. A heat pump handles both cooling and heating in one system and is the dominant electric heating choice across the state. Upfront costs are higher, but they can lower operating costs for homes without gas. Learn more about our heat pump installation in College Park, GA.
Ductless Mini-Splits
Ductless mini-splits are a smart option for additions, converted garages, sunrooms, or older homes without ductwork. Pricing depends heavily on how many indoor zones you need.
What Affects the Price of a New HVAC Unit in 2026
Two homes of the same size can receive very different quotes. Here is why.
Proper Sizing and Load Calculation
Bigger is not better. An oversized system short-cycles, wastes energy, and leaves your home feeling clammy, which is a real problem in Georgia’s humidity. An undersized system runs nonstop and still struggles on the hottest days. A reputable contractor calculates your home’s actual heating and cooling load, factoring in insulation, windows, layout, and sun exposure, rather than just matching your old unit.
SEER2 Efficiency Ratings
In the Southeast, new split-system air conditioners under 45,000 BTU/h must meet a minimum of 14.3 SEER2. Higher-efficiency, two-stage, and variable-speed systems cost more upfront but can lower monthly bills. With Georgia residential electricity averaging around 15.8 cents per kWh, that difference adds up over a system’s lifespan. Try our SEER calculator to estimate potential savings.
As an Amana featured dealer, we offer the Amana Lifetime Replacement Warranty on 16 SEER and above systems, which is worth factoring in when comparing long-term value.
Refrigerant Changes
The HVAC industry is moving away from older refrigerants to newer, lower-impact alternatives. That transition has raised equipment costs and can affect whether an older system is worth repairing. If your current system still uses R-22, which has been phased out, replacement is often the more practical choice.
Ductwork, Electrical, and Permits
The equipment is not always the only expense. Older homes may need duct sealing or replacement, an updated electrical panel, or a new thermostat. If your home needs new ductwork, costs can rise by about $3,000 or more.
Georgia also requires a permit for HVAC changeouts. The state adopted the 2024 International Mechanical Code with Georgia amendments, effective January 1, 2026, and local cities and counties handle permits and inspections. A licensed contractor should include permitting in your quote.
Georgia HVAC Rebates and Tax Credits in 2026
Incentives can trim your final cost, but the rules have changed this year.
- Federal tax credit: The federal Energy Efficient Home Improvement Credit does not apply to equipment placed in service after December 31, 2025. Do not count on the old $2,000 heat pump credit for a 2026 installation.
- Georgia Power Home Energy Improvement Program: Offers incentives such as up to $400 for duct sealing, up to $1,000 for converting to an air-source heat pump, and a Home Comfort Bundle of up to $1,250. These focus on upgrades and conversions rather than like-for-like swaps.
- Electric membership cooperatives (EMCs): Some co-ops, such as Cobb EMC, run their own HVAC rebates with separate requirements.
Your eligibility depends on which utility serves your electric meter, so confirm with your provider before installation. We are happy to help you sort out which programs may apply to your system.
How to Get an Accurate HVAC Quote in College Park, GA
A low quote is not always a good deal, and a high one is not always inflated. Use this checklist when comparing bids:
- Compare the same scope. Make sure each quote covers the same equipment, ductwork, electrical work, permits, and removal of the old unit.
- Ask for model numbers. Get exact equipment models, tonnage, and SEER2 ratings in writing.
- Separate the warranties. Know what the manufacturer warranty covers and what the installer’s labor warranty covers.
- Avoid emergency timing when possible. If your system is aging but still running, replacing it on your schedule gives you time to compare options.
- Ask about financing. Spreading the cost out can make a higher-efficiency system more manageable. See our HVAC financing options and current promotions.
Frequently Asked Questions
How long does an HVAC replacement take?
Most residential replacements are completed in a single day. Jobs involving new ductwork, electrical upgrades, or multiple systems may take longer.
How long does an HVAC system last in Georgia?
Air conditioners in our climate work hard for much of the year. Once a system reaches 12 to 15 years old, needs frequent repairs, or struggles to keep up, replacement is usually worth considering. Routine AC maintenance and heating maintenance help you get the most out of your equipment.
Should I replace my AC and furnace at the same time?
If both units are similar in age, replacing them together often saves on labor and ensures matched, efficient performance. If one is relatively new, replacing only the failed unit may make more sense. We will give you an honest recommendation either way.
Is it worth paying more for a high-efficiency system?
It depends on how long you plan to stay in your home and how much you run your system. In Georgia, where the cooling season is long, higher SEER2 equipment often pays back more of its premium than it would in milder climates.
Do I need a permit to replace my HVAC system in Georgia?
Yes. Georgia requires a permit for HVAC changeouts, issued by your local city or county. A licensed contractor should pull it for you.
