How Much Does It Cost to Replace Central AC in Atlanta, GA? (2025 Guide)

Average Air Conditioning Replacement Cost in Atlanta

The summer heat in Atlanta is intense, making air conditioning a must-have. If your system breaks, replacing it can be an expensive but necessary project. The cost to replace central air conditioning in Atlanta typically ranges between $4,200 and $8,500, with an average cost of $6,000. This includes the price of the unit itself and installation.

Atlanta homeowners may find that their AC replacement costs are a bit lower than those in other hot climates like Phoenix or Miami due to the city’s more temperate climate, though the humidity still makes air conditioning a necessity.

For comparison, the national average for central AC replacement is around $4,500 to $8,000, making Atlanta’s prices fairly competitive. However, costs may be higher than this national range if your home is larger or requires more specialized equipment.

What Impacts the Cost of a New Air Conditioning Unit in Atlanta?

Several key factors can influence the cost of your central AC replacement in Atlanta. These include:

1. How Big Is Your Home? Larger homes require more powerful units to cool effectively. So the bigger your home, the higher the tonnage (capacity) needed, which will increase both the unit cost and the installation price. Most homes in Atlanta require three to five-ton systems depending on the size of the home. Larger homes may need higher tonnage, while smaller homes could get away with a smaller unit.
2. What SEER Rating Will You Choose? The Seasonal Energy Efficiency Ratio (SEER) is a key factor in determining the efficiency of an AC system. In Atlanta, homeowners should aim for a unit with a SEER rating of at least 16 for optimal energy efficiency. Higher-rated systems, such as those with 20 SEER or higher, will save you more on energy bills long-term but come at a higher upfront cost.
3. Do You Already Have Ductwork and Is It in Good Shape? If your existing ductwork needs to be repaired or replaced, the installation cost can rise. Homes with difficult-to-access spaces or outdated duct systems will see higher labor costs.
4. Which Brand and Model Will You Buy? Different brands offer varying prices and performance levels. In Atlanta, you will need to choose a brand that produces durable, efficient air conditioners.
5. Labor Costs: Labor costs can vary depending on the complexity of the installation. Technicians in Atlanta generally charge between $75 and $100 per hour, which is slightly higher than the national average due to the hot and humid summer months driving demand for services.

How Do I Estimate My AC Replacement Cost?

To estimate the cost of air conditioning replacement for a home in Atlanta, we recommend you look at price by square foot as well as unit type.

Home Square Footage and Cost

As we outline above and as you doubtlessly assumed, the bigger the home, the most expensive your unit and installation costs will be. However, you should also consider how many stories your home is. The table below shows cost for single-story homes; multi-story homes can see prices increase from here.

How Unit Type Impacts Cost

For a hot, humid city like Atlanta, you will be choosing between two general unit types, briefly outlined below.

• Standard AC Units: These units are typically 14-16 SEER and are suitable for most homes in Atlanta. The cost ranges from $3,500 to $6,500.
• High-Efficiency Units: If you want to reduce energy consumption and save on utility bills, opt for a 20 SEER or higher unit. Expect to pay between $6,000 and $8,500 for these models.

Tips to Save on System and Installation Cost

Here are some tips for homeowners in Atlanta to save on air conditioning replacement costs:

1. Get Multiple Quotes: You will find this advice across our website for every single home improvement project. Always get at least three quotes to find the best price, and don’t be afraid to ask questions about how your quote breaks down!
2. Take Advantage of Seasonal Discounts: HVAC companies often offer discounts in the spring and fall, as these are typically off-peak seasons for AC replacement.
3. Look Up Brand and Installer Promotions: Sometimes the air conditioning brand itself (for example, Carrier or Rheem) will offer discounts in your area. Other times, the installer (that will be the local contractor you hire to order and install your unit) will have promotions of their own. You can typically find this info on their websites, but absolutely ask any contractors you get a quote from if they are offering any specials or discounts.
4. Check for Rebates: Georgia Power offers rebates for upgrading to energy-efficient HVAC systems, so make sure to check their website for available incentives.
