HVAC Replacement Cost in Georgia: Installed Prices by SEER, 2027
Adjust your home size & electric cost in Georgia
Start with the house: 2,260 sq. ft. is the GA norm, and at that size the load math points to a 4-ton system, about 48,000 BTU. Installed with labor and parts, a 16 SEER system costs $10,450 to $12,600 in GA. That is the efficiency level where purchase price and power bills balance out best in this state.
Zone 5 weather gives Georgia hot summers, with highs averaging 92.5°F. Our model counts about 14.3 hours of daily run time across a 143-day season, so a 16 SEER unit uses about 6,748 kWh, roughly $1,340 of electricity a year.
These prices cover a single central system on existing ducts. Split-zone homes and ductless setups price differently.
What a New Central AC Costs in Georgia
Each row is the same 4-ton job in GA; only the efficiency changes. Watch the running-cost column: it shrinks as the price climbs.
| 4-ton system | Installed | Equipment | Power / season | Cooling / yr |
|---|---|---|---|---|
| 14 SEER | $8,370 – $10,090 | $5,220 | 7,625 kWh | $1,520 |
| 16 SEER | $10,450 – $12,600 | $6,470 | 6,748 kWh | $1,340 |
| 18 SEER | $15,970 – $19,250 | $9,760 | 6,067 kWh | $1,210 |
| 20 SEER | $21,920 – $26,420 | $13,300 | 5,521 kWh | $1,100 |
In GA, the realistic starting point is 16 SEER: federal rules for the southern region keep 14 SEER units off new installs. Expect $10,450 to $12,600 for 16 SEER, about $6,470 of it equipment, and 6,748 kWh a season. If the furnace is old too, run the heat pump calculator before you decide.
Local Prices Across Georgia
Big-city bids run a little higher than rural ones. The table adjusts the GA 16 SEER range for each major city:
16 SEER central AC, installed
- Atlantapop. 511,000$10,820 – $13,040
- Columbuspop. 203,000$10,680 – $12,880
- Augustapop. 201,000$10,680 – $12,870
- Maconpop. 157,000$10,640 – $12,830
- Savannahpop. 148,000$10,640 – $12,820
City figures adjust the statewide range for population and metro area, never by more than ±6%.
Georgia Electric Rates and Your AC's Running Cost
Electricity in Georgia costs $0.198/kWh right now, 9% below the national average of $0.217. Over the past decade the GA rate rose about 2.54% a year. If that trend holds, power will cost near $0.25/kWh by 2036, and a 16 SEER unit will cost about $1,720 a year to run.
Each line is one SEER rating; touch or hover a year to read its dollar figures. The climb is the 2.54% yearly increase GA rates showed over ten years.
The first point applies GA's current rate to this season; every point after it adds another year of the 2.54% average increase. Dollar figures are rounded up to the next $10.
The space between the top and bottom lines is money an old unit burns every summer. Summed over ten seasons, it comes to about $11,580 between 9 and 16 SEER in GA.
Upgrade Payback Finder: Your Old AC vs a New One
Set the two menus: the system in your house now and the one you are weighing. The math uses a 4-ton unit at Georgia electric rates, $0.198/kWh and climbing 2.54% yearly.
| Installed price of the new system | $11,360 |
| Electricity saved, first year | $1,040 |
| Saved over 10 summers (rates rising) | $11,580 |
| Payback | 9.8 years |
| Net after 10 summers | +$220 |
Worth it: 9 to 16 SEER comes out $220 ahead after 10 summers in GA.
If the old unit still works, the full install price is the cost of the upgrade. If it has to be replaced anyway, the 14 SEER comparison table below is the better guide.
Old 9 SEER vs New 14-20 SEER in Georgia
| 9 SEER | 14 SEER | 16 SEER | 18 SEER | 20 SEER | |
|---|---|---|---|---|---|
| Installation Cost | - | $9,090 | $11,360 | $17,360 | $23,820 |
| Electric Usage / Yr | 11,949 kWh | 7,625 kWh | 6,748 kWh | 6,067 kWh | 5,521 kWh |
| Electric Cost / Yr | $2,370 | $1,520 | $1,340 | $1,210 | $1,100 |
| Energy Savings / Yr | - | $860 | $1,040 | $1,170 | $1,280 |
| Payback (Rates Rising) | - | 9.5 years | 9.8 years | 12.8 years | 15.5 years |
| 10-Year Net (Rates Rising) | - | $540 | $220 | -$4,270 | -$9,520 |
Net savings subtract the install price from ten seasons of lower bills. Best value in green. Note: 14 SEER rows are for comparison. New installs in GA must beat the regional efficiency minimum.
Verdict for GA: among the ratings you can legally install, 16 SEER is the cheapest to own over ten years ($26,380).
Total Cost to Own Each SEER in Georgia
Buy Price vs 10-Year Running Cost: Total Cost of Ownership in GA
Install price plus ten seasons of electricity at Georgia rates, growing 2.54% yearly, gives the real price of each system. Compare the total bars: the shortest one wins. Hover or tap for the breakdown.
After 10 years, 16 SEER is the cheapest system to own in Georgia: $26,380 all-in ($11,360 installed + $15,030 of electricity).
How the electricity bar is built: this season at today's GA rate, then nine more seasons, each raised by the 2.54% yearly increase GA has averaged. Install is the typical price shown on this page. Every figure is rounded up to the next $10 separately, which can leave the parts $10 over the total. 14 SEER is left out: it is below the federal minimum for new central AC installs in Georgia.
During peak months, a 16 SEER system in GA uses about 1,416 kWh, near $290 at today's rate. An older, less efficient unit costs more for the same comfort.
Is 18 or 20 SEER Worth It in Georgia?
An 18 SEER system costs $15,970 to $19,250 installed in GA. It trims the season to about 6,067 kWh and runs longer at low speed, which also evens out room temperatures.
Shopping in the Atlanta area? An 18 SEER install there runs about $16,530 to $19,920.
For 20+ SEER, plan on $21,920 to $26,420 at GA prices. A Lennox XP20 can reach $32,160; the SL25XPV starts around $42,400.
Tip: sister brands can save real money. Armstrong Air is owned by Lennox's parent company and usually costs less for a similar unit.
Compared on electricity alone, 20 SEER wins: 5,521 kWh a season, a 28% cut from 14 SEER and 54% from 9 SEER. At GA rates that saving does not cover the premium within ten years.
How Georgia's Climate Shapes Your AC
Zone 5 and hot summers mean a larger-than-average system here. Other parts of GA weather matter as much as size.
Climate zones run from 1 (cool) to 5 (hot); Georgia is in Zone 5.
Humidity. An AC removes moisture as well as heat. A unit sized too big cools the air fast, shuts off and leaves the house damp, so insist on a Manual J load calculation and consider a two-stage or variable-speed model that runs long at low speed.
High-wind storms. Ask for hurricane straps on the condenser and a surge protector at the disconnect. Both are small line items next to a ruined compressor.
Severe storms. Thunderstorms and high winds throw debris and cut power. Secure the outdoor unit, keep loose items away from it, and add surge protection.
When to buy: late fall and winter are the slow months for GA installers, so scheduling is easier and you are not shopping during an emergency.

How SEER Ratings Work
Think of SEER as miles per gallon for cooling: BTUs of heat removed per watt-hour of power, averaged over a season.
For the 48,000 BTU system this page prices, 16 SEER works out to 3,000 W of compressor draw (48,000 ÷ 16). The fan adds about 300 W, for roughly 3.3 kW in total.
Shopping tip: equipment rated under the newer rules carries a SEER2 number, which reads lower than old-style SEER for the same unit.
Use the table for a first guess at size (Georgia: Zone 5):
| AC Size | ZONE 1 | ZONE 2 | ZONE 3 | ZONE 4 | ZONE 5 |
|---|---|---|---|---|---|
| 1.5 Ton | 700-1100 s.f. | 700-1050 s.f. | 500-1000 s.f. | 500-950 s.f. | 500-900 s.f. |
| 2 Ton | 1101-1400 s.f. | 1051-1350 s.f. | 1001-1300 s.f. | 951-1250 s.f. | 901-1200 s.f. |
| 2.5 Ton | 1401-1650 s.f. | 1351-1500 s.f. | 1301-1500 s.f. | 1251-1550 s.f. | 1201-1500 s.f. |
| 3 Ton | 1651-2100 s.f. | 1601-2000 s.f. | 1601-1900 s.f. | 1501-1850 s.f. | 1501-1800 s.f. |
| 3.5 Ton | 2101-2300 s.f. | 2001-2250 s.f. | 1901-2200 s.f. | 1851-2150 s.f. | 1801-2100 s.f. |
| 4 Ton | 2301-2700 s.f. | 2251-2700 s.f. | 2201-2500 s.f. | 2151-2500 s.f. | 2101-2400 s.f. |
| 5 Ton | 2701-3300 s.f. | 2751-3300 s.f. | 2601-3200 s.f. | 2501-3100 s.f. | 2401-3000 s.f. |
Ask for a written Manual J. Bigger is not better: an oversized system costs more and controls humidity worse.
