If you’ve opened a Georgia Power bill in July and done a double-take, you’re not alone. According to Georgia Power’s own data, the average Atlanta-area summer bill runs around $266 in July, compared to roughly $171 averaged across the full year. For some households, especially those with older systems, larger homes, or higher usage, summer bills can climb much higher.
The good news is that a large portion of that spike is preventable, and most of the fixes don’t require spending a lot of money. This guide breaks down exactly why your bill jumps in summer and what you can do to lower your Atlanta energy bill before next season hits.
Why Georgia Power Bills Are Higher in Summer
The spike isn’t just because it’s hot. There are several compounding reasons why summer bills hit harder in Georgia than in many other states.
Tiered Summer Rates
Georgia Power’s standard residential plan uses tiered pricing in summer months (June through September). You pay one rate for the first 650 kilowatt-hours you use in a month, a higher rate between 650 and 1,000 kilowatt-hours, and a higher rate still above 1,000 kilowatt-hours. The more your AC runs, the higher the rate tier you reach, and the faster each additional kilowatt-hour costs you.
Georgia Power also offers optional time-of-use rate plans, such as Smart Usage and Nights and Weekends, where rates are specifically higher from 2 p.m. to 7 p.m. on summer weekdays (June through September). These plans can save money if you’re able to shift appliance use to off-peak hours, but they require actively changing your habits and signing a one-year contract. Most customers remain on the standard tiered plan, where total monthly usage is the main cost driver, not the time of day.
Rising Rates Overall
Georgia Power customers have seen six rate increases approved by the Georgia Public Service Commission in recent years, with the average residential customer paying roughly $43 more per month than in 2022. In July 2025, the Georgia PSC unanimously approved a plan to freeze base rates through at least 2028, which should provide some stability. But rates are still meaningfully higher than they were just a few years ago, and summer usage amplifies that difference.
Atlanta’s Climate
Atlanta summers are long, hot, and humid. Average July temperatures in Atlanta run around 80 to 84 degrees Fahrenheit, and the humidity makes it feel hotter. Your AC has to run longer and work harder to overcome outdoor heat gain, especially during afternoon hours when temperatures peak. The longer it runs, the more kilowatt-hours it burns.
How Much of Your Summer Bill Is Actually the AC?
Cooling accounts for the largest single share of home energy use in Georgia during summer months. The U.S. Energy Information Administration estimates that air conditioning represents about 17 percent of the average U.S. home’s annual energy use, and in hot Southern states like Georgia, that share is higher. In peak summer months, your AC is almost certainly the dominant driver of your bill.
That also means it’s the biggest lever you have. Small improvements to how your system runs, how you set your thermostat, and how well your home is sealed can add up to meaningful savings on your Georgia Power bill over the course of a summer.
Thermostat Settings: The Simplest Thing You Can Do
The U.S. Department of Energy recommends setting your thermostat to 78 degrees Fahrenheit when you’re home during summer. Every degree you lower the thermostat below that point can add up to 3 percent to your cooling costs, according to DOE guidance. That adds up fast.
The bigger opportunity is when you’re away. The DOE notes that raising your thermostat by 7 to 10 degrees for at least 8 hours a day (when you’re at work, for example) can save up to 10 percent on your annual cooling and heating costs. That’s a meaningful reduction without touching your equipment at all.
| One common mistake: setting your thermostat to 65 degrees when you get home hoping it’ll cool faster. Your system cools at the same rate regardless of the setpoint. All you’re doing is making it run longer. Set it to your target temperature and let it work. |
Setback Schedule That Actually Works in Atlanta
- Home, awake: 78 degrees (DOE recommended baseline)
- Away from home: 85 to 88 degrees. Don’t go higher than that in Atlanta summers. Your system needs to run enough to control humidity, and letting a humid home bake all day creates other problems.
- Sleeping: 78 to 80 degrees. Ceiling fans make a real difference here. They don’t cool the air, but they make 80 degrees feel more comfortable by moving air across your skin.
Smart Thermostats: Set It and Actually Forget It
A programmable or smart thermostat makes the setback schedule above automatic. You set it once and it handles the rest. You’re not relying on remembering to adjust it before you leave or when you go to bed.
Smart thermostats like the Ecobee or Google Nest go further. They learn your schedule, factor in local weather forecasts, and make real-time adjustments. They can also show you your usage data, which helps you spot patterns you’d otherwise miss.

Your AC System: The Biggest Variable on Your Bill
Here’s something most homeowners don’t realize: two homes the same size, with the same thermostat settings and similar habits, can have dramatically different energy bills based on the age and condition of the AC system alone.
Older Systems Cost More to Run
Air conditioners are rated for efficiency using a SEER2 number (Seasonal Energy Efficiency Ratio). The higher the SEER2, the more cooling you get per kilowatt-hour of electricity. Systems installed 10 or more years ago often operate at SEER ratings of 10 to 13. New systems must meet a minimum SEER2 of 14.3 in Georgia (the Southeast region standard), and high-efficiency systems reach 20 SEER2 or higher.
According to the U.S. Department of Energy, replacing a 10-year-old system with a new, properly installed high-efficiency model can reduce cooling costs by 20 to 40 percent. On a $266 July bill, that’s a real number worth paying attention to.
| A Simple Way to Look at SEER Savings Divide your old system’s SEER by your new system’s SEER2 to estimate the energy ratio. A system going from SEER 10 to SEER2 18 uses roughly 55 percent of the electricity the old one used, a 45 percent reduction in cooling energy costs. Your actual savings will vary based on usage and local rates. |
Systems Lose Efficiency as They Age
Even a system that was efficient when new loses performance over time. Research published through the American Council for an Energy-Efficient Economy found that AC systems degrade at roughly 3 to 4 percent per year on average, with coil fouling and refrigerant loss being the primary causes. A system that hasn’t been maintained can lose a significant portion of its rated efficiency over its lifespan.
That degradation shows up on your bill. The system runs longer to achieve the same cooling. It uses more electricity per hour. And it wears out faster because it’s working harder than it should.
Oversized Systems Are Inefficient Too
A system that’s too large for your home will cool quickly and shut off before it’s properly dehumidified the air. You end up with a home that feels clammy even at the right temperature, and the system short-cycles (starts and stops repeatedly), which wastes energy and causes more wear than steady operation. If your home feels muggy even with the AC running well, oversizing may be the issue.
Maintenance: What Gets Ignored, Gets Expensive
A well-maintained AC runs more efficiently, lasts longer, and costs less to operate. Most of the maintenance that makes a difference isn’t complicated or expensive.
- Change your air filter regularly. A clogged filter restricts airflow and forces your system to work harder. During Atlanta summers, check it every month. This is the single easiest thing you can do.
- Keep your outdoor condenser unit clear. The condenser releases heat from your home to the outside air. If it’s blocked by shrubs, debris, or a fence on all sides, it can’t do that job efficiently. Give it at least two feet of clearance on all sides. Keep grass and debris off the coil.
- Schedule a professional tune-up once a year. A Berry Good technician will check refrigerant levels, clean the evaporator and condenser coils, inspect electrical connections, and verify the system is operating at rated efficiency. A dirty coil alone can reduce efficiency by 5 to 15 percent.
- Clear the condensate drain line. When this line clogs, water backs up and the system often shuts down as a safety measure. A simple flush once a year keeps it clear.
- Check your duct sealing. Leaky ducts can lose 20 to 30 percent of cooled air to unconditioned attic or crawl space before it reaches your living areas, according to the DOE. If your home has uneven temperatures or consistently high bills, duct leakage is worth investigating.
| Berry Good’s preventive maintenance plan covers annual inspections, coil cleaning, refrigerant checks, and the kind of detailed tune-up that keeps your system running at its rated efficiency. It’s the most cost-effective thing most Atlanta homeowners can do to lower their summer energy bills. |
Home Improvements That Reduce AC Load
Your AC bill is partly determined by how hard your system has to work, which is determined by how much heat enters your home. Reducing that heat load means your AC runs less, even with the same thermostat setting.
- Attic insulation: Atlanta’s hot attics transfer heat into your living space all day. Proper insulation (R-38 or higher is commonly recommended for the Southeast) significantly reduces that gain.
- Sealing air leaks: Gaps around windows, doors, recessed lights, and attic hatches let hot humid air into your home. Weatherstripping and caulk are low-cost fixes with real payoff.
- Window coverings: Closing blinds or curtains on south and west-facing windows during peak afternoon hours can meaningfully reduce the heat your AC has to overcome.
- Ceiling fans: Running ceiling fans on the counterclockwise setting in summer creates a wind chill effect. You can raise your thermostat setpoint by a few degrees without noticing a difference in comfort. Turn fans off when you leave the room. They cool people, not spaces.
When Your Bill Jumps and Nothing Has Changed
If your bill spikes significantly from one summer to the next without obvious changes in behavior, it usually points to one of a few things:
- A refrigerant leak. Low refrigerant forces your compressor to run constantly without effectively cooling the space. Your system works harder, your home stays warm, and your bill climbs.
- A failing capacitor or contactor. These are common failure points in older systems. When they start going, the system struggles to start or run properly.
- A dirty evaporator or condenser coil. Even a thin layer of buildup reduces heat transfer significantly. This is exactly what a professional tune-up catches.
- Duct leaks that have worsened. Ductwork in unconditioned attics can deteriorate over time, and a connection that was slightly leaky can become significantly leaky.
If your bill went up and you haven’t changed anything, call Berry Good. A diagnostic visit often identifies the cause quickly, and many of the fixes are straightforward.
What to Do Right Now
You don’t have to overhaul everything at once. Start with what costs nothing, then work your way up.
- Adjust your thermostat schedule today. Set it to 78 when home, 85 to 88 when away, and program it to return to comfort before you get back.
- Check your air filter. If it’s gray and clogged, replace it. You’ll feel a difference in airflow within hours.
- Clear around your outdoor condenser unit. Remove any debris, trim back overgrowth, and make sure airflow isn’t blocked.
- Schedule a tune-up if you haven’t had one this year. A Berry Good technician can identify efficiency losses you’d never find on your own.
- If your system is 10 or more years old, ask Berry Good about efficiency upgrade options. The math on a new high-efficiency system often works in your favor, especially given current Georgia Power rates.

Frequently Asked Questions
MERV stands for Minimum Efficiency Reporting Value, a standardized scale developed by ASHRAE to measure how effectively an air filter captures airborne particles. The scale runs from 1 to 16, with higher numbers capturing smaller particles more efficiently. For most Atlanta homes, a MERV 8 to MERV 13 filter is appropriate, depending on the system and household conditions.
MERV 11 is the most practical starting point for most Atlanta households. It handles pollen, pet dander, dust mite particles, and mold spores without the airflow concerns of higher ratings. If someone in your home has asthma or serious allergies, MERV 13 is worth considering, but verify your system can handle it first. For a healthy home with no pets and no allergy concerns, MERV 8 is adequate.
Yes, it can. A filter with too high a MERV rating for your system restricts airflow, causing the blower to work harder, efficiency to drop, and in serious cases the evaporator coil to ice over or the motor to fail prematurely. This is especially true with 1-inch MERV 13 filters in older systems. Always check your system’s owner manual for a maximum MERV recommendation before upgrading.
More often than the package suggests for most of the year. Atlanta systems run long cooling seasons and face heavy pollen loads from February through October. A 1-inch pleated filter should be checked monthly and changed every 30 to 90 days depending on pets, occupants, and season. During peak pollen months, monthly changes are often necessary. A 4 to 5-inch media filter typically lasts 6 to 12 months.
Yes. According to the U.S. Department of Energy, a clogged air filter can cause your HVAC system to use 5 to 15 percent more energy. The filter restricts airflow and forces the system to run longer and work harder to reach your thermostat setting. In Atlanta summers when the AC runs almost continuously, that energy waste accumulates fast.
Thickness determines surface area, which affects how long the filter lasts and how much resistance it creates. A 1-inch filter has less surface area and clogs faster, requiring replacement every 1 to 3 months. A 4 to 5-inch media filter has far more surface area, lasts 6 to 12 months, and handles higher MERV ratings with less airflow restriction. The thicker option requires a compatible filter cabinet in your ductwork, which Berry Good can install.
MERV-A is a supplemental rating defined in Appendix J of ASHRAE Standard 52.2. It tests filter performance after the electrostatic charge in the filter media has been partially removed, simulating real-world aging. Some filters with electrostatic charge perform well when new but drop in efficiency over time as the charge fades. A filter rated MERV 11 might carry a MERV-A of 8, meaning its real-world sustained performance is closer to a standard MERV 8. When both ratings are listed, MERV-A gives you a better picture of long-term performance.
Not always, but it depends on the system and the filter format. ASHRAE and the EPA recommend MERV 13 as a target for homes prioritizing air quality or managing health concerns like allergies, asthma, or infection control. It is not a universal minimum for all homes. The main issue is airflow restriction, particularly with 1-inch MERV 13 filters in older systems. A 4 to 5-inch MERV 13 media filter creates significantly less pressure drop than a 1-inch version at the same rating, making it a much safer choice for most residential systems. If you’re unsure whether your system can handle MERV 13, ask Berry Good before making the switch.
