Atlanta has long hot days, high outdoor temperatures, and sticky humidity that makes the air feel warmer. Cooling costs can reach 40–50% of a summer electric bill, especially in older homes with weak insulation, ductwork leaks, or aging cooling equipment. Ragsdale Heating, Air, Plumbing & Electrical helps homeowners in Dallas, Loganville, and across georgia improve energy efficiency and save money.
Walk your house on a hot afternoon. Watch for a hot room over the garage, drafts around windows, warm floors upstairs, and exterior doors that leak cool air.
Check:
Small air leaks can have the same effect as leaving a door open, wasting energy in heating and cooling. Sealing air leaks around doors and windows reduces cooling load by stopping hot, humid outdoor air from entering. Proper attic insulation also matters: adding just 1 inch of insulation to an uninsulated wall can reduce heat loss in winter or heat gain in summer by 40-50 percent.
The U.S. Department of Energy recommends 78° Fahrenheit when you are home and awake, and 7° Fahrenheit higher when away from home to save energy. Every degree cooler can increase cooling costs by about 4%, so raising the thermostat a couple degrees at home can save at least 10% per year on your energy bill.
Do not set the thermostat below 72°F to cool faster. It only makes the system work harder and raises your power bill. A consistent temperature is better for comfort and efficiency.
A programmable thermostat or smart thermostat can save almost 15% in cooling costs by maintaining a consistent temperature and allowing scheduled adjustments. Try 78°F home, 83–85°F away, and 78–80°F at night with ceiling fans near the bed. Ragsdale can install and configure the switch.
Regular maintenance keeps your AC system running at peak performance, including changing air filters regularly, keeping the outdoor unit clean, and scheduling annual professional maintenance.
Dirty air filters, clogged coils, and low refrigerant restrict air, reduce efficiency, and force the cooling system to run longer. Changing air filters monthly during the summer, or at least every three months, is crucial because dirty filters restrict airflow and make the system work harder.
Keep the outdoor condenser clear of debris and maintain at least two feet of clearance on all sides. Annual spring service through Ragsdale’s Complete Comfort Maintenance membership helps protect equipment, improve energy savings, and reduce surprise costs.
Use caulk, door sweeps, and weather strip around windows and doors. These fixes help keep cool air inside and reduce heat gain. Ragsdale also offers insulation and air sealing service for deeper home energy improvements.
Ceiling fans should run counterclockwise in summer to push cool air downward, creating a wind-chill effect that can make you feel up to 4 degrees cooler. Using ceiling fans with a thermostat setting 2° Fahrenheit higher can reduce cooling costs by up to 14%.
Fans cool people, not rooms, so turn fans off when leaving a room. Ceiling fans do not lower temperature, but they help more people stay cool for less money.
High humidity can make temperatures feel significantly hotter, particularly in the summer. Aim for 45–55% indoor humidity. Musty smells, clammy air, condensation, and mold are telltale signs. Use bath and kitchen fans, and ask Ragsdale about dehumidifiers or energy efficient cooling equipment if humidity stays high.
Close blinds or blackout curtains during peak sunlight hours to block significant radiant heat. Reflective solar window film can bounce the sun's thermal rays back outside. Planting shade trees on the south and west sides of homes provides natural cooling benefits, and strategic landscaping can save up to 25% of typical household energy use by reducing solar heat absorption.
Run ovens, dryers, dishwashers, clothes washers, and the water heater early morning or late evening. Running heavy appliances during peak energy hours can increase cooling costs. Running major appliances during off-peak hours can reduce electricity costs because energy costs are higher during peak demand. Peak demand hours are often 2 p.m. to 7 p.m., while from June through September, peak hours for electricity usage are typically 4 p.m. to 9 p.m. Check georgia power options, use cold water for laundry, and switch to LEDs.
Old cooling equipment cannot always be rescued. If your ac is 10–15 years old, breaks often, leaves hot spots, or your cooling bills rise with the same use, replacement may cost less over time. Older Atlanta systems may be SEER 10–12, while modern high-efficiency systems often reach 15–20+. Ragsdale installs efficient air conditioning and heat pump systems with financing and 15-year parts and labor warranties.
DIY steps help, but the biggest energy savings often come from proper diagnostics. Ragsdale provides AC tune-ups, duct repair, insulation, air sealing, thermostat installation, and cooling system replacement, backed by 24-hour customer service and a 100% satisfaction guarantee. Contact Ragsdale to lower your home energy, cooling bills, and summer cooling costs.
About 76–78°F works for many homeowners. Raise it when away, and use ceiling fans for comfort.
Schedule professional service once a year in spring. Check filters monthly in summer and replace them every 30–60 days during heavy use.
Turn it up several degrees when away. Do not shut it fully off on very hot days, or the unit may fight built-up heat and humidity later.
Yes, indirectly. They make you feel cooler, so you can raise the thermostat and reduce costs.
Feel around doors and windows, look for dust trails, and note rooms with uneven temperature. Ragsdale can inspect hidden leaks.
The 20 rule often means keeping indoor temperature about 20°F lower than extreme outdoor heat, not forcing the AC to impossible settings.
Yes. Since every degree cooler can add about 4% to cooling costs, 72°F is cheaper than 70°F because the AC runs less.
Raise the thermostat 2°F, run appliances off peak, close blinds, and replace filters. Those simple steps can lower your electric bill quickly.
