When summer temperatures soar into triple digits, staying cool isn’t just a comfort—it’s a necessity. Unfortunately, running the air conditioner around the clock can put a serious dent in your wallet. The good news? There are smart, simple strategies homeowners can use to lower their energy bills without sacrificing comfort. Here are some of the most effective ways to beat the heat and save money during a heatwave.
Use a Programmable or Smart Thermostat
One of the easiest and most impactful changes you can make is installing a programmable or smart thermostat. Set it to increase the temperature when you’re away from home and cool down shortly before you return. Smart thermostats go a step further by learning your habits and adjusting automatically to optimize both comfort and energy savings.
Seal Leaks and Insulate
Don’t let your cold air escape! Check for drafts around windows, doors, and ductwork. Use weatherstripping, caulk, or insulation to seal any leaks. Proper insulation in your attic and walls also helps keep cool air in and hot air out, reducing the strain on your HVAC system.
Use Ceiling Fans Efficiently
Ceiling fans don’t cool the air—they move it. But when used correctly, they can make a room feel 4–6 degrees cooler. Be sure your fan is spinning counterclockwise in the summer to push air downward.
Avoid Heat-Generating Appliances During the Day
Ovens, stoves, and even clothes dryers add unnecessary heat to your home during the hottest parts of the day. Cook outside on the grill or use a microwave or slow cooker. Try doing laundry and running the dishwasher early in the morning or late at night when it’s cooler.
Close Blinds and Curtains
Sunlight streaming through windows can significantly increase indoor temperatures. Close blinds, shades, or curtains during the hottest hours of the day—especially on south- and west-facing windows. Blackout curtains or reflective window film can provide even greater heat reduction.
Schedule an AC Tune-Up
Your air conditioning system works hard during a heatwave, so make sure it’s running efficiently. A professional tune-up can clean coils, check refrigerant levels, and fix any issues before they become costly problems. Maintain clean and functional filters to ensure proper airflow is available.
Consider Energy-Efficient Upgrades
If your HVAC system or appliances are more than 10–15 years old, they might be costing you more than you think. Upgrading to ENERGY STAR-rated equipment can drastically cut energy usage. Many utilities and local governments offer rebates or incentives to offset the cost.
Use Utility Rebates and Time-of-Use Plans
Check with your utility provider to see if they offer incentives for energy-saving improvements or if they have time-of-use pricing. Shifting energy use to off-peak hours (typically nights and weekends) can result in noticeable savings.
