This guide walks you through the top ways families are lowering their electric bills this summer—so you can relax, stay cool, and still save.

Optimize Your Cooling System for Maximum Efficiency

Staying cool isn’t just about cranking up the AC whenever you feel warm—it’s about getting the most from your cooling system without wasting energy. A few simple upgrades and habits can make a real impact on how much electricity your system uses. Here’s how to keep your air conditioner working smarter, not harder, so you save money all summer.

Schedule Annual Air Conditioner Maintenance

An annual tune-up is the key to a healthy air conditioner. When you schedule regular HVAC maintenance, you boost your system’s efficiency and cut down on utility costs. Clean filters, unclogged vents, and dust-free coils keep air flowing freely and prevent your unit from overworking.

• Energy Savings: Regular upkeep can help your system run up to 15% more efficiently.
• Longer Lifespan: Maintenance reduces wear and tear, helping you avoid expensive breakdowns.
• Immediate Impact: Dirty coils or filters make your AC use more power just to cool the same space.

A well-tended AC is like a clean car engine—it runs better and costs less to operate. For more details on yearly tune-ups and their impact, check out these 7 reasons HVAC maintenance is essential.

Install and Use a Programmable or Smart Thermostat

A programmable thermostat removes the guesswork from temperature control. With just a few taps, you set the AC to ease off while you’re at work or asleep, and ramp back up before you get home. Smart thermostats take things to the next level, using sensors and schedules to optimize comfort and savings automatically.

• Save $50 or more every year just by setting higher temperatures when you’re not home.
• Many smart thermostats let you join utility demand response programs, which help lower electric grid stress and sometimes provide rebates.
• These devices learn your routines, so you won’t have to remember to adjust the temperature yourself.

They give you control via your phone, making it easy to check and update settings on the go. For a deep look at how these controls work and their savings, see the ENERGY STAR guide to smart thermostats.

Upgrade to ENERGY STAR-Certified Cooling Appliances

If your AC is more than 10 years old, it’s probably using far more electricity than necessary. Upgrading to an ENERGY STAR-certified unit can cut your cooling costs right away.

• ENERGY STAR air conditioners use up to 15% less energy than standard models.
• Certified systems often run quieter and keep temperatures more consistent.
• You might even qualify for rebates or incentives from local utility companies.

Browse the official ENERGY STAR list of efficient products, including the latest in air conditioning technology. New units pay for themselves over time with lower monthly bills and reliable performance.

Simple upgrades and smart maintenance are the foundation of a more efficient—and less expensive—summer.

Keep Heat Out: Insulation and Air Sealing Solutions

Stopping unwanted heat from sneaking into your home is one of the smartest ways to lower your electric bill this summer. Insulation, careful sealing, and the right window coverings can keep your cool air inside and the summer heat where it belongs—outside. Here are practical steps to seal, insulate, and shade your living spaces for maximum comfort and savings.

Seal Windows and Doors to Prevent Cool Air Leaks

Small gaps around windows and doors waste energy. Each little crack or poorly sealed spot allows your precious cool air to escape and lets hot air in. Sealing these leaks can help your air conditioner work less, drop your power bills, and keep rooms more comfortable.

Some simple solutions for sealing air leaks:

• Add new weather stripping around old windows and exterior doors.
• Use caulk to seal smaller cracks around frames and trim.
• Install door sweeps on entry doors.
• Check for gaps you might not think about—around baseboards, outlets, and pipes.

Sealing up these leaks is proven to cut energy costs and improve comfort. According to the EPA’s ENERGY STAR program, the right sealing and insulation can save you up to 10% on heating and cooling bills. Want a step-by-step guide? Take a look at Seal and Insulate with ENERGY STAR.

Insulate Attics and Walls for Summer Comfort

Insulation acts like a thermal blanket for your home. Without it, summer heat moves through your roof and walls, warming your living space and causing your AC to run nonstop. The thicker and more complete the insulation, the better.

Best practices for summer insulation:

• Install or upgrade attic insulation to slow the transfer of heat from the roof.
• Insulate exterior walls and floors above crawl spaces or garages.
• Use spray foam or rigid boards for hard-to-reach areas.
• Add attic ventilation to prevent heat buildup and protect your roof.

Proper attic ventilation is critical, too. It lets hot air escape before it can seep into your rooms, reducing your cooling costs and even helping your roof last longer. Curious why this matters? Get more details from the ENERGY STAR guide to attic ventilation and learn how it helps create a cooler, more efficient home.

Install Window Coverings to Block Solar Heat

Window coverings do more than add style—they block heat and keep your spaces cooler. When strong sunlight pours through your windows, it can increase indoor temperatures by several degrees. The right window treatments can be a simple but effective solution.

Here’s how you can keep the heat out using window coverings:

• Reflective drapes bounce sunlight away before it warms up your room.
• Blackout shades can reduce heat gain while darkening your space—a bonus during heatwaves.
• Insulated curtains help trap cool air inside and stop hot air from sneaking in.

Choosing window coverings with a reflective or thermal backing blocks far more heat than thin blinds or bare glass. In the summer, closing these during the hottest part of the day can make your room feel noticeably cooler—and help your air conditioner take a much-needed breather.

A mix of sealing, insulation, and well-chosen shades holds onto your cool air just like a cooler holds ice. Each layer builds on the last, locking out heat and locking in savings.

Cool Smarter, Not Harder: Make the Most of Fans and Ventilation

Turning your home into a cool retreat isn’t about running the AC full blast all day. You can boost comfort and lower your electric bill by working with air—not just against the heat. Let’s break down how ceiling fans, smart ventilation, and managing heat sources inside your home will help you stay chill this summer.

Use Ceiling Fans to Extend Air Conditioner Efficiency

Ceiling fans are your power-up for summer comfort. When fans spin, they create a gentle breeze that helps sweat evaporate from your skin, making you feel up to four degrees cooler. This means you can raise your thermostat setting by a few degrees and still feel comfortable, so your AC runs less often.

• Set your fan blades to spin counterclockwise in the summer. This pushes cool air down and helps circulate it.
• Every degree you raise your thermostat can save around 3-5% on cooling costs. Fans help you do this without giving up comfort.
• Turn off fans when you leave a room. Fans cool people, not air, so there’s no point in letting them run when you’re not around.

Combining ceiling fans with your air conditioner isn’t just a luxury—it’s smart energy use that actually cuts your bill.

Enhance Natural Ventilation During Cooler Hours

Fresh air is free, and using it wisely can do wonders for your comfort. At night and early morning, open windows on opposite sides of your home to create natural cross-ventilation. This lets cool air flow in while pushing yesterday’s heat out.

• Strategically open windows after sunset or before dawn, when outside air is coolest.
• Shut everything tight—windows, blinds, and curtains—during the heat of the day to trap that cool air inside.
• Use window, box, or exhaust fans in the evening to help flush out lingering hot air and speed up the process.

Natural ventilation is a low-tech, high-impact way to give your AC a break and cut costs. For more detailed strategies on harnessing breezes and airflow in your home, take a look at this Natural Ventilation resource from the U.S. Department of Energy.

Avoid Heat Buildup from Appliances and Lighting

Some heat comes from outside, but a surprising amount is made right in your kitchen or laundry room. Ovens, stovetops, clothes dryers, and even old light bulbs add extra warmth you don’t want.

Here are a few tricks to stop appliances from making your home an oven:

• Run heat-producing appliances (like the dryer or oven) early in the morning or late at night when it’s cooler.
• Cook outside on the grill or try meals that don’t need the oven during peak heat.
• Switch to LED bulbs. LEDs put out way less heat and use less energy than old-fashioned incandescent bulbs.

Just a few smart swaps can make your whole home feel cooler—and they’re better for your budget. For a guide on improving both lighting and summer insulation, check out this How to Insulate Windows to Keep Heat Out guide, which also touches on minimizing indoor heat from different sources.

You don’t need to overhaul your home to take advantage of fans and fresh air. With these upgrades and simple shifts in habits, you can stay cool and cut costs at the same time.

Adopt Energy-Saving Habits with Everyday Appliances

Everyday behaviors can have a big impact on your summer electric bill. Beyond the big stuff like insulation and air conditioning, the way you use your water heater, washer, dryer, and even your electronics can chip away at costs day after day. Here’s how to create easy, money-saving routines with the appliances you use most.

Set Water Heater Temperature to 120°F

Turning down your water heater is a fast and painless way to lower your energy costs. Most units come set from the factory at 140°F, but 120°F is plenty for hot showers, dishes, and laundry. Dropping the temperature not only saves energy—it also reduces the risk of scalding and can make your water heater last longer.

Simple tips for your water heater:

• Check the thermostat dial and lower it if needed. Many models let you adjust this yourself.
• Insulate the tank and the first few feet of hot water pipes to keep heat in.
• Take quick showers instead of baths to cut down on hot water use.
• Fix any leaky faucets right away—constant drips mean your heater works harder.

Wash Laundry with Cold Water and Air-Dry Clothes

Laundry day is full of chances to use less energy and still get great results. Modern detergents work well in cold water, so you don’t need to rely on your water heater to tackle most loads. Air-drying saves even more, and your clothes last longer, too.

What works best:

• Wash with cold water for regular loads—only use hot water for greasy stains.
• Run full loads when you can, since washers use nearly the same energy for partial and full loads.
• Use the high-speed spin cycle to wring out more water before drying.
• Air-dry using a clothesline or drying rack whenever possible.

Washing in cold water can make each load cheaper, while skipping the dryer on sunny days can be a refreshing habit and kinder to your summer bill. This laundry energy-saving page covers even more tips you can use right away.

Unplug Electronics and Use Power Strips

Devices draw power even when turned off—a sneaky trick called “standby” or “phantom” load. If you have chargers, gaming systems, or appliances plugged in 24/7, you’re likely paying for electricity you don’t use. A few smart tactics can stop this silent waste.

How to curb standby power:

• Plug TVs, computers, and AV equipment into power strips, then switch them off completely when not in use.
• Unplug rarely-used chargers and kitchen gadgets after you’re done.
• Consider smart plugs or timed outlets for items you forget to turn off.
• Don’t forget about devices in bedrooms and guest rooms—they add up, too.

Participate in Utility Demand Response and Off-Peak Incentives

Utility demand response programs reward you for shifting your energy use away from high-demand times—usually the hottest hours when everyone is running their ACs. Here’s how they work: the utility alerts you to reduce power use during peak events, maybe by turning up your thermostat, running fewer appliances, or using less lighting for a few hours.

Typical incentives include:

• Bill credits for cutting power during peak hours.
• Cash rewards or rebates for joining and participating in demand response.
• Lower rates for shifting heavy energy use (like laundry or charging electric cars) to off-peak times, such as nights or weekends.

Many of these programs connect with your smart thermostat or home energy system, making participation seamless. Some utilities will even adjust your settings automatically—so you do less and save more. Want to understand more about how these programs work? The Department of Energy provides a clear breakdown of demand response programs and their benefits.
