When summer hits full swing, the sun isn’t just heating up the outdoors—it’s heating up your home and your energy bills too. But don’t sweat it! With a few smart strategies, you can keep your home cooler, cut back on your energy use, and stay comfortable without overworking your air conditioner.
Here are some homeowner-approved tips to help you save energy during those hot summer days—and one bonus tip if you’ve got an attached garage.
1. Seal the Gaps and Insulate Smart
Before you crank the A/C, make sure your cool air isn’t escaping.
- Seal air leaks around windows, doors, and attic hatches with weatherstripping or caulk.
- Check attic insulation—this is a big one for keeping the heat out.
- Keep blinds or curtains closed during the day to block direct sunlight, especially on south- and west-facing windows.
2. Use Fans to Your Advantage
Fans don’t lower the temperature—but they make you feel cooler.
- Set ceiling fans to spin counterclockwise in summer.
- Turn fans off when you leave the room (they cool people, not rooms).
- Use portable fans in stuffy areas to keep air moving.
3. Adjust Your Thermostat Wisely
Every degree counts.
- Aim for 78°F (25–26°C) when you’re home and a bit warmer when you’re out.
- Install a smart or programmable thermostat to automatically adjust temps based on your schedule.
4. Keep Your HVAC System in Top Shape
A neglected system works harder—and costs more to run.
- Change air filters every 1–3 months.
- Schedule a professional HVAC checkup at the start of summer.
- Keep outdoor units clear of grass, weeds, and debris.
5. Choose Energy-Efficient Upgrades
If it’s time for replacements, choose energy-saving options.
- Upgrade to ENERGY STAR appliances when possible.
- Consider double-pane or Low-E windows to reduce heat gain.
- Use LED light bulbs, which give off less heat and use less power.
6. Re-Think Cooking Indoors
Summer is a great excuse to avoid the oven.
- Use microwaves, slow cookers, or outdoor grills.
- If you need the stove, try cooking early in the morning or later in the evening when it’s cooler.
7. Install Solar Screens or Window Film
Solar screens and reflective window film can help block up to 70% of the sun’s heat without losing all that natural light.
8. Plant for Shade
Landscaping isn’t just for curb appeal—it helps with cooling too.
- Plant trees or tall shrubs on the sunny side of your home.
- Use climbing vines or trellises for extra shading near windows and patios.
🌡️ Bonus Tip for Homes with Attached Garages
If your garage is attached to your home, parking your car outside after driving can actually help keep your home cooler.
Why? A hot engine radiates heat long after it’s turned off. When you park in an attached garage, that heat lingers—and it can seep through shared walls and floors into your living space, making your A/C work even harder.
Quick tips:
- Park outside until the engine cools down, especially after longer drives.
- Keep your garage well-ventilated if you must park inside.
- Insulate the garage wall shared with your house if it isn’t already.
Final Thoughts:
Staying cool in the summer doesn’t mean you have to sacrifice comfort or spend a fortune on your energy bill. Small changes—like sealing gaps, adjusting habits, and using your appliances more strategically—can make a big difference.
