Keeping your home cool during a Vallejo summer doesn’t have to drain your wallet. With rising energy prices across the Bay Area, homeowners in Fairfield, Solano, and beyond are seeking innovative ways to reduce their cooling costs without compromising comfort.

How to Keep Cool and Save Money This Summer

Here are our top tips to help you save money and energy this summer:

  • Adjust Your Thermostat

Set your thermostat as high as you’re comfortable with — ideally around 78°F when you’re home and even higher when you’re away. If you live in Napa or Martinez, where evenings can cool down significantly, consider turning the AC off at night and opening windows instead.

  • Seal Up Your Home

Gaps and leaks around doors, windows, and ducts let cool air escape and hot air in. Weatherstripping and caulking are affordable ways to improve efficiency. In older homes, sealing up can save you quite a bit on monthly bills.

  • Block Out the Sun

Keep blinds or curtains closed during the hottest parts of the day to reduce solar heat gain. In homes with large windows, investing in thermal curtains or window film can make a noticeable difference.

  • Use Fans Strategically

Ceiling fans help circulate cool air, making your home feel up to 4 degrees cooler. Just remember to turn them off when you leave the room — they cool people, not air. You can also set your fan to rotate counterclockwise in the summer, which pushes cool air down into the room more effectively. In homes without ceiling fans, portable fans placed near windows in the evening can help draw in cooler Bay Area night air while exhausting warm air out.

  • Keep Up With HVAC Maintenance

A dirty, neglected AC works harder and costs more to run. Changing your filters, cleaning around your outdoor unit, and scheduling a professional tune-up with A-1 Guaranteed Heating & Air, Inc. will help your system run more efficiently throughout the summer.

  • Consider an Upgrade

If your system is more than 10–15 years old, it may be time to upgrade to a high-efficiency unit. Many Bay Area homeowners are surprised to learn how much they can save — and don’t forget to ask us about available energy rebates in Vallejo and surrounding areas to help offset the cost.
