With summer just around the corner on the Central Coast, we’re all excited for longer, warmer days! Many homes here don’t have air-conditioning due to our mild microclimate and typically 70-degree weather. Instead, we rely on fans for those occasional hot days and warm nights. Whether or not your home has AC, here are some smart tips to keep your house cool, save energy, and cut down on costs this summer:
Block Out the Sun
Did you know that up to 30% of unwanted heat in your home comes from your windows through the greenhouse effect? Sunlight and heat enter, but they can’t escape. Installing energy-efficient window treatments, like reflective blinds, can help. When fully closed, these blinds can reduce heat gain by about 45%, keeping your home cooler during the hottest part of the day.
Open Windows at Night
Once the sun sets, open your windows to let the cooler evening air in. You’ll be surprised at how quickly the warm indoor air is replaced with cool, fresh breezes, making it easier to cool down your home naturally overnight.
Seal Air Leaks
To keep hot air out, inspect your doors and windows for any cracks or leaks. If you notice gaps or see daylight around the frames, use caulk or weather-stripping to seal them up. This small step can make a big difference in maintaining a comfortable indoor temperature.
Use Ceiling Fans Effectively
Set your ceiling fans to spin counter-clockwise in the summer. This helps circulate cool air and allows you to raise the thermostat by about 4 degrees without feeling less comfortable. If you’re using a window AC unit, place a fan nearby to help spread the cool air throughout the room and other parts of the house.
Create a Cooling Airflow
Harness the power of a natural breeze! Set up fans to create a cross-breeze by placing one facing inward on the side of your home that gets the wind and another facing outward on the opposite side. This technique will maximize airflow and cool your home more effectively, especially at night.
Maintain Your Appliances
If you have an air conditioner, make sure to regularly replace the filters. Doing so can reduce energy use by 5 to 15 percent. Also, check and clean the evaporator coils, as they can collect dirt over time, which reduces airflow and makes your AC work harder.
Avoid Heating Up Your Home
Using your oven can raise the temperature of not just your kitchen but your whole home. Try cooking with the microwave or stovetop instead, or take the opportunity to grill outdoors and keep the heat outside.
Do Household Chores at Night
Appliances like the washing machine, dryer, and dishwasher all generate heat. Running them during the cooler evening hours can help keep your home more comfortable during the day.
By following these simple tips, you’ll keep your home cool, conserve energy, and save money this summer. Enjoy the warmer months while staying comfortable and eco-friendly!
