The good news is there are several inexpensive ways to keep your home cooler

As temperatures climb across the Houston area, air conditioners are working overtime, and so are many homeowners’ electric bills. With August typically bringing some of the hottest weather of the year, home cooling costs can quickly add up. The good news is there are several inexpensive ways to keep your home cooler while reducing energy use.

Close blinds and curtains during the day

One of the easiest ways to keep your home cool is by blocking sunlight before it heats your living space. Closing blinds, curtains or shades on windows that receive direct afternoon sun can help reduce indoor temperatures and lessen the workload on your air conditioner. Blackout curtains or thermal shades can provide even greater protection from the heat.

Adjust your thermostat

Experts recommend setting your thermostat to around 76 to 78 degrees when you’re home. Lowering the temperature won’t cool your house faster; it simply causes your air conditioner to run longer, increasing energy use and utility costs.

Take advantage of cooler mornings and evenings

When outdoor temperatures are cooler, open windows to let fresh air circulate through your home. Using fans to create a cross breeze can help flush out warm air before temperatures begin rising. Once the outside temperature heats up, close windows and window coverings to keep cool air inside.

Use appliances after sunset

Appliances such as ovens, dishwashers and clothes dryers generate extra heat inside your home. Running them in the evening or early morning can help keep indoor temperatures down while reducing the strain on your cooling system.

Change your air filter

A dirty HVAC filter restricts airflow, forcing your air conditioner to work harder than necessary. Replacing or cleaning your air filter regularly can improve your system’s efficiency and may help lower cooling costs.

Use ceiling fans correctly

Ceiling fans don’t lower the room’s temperature, but they help people feel cooler by circulating air. During the summer, make sure your ceiling fan is spinning counterclockwise to create a cooling breeze. Turn fans off when you leave the room since they cool people, not the air.

Other money-saving cooling tips

• Seal gaps around doors and windows to keep cool air inside.
• Use LED light bulbs, which generate less heat than traditional bulbs.
• Cook outdoors or prepare meals that don’t require the oven during the hottest part of the day.
• Consider installing a programmable or smart thermostat to better manage cooling schedules.

With a few simple changes, homeowners can stay more comfortable during Houston’s summer heat while helping keep monthly energy bills under control.
