Stay cool. Spend less. Stay safe.
Hot Texas summers are here — bringing extreme heat and higher electricity use. With the right tips and tools, you can beat the heat.

Energy-saving tips for every budget
- Set your water heater temperature no higher than 120 degrees, or 115 degrees if there are only one or two people in the household.
- Save on the suds. Wash clothes in cold water and try to do only full laundry loads; if you must do smaller loads, adjust the water level to match the load size.
- Get comfortable using fans, which can make you feel up to 6 degrees cooler. And don’t forget to turn the fans off in rooms you’re not using, as they just change the wind chill, not the actual temperature.
- Set your thermostat between 75 and 78 degrees when at home and above 80 degrees when away.
- Turn off kitchen, bath and other exhaust fans within 20 minutes after you're finished cooking or bathing.
- Use a garden hose to remove debris from the outdoor unit of your HVAC system.
- Open your refrigerator door as seldom as possible.
- Hang your clothes to dry when possible to save energy.
- Wait until you have a full load to run the dishwasher and let your dishes air dry.
- Move lamps, TVs and other appliances away from your thermostat.
- Replace your HVAC filters monthly. Dirty filters, coils, and fans reduce airflow through HVAC systems. Reduced airflow decreases system performance, causing the HVAC system to run more frequently.
- Add insulation around electric wall plugs and wall switches with foam pads. If you have an attic, make sure your attic door is insulated. While you’re up here, consider beefing up or replacing old attic insulation and you could save up to 15% on your electric bill.
- Block out the sun with blackout curtains or blinds. Windows let the sun’s rays warm up air in our homes, so these window coverings can reduce additional radiative heating.
- Have a professional inspect your HVAC unit, insulation and ductwork to spot potential problems.
- Install LED bulbs.
- Use a slow cooker or outdoor grill in summer months to keep your kitchen cooler.
- If you’re replacing old or damaged appliances, do your research and buy Energy Star approved appliances.
- When replacing an air conditioner, do your research and look for a high-efficiency model with a an Energy Star or EnergyGuide label.
- If you’re installing a new HVAC system, ensure your contractor uses a duct-sizing methodology, installs ductwork within the conditioned space (not in the attic) wherever possible; make sure that all ducts are sealed with duct mastic and are heavily insulated.
- Use smart thermostats for precise control and remote changes in temperature.
- Consider smart ceiling fans that auto-adjust.
- Install reflective window film or motorized blinds.
Making sense of your summer bill
How weather impacts your bill
- Air conditioning works overtime: As temperatures soar, AC systems run longer to keep your home cool.
- More sunlight means more activity: Longer daylight hours often mean more time spent at home using lights, electronics and appliances.
- Home efficiency matters: Older homes, aging appliances and poor insulation can all increase energy use without you realizing it.

Staying cool and safe
Your guide to energy use, summer safety and bill support.
The temperature comfortable for each induvial can vary. Aim for 78° F when you're home and active. Increase it to 85° F when away. Pair with ceiling fans for comfort — fans make you feel cooler without changing the actual air temperature.
Yes. Fans cool people, not spaces. A ceiling or portable fan can make a room feel up to 6°F cooler. Turn them off when you leave the room.
A Conservation Alert is a request from ERCOT asking Texans to voluntarily reduce their electricity use to avoid overloading the grid. This usually happens during extreme heat or unexpected outages at power plants.
• Bump up your thermostat two to three degrees • Delay laundry or dishwashing • Unplug non-essential electronics • Turn off unnecessary lights • Close blinds or curtains on sunny windows
