Summer is just around the corner, the AC units are already buzzing.
But as outside temperatures rise, what’s the best temperature setting for the thermostat during the warmer months? And what are some ways to keep the ever-rising electricity bill down?
To save money, the U.S. Department of Energy recommends keeping indoor temperatures at a comfortable level that provides humidity control while minimizing the difference between indoor and outdoor temperatures.
You can save up to 10% per year on heating and cooling by adjusting your thermostat 7 to 10 degrees for eight hours a day – raising it in the summer and lowering it in the winter.
What temperature should you set your thermostat at in the summer?
Although the ideal temperature can vary depending on where a person lives, 78 degrees Fahrenheit is the recommended average, according to several energy companies, including Chicago’s Constellation, National Grid of New York and Massachusetts, and Carrier of Florida.
going away? keep the house warm
The Department of Energy recommends keeping the home warmer than usual while you’re away to avoid unnecessary air conditioning use. A programmable thermostat allows homeowners to begin cooling the home before they return.
Use fans wisely, no more than necessary
During the summer months, the fan blades should rotate counterclockwise. Rotating in this direction, the fan pushes air down to produce cool air, says HVAC manufacturer Trane’s website.
Ceiling fans should be switched off in rooms that are not in use. The DOE advises that fans cool people, not rooms, by creating a wind effect. And while showering or bathing, use a bathroom fan to remove heat and humidity.
Schedule routine maintenance
DOE also encourages homeowners to schedule routine maintenance to ensure cooling systems and appliances are working efficiently.
Before calling a professional, there are some maintenance tasks homeowners can do themselves:
- Use vacuum air intake vent regularly to remove dust accumulation.
- Keep the outdoor air conditioner unit clear of airflow obstructions for at least 2 feet.
- Make sure furniture is not blocking the airflow registers.
- Apply caulk and/or weatherstripping around doors and windows to seal air leaks.
- Consider lighting options that work in cooler temperatures, such as using LED lightbulbs.
- The DOE says avoid placing electronics near the air conditioning thermostat, as the thermostat senses heat from these devices and can cause the air conditioning to run longer than necessary.
Other Tips for Saving Money on Summer Cooling Bills
Here are some more tips on how to save money on AC bills this summer:
- Install window coverings to prevent heat from rising through windows during the day.
- Avoid setting the thermostat to a cooler setting than usual when first entering a space. This does not cool the space fast enough and can result in excessive, unnecessary expense.
- Wash lots of dishes and clothes for efficiency.
- If appropriate, open windows and turn off the air conditioning at night to let cool air in, then close windows and shades in the morning to trap cool air inside, advises Tran.
