With summer in full swing, you’ve probably noticed an uptick in your electricity bill. The hot temperatures and high humidity have been giving your air conditioner a real workout! Since your heating, ventilation, and cooling (HVAC) system uses the most electricity of any item in your home, taking steps to improve its efficiency will save energy and money. Try these five easy ways to stay cool for less:
Adjust the thermostat. Set the air conditioner thermostat to 78o F. For every degree setting below 78o F, you spend up to 4% more in cooling costs.
Use fans. Ceiling and floor fans move air to create a breeze, which can make a room feel up to four degrees cooler than the actual temperature. This allows you to set the thermostat higher and still be comfortable. Ceiling fan blades should move in a counterclockwise direction to create a downdraft – you can adjust the direction by moving the switch located on the side of the motor casing. Tip: Fans cool people, not rooms, so turn off the fan when you leave the room to save more money on your power bill.
Use window coverings to control sunlight. East- and west-facing windows catch the brunt of the sun’s heat, adding extra warmth to those sides of your home. Keep blinds and drapes closed to block out morning or afternoon sunlight so your air conditioner doesn’t have to work harder to cool those rooms.

Change the air filter. Dirty air filters restrict airflow and may cause the HVAC system to run longer, increasing your energy bill and potentially shortening the life of the unit. Many newer HVAC systems shut down if the filter becomes too clogged for air to pass through the filter; this prevents the compressor motor from overheating. When this occurs, a service technician must inspect and reset the unit, resulting in a service charge. During periods of high use or if you live in a dusty area or have pets, check and change your filter monthly, even if the filter is labeled to last three months. Pick a day that’s easy to remember, like the first of the month or when you receive your power bill in the mail. Make sure you use the filter type and size recommended by the manufacturer for optimal efficiency. While you’re at it, dust your ceiling fan blades, too!
Have your HVAC system serviced at least annually. Schedule a maintenance check on your unit at least once a year. A trained technician will check the coolant level, drain line, and overall system to make sure everything is operating at peak efficiency. If you live in a manufactured home, it’s especially important to check the ductwork to ensure it has not separated at the seams, resulting in a loss of cool air inside and higher electricity bills. Routine maintenance will head off potential problems, extending the life of your unit and promoting efficient operation for reduced power bills. Tip: Prune back shrubs that may block airflow to your air conditioner compressor.
