Have your air conditioning system tuned-up for the season so that you are running at peak efficiency. Operating at peak efficiency will save you money because the system doesn’t have to work as hard to do its job!
Keep the thermostat constant. Continuously adjusting the thermostat can be very inefficient. You can, however, raise the thermostat 2-3 degrees during the day while you’re away to save money. For every degree you raise the setting, you can expect to cut energy consumption by up to 3-5%.
Flip the fan switch on your thermostat into the “fan on” mode when cooling the house. This process will ensure that air is always being stirred to prevent hot and cold pockets from forming.
Set air vents on the second floor to receive approximately 75 percent of the conditioned air. This will help even out the temperatures from the first to the second floor of the home.
Replace older windows with more efficient low-E glass. These windows help to reduce the effect of the suns warming rays. Also, keep storm windows closed.
Install an attic fan to help ventilate some of the hot air out of the attic. Attics can reach temperatures of 140 – 150 degrees and this buildup of warm air can make the upstairs of a home warmer than it needs to be. This makes the air conditioner work harder to do its job!
Run a dehumidifier in the basement if the basement is humid. A damp basement can add moisture to the whole house. A dehumidifier in the basement will help to reduce the humidity levels in your home, making it more comfortable throughout the hot summer months.
Clear or cut back shrubs and bushes from the outdoor unit. The sides of the unit require at least 12-18 inches of clearance for proper performance. Keep fallen leaves, grass clippings, foliage and other dirt and debris away from your outdoor unit. And keep the air conditioning coils clean, following manufacturers’ instructions.
Don’t block vents or ducts inside the house to assure air flow in the home. Caulk and install weather stripping around windows and doors (especially the attic) to close air gaps.
Use shades, blinds or curtains to keep sunlight out of the house. Keep windows and doors closed when the air conditioner is on. Turn off lamps, TV and other appliances when not in use and turn air conditioners off if you are going to be gone more than four hours.
