If you don’t have a
programmable thermostat, buy one. The savings tally to nearly $200.00 a year. This way, when you
are out of the house, on vacation or sleeping, you can set your ‘stat
Search your house for leaky ducts. The majority of homes lose between 20%
to 30% of their cooling energy through leaky ducts.
Seal off any ducts to unconditioned areas, and insulate rooms like the
garage, attic or cellar. (Families with larger homes and empty nesters
consider not cooling the wing of the house no one ever goes into.)
It may be time for an AC upgrade. Get a qualified professional to inspect
your system. Look for models that have the EPA’s Energy Star and
replace filters at least every three months.

Regular maintenance will insure that your air conditioner operates efficiently throughout
the summer. Check the filter once a month by holding it up to a bright

Depending on the size of your home, you can save 3% on your cooling costs
for every degree you raise your thermostat in the summer. Raising the
thermostat from 73 to 78 degrees can mean savings of up to 15% in cooling costs.
To stay most comfortable during the hottest hours of the day, do your cooking,
laundry and bathing in the early morning or late evenings. These activities
all increase the level of humidity in your home, making it less comfortable
and forcing the air conditioner to work even harder. If other heat generating
appliances, such as irons, ovens and blow dryers are used only in the
early morning or late evening, your home will stay cooler.
Cook on the grill to keep cooking heat outside. When using the stove, vent
cooking heat outside with a range hood.
If you need to replace equipment, look for a high Seasonal Energy Efficiency
Ratio (SEER). The current minimum is 13 SEER for central air conditioners.
ENERGY STAR models are 14.5 SEER or more.
