Keep ductwork in good repair and wrap it with duct insulation.
Remove air conditioning units from windows.
Close your kitchen vent, fireplace damper and closet doors when not in use.
Warm Weather Conservation Tips
Keep the coils of your central or window air conditioner free of dust and dirt.
Make sure the output of your air conditioner is right for the size of your room or house to ensure optimum efficiency and comfort. Change or clean your air conditioning filter monthly during the cooling season to improve efficiency and the life of your air conditioner.
Look for an air conditioning unit that is ENERGY STAR® approved.
Cook on the grill to keep cooking heat outside the home.
Install reflective window coatings to reflect heat away from your home.
During the day, block the heat from the sun by closing windows, doors and curtains.
During the hot summer afternoons, avoid using appliances.
Open windows on cool summer days and nights. A good rule of thumb is not to open windows when the outside temperature is warmer than the inside of your house.
All Year Long Conservation Tips
Install a programmable thermostat. When used properly, it can shave $100 off your annual energy bills.
Use compact fluorescent lights. They last up to 10-13 times longer than standard bulbs and use 75 percent less energy.
Choose a high-efficiency water heater. An indirect oil-fired water heater produces an almost endless supply of hot water with a very fast recovery time.
Keep your oven door closed! Every time you open the oven door, the oven temperature can drop 25 degrees. Use the oven light or a timer to avoid wasting energy.
Wash clothes in the coolest water possible - 80 percent of the cost to run your washer is used for heating the water.
Install dimmers and motion sensors wherever possible.
Take showers instead of baths. A five-minute shower will use about 7.5 gallons of hot water; filling a bathtub can use up to 20 gallons.
Clean refrigerator coils once a year to extend the life of your fridge.
Choose a high-efficiency dishwasher - they use 25 percent less energy than conventional models.
Since your dryer retains heat, dry loads back-to-back.
