Heating Unit As much as half of your household energy use goes to heating and cooling. Replacing older equipment with more efficient equipment will help reduce your carbon footprint and your energy costs.
Tune up your heating system in the fall to make sure that it will operate at maximum efficiency during the cold winter.
Air Conditioning Unit Check and clean or replace air filters every month. Clean the outside condenser coil once a year.
Schedule periodic maintenance of cooling equipment by a licensed service representative. A "tune up" in the spring will help the air conditioner run at maximum efficiency during the hot weather.
Water Heater Decrease your carbon footprint and reduce your water heating bill by 10 percent by lowering the water heater temperature from 140°F to 120F°. (Keep the temperature at 140°F if you use an older dishwasher without a temperature booster.)
Once a year, drain a bucket of water from the bottom of the water heater tank. This gets rid of sediment, which can waste energy by "blocking" the water in the tank from the heating element.
Locate water heaters as close to the points of hot water usage as possible. The longer the supply pipe, the more heat that is lost.
Insulate your hot water supply pipes to reduce heat loss. (Hardware stores sell pipe insulation kits.)
For older water heaters, consider buying a water heater insulation kit, which reduces the amount of heat lost through the walls of the tank.
