Tips on How to Save Energy and Money
Use Less A/C or None at All:
- Shades help keep heat out of the house: keep them closed during the day and open at night.
- A ventilated attic lowers the temperature in the house.
- Open windows allow for cross ventilation.
- Trees on the west side of the house can provide shade, cooling the structure.
- Fans use 90% less electricity than air conditioning.
Use Room A/C Efficiently:
- Cooling units are more efficient when located in a shady area of the house.
- Cool only the space that needs cooling.
- Keep doors and windows closed.
- Close all duct vents.
Use Central A/C Efficiently:
- Keep the shades drawn on the east and west sides of the house.
- Don’t run a dehumidifier while the A/C is on.
- Don’t run the dishwasher, clothes dryer or other heat producing appliances while the A/C is on.
- Keep the cooled space sealed off from un-cooled space.
- Run bath and kitchen fans sparingly.
Sign up for your utility’s A/C cycling program, which lowers bills with minimal impact on home cooling:
- Southern California Edison’s Residential Summer Discount Plan: A cycling device on your central air conditioner allows Edison to periodically turn off your AC remotely in return for a credit on your summer electric bills. The amount of the credit is determined by the amount of cycling you choose.
- PG&E’s SmartAC: A SmartAC device installed on your air conditioner by PG&E can be remotely activated in anticipation of a state or local energy supply emergency, cycling your AC off in 15 minute intervals. Customers earn rewards for participating.
- SDG&E’s Summer Saver: A device installed by SDG&E on your central air conditioner allows SDG&E to cycle your AC off remotely for a few hours on a limited number of summer days when demand for electricity is high. This helps maintain electric reliability and rewards participants with an annual credit on their SDG&E bills.
