Dominion is committed to helping our customers meet their energy goals. Most homes have significant air leaks in outer walls, doors, windows and other openings. This allows hot air to seep in and cool air to escape—driving up your energy costs.
Sunny windows account for 40 percent of unwanted heat and can force your air conditioner to work two to three times harder. Closing the blinds during the day is one solution. Installing curtains that you can close during the heat of the day can also make a difference. Turning off lights and the TV as you leave the room or unplugging unnecessary appliances are simple solutions that can yield immediate energy savings. The following tips can also help you take control of your energy usage:
In the summer, set your thermostat to the highest comfortable temperature. Dominion and the U.S. Department of Energy recommend 78 degrees for maximum efficiency.
Use programmable thermostats to save money by automatically turning up your AC while you're away.
Turn off and unplug everything possible when on vacation.
Turn off ceiling fans when leaving the room. Ceiling fans don't cool spaces, but cool people by creating a wind chill effect.
Replace or clean forced air heating/cooling system filters monthly.
A dirty or clogged filter is one of the top reasons AC units stop working.
Using an outdoor grill during hot weather lowers cooling costs.
When closed and lowered on sunny days, highly reflective blinds can reduce heat gain by as much as 45%.
