Summer energy efficiency: myth vs. fact

When it comes to energy efficiency, common misconceptions can cost you big money. Here are a few facts to keep you comfortable and save money this summer.

Myth: When I’m not home, keeping my air conditioner at a lower temperature throughout the day means it doesn’t have to run harder to cool my home when I return.

Fact: To save energy, set your thermostat to a higher temperature during the day, and lower it when you return home.

Myth: Closing vents on my central air conditioning system will boost efficiency.

Fact: Closing vents can cause the compressor to cycle too frequently and the heat pump to overload. You’ll also use more energy.

Myth: Time of day doesn’t matter when it comes to running my appliances.

Fact: Time of day does matter when running electrical loads. For example, take advantage of the delay setting and run your dishwasher at night to avoid peak times of use and save energy.

Myth: Bigger is always better when it comes to cooling equipment.

Fact: Too often, cooling equipment isn’t sized properly and leads to higher electric bills. A unit that’s too large for your home will not cool evenly and might produce higher humidity indoors.
