Myths & Facts

Most Southern Maryland homeowners would rather spend their money on anything other than energy, and are willing to try a variety of methods to beat the heat for cheap; unfortunately, many of these methods may wind up costing you more in the long run. Here are five summer energy-savings myths debunked, to help get you back on the right track.

  1. Turn off the A/C while you’re out. A home that’s been left to heat up all day takes a lot of energy to cool back down, but leaving the A/C running in an empty home is wasteful. Instead, invest in a programmable thermostat and set it between seven and ten degrees higher than usual for times you are away or asleep, and back to your set point an hour before you’re due to arrive or awaken.

  2. Close the vents in unused rooms. There’s a good chance you have a balanced cooling system, designed to evenly distribute conditioned air throughout your home. Closing one or more vents in the hopes that this air will be diverted to another space won’t work, and will only result in chilly ducts.

  3. Leave a fan running to keep cool. Floor and ceiling fans can help maximize your summer energy savings, but are only effective in rooms that are occupied, as they only cool people, not spaces. This is due to the wind chill factor, where the continuous air movement quickens the evaporation rate of perspiration on the skin.

  4. Turn the thermostat way down to get cooler, faster. Unless your cooling system has a variable speed air handler, it likely operates at only one speed, meaning no matter how low you go, it’s still going to cool your home at the same rate.

  5. A/C is the only way to cool your home. Additional options include strategic placement of shade producing plants, keeping drapes or blinds closed on south- facing windows, or adding a layer of insulation in the attic to prevent heat transfer.
