Dispelling Energy Saving Myths

Some energy-saving myths have been repeated so many times that people believe they’re true. We’re here to set the record straight.

Myth 1: Replacing windows is a good investment

New windows can increase security and comfort, but they’ll take 20 to 30 years to pay for themselves.

Replacing single-pane windows with double-pane low-e windows will save energy and money, according to the ENERGY STAR® program website, but In a house with 20 windows, it’ll take you almost 24 years to recoup the cost of the new windows.

Myth 2: Exterior caulking is the best way to seal leaks

Done correctly, exterior caulking keeps out water. But if you want to make your house more energy efficient, work inside, not outside.

Seal attic air leaks and spray expanding foam in basement leaks, such as around cables coming into the house.

Myth 3: Closing registers saves energy

Most heating duct systems have so many leaks that closing a register won’t force more warm air into other rooms — it will force more air out of the leaks. In addition, forced-air heating systems are designed to operate with all of the registers open.

The fixed-speed blower won’t perform as well with registers closed and can create a whistling in the ducts.

If in the winter you want to close off a portion of your house, like the upstairs, talk to a rep from your furnace company or a heating specialist to determine the best way to save energy with your furnace.
