People have a few simple things they can do to reduce their energy bills and make their homes more comfortable, according to Carl Pedersen, North Dakota State University Extension Service energy educator.

Building materials can expand and contract with summer/winter temperature swings. This movement easily can break seals that are meant to keep the conditioned air inside a home. By allowing air leaks to go unsealed, homeowners are letting money escape from their homes.

“Running a fresh bead of caulk around window and door frames can be an inexpensive way to reduce air leaks,” Pedersen says. “Caulk only costs a few dollars and a tube will go a long way.”

If your windows are old and replacing them is not in your budget, window films might be a good option. A wide variety of heat-shrink window films that will reduce heat leaks and convection air currents around windows are available.

Convection currents are caused as warm air from a home comes in contact with the cold air next to a window. The air drops and is replaced by more warm air from the home. This cycle continues to repeat and is what causes the cold, drafty feeling next to a window even though no air may be leaking through the window. Window films create an air pocket between the window and the film, helping keep the cold outside air away from the warm air in a home.

“Insulated window treatments are another great way to save a few dollars on heating bills,” Pedersen says.

Installed properly, quilted or pleated window coverings will create air pockets that can reduce heat loss signifi-cantly.

The advantage of these window treatments is that they can be opened on the sunny side of the house to allow the sun to add free heat to the home. In the evening when the sun goes down, simply shutting the blinds retains the heat.
