Save energy and money. Find and plug the leaks in your house.


The heating and cooling of homes in the United States generates roughly 150 million tons of heat-trapping carbon dioxide each year, according to the U.S. Department of Energy. Big savings in energy and money can be achieved by making sure your house is well insulated.

The first step is to determine where the holes in your walls, attic and roof are. Hire an energy auditor to conduct a blower door test. A blower door is a powerful fan that mounts into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside and causing outside air to flow in through any unsealed cracks and openings. The auditor may use a smoke pencil to detect air leaks. 

Some municipalities offer free energy audits that include this test. If yours doesn't, information from the EPA can help you find a home performance Energy Star auditor in your area.

Once you’ve learned where the leaks are in your house, you can proceed to fix them. Some may be simple enough to do yourself; others may require professional help. Your auditor can help you decide.
