Air Sealing

By using less energy for heating, cooling, and water heating, ENERGY STAR certified homes deliver approximately 20% savings on annual utility bills. Over the 7 to 8 years that a typical family lives in a home, you can save thousands of dollars in maintenance cost.

Properly Installed Insulation

It's not just the amount of insulation; it's the quality of installation that makes all the difference. Proper installation includes careful placement to eliminate gaps, voids, and compression; complete air barriers that prevent air from bypassing the insulation; and building techniques that minimize heat flow through framing. This ensures consistent temperatures throughout the house, reduced energy use, and increased comfort.

High–Performance Windows

Advanced technologies, like protective coatings and improved frames, help keep heat in during winter and out during summer. They also block damaging ultraviolet sunlight that can discolor carpets and furnishings.

Reagan Family

“We love the style, feel and location of our new home. When we learned it was an ENERGY STAR home, it was the icing on the cake. Saving money is what did it for us. We doubled the size of our home, but our energy bills were comparable. Plus, the temperature throughout the house is consistent so we're always comfortable.”
