Try these low- or no-cost tips to boost your household’s energy efficiency:

Protect the Exterior

• Small cracks cause big heat losses. Caulk around the frames of all your windows and exterior doors.
• Replace or repair dried and cracked window putty. Also replace, patch or tape cracked or broken panes of glass to reduce air leakage and drafts.
• If you have single-pane windows, install storm windows on every window in your home and storm doors on all exterior doors.
• Locate your trees, shrubs and fences to provide maximum shade, wind and sun protection. Trained nursery personnel can help you design a landscape plan with energy efficiency in mind.
