Using less energy at home can start with making sure the air your heating and cooling system creates stays inside your home. This helps the system work more efficiently, making your home more comfortable and help lower your energy bills.

1. Seal the small gaps you can’t see 

Tiny cracks and openings around your home add up. Over time, they can be like leaving a window open all year. Focus on sealing gaps around windows, doors and anywhere air might sneak in or out.

2. Fix leaky air ducts 

If your ductwork has gaps or leaks, you’re losing heated or cooled air before it reaches your living space. Sealing ducts helps your system work more efficiently.

3. Add or upgrade insulation in key areas

Attics, walls and crawl spaces are common sources of heat loss, especially in older homes. Improving insulation in these areas can make a noticeable difference in comfort and energy bills.

4. Consider upgrading windows

Older windows can be a major source of drafts. Replacing them can help keep indoor temperatures more consistent.

5. Start with a home energy assessment 

A home energy assessment can help you understand where your home is losing energy and what to do next. Energy Trust’s free, online home energy assessment, provides personalized recommendations by answering a few quick questions.
