1. Install foam gaskets behind electric outlet and switch plate covers.

2. Aluminum tape wrapped around joints in heating and cooling ducts can help reduce costly air leakage.

3. Adjust or replace weather stripping, door sweeps, and thresholds as necessary. Make sure that they haven't warped, cracked, or broken and that they're still blocking the space between the window or door and the frame.

4. Enter and exit quickly. Every time an exterior door opens, a large amount of heat escapes, and cold air replaces it. Open outside doors as little as possible, and when you do, do so quickly.

5. Close chimney dampers. Warm air rises up and out open chimneys at an alarming rate. Close your damper as soon as you're certain the fire is completely out.

6. Air leaks are common at the joint between the chimney and the wall. To seal them, remove the trim (if necessary) and apply heat-resistant caulking.

7. Funding for air sealing work is available through the Energy Conservation Program.

1. Use higher density insulation, such as rigid foam boards, in cathedral ceilings and on exterior walls.

2. Ventilation plays a large role in providing moisture control. Attic vents can be installed along the entire ceiling cavity to help ensure proper airflow from the soffit to the attic, helping to make a home more comfortable and energy efficient.

3. Recessed light fixtures can be a major source of heat loss, but you need to be careful how close you place insulation next to a fixture unless it is marked "I.C." - designed for direct insulation contact. Check your local building codes for recommendations.
