These steps pay for themselves in a short time by reducing energy use.

Seal air leaks.
Caulk around the window and door frames (non-moving parts). Add weatherstripping and door sweeps to doors, or replace weatherstripping as it wears out. Use caulk or expanding spray foam to insulate where plumbing wiring and ducting penetrates through walls. Learn more in our Weatherization section.

Choose a programmable thermostat.
Newer models have “smart” features such as pre-programmed “night” and “vacation” settings that automatically adjust the temperature. But remember a thermostat is just a tool to help you save — you still need to choose energy-efficient settings. Learn more in our Thermostats section.

Schedule tune-ups for your heating and air conditioning system.
Regular maintenance will help your system run more efficiently. See our Heating & Cooling section.

Install window coverings.
Install insulated draperies or other energy-saving window coverings. Be sure to close them at night.

Install foundation vent covers.
Do this in the fall to keep wind and cold air from creeping in under your house (vent covers can also help prevent frozen pipes). Remove them in spring.

Before investing in air conditioning, consider a whole-house exhaust fan.
Open your windows in the early morning or at night and the fan will draw in cool air and expel hot air. Learn more in our Ventilation & Air Conditioning section.

Insert a fireplace pillow.
In addition to closing the damper, you can buy a plastic, inflatable “pillow” that inserts into the chimney to stop heat from escaping up the chimney when the fireplace is not in use. Contact your local fireplace dealer or search online.

Install high-efficiency showerheads and faucet aerators.
New showerheads are required to meet a 2.5 gallon per minute standard; the lower the number, the more you’ll save. For $10-$20, you can replace your showerhead and save water and energy. Low-flow showerheads can be hard to find locally, so it’s best to call. Try George Morlan Plumbing or shop online. If you have a pre-1992 showerhead, it could be using 5.5 gallons per minute or more. That adds up to 50+ gallons when you are in the shower for more than 10 minutes! Fix leaky faucets, too.

Use lighting controls.
Motion detectors, occupancy sensors, timers and dimmers can all help save on lighting. It’s also a good idea to put a timer switch on your bathroom fan; a fan can waste heated or cooled air if left running longer than necessary. About 10 minutes after your shower or cooking is done is usually sufficient.

Plant trees.
It will take several years before you see the benefit, but trees planted on the east, west and south sides of a house provide natural cooling through shade, reducing the need for air conditioning. Deciduous trees will shade in summer and allow more light in winter. Trees can also form windbreaks to protect your home from chilly winter winds.
