3. Fix leaky or dripping water faucets.
4. Clean or replace air filter on the furnace once a month.

8. Install glass doors on fireplaces and keep the flue damper closed when the fireplace is not in use.
9. Plant windbreaks to shield your house from the winter wind.

11. When purchasing new windows or a furnace, look for the ENERGY STAR logo which indicates a high efficiency product.
12. Insulate water pipes to the first horizontal pipe runs off the water heater or provide heat traps on both cold and hot water lines. All hot water pipes located in unconditioned basements/crawl spaces should be insulated.

20. Get a home energy rating to evaluate home energy improvements.
