- In normal circumstances, over 40% of your energy bill is a result of heating and cooling systems in the home.
- Heating and cooling systems emit over a half billion tons of carbon dioxide into the atmosphere each year, contributing to global warming. They also generate about 24% of the nation’s sulfur dioxide and 12% of nitrogen oxides – which cause acid rain. So efficiency is important not just to lower the energy bill but to reduce emissions.
- Have your heating and cooling systems inspected, cleaned, tuned, and maintained on an annual basis by a professional.
- Be sure that all vents and chimney are clean and free of any obstructions and are installed according to code requirements.
- Set your thermostat as low as is comfortable in the winter and as high as is comfortable in the summer.
- Clean or replace filters on furnaces once a month or as needed.
- During the heating season, allow as much sunlight as possible to enter the home.
- During the cooling season keep window coverings closed during the day to prevent solar gain.
- Keep unused or unheated rooms closed to the rest of the house.
- If you purchase new equipment – buy those that are labeled with the Energy Star.
- Look for Annual Fuel Utilization Efficiency (AFUE) ratings and the Seasonal Energy Efficiency Ratio (SEER) on equipment and compare energy usage before you buy.
- Be sure that your duct system is properly sealed. Duct leakage can account for over 30% of heating and cooling loss.
- If your ducts are located in an unconditioned space (crawlspace, attic, etc.) then be sure that they are properly insulated.
- Be sure that your heating and cooling equipment has been properly sized by a professional.
- Use a programmable thermostat. They can automatically adjust your thermostat settings which will save you as much as 10% a year on your heating and cooling bills.
- Utilize passive solar design techniques to heat and cool your home. These applications are environmentally friendly and cost-effective.
