  1. Heating and Cooling Systems

  2. Saving Energy and Staying Safe • Efficient homes are tightly air-sealed and properly insulated. • If heating and cooling systems are working properly then you: • reduce pollution. • minimize health risks.

  3. Venting Combustion Appliances • National Fire Protection Association (NFPA) codes must be followed to ensure safe operation of combustion equipment. • It is critical that combustion appliances have enough air to run safely. • Sealed-combustion appliances draw air directly from outside the home. • Natural-draft and power-vented units draw air from the indoor space where they are located.

  4. Energy Consumption • The amount of energy you consume in your home depends upon: • How well the house is insulated. • The efficiency of appliances and equipment. • The local weather and climate. • Your lifestyle. • A home energy audit can identify how energy efficient your home is.

  5. Energy Efficiency • New heating and cooling units are more efficient than those 15 to 25 years old. • Equipment should be inspected and serviced every year and maintained monthly. • Air filters need to be changed or cleaned regularly.

  6. Adjusting Your Thermostat • Save energy by: • Setting the thermostat lower in winter. • Setting the thermostat higher in summer. • Using a digital thermostat. • Try a home energy manager which allows many temperature settings each week.

  7. Distributing Air Efficiently • If you have central heating and cooling, you have a system to distribute the air. • Make sure your ductwork does not leak so it won’t waste energy. • Insulate ducts in unheated space. • Properly seal any duct joints.

  8. Windows, Doors and Leaks • Air leaks can contribute to a home’s total heat loss. • Find leak points and seal them. • Doors and windows allow air to enter. • Cracks around door and window frames can be a primary source of heat loss. • Seal leaks with caulking and weather stripping.

  9. Insulation • Insulation prevents transfer of heat or cold air through walls, floors, or ceilings. • R-values measure how well materials resist the flow of energy into or out of your home. • The larger the R-value, the more heat or cool air stays in your home. • Find out the recommended R-value for your area.

  10. Hot Water • Lower the temperature of your water heater to: • save energy. • increase the life of your water heater. • reduce the chance of being burned by hot water. • Wrap your hot water heater with an insulated blanket. • Reduce your use of hot water.
