Energy-saving Heating, Ventilation and Air Conditioning Tips

Air-Source Heat Pumps

Check your heating and cooling system for safety and efficiency. You can tell a heating and cooling system isn’t functioning properly if the temperature from room to room is varying, if the house feels too hot or too cold, and if the air is stuffy or clammy.


  • Choose digital thermostats on heating and cooling systems to control temperatures more accurately.
  • Keep your boiler running smoothly by having it serviced by a BPI-certified Home Performance with ENERGY STAR contractor.

Central Air Conditioners

  • Use a programmable thermostat when possible.
  • Choose digital thermostats on heating and cooling systems to control temperatures more accurately.
  • Make sure you're not covering your ducts with furniture, rugs, etc.
  • During the summer, keep all south-facing draperies closed during the day.
  • Change or clean your air filter based on the manufacturer's recommendation. This will make sure the unit is operating efficiently so you will realize your maximum energy savings.

Room Air Conditioners

  • Set your air-conditioning thermostat at 78 degrees Fahrenheit or higher during the summer season. Each degree above 75 degrees Fahrenheit saves you 3 percent of the energy used to cool your home.
  • Save money and increase your comfort by using a timer or programmable thermostat on your air conditioner.
  • Look for the ENERGY STAR label.
  • Place your air conditioner in a central window, rather than a corner window, to allow for better air movement.
  • Remove air conditioners in the fall or install a quality plastic cover.
  • Seal spaces around the air conditioner with caulking to prevent cool air from escaping.
  • Clean the cooling and condenser fans plus the coils to keep your air conditioner operating efficiently and check the filter every month and replace as needed.


When you go shopping for a dehumidifier, look for the ENERGY STAR label. Also look for the yellow EnergyGuide label to tell how energy efficient the product really is by comparing it with other dehumidifiers on the market.


  • Choose digital thermostats on your furnace.
  • Change your furnace filters every two months (or more often if you have pets) as they’ll help keep your furnace working efficiently for usually less than a dollar per filter.
  • Have your oil or gas fired furnace serviced regularly, typically once a year.
