EnerGuide energy efficiency rating system

The EnerGuide energy efficiency rating system provides manufacturers and their dealers with the tools they need to promote the efficiency rating of their heating and cooling equipment.

energy efficiencyEnerGuide ratings for residential gas furnaces, central air-conditioners and air-to-air heat pumps are published on the back page of manufacturers’ product literature. The rating shows a horizontal bar scale that enables consumers to compare the equipment described in the brochure with the typical efficiency ratings of other equipment sold in Canada. EnerGuide ratings are based on standard testing procedures established by accredited certification organizations. Find out what the information on the EnerGuide Rating (AFUE/ SEER) means so that you can promote the sale of energy-efficient HVAC equipment.

HRAI administers and delivers the EnerGuide Rating System for HVAC Equipment in all provinces except Quebec.

How to save your energy and be more Energy Efficient?

  • Lower your hot water temperature by setting the thermostat to “low,” or below 120F.
  • Install a water heater insulation blanket if your heater doesn’t have an “Energy Guide” label indicating it as energy efficient.
  • Insulate the first 3 to 6 feet of cold and hot water pipes near your water heater. Insulating all hot water pipes is only necessary where pipes are located in a crawl space or attic. Keep foam insulation at least 6 inches from the flue of a gas water heater.
  • Turn your water heater control valve to “pilot” when you’re away from home for a week or more.
  • Set your thermostat to 78F in the summer. Note: The house will not cool down any faster if you crank up the thermostat past the desired temperature. Besides, it is easy to forget to turn it back down, which will waste energy dollars.
  • Turn the air conditioner off when away all day and during the night. Open the windows at night for natural cooling.
  • Regularly clean and replace filters to air conditioning units and appliances.
  • Seal, caulk and weather-strip the roof, walls, floors, around windows, doors, chimneys and cracks to keep the hot air out and cool air in. Insulate wherever possible, including attics, basement walls, crawl spaces, water heaters and ducts. Insulation can reduce your heating and cooling costs up to 30%.
  • Try to use appliances before noon and after 7PM.

Time-Of-Use Electricity Pricing energy efficiency

  • Set your hot water heater thermostat at 120 degrees or “low”. It’s hot enough for most needs and it cuts down on energy needed to keep water hot in the tank.
  • Wash when you have full loads. When drying clothes, use the proper setting and load size.
  • Install a whole house fan. A new whole house fan installed between ceiling joists in the house can help defer central air conditioning use, and cut down on electricity bills.
  • When replacing appliances or equipment, buy products with the Energy Star® label, the symbol for energy efficiency. Households that replace existing equipment with Energy Star® products can cut annual energy bills by up to 30 percent.
  • Activate your Energy Star® “sleep” feature on home office equipment so that it automatically powers down when not in use to save up to $70 annually in electricity bills and improve product longevity.
  • Replace incandescent bulbs with compact fluorescents that last ten times longer and require less energy.
  • During hot periods, close drapes and blinds to keep out direct sunlight.
  • Install glass doors in front of the fireplace to help keep warm air in the home.
  • Along with gas logs, add a cast-iron fireback to your fireplace to promote heat transfer into the room. Positioned against the back wall of a fireplace, a fireback protects the masonry of the back wall and radiates the heat of the fire forward.
