Tips

Turn on your furnace fan so that it is constantly on during colder periods- it will circulate the warm air throughout the house.
Vacuum registers and vents regularly, and don't let furniture, draperies, area rugs or other objects block the airflow. Obstructed vents have to work harder to heat your home, and will increase your energy costs.
Use your ceiling fan in the winter to help circulate air throughout the house. Fans running counter clockwise, and set on low will push the warm air lower where you need it most.
Keep the area around the furnace and water heater clear so that the air supply to the appliance is not blocked off.
Use the black and yellow EnergyGuide labels on new furnaces, air conditioners and other major appliances to compare their energy use, efficiency and estimated annual operating costs.
The EnergyStar^® logo helps you identify high-efficiency appliances. This designation means the appliance exceeds minimum federal energy use standards, usually by a significant amount.
Turning down your thermostat too far, could result in more energy being used to reheat the house than you might have saved. The thermostat should not be turned down more than 6°C below your normal household setting in the winter.
When you have your heating system checked, have the cooling system inspected too. A poorly maintained air conditioner is less efficient, consumes excess hydro, and eventually won't be able to cool the house.
Don't alter your furnace in any way and always turn the furnace power switch off before removing the furnace panels to inspect it. Replace all panels securely and turn the furnace switch back on when you're finished.
Have an experienced, licensed service technician do a safety check on all your gas appliances annually to ensure they conform to the original manufacturer's specifications.
Check your furnace filter monthly for maximum air cleaning efficiency. Vacuum, wash or replace it if it's dirty. Dust and dirt can quickly clog vital parts, making your furnace work harder and eventually break down.
Set the water heater temperature at 120°F - about halfway between low and medium. This saves energy, prevents scalding, and keeps unhealthy bacteria from growing.
Have your cooling system serviced every summer. Your air conditioner's efficiency will decrease dramatically if it isn't cleaned and checked regularly.
An air conditioner with a larger capacity than necessary may cool a home more quickly, but will also use more energy by cycling more frequently. Since it runs for a shorter period of time, it also won't dehumidify the air effectively.
When purchasing home comfort equipment, choose a reputable, knowledgeable contractor. A good contractor should be able to help you calculate energy savings and the payback period, and offer a range of brands and prices. Don't forget about warranties, service contracts, delivery and installation.
