What is a high efficiency furnace and how do I know if my furnace qualifies?
High efficiency furnace is a term used to describe furnaces that are at least 90% efficient (two-stage, AFUE > 90%)*. That means that a minimum of 90% of the heat available in the gas is captured by your furnace for your home. These furnaces are often called condensing furnaces because they extract additional heat from the flue gas causing it to condense. Compared to standard furnaces, high efficiency two-stage furnaces may save up to 15% of the gas needed to heat your home.
Furnaces equipped with an Electronically Commutated Motor (ECM) have lower annual operating costs and can save you $40 to $300 per year depending on how you use the furnace fan. Some homeowners choose to run their fan continuously to help even out warm and cold spots in their home or to provide extra air filtration which maybe be valued due to health concerns.

What is an electronically commutated Motor (ECM)?
ECM is a brushless DC motor with all of its speed and torque controls built in. This allows the motor to adjust its speed to ensure the optimal airflow at all times. In addition ECM motors are significantly quieter and less expensive to operate than conventional furnace fans.
 ECMs use significantly less electricity to deliver the warm air from the furnace and the cool air from the CAC throughout your home. With their adjustable speed design, furnaces with an ECM motor operate with as little as 80 watts of electricity. That’s as much as ten times less than standard fan motors which run on high all the time.

What are the benefits of installing a High Efficiency Furnace with Electronically Commutated Fan Motor?
• Lower annual operating costs ($40-$300 per year) based on usage - that's 10 times less than a standard furnace fan
• As little as 80-watts of power required for operation - that's less than a standard electric light bulb
• Reduced temperature fluctuation
• Quieter running system
• Easier to maintain an even temperature throughout the home
• Lower drying effect of indoor air during the winter heating season
• Reduced stale air
