Here is what the second site said:
"The main benefit of DC motor is the cost savings to the homeowner, DC Power cost's a fraction of what AC power costs to run so in the course of the lifetime of the furnace a customer can save thousands of dollars and has been proven that a high efficiency furnace with a DC motor pays itself off faster and in full with just the energy savings than a furnace with a multispeed AC motor.
"There were some studies done in the past and it was proved that A DC motor uses no more electricity than a single 100 watt light bulb! Which is incredible compared to the energy a normal motor uses.
"Other benefits of some furnaces with DC motor is the Variable action of the motor which adjusts itself to the demand that it needs rather than a fixed speed that is associated with a multi speed motor which only has one set speed at a time and needs a service technician to adjust it higher or lower.
"Finally the DC motors are quieter and are the only furnace that qualifies for significant Ontario energy rebates. Currently there is $1,030.00 in Government rebates available to homeowners to switch out your old furnace with a DC furnace. To see if you qualify visit our home page and click on the "Green Earth Friendly" Button on the Right side of the Screen. There you will see a breakdown of the rebates."
To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present.
