My furnace is in great condition. I enjoy the comfort level with the continuous fan. However, expensive to run my current furnace with the continuous fan due to the cost. Draws 6.3 amps and costs approximately $950 a year.
Salesmen state that with a new furnace with an ECM motor only costs what a 100 watt light bulb would be for a year.
Is it possible to update my current furnace with a more efficient motor?
