Single Stage Furnace With Ecm Motor

And the ecm motor will have greater electrical efficiency.

Single stage furnace with ecm motor. I m sticking with single stage as all the contractors recommended them. Instead either use a. Variable speeds unlike an on off psc motor a furnace ecm motor can operate at a range of outputs between zero and 100 percent. So if those are your 2 options at the same price i d go with the 60k 2 stage.

A variable or multi speed furnace monitors the temperature of your home and then adjusts the speed of the blower motor sometimes referred to as an ecm motor in very small increments. Be sure to not use the built in staging timer if you go that route. With a 40k low stage the 2 stage will not be a reduction in comfort or gas efficiency over a single stage furnace. When a furnace or air handler with an ecm is installed on a good duct coil and filtration system with static pressures within proper design parameters it can perform flawlessly.
