Single Stage Furnace With Ecm Motor

I m sticking with single stage as all the contractors recommended them.

Single stage furnace with ecm motor.

With a 40k low stage the 2 stage will not be a reduction in comfort or gas efficiency over a single stage furnace. Instead either use a. Be sure to not use the built in staging timer if you go that route. Output of the motor can be adjusted by signals from a controller or permanently programmed to advance through a range of speeds during each on cycle of the furnace.

And the ecm motor will have greater electrical efficiency. 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. This increased precision results in a home that is more consistently heated both in different areas of the home and over time.

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.
