They are not rated at this time for furnaces, air handlers only.

What's the difference between a furnace-fan motor and an
air-handler-fan motor?

There is no difference in the motors. It's the control systems that
are different.


The retrofit isn't really practical from any standpoint, even
though it is possible to do.

Seems you're wrong. It's being marketed directly to HVAC repair shops
exactly as a replacement for furnace PSC motors.

I believe I said as much. This has nothing to do with the practicality
of buying one.


"Evergreen AH is the world's first high-efficiency ECM replacement
motor that is designed to replace factory PSC blower motors in
residential air handlers. That means you can now offer your
customers the comfort and efficiency of ECM in an easy-to-install
replacement motor.

Built from the same trusted, field-proven ECM technology that is
found in millions of OEM systems nationwide, Evergreen AH uses up
to 25% fewer watts in operating mode and up to 74% fewer Watts
than a PSC motor in constant fan."

Quoting a salespitch isn't the equivalent of enlightenment. You
didn't even know that the thing existed until a few minutes ago. In
fact you thought (very wrongly) that you could throw a standard ECM
motor into any old unit. You should spend some time googling reliable
resources and less time stating your own uneducated opinions.
