I want to replace the fan motor with a 2 speed one

i want to add a switch to the furnace so i can have the fan on all

will change to high speed.


I think many (most? all?) furnace/AC combinations already incorporate
dual speed fans. Are you sure it doesn't already have the capability
you seek? You might just need an appropriate thermostat.


I believe you are correct. The heat uses the low speed and the AC the
high
one.

Don www.donwiss.com (e-mail link at home page bottom).

guys its made in 1966 there was no 2 speed fans then

There also wasn't much central A/C. You sure the motor's that old?
