Huge thanks, to Doug. With only a few pictures Doug was able to match a vintage motor that over 50yrs old. Had a new one in stock, and the staff even configured the wiring for a minimal fee.

Doug works the counter at Commercial Electric Motor. He really knows his stuff. If you talk to any HVAC tech around town, I can guarantee you that they know Doug or heard of him. Doug, or as I call him, Dougy knows everything there is to know about motors. If you are in need of a motor or some sort of rebuild or repairs, Doug is your guy, Commercial Electric Motors is the place.
