We have a hydro-air system with Trane blowers. They are each about the size of a refrigerator. Does anyone know how I can change the fan speed? There are 3 speeds that can be set, and the heating contractor said that it must be done from inside the unit. I opened the unit and did not see any switch. Is it a matter of moving wires? The air handler model #'s are TWE036C14 and TWE042C14. Thanks.

You must move blower motor wires. Shut off electric, open unit, follow wires from blower motor to connection points. Make your changes.
