I need some help with my home HVAC system....HELP!!!?

What you need is a Rescue motor. That is the actually name. You want a fan motor not a blower motor. The Rescue motor is revesible and you need a five mfd capacator. You will need to use the new capacitor instead of the one it is currently connected to. That is all you need to know. Johnstone supply sells them and I believe Graingers does as well. Hope I have helped you.
