The furnace fan is 12 VDC and is a one speed fan. The air conditioner fan is 120VAC and is a two speed fan. There is, on most air conditioners, an audible difference that is noticeable when the fan switches speed.

Are you saying that your air conditioner only runs on one speed or that your furnace only runs on one speed?
