You are right slow for heat and fast for A/C. Here are the blower speeds black is high blue is med. and red is low if you have orange it would be med low. Look on the control board and see what color wire is connected to heat and let me know if you have something other then control board. You can take the wire that is on park and swap them around. ken

SOURCE: blower fan wont shut off
Try cycling the switch at the furnace to reset the blower board. If this doesn't work remove the green wire from the blower board(computer board) to eliminate a shorted t-stat or shorted wire between the furance and t-stat. If blower remains on, then blower board is shorted. I've seen all these problems.

The central air units are designed to run at a specific speed (100%) if its older unit. The problem with putting in a slower speed motor(2speed) is the unit will still run at max speed. (nothing to regulate the speed). If you contact your local HVAC shop its possible they may be able to convert your unit (but I doubt it). They do have new units that run at 2 speeds when demand is low and run at a higher speed when the demand requires more cooling. Check this link out. Has a little more info. http://www.air-conditioners-and-heaters.com/two_speed_central_air_conditioning.htm

Its fine. That's your expansion valve you hear. the outdoor units fan runs to cool down your compressor. Don't worry about it.
