Understanding and How to Change Blower Speed on a Furnace Air Handler.

This video is to show how you can figure out the blower speed setup in your HVAC system, and what you can do do adjust said speeds. Recently I did a blower speed adjustment on the 2nd floor air handler and thought to show how it can be done. This covers speed adjustment on a PSC motor. *NOTE* If you attempt this, be absolutely sure that you have no power going to your system, especially before changing wires. The video will also explain other safety measures, as well as some for a demonstration which I will show.
