Came out to complete quoted repair of replacing bad PSC blower motor and outdoor chemical condenser cleaning. When replacing blower new one called for 10mfd capacitor instead of original 25mfd. Swapped out and ensured operational. Upon finishing repairs rechecked pressures and found system undercharged. Made customer aware looks like it could use a couple pounds to get up to manufacturer specs. Customer approved to add 1lb only then will call back in near future to top off fully to manufacturer specs. Got temp splits up at vents from 17 degrees to 19 degrees. System now cooling at this time however made customer aware could be cooling more efficiently once we charge it up properly. They are aware.
