Homeowner stated that the upstairs unit is not cooling,, that we were here couple of weeks ago for the maintenance. Found a bad capacitor (40/5) ,,,was replaced today , homeowner has parts and labor warranty. Unit was tested on cooling mode, unit draws 48 amp at start up,, highly recommended a hard start kit. We measured temperature differential, had 21 degrees split differential,, found no more issues/ concerns at this time.
