Dispatch said no charge for service call. Arrived to home and customer said unit would intermittently turn off. I found several items that I spoke to homeowner about such as the thermostat was not clipped into subplate which could cause issues. Also, the starting amps were exceeding manufacturer specs which is causing damage to compresser and raise power bills and lastly the primary cause is a bad Contactor. The voltage was there but it didn’t always make contact so compresser would not come on. Homeowner approved all repairs and got them signed up with a PMA and recommended calling in to get the maintenance scheduled here in the near future. Unit running at departure with a 21 degree TD
