I was called out originally for the system not cooling. I came in to the system being off. I went into the attic and checked the blower, capacitor, wiring, and control board. I proceeded to the thermostat and checked the wiring. I turned the unit to cool and the system came on. I checked ,y temperature drop. It has a 19 degree temperature drop. I checked the compressor, condenser fan, contactor, capacitor, refrigerant, and rinsed the outdoor unit. The filters probably need to be replaced but the customer did not have them at the time of service. I could not determine the root of the issue. I cycled it a couple times to attempt to replicate the issue. I told the customer to reach out if something else happens.
