Upon my arrival in Elgin I did Air Conditioning. I spoke with the customers about their concerns with the system not cooling. Performing my diagnostics I found there wasn’t any high voltage present at the outdoor condenser due to a tripped breaker. I verified the compressor was not grounded and all ohm readings were within range. I also verified the voltage enhancement system was within range. After verification I turned the system on to check pressures and amp draws finding them to be within the manufacture specifications. I spoke with the customer about my findings and recommended having the breaker replaced for the system given it’s showing signs of weakness. They do have a handy man that can replace this for them and will have it done. System is currently cooling with no issues. They did not wish to sign back up for maintenance.
