Costumer stated that another individual already diagnosed a bad compressor and will be repairing it. No diagnostics performed.

Observed noise with compressor operating. Refrigerant pressures seem as expected. Voltage, compressor amperage, and capacitor test okay. Verified air flow and clean air filter. Temperature difference at condenser 53 supply 62 return. Customer has thermostat set at 58 degrees. Suspect noise is due to low outdoor temperature and very low indoor setting. Recommend follow up visit on higher temperature day to perform full system operation check.

Tech found the thermostat in the kitchen not cooling due to the thermostat being set to 90 on cooling, set temperature to 70 and system operated in cooling. System condenser is extremely clogged.
