Came out because customer had another company come out for a maintenance and they told them that their compressor had a small leak and that the coil was leaking, but they couldn’t find where the leak was at after doing a sniffer throughout the whole machine did not find any leaks at the coil or at the compressor or any joints. Upon arrival. The machine was cooling properly and was not even on because I met temperature recommended customer monitor of the machine during the hottest times of the day and to call me back if it is not keeping up, the customer does not live at the home currently so he hast to go back back-and-forth to check it
