Dispatched myself to a no cool single system home. Arrived to find system running but low on refrigerant. there is a visible oil and refrigerant leak inside the condenser coil. I Added 3 pounds of R 410 A to get system cooling properly. Larry showed me documentation of the condenser coil and system being under warranty, but no labor warranty . I am waving the cost of refrigerant and charging a diagnostic for tonight. Customer would like it to be done 3/1/2024
