Customer called and wanted to install a new drain pan because the current pan was rusting out and leaking water. I changed out the drain pan but also noticed that the coil was a block of ice. I saw that there was a kink in the suction line, I also noticed a bunch of air leakage from the supply side. I couldn’t check for a leak since the coil was frozen. Filters were clean. No sign of a restriction except the kink. I gave the customer estimates on basic systems. He will contact when he has made a decision. Collected $459
