Came out to a no cool on a 2021 r410a system. The customers stated that the system had shut down and not cooling. I checked the thermostat and it was on at the time. I went into the crawl space and found that the secondary pan was full of water and had triggered the wet switch. I checked the outside condenser and it was extremely low in refrigerant. The customer had mentioned that we had been out twice in the past six months once for the original install of his new furnace. I checked all of our braising points to assure there was no leak that may have occurred on our behalf. I identified the leak at the evaporator coil. I gave the customer options to replace the coil. Trane didn’t answer but I believe the coil is under warranty so there maybe additional discounts once that has been verified.
