Can out to a no cool. After performing a full diagnostic check on the system I found that the system had no TE flood protection nor Indoor Air Quality protection. I also found that the secondary drain pan had water in it. I checked the refrigerant levels and the system was low. I explained to the customer that there is an active leak and we would need to perform a leak check to determine the location of the leak. I also explained that it’s typically at the evaporator coil so I have options for a replacement of the evaporator coil. I also offered to have an Install Supervisor out to quote new equipment.
