Upon arrival the system was not running. After inspection I found the drain line to be clogged. There is a lot of zooglia buildup in the drain. Cleared and flushed drain line with vacuum and also nitrogen. Flushed with hot water 5-7 liters. Added a union before the p-trap for easy access in the future. Highly recommend iFlow to help mitigate zooglia buildup and help prevent clogged drains. Customer declined at this time. Offered membership renewal and customer will hold off. Estimates added. Unit is now cooling.
