Came out for water damage to ceiling possibly from HVAC equipment. Customer has 3 2016 Trane Heat Pumps, only 1 in attic above damaged area. Inspected system and could not get to drain right above problem area. Confirmed the drain does run over problem area however cant exactly confirm issue without cutting into ceiling. Pumped out drain from outside to see if there was any water due to it being winter and customer hasn't ran AC in a while. Removed a lot of condensate out of line. This let me know water constantly sits in there during heating season and line does not slope properly. Inspected entire system and everything operational just drain issue and outdoor unit has dirt and debris could use cleaning. For current equipment recommended changing filters, chemically washing outdoor unit as well as using emergency drain line as new main drain then capping off old one. Emergency line is very short and would not have this same issue. However main recommendation is to have Install Supervi
