Upon my arrival, customer was concerned that he found trace amounts of water on his air filter while changing it. During my diagnosis, I found the water removal system to be clogged from the outside with dirt and bacterial buildup. Informed customer of my findings and presented options for repair. Customer went with the HF3A option. I flushed the water removal system and treated it with bio protect. Tested systems performance and safety. System performing to manufacturer specifications at this time.
