The customer called me to their home because their air conditioner was not cooling. I arrived and inspected the system and found that the float switch was filled with water. I turned the system on and off to see if it would run efficiently, but it was not. I informed the customer of the issue and they agreed to performing a drain treatment. I performed the drain flushing and vacuumed out the line with water and chemical. A lot of nasty gunk and slime came out. I primed the line with water and checked the pressures and temperatures. I also inspected all the capacitors and they were looking good. The customer paid $189 for the drain treatment with a card.
