Upon arrival, customer informed me that she had water leaking from her ceiling on the second floor and water spots on the wall on both the second and first floors. Customer stated that she thinks there was a pipe that burst in the wall. Customer stated that she saw water coming out of a pipe draining down to an awning outside of her window. I advised customer I would run a leak diagnostic. After doing a thorough diagnostic, I determine that the cause of the water was the air conditioning unit in the attic on the second floor. The condensate line is leaking from somewhere or the pan is overflowing, which is causing water to spread. I checked pressure throughout the house to make sure that customer had a good flow rate. Advised owner via telephone that we would just be charging him a diagnostic fee, a small one and the emergency dispatch fee. Customer satisfied.
