Upon arrival found system leaking water. On inspection found area of concern and made a minor repair. On further inspection found that the system was low on refrigerant. Added 2 pounds of 410a refrigerant. Also recommended on replacing the weak dual run capacitor. We moved forward with all repairs. Cleared drain line and drain pan. Cleaned up as much water as possible around the air handler. Recommended on placing a fan in the return to dry up some of the wood. Left system in good working order.
