Customer had us out for a second opinion for upstairs company. Another company said evaporator coil was leaking. Performed a leak search and found leaks at braze point at liquid line going into evaporator coil and suction line going into condenser. Pumped down system, fixed braze points, pressure tested and flushed system with nitrogen, pulled a vacuum to 500 microns and recharged system with 2 pounds r410a to a subcooling of 12 degrees per manufacturer specs. Signed customer up for three system maintenance plan. System is cooling at this time.
