For this job I came out today to replace the customer's evaporator coil for the downstairs system. We sweat the old one out and brazed the new one in. Performed at decay test in the system held 150PSI for approximately 15 minutes and there was no signs of the leak. I pulled the vacuum on the system where it got below 500 microns and did not rise. I charged the system to a 26⁰ superheat as the system has a piston metering device. Customer would like to have an electrician come out July 15th after 2pm to look at some lights that are still blinking and flickering even after replacing the bulbs and a new ballast.
