Service call for an emergency drain pan full of water. Technician found the upstairs system low on refrigerant causing the coil to freeze. A brief leak search was performed and no leaks were found here today. The history shows the system has been low for quite some time so 3 lbs of refrigerant was added here today. The system is running much more efficiently and right where the manufacturer wants it. The wire on the capacitor is still burnt up and in need of repair and two safety switches were installed on the emergency drain pans to prevent any water damage in the future.
