Uv light Preformed a maintenance on 2 Ruud units. Indoor unit: I checked amps on the blower motors, I checked the electrical wires and connections, I checked the drain pans and drain lines, I checked the float switches, I checked the coils, I checked the Uv lights, the one upstairs was out and in need of replacement, I got the permission and replaced it, I saw no issues with the air handlers. Outdoor units: I checked the amps on the compressors and fan motors, I checked the capacitors, I checked around the contactors and the boards, I looked into the units for rubbed wires and rust, I vacuumed the drain lines, I washed the units down with water, I saw a little bit of rubbed wires on the one of the outdoor units, I pulled the wires back and taped them up.
