Preformed a maintenance on a Lennox unit. Indoor unit: I checked amps on the blower motor, I checked the electrical wires and connections, I checked the drain pans and drain lines, I checked the float switch, I checked the Uv light, I checked the coils, I noticed a light amount of rust on the coils. Outdoor unit: I checked amps on the compressor and fan motor, I checked the capacitor and the hard start, I checked around the contactors and the board, I noticed some spider webs forming, I wiped them away, I also noticed some wear to the contactors, I looked into the unit for rubbed wires and rust, I vacuumed the drain line, I washed the unit down with water.
