for this job, I did a cooling tuneup on a Trane system. Drain lines were good. Blower motor cap in tolerance. On form I put X 13 but it is a PSC motor. Electrostatic filters were dirty, so I washed them for the homeowner. Delta was good. The condenser is DC Inverted so I didn’t run the normal electrical checks. Refrigerant levels were good. Washed out the coil and system was cooling and running when I left.
