Found system condensing fan motor locked up, capacitor weak, and contractor burned. Compressor was very hot and shut off on overload. Confirmed with manager it's okay to change the parts. Did so and ran and tested unit. Head pressure is very high and condensing coil is very dirty. Recovered one pound of refrigerant to bring heat pressure down. Head pressure is still very high but will drop with a good cleaning. Recommend a cleaning. Leaving an estimate to do so.
