NO COOL/GOOGLE. Found system operational upon arrival. Customer stated unit was running with warm air and the previous owners told him it might need to be recharged occasionally. Upon inspection found unit running fine. After about 5 mins unit shut off. Found condensation line backed up. Customer stated he could clear it and redo some of the pvc pipe. Customer agreed to add maintenance agreement for 1 year. Unit operational departure. Customer will take care of issue since he was a mechanic for many years and is mechanically inclined.
