Performed 1 system diagnostic for upstairs unit. Found dirty filter, system had no charge and was out on low pressure, leak in the lineset at the sight glass and filter drier, no flood protection. Offer customer homecare but Custimer declined at this time. Went with bandaid option and leak search. Found leak fairly quick so gave additional discount of 150.. repaired lineset, replace filter drier, vacuum unit to below 500 microns, and charge unit to manufacture specifications. Unit is now cooling. The bare minimum basic repairs to get the system running today.
