Performed AC maintenance on a pair of Lennox condensers. Upstairs cooling split is 22 degrees. Indoor electrical component amperage is in range. Duct runs are sealed, condensate lines are clear. Downstairs unit cooling temperature split is 20 degrees. Condensate lines are clear. Duct runs are good. Outdoor units were chemically washed. Electrical components are in range at this time. Refrigerant levels are ok.
