Tech confirmed unit is unlevel. Looks like some soil needs to be removed from under outer edge underneath package unit to allow a better drain angle. Tech quoted housecall and unit leveling out of the book. Customer was surprised by quote. Says she was told there would be no charge due to it being our install. Monica verified quote. Customer approved quote for leveling unit. Tech removed about 20 bricks from back exterior corner of package unit and rearranged so unit sits much closer to level. Tech observed better drainage flow after adjustments. There is a tree near unit and root system was pushing upwards on exterior rear corner of unit. Tech moved as many bricks as possible with only one tech and a shovel. Got before and after pics.
