Maintenanced the 2 rooftop units. Cleaned out both drain lines Checked filters Checked fan speeds on both units. Cleaned all supply and return grills Recommend replacing unit 2 as soon as possible. Found a few rust cracks in bottom of unit which is allowing water to drip down into building when it rains outside. Recommend also getting the curb sealed properly around the new unit once it’s replaced. Not sure if there is a “bandaid” service to prevent the water going into building other than replacing unit.
