Tech performed esa on one system. Tech found aux pan is rusted and recommended having pan replaced along with adding eztrap and overflow safety to primary pan to help prevent water from backfilling in the future. Tech also recommends adding drain insulation to prevent condensation in attic. Will need aux pan for 3 ton air handler and about 10ft of insulation. Customer approved estimate, need to get parts and return to make repairs. Tech found no other issues at today’s visit. System is back on and operating properly at this time.
