Our customer in Glendale, California, reported a strange fishy smell permeating their store. After checking in with the manager, our A/C technician inspected the system. Filters were only slightly dirty and didn't smell, evaporator coil wasn't clogged. Drain pans were clean. Tech noted several plumbing vent tubes near the unit, but the unit doesn't have any fresh air intakes. Unable to locate source of the smell as there was no fishy odor while onsite. Our tech sprayed down the evaporator with coil clean and disinfected the system as a preventative measure. Added some adhesive to re-attached fallen insulation on the door, and reprogrammed the thermostat. No more issues to report.
