No cool upstairs. System intermittently shut on and off. Upon arrival system was functioning. Customer stated they’ve had power outages but problem started before them. Issue did not duplicate itself today while onsite. Inspected all wiring connections and visually inspected control board and base of thermostat. All connections tight and no visible damage on any components. Found system to have minimal flood protection, dirty ac with a bush growing inside of it, weak dual capacitor and no IAQ. Quoted repairs. Customer signed up for Homecare.
