Problem

Technicians inspected store equipment routinely or repaired it after visible problems appeared. Diagnosing faults could require opening equipment unnecessarily.

Approach

City US tested Discovery Sound Technology's machine-learning ultrasound system before announcing the partnership in August 2022. Its SOUNDTech+ tools recorded equipment readings and identified faults for technicians. By October, teams had performed hundreds of tests in customer stores.

Results

Over 70SOUNDTech+ tools deployed to field teams by October 2022, reported by CityCompany's own claim[1]

Takeaway

Technicians used the diagnoses to target repairs on refrigeration equipment. City reported field deployment and repair examples without quantifying overall maintenance savings.
