Case Study: Orlando Utilities Commission Service and Maintenance Program


Hill York’s maintenance agreement with the Orlando Utilities Commission helps keep the facilities OUC cools at peak comfort and
efficiency year-round.


Project Name and Location:  Orlando Utilities Commission – Chilled Water Division | Orlando, FL 32801

Project Status: Ongoing

Project Scope: Established in 1923, the Orlando Utilities Commission (OUC) is the second largest municipal utility in Florida. OUC provides electric and water services to nearly 230,000 customers in Orlando, St. Cloud and parts of unincorporated Orange and Osceola counties. To support its innovative OUCooling initiative, a service enabling commercial property owners to outsource the production of chilled water for their air conditioning, OUC needed a partner that could manage maintenance for five major chiller plants. With over 500 chillers under contract and a long history of reducing facility costs through preventive maintenance agreements, Hill York was hired in 2013 to anchor a service and maintenance program ensuring the reliable delivery of more than 35,000 tons of chilled water to multiple businesses and locations.

Of particular relevance to the OUC was Hill York’s expertise in overseeing maintenance programs that fulfill fiscal budgets and minimize downtime caused by equipment breakdowns. OUCooling’s diverse commercial customers who depend on the economy and security of chilled water plant cooling include Lockheed Martin, the upscale Mall at Millenia, the community of Laureate Park at Lake Nona, and the Orange County Convention Center.

Hill York’s experience in maintaining peak air conditioning performance for large venues was especially vital to the serving of the convention center. The second largest convention facility in America with 7,000,000 square feet of total space, it is cooled by a 17.6 million-gallon chilled water storage tank – the largest in the world.

At the convention center and other contracted locations, Hill York’s strategically designed maintenance plans provided significant immediate and long-term benefits to the OUC’s chilled water customers, including:

  • Improved efficiency of cooling systems and lower operating costs
  • Early detection and prevention of costly repairs
  • Extended equipment life cycles
  • Uninterrupted comfort throughout covered facilities

The partnership between the Orlando Utilities Commission and Hill York is ensuring consistent comfort and savings to a growing base of participating property owners. A focus on preventative maintenance plays a pivotal role in making the outsourcing of chilled water production a service that delivers results.
