Providence United Methodist Church

Having a long-standing relationship with Providence United Methodist Church, United Mechanical Corporation was called in to tackle this delicate job. Because of their engineering background, United Mechanical knew that simultaneous cooling, dehumidifying, and reheating of the supply air would be the key to achieving the very specific temperature and humidity range requirements. Already in place was a 60-ton air handler, chiller, and boiler and United Mechanical wanted to save the Church money and make use of them. Other contractors, however, might well have suggested ordering all new equipment and substantially increased the overall cost of the project. An upgraded controls system turned out to be central to the proposed design. New controls were installed on the air handling unit to replace the old pneumatic ones, and control of the unit was added to their existing Building Automation System. The upgraded controls system was then programmed to maintain the required temperature and humidly range. Demand Control Ventilation was also added to manage the amount of outside air being treated. The United Mechanical in-house staff handled all the design work, engineering drawings, equipment procurement, controls programming, and installation—providing a single source solution for this critical project.
