Our company currently has a maintenance contract with North Kansas City Hospital and H&R Block World Headquarters, where we provide semi-annual tuning of the HVAC systems, UPS Battery IEEE testing, and generator load bank testing. What we have found is sensors can get clogged, adjusted and re-configured. By retuning and calibrating, many of these issues are corrected. In addition, mechanical systems break, and many times the facility operator will not know until the day the equipment is needed. Under our service contract we provide a list of control and mechanical components that need repairs. UPS batteries that are suspect are replaced, and generators are tested at full load and serviced.
