Proof positive that preventive maintenance is essential to maintaining equipment. This unit does not receive regular service and as a result, an issue that would have been found during a scheduled maintenance visit and what would have been an easy fix was not found until the blower assembly blew apart. Luckily, we are in the shoulder season where temperatures are not extreme. Had this happened during peak season things would have been much worse and the employee who complained of a “banging noise” from the unit would have been even more upset if they didn’t have air conditioning for an extended period during the middle of summer.
A minor repair that left unchecked, turned into a major problem for this building. The unit was completely inoperable until repair parts could be ordered and installed.
