Human Error: A/C Unit Schedule and Set Point


$5,500 capital investment delayed by five years.

The Background

The unit was accidentally set to run from midnight until 7 am, the exact time that tenants were not in the building. This caused a host of problems in addition to tenant discomfort, including short cycling. Left undiscovered, short cycling increases wear and tear on the compressor and reduces the useful life of equipment. 

With interconnected problems, making a mistake in one place can have multiple negative effects. Without continuous commissioning, any one of these issues can lead to critical failure, costly repairs, equipment degradation, and tenant discomfort.
