Why Commercial Building Controls Require a Specialist

When any part of your commercial property’s HVAC (heating, ventilation, and air conditioning) system is not operating properly, it may be because of an error in the commercial control system. Commercial control systems are either electric, electronic, or pneumatic, but any type serves the same function: to control every component of the HVAC system associated with the air handler automatically. Commercial control systems are set up to monitor a number of processes and settings, such as the temperature of the supply and return air, the temperature indoors and outdoors, the humidity in the building, and the air pressure through the vents.

These control systems can help an expert to adjust the supply fan in the ducts, the valves of a hot- or chilled-water system, dampers, or electric heating strips. When one of these doesn’t seem to be working as needed, you may consider attempting to access the controls and make adjustments yourself. However, it’s important that you only allow a professional deal with these systems. This means making sure that your technician is a commercial specialist with experience installing and adjusting large commercial building controls.

There are several reasons that an expert is the best person for the job. For one, commercial building controls can be complicated to understand, and an exclusively residential technician is not familiar with many of the settings and setpoints managed in the control panel. In fact, there may be hundreds of different settings for any single control panel. It’s also best to have a technician who has some preliminary knowledge of the fault codes that may come up upon troubleshooting the system, and who has access to a fault code guidebook, although the malfunctioning part may require a lot of background knowledge to diagnose as well.

Trained technicians take care in replacing sensors, controllers, and safety switches, as they know that the replacement piece can suffer damage from improper handling. They also know the different precautions to take when working with electronic vs. pneumatic systems, for example, and what safety procedures to taking when working with electrical equipment.
