Pressure Controls
Pressure controls are HVAC parts that manage and maintain air pressure or refrigerant in air conditioners, refrigeration units, heat pumps, and chillers. They are integral for maintaining safe performance and improving energy efficiency. These controls monitor refrigerant pressure to make sure it stays within safe operating ranges by tracking the high and low-sides of pressure. They also protect the compressor by shutting it down preventing damage from overheating or freezing....Read more
System short cycling can be an indication that pressure controls are failing because they can prevent the compressor from turning on or cause it to shut down. If pressure controls fail to regulate refrigerant pressure, it can cause uneven temperature control. Another indicator that pressure controls are failing are gauges displaying incorrect pressure levels.
Regular maintenance can identify issues with pressure controls. Checking for cracks or wear on the terminals and housing and testing for proper voltage should be part of the maintenance process. Removing dust or oil buildup around the pressure controls and checking vent holes for blockages are also important steps in preventative maintenance.
