Then everyone asks why. Compressor rooms often run two or more compressors in parallel, each with its own pressure switch. Each switch reacts to the same pressure drop alone. One unit takes most of the run hours and wears out first. At peak demand, pressure sags while a spare unit stands idle.\u003c\/p\u003e\n\u003cp\u003eA failed unit goes unnoticed until the pressure falls. Service on one unit stops the air. Maintenance follows the calendar instead of run hours.
