The Silent Killer: How Poor MEP Sensor Placement Destroys HVAC Compressors & Your ROI
For over three decades, I've walked through thousands of mechanical rooms across the globe. From pharmaceutical cleanrooms to sprawling data centers, one critical flaw repeatedly emerges, silently draining budgets and prematurely aging equipment: HVAC Short-Cycling. It's not just an inconvenience; it's a multi-thousand-dollar systemic failure that often goes misdiagnosed. Many blame "faulty equipment" or "aging infrastructure," but the root cause is frequently far more fundamental: improper sensor placement and incorrectly configured control deadbands. The Mechanics of Self-Destruction: Why Short-Cycling Kills When a compressor starts and stops too frequently (short-cycling), it subjects the entire HVAC system to immense, unnecessary stress: Lubrication Breakdown: Compressors rely on a consistent run cycle to ensure lubricating oil returns from the system lines. Short-cycling prevents this, leading to oil starvation, increased friction, and eventual b...
