In a busy commercial facility, your HVAC system is often out of sight until it stops performing. For managers of hospitals, plants, or office complexes, a cooling failure is a direct threat to operational continuity and your bottom line. The primary culprit is often not a mechanical break, but a subtle imbalance in the system's refrigerant.

It’s 2:00 PM on a Tuesday in July. The outdoor temperature is climbing toward 95 degrees, and the humidity is thick enough to chew. Inside your facility—whether it’s a high-traffic retail space, a data center, or a manufacturing plant—the air has gone still. Then, the call comes in: the rooftop unit is blowing hot air, or worse, it’s completely dead.
