Commercial HVAC problems can be complicated, disruptive and costly. Operations may grind to a halt when employees are uncomfortably warm. A complete failure can send them home. You need a certified and trained technician who understands how to troubleshoot and repair commercial heating and cooling equipment in the 5-50 ton range.
In general, commercial service technicians should have a deep understanding of concepts like the refrigeration cycle, 3-phase electrical systems and air side fundamentals. Commercial systems are frequently integrated directly into a company’s core processes, so it’s critical for the technician to have experience repairing air conditioners, package units, commercial controls, economizers and make-up air units.
