Sr. Commercial HVAC Tech

JOB SUMMARY

The Sr. Commercial HVAC Tech is a high-level field role focused on the mechanical restoration and optimization of commercial/industrial climate systems. You will spend most of your time performing advanced "heavy-hit" repairs—such as compressor change-outs and circuit diagnostics—while serving as the CMMS lead to ensure work orders are tracked and executed efficiently across the maintenance team.

CORE JOB DUTIES

Advanced Technical Responsibilities

• Heavy Component Replacement: Expertly execute major repairs including semi-hermetic and scroll compressor replacements, reversing valves, and TXV (Thermal Expansion Valve) installations on systems ranging from 5 to 40+ tons.
• Complex Troubleshooting: Perform advanced diagnostics on multi-stage Rooftop Units (RTUs), split systems, and air-cooled chillers, identifying issues with refrigerant flow, oil pressure, or electrical sequencing.
• Circuit Recovery & Restoration: Perform full system evacuations, nitrogen pressure testing, and vacuum pull-downs to sub-500 microns after major component failures.
• Industrial Controls: Troubleshoot low-voltage control circuits, VFDs (Variable Frequency Drives), and economizer logic to ensure maximum energy efficiency.
• System Charging: Precisely calculate and adjust refrigerant charges (R-410A, R-22, etc.) for large-tonnage equipment with complex piping runs.

Supervisor & CMMS Responsibilities

• Work Order Dispatch: Monitor the CMMS dashboard to prioritize calls and assign routine PMs to the team based on geographical proximity and skill level.
• Asset History Tracking: Use the CMMS to document specific repair data (e.g., suction/discharge pressures, amp draws) to build a "digital birth certificate" for every 5–40-ton unit in the portfolio.
• Technical Mentorship: Act as the "on-call" resource for off hour and weekend emergency HVAC facility issues.
• Parts Accuracy: Ensure all parts used in major repairs are logged in the CMMS to maintain an accurate inventory and capture the true cost of maintenance for each machine.

REQUIRED EXPERIENCE, EDUCATION AND SKILLS

• Experience: 5+ years in commercial/industrial HVAC with a proven track record of "opening" systems for major internal repairs.
• Physical Proficiency: Expert brazing skills (oxygen/acetylene) and the ability to rig and hoist heavy motors or compressors safely.
• Software Comfort: Ability to quickly navigate a mobile CMMS app to update work orders while in the field.
• EPA Section 608 Universal Certification: (Mandatory) Full authorization to handle Type I, II, and III refrigerants without restriction.
• NATE (North American Technician Excellence) Certification: Preferred not necessary. Commercial Refrigeration or Service/Installation.
• OSHA 10 or 30 Construction Safety: preferred not necessary. Demonstrated knowledge of job site safety, lock-out/tag-out (LOTO) procedures, and ladder safety.
• Digital Proficiency: Proven ability to operate a mobile CMMS platform (e.g., UpKeep, Fiix, or Dude Solutions) for daily task management
