• Perform advanced repairs such as major component replacements (compressors, evaporators, condensers, controls, valves, pumps), refrigerant recovery/recharge/handling, system balancing, startup/commissioning, and retrofits/upgrades.
• Conduct thorough preventive maintenance, performance testing, energy‑efficiency assessments, leak detection, and system optimization to minimize downtime and extend equipment life.
• Lead full service calls from dispatch to completion: assess on‑site issues, communicate findings/recommendations/solutions to customers, coordinate parts and materials, execute work, and follow up for satisfaction.
• Ensure all work complies with codes, regulations, manufacturer specifications, EPA requirements, and Modigent safety/quality standards.
