• 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 clearly with customers on findings/recommendations/solutions, 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.
• Document service activities in detail (work orders, reports, photos, as-builts, recommendations) and maintain accurate records for billing, warranty, and continuous improvement.
