• Diagnose and repair residential and light-commercial air conditioning, heat pump, furnace, and rooftop unit faults, completing 6–8 service calls per day. • Perform refrigerant recovery, evacuation, leak checks, charging, and EPA-compliant documentation on R-410A and newer systems. • Install and commission split AC and heat pump systems, verifying airflow, static pressure, electrical readings, and manufacturer specifications. • Use electrical schematics, meters, and diagnostic tools to isolate controls, motors, capacitors, compressors, and sensor failures. • Explain repair options, maintenance needs, and warranties in clear customer language, maintaining a 95%+ customer satisfaction rating. • Record parts, labor, photos, and recommendations in ServiceTitan while following lockout/tagout and jobsite safety procedures.

• Assisted lead technicians with residential split-system, packaged-unit, and light-commercial HVAC installations from equipment set through startup. • Installed and sealed supply and return ductwork, flex connections, registers, insulation, line sets, condensate drains, and equipment platforms. • Supported Manual J load-calculation inputs, equipment sizing, material takeoffs, and scope reviews to reduce installation rework. • Performed brazing and nitrogen purging, pressure testing, evacuation, airflow checks, and basic electrical verification under supervision. • Maintained clean, safe jobsites in occupied homes and commercial spaces while meeting daily production targets and code requirements. • Prepared installation notes, photos, and punch-list updates for project managers and customers.

• Completed preventive maintenance rounds across classrooms, labs, offices, and mechanical spaces, escalating issues before they affected operations. • Changed filters, inspected belts, lubricated motors, and assisted with basic air-handler and packaged-unit checks. • Logged work orders, parts used, meter readings, and completion notes in the facilities tracking system. • Supported minor electrical, plumbing, lighting, and building-repair tasks while following PPE and lockout/tagout procedures. • Responded to staff requests professionally and kept tools, ladders, and work areas organized and safe.

Coursework included refrigeration fundamentals, electrical systems, load calculations, duct design, brazing, controls, heat pumps, rooftop units, OSHA safety, and EPA Section 608 preparation.

Universal certification covering Core, Type I, Type II, and Type III refrigerant handling; current knowledge of recovery, evacuation, leak prevention, and environmental compliance.
