Employment History

HVAC Service Technician
Desert Peak Mechanical · Phoenix, AZ
Mar, 2021 · Present
Diagnose and repair commercial rooftop units and residential split systems across the Phoenix metro, averaging 6–8 completed work orders a day with strong first-visit resolution on no-cool calls. Recover, leak-check, and recharge refrigerant to EPA 608 standards, logging recovery weights and disposal on every sealed-system job. Run seasonal preventive maintenance on package units, heat pumps, and mini-splits, catching failing capacitors, contactors, and dirty coils before peak summer demand. Explain findings and repair options in plain language to property managers and homeowners, and keep service notes clear for the next technician on the route.
HVAC Installer Helper
Valley Comfort Systems · Tempe, AZ
Jun, 2018 · Feb, 2021
Set equipment, hung line sets, and assisted lead installers on residential changeouts and new-construction mini-split jobs throughout Tempe and the East Valley. Pulled condensate drains, mounted air handlers, and pressure-tested line sets so start-up crews could commission systems without callback leaks. Staged materials, labeled disconnects, and kept job sites clean on occupied homes, cutting return trips for missing parts. Learned brazing, vacuum, and startup checklists under senior techs and logged hours toward a full service role.
Maintenance Assistant
Sunridge Apartments · Mesa, AZ

Responded to resident work orders for filters, thermostats, clogged drains, and basic no-cool complaints across a 240-unit Mesa community. Changed filters, cleared condensate lines, and reset breakers on package units, escalating sealed-system and electrical faults to licensed contractors. Walked units with the property manager before peak heat, logging noisy condensers and dirty coils so vendors could schedule repairs before summer move-ins. Kept a simple parts closet and closed work orders the same day so the office could see what was finished.
