• Completed 1,100+ residential and light-commercial service calls across metro Phoenix, holding a 97% first-visit fix rate on cooling no-cool and heat-pump failures. • Diagnosed refrigerant leaks, capacitor and contactor faults, and airflow restrictions; recovered and charged systems to manufacturer specs under EPA 608 practices, cutting callback rate from 11% to 4% in 18 months. • Installed and commissioned 85+ split systems and package units (2–7.5 ton), including 16 SEER2 heat pumps, and documented startup readings so warranty claims dropped 22% year over year. • Mentored two apprentices on lockout/tagout, brazing, and combustion analysis, and kept the service van inventory accurate enough to reduce parts runs by about 6 hours per week.

• Assisted lead technicians on 700+ installs and changeouts across the East Valley, including ducted splits, mini-splits, and rooftop package units up to 10 tons. • Pulled vacuum to 500 microns, weighed in refrigerant, and recorded superheat and subcooling so startup callbacks on apprentice-assisted jobs stayed under 3%. • Fabricated and sealed sheet-metal transitions and flex duct, improving measured static pressure on 40 retrofit jobs and cutting average supply-air temperature drop by about 4°F. • Logged time, parts, and photos in the dispatch app, keeping job notes complete enough that the office billed 98% of apprentice tickets without a follow-up call.

• Supported a 12-person facilities crew across 18 office and retail sites, completing filter changes, belt replacements, and condensate-drain clearing on a 90-day PM schedule with a 96% on-time rate. • Shadowed HVAC techs on rooftop unit inspections, learning electrical safety, gauge use, and how to spot dirty coils before a no-cool call. • Replaced 400+ filters and logged equipment hours so three sites avoided peak-summer compressor failures that had cost about $4,800 the prior year. • Kept shop and truck areas stocked and labeled, cutting average time to find common parts from 12 minutes to under 4.
