HVAC Technician resume bullet points
Strong HVAC Technician bullets show a hiring manager that you can diagnose by measurement rather than guesswork, work safely and legally with refrigerants and combustion equipment, and leave jobs that stay fixed. The best ones tie each task to a concrete result such as fewer callbacks, passed inspections, restored comfort or saved energy, and show how your responsibility has grown over time.
Replace anything in [brackets] with your own numbers and details. Only use a bullet for work you have really done.
Installation and Commissioning
- Set [number] split-system condensers and air handlers per month, pulling each lineset down to [X] microns with a micron gauge before release, which eliminated refrigerant-side callbacks on new installs.
- Brazed copper linesets under a nitrogen purge and pressure-tested them to manufacturer specification on [number] installations, passing municipal inspection on the first visit for [X]% of jobs.
- Fabricated, hung and sealed [number] feet of sheet metal trunk and flex duct in [number] new-construction homes, reducing measured duct leakage to [X] CFM25 or less.
- Sized replacement equipment from Manual J load calculations on [number] retrofit homes, resolving [number] long-standing hot-room and short-cycling complaints.
- Commissioned [number] ductless mini-split systems and recorded superheat, subcooling and airflow readings in a startup report, giving customers documented proof of correct setup.
- Coordinated crane picks, roof curb adapters and electrical disconnects for [number] rooftop unit changeouts, finishing each within a single [number]-hour shutdown window so tenants lost no business hours.
Diagnostics and Repair
- Traced intermittent no-cool calls to failed run capacitors, contactors and ECM motors using a multimeter and clamp meter, restoring cooling for [number] customers during peak summer heat.
- Located refrigerant leaks with an electronic detector, UV dye and nitrogen pressure tests on [number] systems, preventing repeat recharges and saving customers about $[amount] in refrigerant costs.
- Diagnosed failed igniters, flame sensors, pressure switches and control boards on gas furnaces, restoring heat to [number] households during cold snaps with an average arrival-to-repair time of [X] hours.
- Ran combustion analyzer tests on [number] furnaces and boilers, identifying [number] cracked heat exchangers and elevated CO readings and removing those units from service before they became a safety hazard.
- Isolated reversing valve, defrost board and sensor faults on [number] heat pumps, correcting winter heating complaints without full system replacement.
- Found the root causes of frozen evaporator coils by measuring static pressure, airflow and charge, so that only [X]% of those units generated a repeat call within 90 days.
- Covered an on-call rotation of [number] after-hours emergency calls per month, stabilizing failed systems at medical, food-service and residential sites until permanent repairs were scheduled.
Preventive Maintenance and Commercial Systems
- Maintained [number] rooftop units across [number] commercial sites, servicing belts, bearings, economizer dampers and condensate drains and keeping unplanned shutdowns to [number] per year.
- Tuned up [number] hydronic and steam boilers each season by cleaning burners, testing safeties and low-water cutoffs, and adjusting air-fuel ratio, improving combustion efficiency by [X] percentage points.
- Cleaned condenser and evaporator coils and flushed condensate lines on [number] units before cooling season, cutting water-damage and drain-clog calls by [X]%.
- Logged amp draw, pressures and temperature split in the maintenance management system for [number] chillers and compressors, flagging [number] developing failures early and avoiding an estimated $[amount] in emergency replacement costs.
- Built equipment-specific PM checklists for [number] unit types, reducing missed tasks and giving property managers consistent service reports at every visit.
- Started up and shut down [number] customer systems for seasonal changeover, catching [number] worn parts before they failed under load.
Refrigerant Handling, Safety and Compliance
- Recovered, recycled and documented refrigerant under EPA Section 608 certification on [number] systems, maintaining leak-repair and charge logs that passed [number] customer or agency audits with no violations.
- Completed training on A2L refrigerants such as R-454B and R-32, then helped equip [number] service vehicles with compatible recovery equipment and leak detectors so the team could service newer equipment on day one.
- Enforced lockout/tagout, ladder and rooftop fall-protection procedures for a crew of [number], completing [number] months without a lost-time injury.
- Pulled permits and scheduled inspections with local code officials for [number] installations, preventing project delays and failed-inspection return trips.
- Verified gas line pressure and checked for leaks with a manometer and leak-detection solution on [number] furnace and boiler installs, documenting results for every inspection file.
- Led weekly tailgate safety talks on topics such as refrigerant burns, electrical hazards and confined attic work, contributing to [X]% fewer reported incidents year over year.
- Earned [certification, e.g. NATE or OSHA 10] while working full time, applying the new knowledge to [specific task] and shortening [process] by [X]%.
Controls, Airflow and Energy Efficiency
- Programmed and wired [number] smart and communicating thermostats, then walked customers through scheduling features that lowered their reported cooling or heating run time by [X]%.
- Adjusted setpoints, schedules and economizer sequences in the building automation system for [number] buildings, reducing HVAC runtime by [X]% without increasing occupant comfort complaints.
- Balanced airflow with a flow hood and manometer across [number] zones, resolving [number] hot-and-cold-spot complaints without adding equipment.
- Replaced standard blower motors with ECM motors and added variable frequency drives to [number] air handlers and pumps, cutting measured energy use on those units by [X]%.
- Installed and calibrated zoning dampers and static pressure controls on [number] systems, eliminating duct noise and over-pressurization callbacks.
- Supported retro-commissioning on [number] buildings by testing sensors, actuators and sequences against design intent, identifying [number] faults that were wasting energy.
Customer Service, Leadership and Business Impact
- Trained [number] apprentices on gauge reading, brazing and electrical troubleshooting, and coached them through exam preparation so [number] earned their first certification on the first attempt.
- Supervised a crew of [number] technicians across [number] concurrent installation and service jobs, keeping [X]% of projects within budget and on schedule.
- Presented good-better-best repair and replacement options with photos and readings, raising average service ticket value by [X]% while keeping customer satisfaction scores at [X].
- Developed a standardized startup and handoff checklist for the installation team, reducing warranty callbacks by [X]% over [number] months.
- Served as the escalation point for [number] difficult diagnostic calls per month, resolving problems that other technicians had visited [number] times without a fix.
- Documented findings, readings and photos in field service software at each stop, shortening invoice turnaround from [X] days to [Y] days and improving billing accuracy.
