HVAC Technician resume example

• Entry level

  EPA Section 608 Universal certified HVAC technician and recent graduate of a 9-month HVAC/R program, with 600 hours of ride-along time on residential splits and heat pumps. Checks superheat and subcooling, brazes with a nitrogen purge and pulls vacuum to 500 microns. Comfortable in hot attics and ready for summer overtime and weekend on-call.

• Mid level

  NATE-certified residential HVAC service technician with six years on split systems, heat pumps, gas furnaces and ductless mini-splits. Runs 5 to 7 calls a day in peak season, keeps callbacks under 4% and sells about 30 maintenance agreements a month by explaining findings clearly. Installs and services R-410A and new A2L equipment.

• Senior

  Commercial HVAC lead technician with fourteen years on rooftop units, VRF systems, air-cooled chillers and building automation. Owns a route of 60 maintenance contracts for schools and medical offices, mentors three junior techs and handles startups on new installs. Cut emergency calls on the route by a third through better coil and belt maintenance.

• Commercial refrigeration

  Refrigeration technician servicing walk-in coolers, freezers, ice machines and reach-ins for restaurants and grocery stores. Diagnoses compressor, defrost and expansion valve faults on night calls, stabilizes temperatures fast to limit product loss, and documents leak repairs under EPA refrigerant management rules. Holds EPA 608 Universal.

• Install lead

  Installation lead who turns sold proposals into clean, code-compliant systems. Plans duct changes from Manual D, finishes most residential changeouts in one day, seals and tests ductwork for leakage, and leaves each homeowner a startup sheet with measured airflow. Runs a two-person crew and catches sizing errors before equipment ships.

• HVAC/R graduate

  Recent HVAC/R certificate graduate with EPA 608 Universal, OSHA 10 and 400 lab hours on heat pumps, gas furnaces and refrigeration trainers. Applying for an install helper or apprentice technician role with a structured ride-along program.

• Military veteran

  Air Force HVAC/R journeyman with six years servicing chillers, air handlers and mission-critical cooling at a base facility. Applying for a commercial service technician role, bringing EPA 608 Universal and experience with work-order systems and preventive maintenance schedules.

• Listing refrigerant certification without the type

  Fix: "EPA certified" leaves the manager guessing. Write "EPA Section 608 Universal" or the specific type, then the refrigerants you have charged. If you hold an A2L or R-410A safety credential, put it next to the 608 line so your refrigerant qualifications read as one block.

• Describing maintenance as "performed PMs"

  Fix: Preventive maintenance fills spring and fall, so make it specific. Give the number of systems on your agreement route, what each visit covered (coil cleaning, capacitor checks, combustion test) and failures you caught early, such as a cracked heat exchanger or a compressor drawing high amps.

• Skipping the diagnostic method

  Fix: Managers want techs who measure before they replace parts. Mention superheat and subcooling, static pressure, temperature split, amp draw and combustion readings, and the tools you use for them. A bullet about checking contactors and capacitors before condemning a compressor shows judgment.

• Leaving out callbacks and agreement sales

  Fix: Residential shops track callbacks, average ticket and maintenance agreements sold. Commercial shops track uptime, response time and contract renewals. Report the ones that apply to you with numbers. One measured result per role tells a service manager more than a long list of equipment brands.

EPA 608 Universal

Put the exact type in your header and under certifications.

NATE certified

List each specialty you passed, with the year, under certifications.

Heat pumps

Count heat pump installs or repairs in one bullet and name defrost or reversing valve work.

Rooftop units

Give the tonnage range and site types on your commercial route.

Refrigeration diagnostics

Show a measured method, such as superheat and subcooling readings, in a repair bullet.

Preventive maintenance

State how many agreement customers or units you maintained and what you found early.

Building automation

Mention schedules you programmed or alarms you answered.

A2L refrigerants

Name R-454B or R-32 work and the A2L training you completed, with its year.

• Diagnosed and repaired 1,150 residential no-cool and no-heat calls over two seasons, keeping 30-day callbacks under 4% of tickets.
• Recovered, evacuated and recharged 210 systems with complete refrigerant logs, meeting EPA Section 608 recordkeeping on every job.
• Replaced 85 aging R-22 systems with high-efficiency heat pumps, sizing each with a Manual J load calculation instead of matching the old tonnage.
• Performed spring and fall maintenance for 400 agreement customers, finding 26 failing components, including cracked heat exchangers, before breakdowns.
• Started up 32 rooftop units at a retail center, verifying airflow, economizer operation and gas pressures before owner handover.
• Installed 120 ductless mini-split heads in a school retrofit, running line sets and condensate drains on evening shifts around occupied classrooms.
• Traced a recurring chiller trip to a failing flow switch in 2 site visits, sparing a hospital client a planned compressor teardown.
• Programmed building automation schedules for 14 office floors, cutting after-hours run time and lowering the client's electric bill about 11%.

• Match the posting's residential, commercial or refrigeration focus

  Check whether the posting is for residential service, commercial RTUs and chillers, refrigeration or install work. Move that setting's role and equipment list to the top, use the posting's equipment names and refrigerants, and drop furnace details for a refrigeration route. Naming the tonnage range they service makes the fit obvious. Tailor your resume to this HVAC posting

• Lead the letter with a repair that saved a system

  Start with one specific call, such as a heat-wave no-cool fixed with a capacitor instead of a new condenser, and what it meant for the customer. Then connect it to the company's service area or maintenance plans. State your 608 type, NATE specialties and when you can start. Write an HVAC technician cover letter

• Practice explaining the refrigeration cycle out loud

  Interviewers often ask you to walk through the refrigeration cycle, read a set of pressures or explain why a heat pump ices up. Some shops hand you a meter and a training unit with a planted fault. Rehearse a clear diagnostic sequence out loud, from customer complaint to repair. Prepare for HVAC interview questions

• List equipment by type and size, not brand

  Brands change from shop to shop; equipment types carry over. Group your experience by system type and size, such as 2 to 5 ton splits, 7.5 to 25 ton RTUs or 150 ton chillers. Then compare the posting with your draft to see which equipment terms you missed. Match your HVAC resume to the posting's equipment terms
