HVAC / AC Technician resume

An HVAC or AC technician resume should include the types of systems you work on, your refrigerant handling and other certifications, your diagnostic and maintenance skills, and bullets with the buildings, equipment and results of your work. Employers want to know immediately whether you handle split units, VRF systems, chillers or commercial rooftop units.

Core sections:

• Header: name, "HVAC Technician" or "AC Technician", phone with country code, email, city, driving licence if you drive between sites.
• Summary: years, system types and sector.
• Certifications and licences, with expiry dates.
• Skills: installation, troubleshooting, refrigerant recovery and charging, electrical controls, preventive maintenance.
• Experience with bullets.
• Training or diploma.

Example summary (fictional): "HVAC technician with six years servicing VRF systems, FCUs and AHUs in commercial towers, specialising in fault diagnosis and planned maintenance."

Keep it to one or two pages in a simple layout.

In three lines, state your years, the equipment you know best, your setting (residential, commercial, industrial) and a strength such as fast diagnosis or energy savings. Be specific about systems, because that is what HVAC employers screen for.

Example summaries (fictional):

• Commercial: "HVAC technician with eight years maintaining chillers, AHUs and FCUs in hospitals and malls. Skilled in troubleshooting controls and keeping critical areas within temperature limits."
• Residential: "AC technician with five years installing and servicing split and ducted units in villas and apartments, known for clean installs and clear explanations to customers."
• Entry level (fictional): "HVAC trainee with a diploma in refrigeration and air conditioning and six months assisting with split-unit servicing."

Add your main certification at the end if it is a common requirement in your market.

List every recognised certification you hold, with the issuing body and expiry date, in a section near the top. Commonly seen examples include EPA Section 608 certification in the US, F-gas certificates in the UK and EU, NATE certifications, manufacturer training (for example on VRF or chiller brands), and your national trade certificate in refrigeration and air conditioning.

Example format (fictional):

• "Refrigeration and Air Conditioning Trade Certificate – National Technical Board, 2019."
• "F-gas Category 1 certificate – 2022" (UK/EU example).
• "VRF installation and service training – [manufacturer], 2023."

Requirements for handling refrigerants and doing HVAC work differ between countries. If your local authority requires a licence or certificate, list it exactly as issued, with its number and expiry, and check the job advert for what the employer asks for.

Good AC technician bullets name the equipment, the task and the outcome. These fictional examples show the style; adapt every detail to your work:

• Example: "Installed and commissioned 150 split and cassette units in a residential community, including vacuuming, charging and leak testing."
• Example: "Diagnosed compressor, capacitor and sensor faults on VRF systems, restoring cooling on the same visit in most cases."
• Example: "Carried out quarterly PPM on 60 FCUs and 8 AHUs, cleaning coils, changing filters and checking belts."
• Example: "Recovered and recharged refrigerant following safe handling procedures and recorded quantities in the log."
• Example: "Explained faults and maintenance tips to residents, reducing repeat calls."

Avoid writing only "repaired air conditioners". Mention the system type and scale to show your real level.

Include the equipment, procedures, tools and controls you can handle confidently, grouped for easy scanning.

Skill groups:

• Equipment: split, ducted, cassette, VRF/VRV, package units, chillers, AHUs, FCUs, cooling towers.
• Refrigeration: recovery, evacuation, charging, brazing, leak detection, superheat and subcooling checks.
• Electrical: reading wiring diagrams, contactors, capacitors, thermostats, VFDs.
• Controls: BMS basics, thermostats, sensors.
• Air side: duct installation, balancing, filter changes, IAQ.
• Tools: gauges, vacuum pumps, leak detectors, multimeters, anemometers.

Example skills line (fictional): "VRF servicing | Refrigerant recovery and charging | Brazing | Electrical fault-finding | BMS alarms | Air balancing."

Only list items you could demonstrate on a practical test.

Count what you maintained, repaired and improved, and note response times, uptime and energy or comfort improvements you can explain. Numbers turn a list of duties into proof of good work.

Ideas:

• Volume: units installed, PPMs completed, buildings covered.
• Response: average time to restore cooling, calls closed per day.
• Uptime: chillers or critical areas kept running.
• Improvements: energy-saving changes, fewer complaints.
• Quality: first-time fixes, low call-backs.

Example bullets (fictional):

• "Closed an average of seven service calls per day across residential buildings."
• "Cleaned and re-balanced the air side of an office floor, resolving long-standing hot-spot complaints."
• "Kept server room cooling running through summer with weekly checks and standby rotation."

Only use figures from your own records or honest estimates.

Residential resumes focus on split and ducted units, customer service and independent work; commercial resumes focus on larger central systems, controls, planned maintenance and teamwork. Tailor your summary and first bullets to the job.

Residential focus:

• Split, ducted and window units.
• Installation in homes, clean work, explaining issues to customers.
• Fast diagnosis on service calls.

Commercial focus:

• VRF, chillers, AHUs, FCUs, cooling towers.
• BMS alarms and controls.
• PPM schedules, CMMS work orders, contractor coordination.

Example residential bullet (fictional): "Installed ducted units in 30 villas, sealing ducts and testing airflow in each room."
Example commercial bullet (fictional): "Responded to BMS alarms on AHUs in a hospital, fixing faulty actuators and sensors."

Put your diploma and practical training first, then any internship or assistant work, plus the tools and safety training you have. Employers hiring trainees look for basic knowledge, safe habits and willingness to learn.

What to include:

• Summary: "Refrigeration and AC diploma holder seeking a trainee or assistant technician role."
• Education: diploma name, institute and year, with key practical modules (brazing, refrigerant handling, electrical controls).
• Internship or on-the-job training with bullets.
• Certifications you hold.
• Skills you can perform without help.

Example bullets (fictional):

• "Assisted technicians with split-unit installation and gas charging during a three-month internship."
• "Cleaned filters and coils on 40 indoor units under supervision."

Keep it to one page.

Emphasise complex equipment, leadership, planning and results: chillers and central plants, team size, PPM programmes, contractor management and energy or uptime improvements.

Points to include:

• Central plant: chillers, cooling towers, pumps, BMS.
• Team: technicians and helpers you lead or train.
• Planning: PPM schedules, spare parts, shift rosters.
• Contractors: specialist service providers you coordinate.
• Reporting: monthly reports to facility managers.

Example bullets (fictional):

• "Led a team of six HVAC technicians covering three commercial towers, scheduling PPM and reactive work."
• "Coordinated annual chiller overhauls with the manufacturer's service team."
• "Introduced a spare-parts list for critical units, cutting waiting time for repairs."

Keep a short line on hands-on diagnostics, as many supervisors still troubleshoot.

Name the chiller types, capacities if known, the tasks you performed and whether you worked alone or with the manufacturer. Chiller experience is a strong skill in commercial HVAC and district cooling.

Points to include:

• Chiller types: air-cooled, water-cooled, screw, centrifugal.
• Tasks: daily log readings, start-up and shutdown, oil and refrigerant checks, tube cleaning.
• Related plant: cooling towers, pumps, heat exchangers, water treatment coordination.
• Controls: BMS sequences and alarms.

Example bullets (fictional):

• "Recorded daily operating logs for four water-cooled chillers and reported abnormal readings to the plant engineer."
• "Assisted the manufacturer's team with annual condenser tube cleaning and oil analysis."
• "Rotated duty and standby chillers weekly to balance running hours."

Say "assisted" where the main work was done by a specialist.

Use the HVAC terms from the job advert that truly match your work, such as HVAC, air conditioning, VRF, chiller, AHU, FCU, split units, refrigerant recovery, charging, brazing, troubleshooting, preventive maintenance, PPM, BMS, ductwork, commissioning and indoor air quality.

How to use them:

• Note repeated words in two or three adverts.
• Put them in your summary, skills and the first bullets of your latest job.
• Write the full form once for abbreviations: "air handling units (AHUs)".
• Never copy the advert or list skills you lack.

Example bullet (fictional): "Performed PPM on AHUs and FCUs and responded to BMS alarms in a 30-floor office tower."

A job-description comparison can show which frequent advert terms are missing from your resume.

Avoid vague duty lists that do not say which systems you work on; "maintained air conditioners" could mean a window unit or a chiller plant. Name the equipment and scale.

Other mistakes:

• Missing certifications or listing them without years or issuing bodies.
• Claiming refrigerant handling or electrical work you are not certified for.
• Using an engineering title when your role was technician.
• Listing every hand tool instead of key skills.
• Leaving out driving licence when the job involves travel between sites.
• Using two-column designs that are hard to read on online forms.

Quick fix: add the system and building type to each bullet. Example (fictional): "Replaced faulty expansion valves on VRF indoor units in a hotel, restoring room temperatures."

Show heavy cooling-season experience, the systems common in the region (split, VRF, chillers, district cooling), your trade certificate, availability and, if relevant, visa status and driving licence.

Tips:

• Mention the building types: villas, towers, malls, hospitals.
• Show you can handle peak summer demand: call volumes, standby rotations.
• List any local authority approvals exactly as issued.
• Add languages spoken with customers and teams.

Example bullets (fictional):

• "Handled up to 10 summer service calls per day across residential communities in Dubai."
• "Serviced VRF systems and FCUs in a Riyadh office tower under a facilities management contract."

Use a clean A4 resume of one to two pages, and make sure your phone number includes the country code.

Yes, if you are trained and, where required, certified to handle refrigerants, because it is a core HVAC skill and many employers ask for it. Be precise about what you do.

What to mention:

• Recovery, evacuation and charging.
• Refrigerant types you work with, in general terms.
• Leak detection and repair.
• Record keeping of quantities used and recovered.

Example bullets (fictional):

• "Recovered refrigerant before compressor replacement and recharged by weight to manufacturer specifications."
• "Kept refrigerant logs for each unit as required by company procedures."

List your refrigerant certification, if you have one, in Certifications. If you are not certified, do not claim to handle refrigerants yourself; describe the tasks you assisted with instead.

Describe the systems installed, your part in the installation, the tests you ran and how the system was handed over. Installation and commissioning skills are valued on construction and fit-out projects.

Points to include:

• Unit and duct installation, copper piping, drain lines.
• Pressure testing, vacuuming and charging.
• Start-up checks, airflow measurement and balancing.
• Commissioning sheets and handover to facilities.

Example bullets (fictional):

• "Installed VRF outdoor units, refrigerant piping and indoor cassettes for a 12-floor office building."
• "Pressure-tested and vacuumed all refrigerant lines and recorded results on commissioning sheets."
• "Supported air balancing with the testing and commissioning contractor before handover."

Describe what you actually do with the BMS: responding to alarms, adjusting setpoints, checking sensors or replacing controllers. Avoid claiming programming skills unless you program controllers.

Examples (fictional):

• "Monitored the BMS for AHU and chiller alarms and attended faults within the agreed response time."
• "Replaced failed temperature sensors and actuators and verified readings on the BMS."
• "Adjusted schedules and setpoints with the facility manager to reduce out-of-hours running."

In skills, write it accurately: "BMS monitoring and alarms" or "BMS operator". If you have trained on a specific controls platform, add it under Certifications.

Yes. HVAC technicians often move into facilities supervisor, maintenance planner, HVAC estimator or technical sales roles. Rewrite your summary and bullets to highlight the skills the new role needs.

Ideas:

• Facilities: planning PPM, managing contractors, reporting, budgets.
• Estimating or sales: site surveys, load estimates, quoting, customer advice.
• Training: coaching junior technicians.

Example summary for facilities (fictional): "HVAC technician with nine years in commercial buildings, moving into a facilities supervisor role, with experience planning PPM, managing contractors and reporting to building managers."

Example bullet for sales (fictional): "Surveyed homes and recommended suitable AC capacity and layouts, with written quotes for customers."

For most HVAC technicians: header, summary, certifications, skills, work experience, training, languages. Certifications come early because refrigerant and trade certificates are checked first.

Example order:

• Header with name, title, phone, email, city, driving licence.
• Summary in three lines.
• Certifications and licences with expiry dates.
• Skills grouped by equipment, refrigeration, electrical, controls.
• Work experience, latest first.
• Diploma or trade training.
• Languages.

For freshers, move training and diploma above experience. Use a single column so online systems read it correctly.

Describe the change you made, how you checked it worked and the benefit, without claiming savings you cannot show. Energy and IAQ work is increasingly valued by building owners.

Examples of improvements:

• Cleaning coils and changing filters on schedule.
• Fixing faulty sensors or dampers.
• Adjusting schedules and setpoints.
• Upgrading to more efficient units, under supervision.

Example bullets (fictional):

• "Fixed stuck outside-air dampers on AHUs, improving fresh-air supply to office floors."
• "Worked with the facility manager to adjust running schedules, reducing out-of-hours operation."
• "Introduced a filter change log that helped keep air quality complaints low."

If the building measured savings, you can mention them; otherwise describe the change.

Yes, list the electrical tasks you perform on HVAC equipment, because many faults are electrical and employers want technicians who can diagnose them. Be honest about the scope.

Skills to mention if true:

• Reading HVAC wiring diagrams.
• Testing and replacing capacitors, contactors, relays and fuses.
• Checking motors and compressors with a multimeter or clamp meter.
• Working with thermostats and controllers.

Example bullet (fictional): "Diagnosed failed contactors and capacitors on rooftop units using a multimeter and replaced them safely after isolation."

If your country requires a separate electrical licence for certain work, do not claim that work unless you hold it. List any such licence as your local authority requires.

Show how you diagnosed problems, explained them to customers and left them satisfied. For residential and small commercial service roles, communication matters as much as technical skill.

Example bullets (fictional):

• "Explained faults and repair options clearly to homeowners and gave written estimates before starting work."
• "Kept homes clean with floor covers and removed old parts after each job."
• "Received regular positive feedback from customers in the company's service survey."
• "Advised customers on filter cleaning and thermostat settings to avoid repeat calls."

Add "customer communication" to your skills, but let these bullets prove it.

Yes, if ductwork is part of your job, because some HVAC roles focus on air distribution rather than refrigeration. Make it clear whether you fabricate, install or only repair ducts.

Points to include:

• Duct fabrication or installation (sheet metal, pre-insulated panels, flexible ducts).
• Sealing and insulation.
• Grilles, diffusers, dampers.
• Air balancing support.

Example bullets (fictional):

• "Installed pre-insulated ductwork and diffusers for a 200-seat restaurant fit-out."
• "Sealed leaking duct joints in an office ceiling void, improving airflow to meeting rooms."

If you are a duct fabricator, list the machines or tools you use in your skills line.

List it under Certifications or Training with the manufacturer's name, the system, the year and whether you received a certificate. Manufacturer training is a useful signal, especially for VRF, chiller and controls work.

Example lines (fictional):

• "VRF system installation and servicing training – [Manufacturer], 2023 (certificate)."
• "Screw chiller maintenance course – [Manufacturer], 2022."

Tips:

• Use the official course name if it is on your certificate.
• Do not imply you are an authorised dealer or partner if you only attended training.
• Put the most relevant training first.

Then support it with a bullet: Example (fictional): "Commissioned VRF systems following manufacturer procedures learned in factory training."

Name the facilities company as your employer and add the sites you covered in a short line, then use bullets for your work across them. This makes it clear who employed you and where you worked.

Example entry (fictional):
HVAC Technician – Summit Facilities Services, Abu Dhabi, 2020–2025
Sites: "Two hospitals, a government office complex and a shopping mall."

• "Carried out PPM and reactive maintenance on chillers, AHUs and FCUs across four sites."
• "Logged work orders in the CMMS and met contract response times."
• "Worked closely with client facility managers on monthly reports."

Only name clients or sites that are public or that your employer allows you to share.

Give one or two bullets that walk through a real fault: the symptom, how you diagnosed it and the fix. A short story of a solved problem is more convincing than the word "troubleshooting" in a skills list.

Structure for a troubleshooting bullet:

• Symptom: "Unit tripping on high pressure in peak afternoon heat."
• Diagnosis: readings, tests or inspections you used.
• Fix and result: what you replaced or adjusted and what improved.

Example bullets (fictional):

• "Traced repeated high-pressure trips on a rooftop unit to a failed condenser fan motor, replaced it and restored stable operation."
• "Used superheat and subcooling readings to find an undercharged VRF system, repaired a flare leak and recharged by weight."
• "Found a blocked condensate drain causing ceiling leaks in a hotel corridor and added it to the PPM checklist."

Keep each bullet to one or two lines.
