HVAC Technician CV Examples
Updated 9 July 2026
A strong HVAC technician CV proves you can install, service and fault-find on the systems UK employers need, and that you hold the certifications to do it legally. This guide shows you how to write a CV that wins refrigeration, air conditioning and heat-pump roles in 2026, with real examples and the metrics that matter.

How to write a hvac technician CV
Your HVAC technician CV should run to two pages in reverse-chronological format: contact details and personal statement at the top, then skills, experience, education and certifications. Keep it factual, specific and compliance-focused, HVAC employers screen for legal qualifications and measurable service delivery before they interview.
What to include in each section
| Section | What to include |
|---|---|
| Personal statement | 2–3 sentences: your F-Gas category, years of experience, the systems you work on (e.g. chillers, VRF, heat pumps), and your standout metric (first-time-fix rate, site count, or specialism). |
| Skills | 6–8 role-specific technical and customer-service skills: system types, fault diagnosis, brazing, electrical work, BMS controls, refrigerant handling. Skip generic soft skills. |
| Experience | Reverse-chronological roles with 3–4 achievement bullets each. Lead with action verbs (installed, commissioned, diagnosed, serviced) and quantify every claim (number of sites, first-time-fix %, callout response time, plant capacity). |
| Education | Your City & Guilds or NVQ qualifications, most recent first. Note if you completed a time-served apprenticeship, it's a key signal. |
| Certifications | F-Gas (state the category and awarding body), 18th Edition, heat-pump training, CSCS, BMS controls. Date them and name the issuer. |
| Additional info | Full UK driving licence (note points if any), IPAF, working at height, asbestos awareness. Only include what's relevant to HVAC field work. |
Tailor to the environment
HVAC employers hire for a specific environment: commercial offices, industrial plant, hospitals, data centres, supermarkets, or domestic. Name the environments you've worked in and the scale of plant (e.g. "chillers 50–200 kW", "30-site retail service round"). A supermarket-refrigeration tech and a domestic heat-pump installer are different hires, make it clear which you are.
Personal statement examples
F-Gas Category 1 certified HVAC technician with four years' experience servicing and fault-finding on commercial air conditioning, chillers and air-source heat pumps. Proven track record maintaining 92% first-time-fix rate across a 45-site service round. Skilled in BMS controls, electrical fault-finding and customer-facing service delivery.
Hard-working and reliable HVAC technician looking for a new role to use my skills and grow. Passionate about heating and cooling systems. Good team player with a positive attitude and strong work ethic.
Writing your experience
HVAC employers want to see the install/maintain/fault-find triad and the systems you've touched. Every bullet should follow the pattern: action verb + system/task + quantified result. Lead with what you did (installed, commissioned, diagnosed, serviced, repaired), name the equipment (VRF, chiller, heat pump, AHU, compressor), and close with a number that proves impact.
Before and after examples
| Weak (duties list) | Strong (action + system + metric) |
|---|---|
| Responsible for servicing air conditioning systems. | Serviced VRF and split AC systems across 30 commercial sites, achieving 91% first-time-fix rate and reducing reactive callouts by 22%. |
| Carried out planned maintenance on refrigeration equipment. | Maintained commercial refrigeration (walk-in cold rooms, display cabinets) in 12 supermarket sites, reducing average reactive callouts by 18% through proactive component replacement. |
| Installed heat pumps for clients. | Installed and commissioned 14 air-source heat pumps (8–16 kW) for commercial retrofit projects, meeting MCS standards and delivering full handover documentation. |
Action verbs for HVAC roles
Installed, commissioned, diagnosed, serviced, repaired, maintained, fault-found, programmed (BMS), recovered (refrigerant), recharged, brazed, wired, tested, inspected, optimised, mentored, led, delivered.
Show the triad
For each system type, signal whether you did installation, planned/reactive maintenance, or fault-finding, these are distinct skill signals. A senior tech will show all three; a junior might lead with install and planned maintenance. Also note whether you worked on the mechanical side (pipework, brazing, refrigerant), the electrical side (wiring, commissioning, fault-tracing), or both.
Prove compliance and documentation
HVAC service roles explicitly screen for safety and compliance discipline. Show that you produce accurate service reports, risk assessments, method statements, and refrigerant-handling records. Mention HSE compliance, F-Gas record-keeping, working at height, and any audit results (e.g. "100% audit compliance across client quality reviews").
Key skills & ATS keywords

Education & certifications
List your UK trade qualifications prominently: City & Guilds in plumbing/heating or refrigeration & AC, NVQ Level 2/3 in Building Services, and whether you completed a time-served apprenticeship. "Time-served apprentice or equivalent" is the phrase many UK HVAC job specs use, mirror it in your education notes if you did a full apprenticeship.
F-Gas certification
State your F-Gas certification category explicitly: F-Gas Category 1 (City & Guilds 2079) is full installation/servicing/decommissioning of all refrigeration and AC systems. Categories 2–4 are progressively more limited. UK employers can't legally let you work on RACHP systems without it, so an unstated or vague "F-Gas certified" line costs you.
City & Guilds F-Gas certification is valid for life (no renewal required), but still date it and name the awarding body. If you hold the older CITB route (pre-2015), say so, CITB no longer issues new certificates, so it signals time-served experience.
Electrical qualifications
List your electrical competence: 18th Edition Wiring Regulations (BS 7671:2018+A2:2022) is the baseline. If you hold Inspection & Testing (City & Guilds 2391) or Part P, add those, HVAC technicians wire and commission units, so electrical credentials separate you from install-only engineers.
Heat pumps and renewables
Heat pumps (air-source and ground-source) are a fast-growing demand area as the UK pushes net-zero. Call out any heat-pump installation & commissioning training (e.g. Logic4Training, MCS standards) and note if you're familiar with refrigerant-transition work (phasing out high-GWP gases like R404A in favour of R32, R454B). This is a current differentiator.
BMS controls
BMS/controls familiarity (e.g. Trend IQ Vision, Tridium Niagara, Schneider EcoStruxure) is a high-value, role-specific line for service and senior roles. If you've completed formal BMS training, list it.
Site access and safety
- CSCS card (Green Labourer or Gold Skilled Worker), many construction sites won't admit you without one.
- IPAF 3a & 3b (mobile elevated work platforms), common for AC and AHU work.
- Working at Height (PASMA), often required for ductwork and rooftop plant.
- Asbestos Awareness (UKATA), relevant for older commercial buildings.
- Confined Spaces (CS1), relevant for plant rooms and industrial sites.
Driving licence
A full UK driving licence is effectively mandatory for mobile/field HVAC roles. State it in the "Additional info" section and note if it's clean or how many points you have ("no more than 6 points" is the common threshold).
Common mistakes to avoid
Using a vague job title like "HVAC Installer" or "Heating Engineer" without naming the systems you work on.
Be specific: "HVAC Technician – VRF/VRV Air Conditioning, Chillers & Heat Pumps" or "Refrigeration & AC Service Engineer". Generic titles read as junior.
Stating "F-Gas certified" without the category or awarding body.
Write "F-Gas Category 1 (City & Guilds 2079)" and date it. Employers can't legally let you work on refrigeration or AC systems without knowing your category.
Listing duties instead of quantified achievements: "Responsible for servicing air conditioning systems."
Show the result: "Serviced VRF and split AC systems across 30 commercial sites, achieving 91% first-time-fix rate and reducing reactive callouts by 22%."
Padding the skills section with generic soft skills ("team player", "hard-working", "good communicator") instead of HVAC-specific technical skills.
Keep it tight and role-specific: refrigeration/AC systems, fault diagnosis, brazing, electrical fault-finding, BMS controls, refrigerant recovery. Both technical and customer-service skills matter, but lead with the technical.
Failing to state the environment or scale: "Worked on air conditioning systems" tells an employer nothing.
Name the environment (commercial offices, hospitals, data centres, supermarkets, domestic) and the scale (e.g. "chillers 50–200 kW", "45-site service round", "12 retail units").
Omitting your driving licence or CSCS card, both are often deal-breakers for field roles.
List "Full UK driving licence (clean, no points)" and your CSCS card type in the "Additional info" section.
