HVAC CV Examples & Writing Guide
Updated 23 June 2026
An HVAC CV in the UK must immediately tell a recruiter which type of HVAC work you do, installation, service and maintenance, or design, and which certifications you hold to do it legally. This guide shows you how to structure your CV around the tickets, systems and metrics that matter, with real examples for install, service and design roles.
Hvac CV examples
Junior HVAC Installation Engineer
entryLeads with apprenticeship pathway and F-Gas Category I, then demonstrates hands-on VRF and heat-pump experience with measurable first-time fix rates.
HVAC Service & Maintenance Engineer
midHighlights BMS controls literacy (BACnet, Trend), first-time fix and PPM completion metrics, and the breadth of commercial systems (chillers, AHUs, VRF) that signal mid-level competence.
Senior HVAC Design Engineer
seniorFrames experience around building-services design (load calculations, CAD, energy modelling) rather than install/service tickets, with leadership, project scale and net-zero retrofit credentials.
How to write a hvac CV
CV format and length
Keep your HVAC CV to two pages. Use reverse-chronological order: most recent role first. For install and service roles, lead with a compact Certifications block immediately below your contact details, F-Gas, Gas Safe, NVQ/SVQ level, MCS, CSCS, because site access and legal compliance are screened before experience. For design roles, lead with your personal statement and degree, then skills.
What to include in each section
| Section | Install/Service roles | Design roles |
|---|---|---|
| Personal statement | Role specialism (domestic/commercial, install/service), key certifications (F-Gas, Gas Safe, MCS), years of experience, system types | Engineering discipline, project scale, design tools (CAD, energy modelling), chartership |
| Certifications | High on page: F-Gas category, Gas Safe (with ACS codes), NVQ/SVQ level, MCS, CSCS, manufacturer training | Lower priority: CEng, MCIBSE, BREEAM Assessor |
| Skills | System types (VRF, AHU, chillers, MVHR), BMS platforms (BACnet, Trend), refrigerant handling, pipework, controls | Design software (AutoCAD, Revit MEP, IES VE), load calculations, BREEAM/Passivhaus, heat-pump integration |
| Experience | Achievement bullets with metrics: first-time fix rate, downtime reduction, energy savings, PPM completion | Project scale, design leadership, energy performance vs baseline, BREEAM ratings |
| Education | Apprenticeship pathway (Level 2/3 NVQ, City & Guilds), GCSEs if early-career | MEng/BEng in Mechanical or Building Services Engineering |
Certifications: what goes where
For install and service CVs, create a standalone Certifications section right after contact details. List:
- F-Gas (state your category: Category I for full install/service is the gold standard)
- Gas Safe registration number and ACS codes (CODNCO1, CIGA1, etc.) if you work on gas appliances
- MCS certification or pathway status (critical for heat-pump grant-eligible work)
- NVQ/SVQ level and awarding body (Level 3 Diploma in Refrigeration, Air Conditioning and Heat Pump Systems, etc.)
- CSCS/SKILLcard and colour (Green, Gold)
- Manufacturer training (Daikin, Mitsubishi, Trane) if relevant
Include expiry dates for time-limited certifications (F-Gas, Gas Safe). Employers verify Gas Safe numbers online, so accuracy matters.
For design CVs, certifications like CEng, MCIBSE and BREEAM Assessor belong in an Achievements or Professional Memberships section lower down.
Skills: be specific about systems and controls
Don't write "HVAC systems experience." Name the exact equipment and protocols:
- System types: VRF/VRV multi-splits, chillers, AHUs, MVHR units, ductwork, heat pumps (air-source vs ground-source)
- BMS platforms: BACnet, Modbus, LonWorks, Trend, Tridium/Niagara
- Refrigerant work: recovery, leak testing, charging, brazing
- Design tools (for design roles): AutoCAD, Revit MEP, IES VE, EnergyPlus
ATS filters and recruiters search for these exact terms. The mix of systems signals whether you work domestic or commercial scale.
Personal statement examples
Commercial HVAC service engineer with five years maintaining chillers, AHUs, VRF systems and BMS controls across office, retail and healthcare sites. F-Gas Category I and Gas Safe (CODNCO1, CIGA1) certified. Proven track record in reducing system downtime, improving first-time fix rates and delivering planned preventative maintenance to schedule.
Hard-working HVAC engineer looking for a new role to use my skills and grow my career. Experienced in all aspects of heating, ventilation and air conditioning. A team player who is passionate about delivering excellent service to customers.
Writing your experience
Write achievement bullets, not duty lists
HVAC recruiters want to see the metrics the trade actually tracks: first-time fix rate, system downtime reduction, energy savings, PPM completion rate, and call-outs cleared per shift. A bullet that says "responsible for maintenance" is filler. A bullet that says "achieved 92% first-time fix rate across 42 commercial systems, reducing downtime by 28%" is evidence.
Before and after examples
| Weak (duties) | Strong (results + metrics) |
|---|---|
| Responsible for servicing HVAC systems | Serviced 42 commercial HVAC systems (chillers, AHUs, VRF units), achieving a 92% first-time fix rate and reducing average downtime by 28% |
| Installed air conditioning units | Installed 38 air-source heat pumps with a 95% first-time commission rate, supporting MCS-certified grant-eligible work |
| Carried out planned maintenance | Delivered 98% PPM completion rate across a 220-unit portfolio, ensuring compliance with FM contract SLAs |
| Worked on BMS controls | Diagnosed and resolved BMS faults via Trend and BACnet interfaces, cutting call-out response time by 35% through remote diagnostics |
Action verbs for HVAC roles
Install roles: Installed, commissioned, tested, brazed, wired, balanced, handed over
Service roles: Serviced, diagnosed, repaired, recovered, recharged, optimised, responded, maintained
Design roles: Designed, specified, modelled, calculated, coordinated, led, delivered, achieved (BREEAM rating / energy target)
Name the systems you worked on
Don't say "worked on HVAC equipment." Say "serviced VRF multi-split systems, AHUs and water-cooled chillers." Recruiters and ATS filters search for these exact system types, and the mix signals commercial vs domestic scale and the complexity of the work.

Apprenticeships and NVQ/SVQ pathways
If you came in via an apprenticeship or are early-career, name the exact route and level:
- Level 3 Diploma in Refrigeration, Air Conditioning and Heat Pump Systems
- Level 2/3 NVQ in Heating and Ventilation
- Scottish SVQ / Welsh NVQ equivalents
The pathway tells employers which systems you're signed off to touch. A bare "qualified HVAC engineer" doesn't.
Include your GCSEs if you're within five years of finishing school, especially Maths and a science (Physics, Engineering). After that, drop them unless you have no higher qualifications.
Certifications that unlock work
F-Gas is non-negotiable for any refrigeration, air-con, heat-pump or chiller work. It's a legal requirement to handle fluorinated refrigerants. State your category (Category I for full install/service) and expiry date.
MCS certification (or being on the MCS pathway) unlocks the government heat-pump grant (£7,500 per install) for employers. If you're MCS-certified or training toward it, call it out near the top. Distinguish air-source vs ground-source experience explicitly.
Gas Safe registration (with ACS codes like CODNCO1, CIGA1) is required for gas appliances. Include your registration number, employers verify it online.
Manufacturer training (Daikin, Mitsubishi, Trane, Carrier) signals you can work on specific equipment and access warranty support. List it if you have it.
Design-role qualifications
For HVAC design / building-services roles, you need:
- MEng or BEng in Mechanical Engineering or Building Services Engineering
- Chartered Engineer (CEng) status and MCIBSE membership (for senior roles)
- BREEAM Assessor or Passivhaus Designer credentials (if you work on low-energy buildings)
These design CVs read more like an engineering CV than a trades ticket-list. Don't mix the two templates.
Common mistakes to avoid
Listing a single "HVAC" blob that hides which refrigerant categories, gas appliances and system types you're actually certified and competent on.
Separate your certifications clearly: F-Gas Category I for refrigerants, Gas Safe (with ACS codes) for gas, MCS for heat pumps. Each is a different track, and conflating them makes a recruiter assume you have none of them in full.
Writing "experienced in HVAC systems" without naming the exact equipment (VRF, chillers, AHUs, MVHR, heat pumps).
List the specific systems you've installed, serviced or designed. Recruiters and ATS filters search for these exact terms, and the mix signals commercial vs domestic scale.
Burying F-Gas and Gas Safe certifications in a generic "Certifications" section at the bottom of the CV.
For install and service roles, put a compact Certifications block high on the page, right after contact details. Ticket validity is screened before experience on site-based HVAC roles.
Listing duties instead of impact: "responsible for planned maintenance" or "carried out repairs."
Show outcomes with the metrics HVAC employers track: "Delivered 98% PPM completion rate across 220 units" or "Achieved 92% first-time fix rate, reducing downtime by 28%."
Writing "BMS controls experience" without naming the protocols or platforms you've actually used.
List the exact systems: BACnet, Modbus, LonWorks, Trend, Tridium/Niagara. Even diagnosing faults via a BMS interface is worth calling out, it's what separates HVAC CVs now.
Mixing install/service and design templates, e.g. a design CV that leads with F-Gas and CSCS, or an installer CV that lists AutoCAD but no hands-on system experience.
Install/service CVs lead with certifications and system types. Design CVs lead with engineering degree, CAD/energy-modelling tools, and project scale. Pick the template that matches the role you're applying for.
