Overview
HVAC (heating, ventilation, and air conditioning) is one of the fastest growing sectors in UK building services. New energy efficiency regulations, the push toward heat pumps, and the growing demand for cooling in commercial buildings mean there are more trainee positions than qualified engineers to fill them. But the barrier to entry is specific qualifications: an F-Gas certificate, a refrigeration handling licence, and ideally a Level 2 or 3 qualification in refrigeration and air conditioning.
This resume belongs to Owen Marsh, who completed a Level 3 Diploma in Refrigeration, Air Conditioning, and Heat Pump Systems at Eastleigh College and holds a Category 1 F-Gas certificate. He has 8 months of experience with a commercial HVAC contractor, servicing split systems, VRV units, and chilled water plant in office buildings and retail units across Hampshire.
What Makes This Resume Work
The F-Gas certificate is prominent. Owen's Category 1 F-Gas certificate allows him to handle all quantities of fluorinated greenhouse gases. This is a legal requirement for anyone who installs, maintains, or services refrigeration and air conditioning equipment containing F-Gas refrigerants. Without it, he cannot touch the refrigerant circuit. By listing it in both his summary and certifications, he removes any doubt about his legal compliance.
Equipment types are named specifically. Rather than writing "serviced air conditioning units," Owen lists the specific systems he has worked on: Daikin VRV IV split systems, Mitsubishi Electric ceiling cassettes, Carrier chilled water AHUs, and Samsung DVM S heat recovery systems. HVAC employers recruit for brand familiarity because each manufacturer has different control systems, fault codes, and service procedures.
Service numbers give volume. Owen has completed 65 planned preventative maintenance (PPM) visits, replaced 12 compressors under supervision, and recharged refrigerant on 28 systems. He has also assisted with 4 new VRV installations from scratch, including pipework brazing, vacuum testing, and commissioning. These numbers show that he is not just watching; he is doing the work.
The heat pump experience is forward looking. Owen completed a module on air source heat pump installation and has assisted with 3 domestic ASHP installations. With the UK government pushing heat pumps through the Boiler Upgrade Scheme, this experience positions him for the growing residential market alongside his commercial HVAC skills.
Key Takeaways
Lead with your F-Gas certificate category. It is a legal requirement and the first thing HVAC employers check. Category 1 covers all equipment; Category 2 is limited.
Name the brands and system types you have worked on. Daikin, Mitsubishi, Carrier, Toshiba, Samsung. Brand experience matters in HVAC because training and diagnostic tools are manufacturer specific.
Include your PPM count, your commissioning experience, and any refrigerant handling you have done. The more specific your numbers, the easier it is for an employer to assess your readiness for independent work.
