Role guide · HVAC & refrigeration
HVAC engineering spans more temperature than any other trade — brazing at over 600°C before lunch, handling suction lines that frost the skin after it — in workplaces that alternate between plant rooms, rooftops, ceiling voids and someone's reception area. The kit list runs hot, cold and presentable at once.
The job
The hot end: brazing and soldering pipework is genuine hot work — EN 407 gloves, appropriate eye protection (brazing wants tinted lenses; the flame is bright), natural-fibre or FR-appropriate sleeves per the melt rule, and the hot-work-permit discipline of whatever building you're in. The cold end: liquid refrigerant and bare suction lines cause instant cold burns — insulated gloves for charging and recovery, eye protection against spray (a venting valve is a freeze-spray accident), and the F-Gas handling rules that govern the work itself. Deep-freeze plant work borrows the cold-store logic outright.
The places in between shape the everyday kit: stretch trousers with knee protection for ceiling voids and crawl spaces, a bump cap where ducts and steels live at head height, S1P/S3 footwear per site, and rooftop plant brings hi-vis, weather layers and the building's edge-protection regime. The customer-facing layer completes it: HVAC engineers walk through offices and shops to reach their plant rooms, so the doorstep-professional logic — embroidered polos, presentable softshells — applies the moment the van door opens.
The list
| Task | The kit that matters | The spec detail |
|---|---|---|
| Brazing & hot work | EN 407 gloves, tinted eye protection, melt-safe sleeves | Plus the building's hot-work permit rules |
| Refrigerant handling | Insulated gloves, eye protection | Cold burns are instant — F-Gas rules govern the task |
| Voids & crawl spaces | Knee protection, bump cap, fitted kit | EN 812 territory, exactly |
| Rooftop plant | Hi-vis, weather layers, site edge rules | The forgotten outdoor workplace |
| Client premises | Embroidered presentable layer, overshoes | The trade walks through reception to work |
Questions
Heat-rated (EN 407) gloves, eye protection with appropriate shading for the bright flame, non-melting sleeves and clothing, and the venue's hot-work permit controls — fire watch included. It's proper hot work even when it's three joints in a ceiling void.
Yes — cold burns: liquid refrigerant and freshly frosted lines are cold enough to injure skin on contact, and a venting connection sprays. Insulated gloves and eye protection for charging, recovery and any break-into-circuit work are the standing kit, with F-Gas rules governing the task itself.
Stretch trousers with knee-pad inserts (voids and crawl spaces are the office), embroidered polos or softshells presentable enough for client premises, S1P/S3 footwear per site, a bump cap where services run at head height, and hot/cold task PPE in the van for the day's extremes.
