Technical Support Engineer (HVAC/AirCon)

Job description

We’re looking for a technically curious, hands-on engineer to join our growing Technical Department, supporting market-leading HVAC and controls solutions across the UK.

This is a varied, field-facing role where no two days are the same — combining technical problem-solving, supplier collaboration, site work, and customer support.

What you’ll be doing

• Based from our Hemel Hempstead office, with regular travel across the UK (and occasional overnight stays)
• Acting as a key technical link with our main suppliers — Samsung, Toshiba, and Mitsubishi Electric
• Attending manufacturer training courses and update meetings
• Staying up to date with product applications, diagnostics, and best practice
• Providing expert technical support on a wide range of systems, including:
• Air & water sourced (H)VRF systems
• Chillers
• Air-to-water heat pumps
• Heat recovery ventilation
• Split systems
• Local and central control systems & accessories
• BMS interfacing and bespoke control panels
• Supporting colleagues, contractors, and consultants via:
• Telephone and email support
• Technical training sessions
• Site visits for commissioning, fault-finding, and troubleshooting
• Completing commissioning documentation and producing clear, detailed site visit reports
• Maintaining an up-to-date technical library of manuals, software, and hardware tools

What we’re looking for

• A reliable, professional engineer with a strong technical mindset
• Comfortable working:
• On construction sites
• At height
• Outdoors and in varied environments
• Flexible approach to working hours to meet customer and project requirements
• Strong communication skills — confident dealing with colleagues, clients, and suppliers
• A practical problem-solver with good computer literacy (Microsoft Office and manufacturer diagnostic tools)
• Willingness to learn — training provided

Requirements

• Full UK driving licence and own vehicle
• Valid passport
• Appropriate CSCS card
• Ability to travel and stay away from home when required
