For a stable HVAC installer where service and long-term customer relationships come first, we're looking for a Key Account Manager. You are the central point of contact for a fixed portfolio of service customers and combine relationship management with technical coordination. Your goal is simple: customers who are more than satisfied and stay that way.

  • Act as the single point of contact (SPOC) for your customers and all their service questions
  • Coordinate the technicians and handle their dispatch
  • Prepare and follow up the service intake after handover from the project manager
  • Hold regular service meetings with your customers and build thorough knowledge of their installations

  • Spot commercial opportunities, focusing on small jobs and extending existing maintenance contracts

What you bring

  • Experience as an account manager, with an eye for lasting customer relationships
  • Solid basic knowledge of HVAC in a B2B context: components, maintenance cycles and fault reports
  • You don't do the repairs yourself, but you know what it takes to coordinate correctly and advise customers on substance
  • Strong at organising and prioritising in a dynamic service environment
  • Analytical: you track KPIs and see where processes and customer handling can improve
  • You communicate clearly, professionally and with a solution focus, with customers and internal teams

What you get

  • A full-time contract with an attractive salary package in line with your experience
  • Company car, laptop and smartphone with subscription

  • Option of bike leasing and training
  • 20 days off plus 12 ADV days, following the construction holiday
  • Trust and room to manage your customer portfolio independently
