What WKZ Totaalinstallateur does

WKZ Totaalinstallateur is a Dutch total installation company headquartered in Apeldoorn, Netherlands, operating since 1985. The company delivers integrated climate control, HVAC, electrical, and energy solutions across the full project lifecycle — from design and engineering through installation to ongoing maintenance. Its core technical capabilities span heat pumps, air conditioning, ventilation with heat recovery, solar panel systems, industrial cooling technology, custom air handling, and electrical engineering (delivered through subsidiary WVM Elektrotechniek), with a stated focus on sustainable and energy-efficient installations.

The company serves four primary customer segments: commercial/business, government/institutional, residential/consumer, and industrial/manufacturing, and is actively engaged across verticals including healthcare, hospitality, childcare, retail, office, laboratory, manufacturing, agriculture, automotive, and heritage buildings. It operates as a sales-led, direct-to-customer installer pursuing projects through field sales, technical consultations, and competitive bidding, supported by 24/7 emergency service availability. Revenue is generated through one-time installation projects, equipment sales of A-brand manufacturer products (Daikin, Mitsubishi Electric, Panasonic), and recurring maintenance contracts.

The business is family-owned and operated, having transitioned leadership in 2023 from founder-director Cees van Dongen to his sons Max and Sam van Dongen. WKZ employs approximately 50 people across offices in Apeldoorn and Amsterdam, holds relevant industry certifications (PED, STEK, BRL 6000-25), and maintains memberships in NVKL and Techniek Nederland. It has been recognized through the Daikin Awards in 2019 (Smart Building category) and 2023.
