Hunziker Partner Ag

What Hunziker Partner Ag does

Hunziker Partner AG is a Swiss building services engineering (Haustechnik) company founded in 1932 and headquartered in Winterthur, with a secondary fabrication facility at Lagerplatz 26. The firm provides integrated planning, coordination and realization of sanitary, heating, cooling, climate, air (ventilation) and electrical installations, augmented by a building automation and intelligent-living practice (Gebäudeautomation, SCADA, RFID smart access). Engineering work is delivered through BIM (Building Information Modeling) and CAD-based planning, with Minergie specialist-partner status since 2008 covering over 100,000 m² of certified buildings.

The firm operates a sales-led, project-based go-to-market directly serving architects, private residential owners, and institutional clients (real estate companies, pension funds, healthcare, education, public sector). Revenue is generated through three streams: engineering and planning services (professional services), construction and installation (project execution on behalf of architects and owners), and recurring service and maintenance including 24/7 emergency response, Service-Abonnements, boiler descaling, and water heater replacement. Unit pricing for standardized residential work is publicly disclosed (e.g., bathroom renovations CHF 20,000–60,000; water heater replacement from CHF 7,700), while larger institutional projects are quote-driven and have ranged from CHF 520K to CHF 10M.

The business is a privately held Aktiengesellschaft with 100+ employees, ISO 9001/14001/45001 certified by SQS, Minergie-Fachpartner since 2008, and a recognized Toplehrbetrieb and Swiss Arbeitgeber Award recipient. In May 2023, ownership transitioned from the founding Hunziker family to long-tenured insiders Monika Zemp and Ilyas Oeznalci (50/50), who each have over 35 years at the company and serve as Co-CEO/VRP. Execution is concentrated regionally within ~40 km of Winterthur, while planning and coordination services operate nationally.

Direct peers

• Waldhauser + Hermann AG: Swiss building services firm offering heating, ventilation, sanitary, and cooling installations plus building automation for residential and commercial projects. Comparable mid-sized integrated Haustechnik provider with similar regional Swiss focus.
• Hauri AG: Swiss mid-sized Haustechnik company offering heating, ventilation, sanitary, and cooling services with similar project-based execution and regional focus. Closely comparable to Hunziker in scale, integrated service model, and customer base of institutional and private clients.
• Kummler + Matter AG: Swiss electrical and building services engineering firm providing energy distribution, building automation, and telecommunications infrastructure. Comparable in building-automation and electrical-installation scope, with overlapping institutional clients across Switzerland.
• Haerter + Partner AG: Swiss engineering and consulting firm specializing in building services planning, energy concepts, and facility management consulting. Closely comparable to Hunziker's engineering/planning arm, especially on Minergie-certified and energy-retrofit projects.
• Gruenberg + Partner AG: Swiss Haustechnik engineering and consulting firm delivering integrated HVAC, sanitary, and energy planning. Comparable in scope and customer segment (institutional and commercial building owners), operating as a planning-led counterpart to Hunziker's execution-led model.
• Amstein + Walthert AG: Swiss engineering firm specializing in building services (Heizung, Lüftung, Sanitär, Klima) and electrical engineering with national coverage. Directly comparable to Hunziker as a full-service Haustechnik planner and consultant, though Amstein + Walthert is larger and primarily engineering-led rather than execution-led.

Broad incumbents

• Siemens Smart Infrastructure (Switzerland): Siemens's Swiss division supplying building automation, HVAC controls, and energy-management platforms. Overlaps with Hunziker's SCADA/building-automation offering but as a global OEM/integrator rather than regional service contractor.
• ENGIE Services AG (Switzerland): Subsidiary of global energy and facility-services group ENGIE providing HVAC, building automation, and energy management across Switzerland. Comparable in core HVAC/automation capabilities but operates at much larger scale and as part of a broader multinational portfolio.
• Bouygues Energies & Services Schweiz AG: Swiss arm of the Bouygues group delivering integrated building services, energy solutions, and facility management. Competes with Hunziker for large institutional and commercial Haustechnik contracts but as part of a much wider international services platform.

Emerging players

• Anex Ingenieure AG: Swiss building services and energy engineering firm focusing on sustainable building concepts, Minergie consulting, and HVAC planning. Comparable niche overlap with Hunziker's planning/engineering offerings, particularly on energy-efficient new-builds and retrofits.
