Steger AG

What Steger AG does

Steger AG is a Swiss Haustechnik (building technology) contractor founded in 1927 and headquartered in Aadorf, Canton of Thurgau, with 35 employees and a privately held status as a subsidiary of the Amix AG corporate group (which also owns Büchler and Chromix AG). The company delivers integrated HVAC, sanitary, and renewable energy installation and maintenance services to residential property owners, commercial buildings, and institutional clients, with named reference work at the ETH Zürich / University of Zürich campus served from a dedicated Zürich ETH – Uni ZH location. Additional regional offices in St. Gallen and Zürich give the firm a three-canton operating footprint across Thurgau, St. Gallen, and Zürich.

The core technical offering spans four divisions — Heizung/Kälte (heating and cooling), Lüftung/Klima (ventilation and air conditioning), Sanitär (sanitary), and Erneuerbare Energien/Service (renewable energy and service) — augmented by 24/7 emergency response, scheduled preventive maintenance, and energy consulting. Service delivery is field-based through project managers, service leaders, and technicians (e.g., Standortleiter Mario Grimm in Zürich, Bereichsleiter Roger Glaus in St. Gallen). The firm operates Suissetec-hosted online configurators for indicative heating and sanitary planning and holds ISO 9001:2015 (CH-QM-2020-1012-SAAG) and ISO 14001:2015 (CH-UM-2020-1012-StAG) certifications. A dedicated in-house apprenticeship workshop established in 2010, staffed by a full-time Leiter Berufsbildung (Gerhard Weinhappl) and equipped with 9 workstations and 5 welding boxes, trains 20-25 apprentices annually across 7 building-technology trades.

The business model combines one-time project installation revenue (heating/cooling/sanitary/renewable systems, individually quoted per project) with recurring maintenance and service-contract revenue from scheduled preventive maintenance, 24/7 emergency call-outs, and energy efficiency optimization. GTM is sales-led and relationship-driven: customers reach Steger AG via phone hotline, website contact form, or on-site consultation, with no third-party channel partners. Final pricing is quote-based and project-specific; multi-year maintenance contracts provide recurring revenue. Marketing is largely organic (website, Google Maps, Facebook, LinkedIn, Instagram). Operating practices include a 4-day work week (Monday–Thursday) and direct ownership of the talent pipeline through in-house vocational training, positioning the firm as a relationship-driven regional specialist rather than a scale player.
