TEWA

What TEWA does

TEWA GmbH is a privately held German HVAC services company headquartered in Gronau, North Rhine-Westphalia, operating across western and northern Germany through a multi-entity structure that includes TEWA Nord GmbH (Oldenburg), TEWA Steuerungs- und Regelungstechnik GmbH (Gronau), and a branch office in Sprockhövel (Niederlassung Wuppertal). Founded circa 1999 with more than 30 years of referenced operational experience, the company is managed by Gerhard Meyer and Maik Meyer and holds ISO 9001 certification via DEKRA (since July 17, 2001), prequalification status (PQ 011.110023), and Betriebszertifizierung under the German Chemicals Climate Protection Regulation.

TEWA's core offering spans the full HVAC lifecycle: planning, installation, and maintenance of ventilation systems, air conditioning, refrigeration and cooling, building automation, and control cabinet construction (Schaltschrankbau). Its technology stack relies on mainstream control platforms (SAIA, Siemens, ELESTA) integrated into customized switchgear and Mess-, Steuer- und Regeltechnik (measurement, control and regulation technology), with remote monitoring, fault elimination via data transmission, and energy optimization as value-add features. The company also provides regulatory compliance services including VDI 6022 hygiene inspections and F-Gas regulation leak testing.

TEWA generates revenue through professional services and project work delivered via direct field service: 25 fully equipped service vehicles deploy to customer sites for installation, maintenance, emergency service, and technical reporting. Pricing is quote-based and undisclosed. The customer base spans commercial buildings, industrial facilities (printing, chemical, chip, data centers, telecom centers, laboratories), healthcare facilities, and transportation infrastructure. The company markets primarily through its website (tewa.de) and a careers page, with no resellers, distributors, or marketplace channels identified.

Direct peers

• Apleona (formerly WISAG): One of Germany's largest facility-services and HVAC service providers, offering HVAC installation, maintenance, and building automation across multiple industries. Direct competitor for enterprise HVAC service contracts, but at significantly larger scale.
• Gegenbauer: German facility-management and technical building services provider with HVAC and refrigeration capabilities serving commercial and industrial customers. Comparable mid-to-large regional competitor for HVAC service contracts.
• Piepenbrock: German family-owned facility-services group with HVAC, refrigeration, and building-maintenance offerings. Closely comparable to TEWA in being family-controlled and Germany-focused, but operating at larger scale.

Broad incumbents

• ENGIE Deutschland: Major German energy and facility-services group with deep HVAC, refrigeration, and building-automation capabilities. Competes for the same commercial and industrial climate-control contracts as TEWA but as part of a broader multi-service portfolio.
• Dussmann Group (KDL): German facility-services conglomerate providing technical building services including HVAC, refrigeration, and building automation. Overlaps with TEWA's customer base of commercial buildings, hospitals, and industrial sites.
• STRABAG Property and Facility Services: Facility-services arm of STRABAG providing technical building management including HVAC and refrigeration. Competes for enterprise HVAC contracts as part of an integrated property services offering.
• Stiebel Eltron: German manufacturer of heating, ventilation, and heat-pump systems. Adjacent rather than direct overlap, as Stiebel Eltron supplies equipment while TEWA installs and services it; both target German commercial and residential HVAC markets.
• Viessmann: Major German manufacturer of heating, refrigeration, and climate systems. Comparable in that its products are installed and serviced by German HVAC contractors like TEWA, and Viessmann itself increasingly competes in the service space via Viessmann Climate Solutions.
• Vaillant Group: German-headquartered heating and HVAC systems manufacturer. Comparable through overlap of customers (commercial heating/HVAC) and through Vaillant's growing service-network and digital offerings targeting similar German enterprise accounts.

Regional players

• Sodexo (Technical Facility Services): Global facility-management group with a German technical facility-services division covering HVAC, refrigeration, and building maintenance. Competes in the same enterprise tender pool but with a much broader service portfolio.
