What Oscar Hanson Plumbing does

Oscar Hanson VVS is a Halmstad-based, privately held HVAC/VVS contractor founded in 1916, operating under the legal entity AB Oscar Hanson VVS. The company provides heating, ventilation, sanitation, and cooling (VVS) services to both private homeowners and enterprise/industrial customers across the Halland region of Sweden, employing approximately 100 people across installation (Entreprenad), service, and energy optimization departments.

The company's core offering is organized into four service lines: Entreprenad (full-responsibility installation contracting for traditional VVS work through complex industrial process installations, including function contracts that guarantee performance post-commissioning); Service (maintenance and repair with ~20 service technicians and fully equipped vehicles covering water/sewage, heating, ventilation, heat pumps, and pool systems); Energioptimering (energy optimization consulting with proprietary parallel calculations for total annual cost of heating, cooling, and air handling systems); and Debiteringspriser/ROT (transparently priced service work, with 30% Swedish ROT tax deduction applied for qualifying residential customers). Its technical capabilities rest on in-house engineers, project designers, and certified technicians, supported by ISO 9001:2015, ISO 14001:2015, IN Q, Säker Vatten, ISO 3834-2 welding, and gas pressure testing certifications.

Revenue is generated on a professional services basis through direct field sales, project contracting, and transaction-based hourly service work (995-1,015 SEK/hour including VAT). The go-to-market combines regional direct sales, a self-serve quote/inquiry portal, dedicated phone/email contact channels by department, and community-driven brand building through extensive local sports sponsorships and youth employment programs. The company is family-controlled across three generations of the Hanson family, has no external investors or parent company, and has executed six historical acquisitions of smaller local VVS businesses (1994-2021) to consolidate regional market position.
