AC Energi

What AC Energi does

AC A/S is a Danish technical installation company founded in 1998, headquartered in Vejle with a branch office in Jelling, employing approximately 70 staff across installation, service, and administration. The company operates through two operational divisions — AC EL (electrical) and AC Energi (plumbing/heating and energy solutions) — and delivers a full portfolio of building technical services including electrical installation, VVS (plumbing and heating), sheet metal and roofing work, security and fire alarm systems, communications and data networks, lighting, and intelligent building automation via KNX/IHC/Siedle platforms. Its energy offering spans heat pumps (air-water, air-air, and ground source/geothermal), solar PV, solar thermal, and ventilation systems.

The company is certified as a VE-godkendt (Renewable Energy) installer by the Danish Energy Agency (Energistyrelsen), a KSO-certified solar installer, and an authorized electrical and VVS installer. It serves three primary customer segments — private households, commercial businesses, and public institutions — across the Vejle, Jelling, and broader Triangle Area (Trekantsomr\u00e5det) of Denmark, with project work extending into Jutland and Funen. Notable customers include Vejle Kommune, Ove Larsen A/S, Tønnes & Ulstrup, Vinding Tømrer, and Arkitekt Huset.

AC generates revenue primarily through project-based installation services priced by quote, supplemented by recurring VVS service/maintenance contracts and a 24/7 emergency call-out service (Døgnvagt) with publicly disclosed premium pricing. Go-to-market is sales-led and direct, leveraging a website with detailed service pages, a Facebook presence, Koble network referrals, and named-owner outreach (multiple co-owners hold the Danish designation "Indehaver" and serve as direct customer contacts). The company is privately held, owner-operated, and a member of the Koble and Blue Install trade networks; no external investors, acquisitions, or parent-company structure are indicated in available sources.
