Abacus AC Solutions is a family-run team of commercial air conditioning specialists — built on three decades of clean installs, honest advice and engineers London businesses trust.
Founded in 1989 and based in Ware, Hertfordshire, Abacus AC Solutions has grown from a two-man operation into one of London's most trusted commercial air conditioning contractors — without ever losing the personal, no-nonsense approach we started with.
We're not a national call centre. When you ring Abacus you speak to a real engineer, and the same faces that survey your premises are the ones who install, commission and look after your system for years afterwards. It's why most of our work still comes from referrals and repeat clients.
From a single van to a full commercial contractor — the milestones that shaped Abacus.
Started as a small refrigeration and air conditioning outfit serving local Hertfordshire businesses.
Growing demand from offices and restaurants takes our engineers across Greater London.
We invest in full certification and accreditation, becoming a trusted name for compliant commercial installs.
From single splits to building-wide VRF networks, our portfolio spans every commercial sector in the capital.
A full-service team delivering installation, maintenance and rapid repair — with the same values we began with.
