The contractor, which has offices in Manchester, Cannock and Maidstone, has attained the coveted status of Mitsubishi Electric Diamond Quality Partner.

Deane Flint, sales and marketing director for Mitsubishi Electric, explained: “The Diamond Quality Partner status recognises that Coolair has achieved exceptional levels of training, skills and customer satisfaction, as well as acknowledging its expertise in the design and installation of HVAC systems using Mitsubishi Electric’s range of products.”  

Coolair is one of the first companies to receive the UK’s highest partnering classification for excellence in installing the Mitsubishi Electric’s heating and cooling products.

Mark Garstang, Coolair regional director, commented: “Having already built up a successful working relationship with Mitsubishi Electric as a Business Solutions Partner, we are delighted to have been invited to join a new Premier League of contractors that meet the world-renowned company’s high quality standards.”

Coolair received the accreditation after its installations in southern England were audited by an independent specialist, and the company will continue to be audited to maintain its prestigious new status.

Mr Garstang added: “As well as having our installations checked and validated, customers will benefit from our access to the full Mitsubishi Electric product range, as well as its advanced tools to monitor and optimise system design for lifelong performance.”
