Lee Wiseman, Director.

After completing a 4-year electrician apprenticeship in 2001, Lee followed up with a 4-year refrigeration mechanic apprenticeship. By 2005, he was doubly qualified and involved in a wide variety of commercial air-conditioning jobs, doing everything from site measures to high-level electrical controls. In 2011, after 10 years with National Air, Lee decided to start his own business – Acertech. It was a new challenge, one that Lee was ready to take on – he had lots of new ideas, ways to improve servicing, be more cost-effect, innovative and ingenious. Lee began Acertech as a sole contractor (with a car and trailer) but word soon spread about his work ethic and problem solving ability, and he started employing people to keep up with demand. Servicing both the commercial and residential air-conditioning markets, Acertech went from strength the strength, doubling its turnover each year. In 2020, with 20 employees, Lee (alongside Josh and Dan) decided to restructure Acertech (and its residential counterpart, Air Conditions) and rebrand it as Acer Air – a streamlined business, better equipped and prepared for the greater challenges ahead.

“For me, the business has always been about improvement through innovation. We are relatively young people in a relatively new business, full of energy and ideas, willing to try new things, test out theories, come up with better ways of working… not only for our clients, but for ourselves. Our staff work 4-day weeks because we believe in work-life balance. We’re actually more productive because of it – everyone at Acer Air is motivated and keen to do their best for the company, which means doing their best for our clients.”
