ambientAIR is part of The Excool Group, a Worcestershire based group specialising in advanced HVAC technologies across multiple sectors. The group dates back to 1984 and brings together specialist companies with over 40 years of experience in innovative heating, cooling and ventilation solutions.
Established in 2004, ambientAIR specialises in the design and installation of heating, air conditioning and ventilation systems, with a reputation built on practical, reliable solutions tailored to each customer.

Today those strengths sit under one roof, offering a comprehensive HVAC service from initial design through to installation, refurbishment and ongoing optimisation.
At the heart of the business are its people. The team works hard, supports one another and is encouraged to enjoy what they do. There are no shortcuts to hard work, and that commitment shows in the quality of every project delivered.
