About us

Since 1992 Cooltech Environmental Engineering has built an enviable reputation for design expertise in the installation of mechanical and electrical servies, specialising in clinical air conditioning and ventilation systems. The company expanded and then formed a separate service and maintenance division to offer ongoing support services. Cooltech is now recognised throughout the industry as a leading supplier and partner in its field.

Whilst retaining the capability of capital projects and installations, we are now primarily a mechanical, electrical, and HVAC maintenance provider to the facilities market.

Cooltech, remains a privately owned company which is owned and managed by engineers, Peter Sawyer (chairman) who specialises in refrigeration and Tony Williams (managing director) who specialises in combustion/heating and ventilation.

We recognise that our performance as a company is equal to the knowledge of our staff and their continued commitment to our goal and that of our clients.
