GSM Limited was formed over 30 years ago to provide a mechanical, design and installation service second to none. Our expertise covers all aspects of air movement design, including heating, ventilation, air-conditioning, dust and fume extraction to wood waste extraction systems.

Our client base is broad, working for companies in the retail, commercial and industrial fields. When appropriate we also undertake work directed to us from architects, consultants or developers as the need arises.

Diversity is our trademark, we are able to handle the manufacture and installation of heating, ventilation and air-conditioning systems ranging from a fully ducted system with a packaged air-conditioning unit, to a single ceiling cassette split system suitable for a single office. All systems are fully commissioned by our in house commissioning team.
