In 1974, T.E.S.A. was founded with the aim of providing site surveys and preparing quotations for control panel construction and schemes in the Heating and Ventilation market. Our services quickly expanded to include the commissioning of completed systems, followed by annual inspections and servicing for various control systems. This growth was driven by our commitment to exceptional service and building lasting relationships with our clients.
As our reputation for quality and reliability grew, we extended our offerings to include the supply and specialised electrical installation of complete control systems. Today, we provide a comprehensive environmental control solution, from initial design and procurement to installation, final commissioning, and ongoing support.
Now, as the company moves into its third generation of the founding family, T.E.S.A. continues to build on over 50 years of experience.
