TESA HVAC was formed in 1974 by Mr. Bill Hathaway, who was a senior manager of a major British controls company. Initially T.E.S.A. provided site surveys and the preparation of quotations, based on control panel construction or schemes to the Heating and Ventilation market. 
The service soon grew to include the commissioning of completed schemes and was then extended to cover annual inspection and servicing of a wide range of control systems, due to the dedication we were seen to provide for our clients.
Our expansion continued by both the provision and specialised electrical installation of the control system. We are able to supply the complete environmental control package from design through procurement and installation - to final commissioning and beyond.
TESA prides itself on its adaptability, enabling it to meet the precise needs of clients and to design & build special purpose environmental control systems to suit any specification. It is this flexibility, combined with experience that gives TESA the ability to react promptly and enthusiastically to new ideas.
TESA can guarantee that if any control panel requires servicing or parts there will be the minimum of delay to your business. This is further aided by remote diagnostics keeping service costs to a minimum and ensuring you are fully operational.
TESA faces the future with the same priorities that distinguish its past:
