1. The Beginning of iACS
Founded in 2011 as i-A.C. Systems, iACS began with a simple objective: to provide high-quality control solutions specifically tailored to Air Handling Units.
From a small office in South East London, the company focused on delivering reliable control panels, software, and commissioning support for AHU manufacturers across the UK.
By concentrating on a specialist area of HVAC controls, iACS quickly established a reputation for technical expertise, responsiveness, and innovation.
Over the years, the company has grown organically, expanding its engineering, software development, manufacturing, and project delivery capabilities while maintaining its commitment to customer support.
2. Becoming an AHU Controls Specialist
Air Handling Units remain at the heart of modern HVAC systems.
As AHU technology evolved, so did the complexity of the control systems required to manage:
