With partnerships with manufacturers like Toshiba and Daikin, we deliver tailored solutions that prioritise energy efficiency and client-specific requirements.
AHU Refurbishment
Our air handling unit (AHU) refurbishment services extend equipment lifespan while improving energy efficiency. We replace outdated components like fans and coils, reduce casing leakage, and integrate modern controls. This cost-effective alternative to full replacement minimises downtime and aligns with sustainability goals, ensuring optimal performance for commercial buildings.

Our process includes site surveys, craneage, and disposal of old units, alongside mechanical and electrical integration. This reduces operating costs and ensures compliance with F Gas Regulations, tailored to existing system requirements.
Boiler Installation
We design and install commercial boiler systems, from single units to multi-boiler rigs with building management integration. Our solutions focus on energy efficiency, reducing bills through optimised controls and high-efficiency appliances. Projects include space heating for large facilities using radiant tube heaters and warm air units, ensuring reliable year-round performance.
