Fan upgrades and better controls can cut energy use significantly on older units.

Working hours

Most Horley businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.

Replacement logistics

Large AHU replacements need craneage, road closures and careful programming.

Shared buildings

In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.

Who we work with in Horley

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
