An air handling unit (AHU) is the central plant that filters, moves and often heats, cools or recovers heat from the air for a building's ventilation system. We replace ageing units, upgrade fans and controls, and service AHUs so they keep delivering their design airflows.
Across Gloucestershire the job is priced the same way wherever you are: what is fitted, how long it takes and how far we travel. Towns we cover include Cheltenham, Stroud, Kingswood, Mangotsfield and Yate.

Planned servicing
Filters, belts, coils, drains and controls on a schedule.
Like-for-like replacement
New unit in the same position, connected to existing ductwork.
EC fan retrofit
