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.
Our team is based in Great Barr, Birmingham, and we work throughout Lanarkshire, from Cumbernauld, Coatbridge, Airdrie, Motherwell and Rutherglen. The survey is free for new installations on the UK mainland, and the quote that follows is fixed and in writing.
