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 Ayrshire 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 Kilmarnock, Ayr, Irvine, Kilwinning and Troon.

How we do it
Many AHUs in older offices, schools and retail units run on belt-driven fans, clogged filters and controls nobody understands. Replacing the fan section with EC fans, or the whole unit with a modern heat recovery AHU, can cut running costs and noise while restoring airflow. New units must meet current ecodesign rules for fan efficiency and heat recovery.
