Air handling units (AHU) in Tayside
AHU replacement, EC fan upgrades, controls and planned servicing, across Tayside.
- From £9,550 + VAT per unit
- Free survey
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.
Tayside has every kind of building, from old terraces to new estates and business parks, and every job is designed around the building in front of us, not a standard kit.

What the work involves
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. Replacements often involve crane lifts, roof work and out-of-hours changeovers.
Like-for-like replacement
New unit in the same position, connected to existing ductwork.
EC fan retrofit

Controls upgrade
