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.
We carry out air handling units (AHU) across Bedfordshire, including Biggleswade, Flitwick, Luton, Bedford and Dunstable. Prices use East of England rates. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it
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.
Controls upgrade
New controls, sensors and BMS integration.
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.
