Air handling units (AHU) in Bristol
AHU replacement, EC fan upgrades, controls and planned servicing, across Bristol.
- From £10,350 + 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.
Bristol 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.

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.
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.
