- From £10,350 + VAT per unit

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 Cornwall 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 Camborne, Newquay, Penzance, Bodmin and Redruth.

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
Belt-driven fans replaced with direct-drive EC fans.
Controls upgrade
New controls, sensors and BMS integration.
