AHU replacement, EC fan upgrades, controls and planned servicing, across the West Midlands.
- From £9,950 + 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.
Our team is based in Great Barr, Birmingham, and we work throughout the West Midlands, from Dudley, Walsall, Solihull, Sutton Coldfield and West Bromwich. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it
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. We plan the lift, temporary arrangements and isolations with you so the building can keep working.
EC fan retrofit
Belt-driven fans replaced with direct-drive EC fans.
Controls upgrade
New controls, sensors and BMS integration.
Planned servicing
Filters, belts, coils, drains and controls on a schedule.

Questions about air handling units (AHU) in the West Midlands
Is the survey free in the West Midlands?
For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.
Is it worth replacing belt-driven fans with EC fans?
Often yes. EC fans are usually more efficient, quieter and need no belt changes, and the retrofit can cost much less than a new unit.
Can you work out of hours?
Yes. Changeovers and crane lifts are often done at weekends or evenings to avoid disruption.
Which rules apply to ventilation in the West Midlands?
In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
Which towns in the West Midlands do you cover?
All of the West Midlands, including Dudley, Walsall, Solihull, Sutton Coldfield and West Bromwich. If your town is not listed, send the postcode and we will confirm.
