Air handling units (AHU) in Lincolnshire

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.

Lincolnshire 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.

Questions about air handling units (AHU) in Lincolnshire

Is the survey free in Lincolnshire?

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.

How often should an AHU be serviced?

Most AHUs need servicing at least twice a year, with filters changed more often in dirty environments. SFG20 schedules are commonly used to set frequencies.

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.

Which rules apply to ventilation in Lincolnshire?

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.
