AHU cleaning for kitchens and businesses in Asheridge
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. The work covers dampers and louvres, supply and extract fans and internal panels, and common reasons people get in touch are plant that has been serviced but not cleaned and units needing a clean before a new tenant or handover.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

What happens on the day
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. In a small place like Asheridge, the journey is planned ahead and the visit arranged around the site’s hours.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Agree a time when the area can be out of use
- Let us know about permits to work or site inductions
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
Advice
How we price AHU cleaning
We don’t publish a price list, because sites vary so much. What we look at:
- The number of sites or systems
- The condition we find in the survey
- Whether we need access equipment or extra panels
- Parking and loading at the site
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
Helping us quote
You don’t need the technical terms. It helps if you can send:
- Your last certificate, test record or report
- The site address and the type of premises
- Your opening hours and when the area is out of use
- Anything you’ve noticed, such as smells, noise, drips or poor airflow

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Why act early in Asheridge
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. If the system at a site near Asheridge fails, there may be nowhere nearby to move to.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before work begins.

What we are called out for in Asheridge
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Clients usually contact us after spotting something like this:
- Plant that has been serviced but not cleaned
- Plant that needs cleaning after a refit
- Air handling units with blocked filters
- Blocked condensate drains and slimy trays
Healthcare buildings such as Chiltern Hospital, about 3.7 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Asheridge, yours matters too.
Before booking anyone
- Whether inaccessible sections are listed on the report
- Whether the quote shows VAT
- Whether a written report and pictures are included
- Whether the work can be done while the site is closed
What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:
- Mechanical faults with motors, belts or bearings
- Ductwork downstream of the unit, which is a separate clean
- Leaking heating or cooling coils
If you are not sure, just call us on 0345 646 2711 or use the quote form and we’ll give you a straight answer.
Where we work
- Dampers and louvres
- Supply and extract fans
