Honest limits
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It will not put right:
- Leaking heating or cooling coils
- Building management system faults
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we’ll tell you honestly.
Where we work
- Filter sections
- Dampers and louvres
- Heating and cooling coils

AHU cleaning for kitchens and businesses in West Stoke
Our AHU cleans for sites in West Stoke cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers supply and extract fans, filter sections and internal panels, and the jobs we see most are dust built up on fan impellers and blocked condensate drains and slimy trays.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

West Stoke: your questions answered
Do you offer AHU cleaning in West Stoke?
Yes, we work in West Stoke and the places around it. Get in touch with the details and we’ll arrange a survey.
Can you work in West Stoke outside opening hours?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in West Stoke needn’t be disturbed. Just call 0345 646 2711 or send us an email with your opening times and we will plan around them.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
How often should an air handling unit be cleaned?
That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where necessary.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
What happens on the day
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, tidy up and hand over the paperwork. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. A quick note on how to find the site and where to park makes a visit to West Stoke run smoothly.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know when the site is closed or quiet
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Quotes are quick. Send a few details and pictures, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

What the work involves, part by part
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
How we price AHU cleaning
The survey tells us what the work involves. We look at:
- The number of sites or systems
- Travel, parking and unloading
- Working hours and out-of-hours timing
- Any permits to work or inductions
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before any work starts.
Helping us quote
Many jobs can be priced from photos and some basics. Useful things to send:
- The roof, plant room or outside wall the system runs to
- Problems your staff have spotted
- Where the site is and what kind of site it is
- The times we could work without disrupting the site
To help us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then call 0345 646 2711, or email photos.
Why it’s worth doing now in West Stoke
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. In a place like West Stoke, ductwork and fans are easy to forget until something goes wrong.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

What we’re called out for in West Stoke
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Keep an eye out for any of the following:
- Leaves and litter drawn into the unit
- Air handling units due a clean after building work
- Fan sections that haven’t been cleaned in years
- Plant that has been serviced but not cleaned
If you manage a school such as Bishop Luffa School, ventilation cleaning is best booked for the holidays.
