AHU cleaning for kitchens and businesses in Stonesfield
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. The work covers dampers and louvres, drain trays and internal panels, and people most often call us about filters that are clogged or overdue and odours coming through the supply air.
Work in a small place like Stonesfield starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
A written report with photos follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Different parts, different methods

Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.

Is Stonesfield in your area for AHU cleaning?

What about areas you cannot get to?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.

Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
Do you do ventilation duct cleaning too?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.

Between visits
Once we’ve finished, these simple steps help:
- Do not ignore odours coming through the grilles
- Make sure the unit’s access doors open easily
- Change filters on schedule and log each change
- Clear leaves and litter away from the intake
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Why deal with it now?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. If the system at a site near Stonesfield fails, there may be nowhere nearby to move to.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before any work starts.

For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
We also work for facilities teams across offices, schools and healthcare in Stonesfield and across Oxfordshire. Work can be phased by floor, building or site around the people who use them.
How we price AHU cleaning
There’s no set price list, because sites vary so much. What we look at:
- Whether it’s a one-off visit or part of a schedule
- The condition of the system
- When the work can happen, such as evenings, overnight or weekends
- The number of sites or systems
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’ll go through it with you.
Asking for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- The times we could work without disrupting the site
- Problems your staff have spotted
- Detail shots of panels, filters and grilles
- The roof, plant room or outside wall the system runs to
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, ring 0345 646 2711, or send details by email.
