What affects the cost of AHU cleaning
We don’t publish a price list, because sites vary so much. The quote depends on:
- Where the site is and how we reach it
- Site requirements such as sign-in and permits
- Working hours and out-of-hours timing
- Whether several sites go on one quote
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.
What we need to know
To help us quote quickly, send us:
- Any symptoms, from odd noises to smells or leaks
- A few general shots of the system
- The times we could work without disrupting the site
- The postcode and the type of business
Getting a quote does not take long. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
How we handle AHU cleaning in West Kingston
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. If you have condensate trays that won’t empty and debris and leaves in the fresh air intake, we can put it right, from filter sections, drain trays and supply and extract fans onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Duct Doctor has been trading since 2009, as 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 it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, which takes anything from half a day for one small unit to several shifts for a plant room full of them. A quick note on how to find the site and where to park makes a visit to West Kingston run smoothly.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Tell us where we can park and unload
- Let us know about permits to work or site inductions
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
For a fixed quote, ring 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You will normally have a quote within one working day.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:
- The supply and extract ducts, quoted separately
- Coils that are corroded or leaking and need replacing
- Mechanical faults with motors, belts or bearings
If in doubt, ring 0345 646 2711 or email us and we’ll say what we think.
Parts of the system we cover
- Drain trays
- Filter sections
- Dampers and louvres
- Internal panels
- Supply and extract fans
- Heating and cooling coils
Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Plan the next inspection before the last report gets filed away
- Make sure the unit’s access doors open easily
- Do not store bins or materials near the intake
- Keep filter changes on time and recorded
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
What AHU cleaning looks like in West Kingston
Food Standards Agency data includes about 11 schools, colleges and universities and about 14 caring premises (care homes, nurseries and hospitals) within about 1.5 miles of central West Kingston. Busy, occupied buildings like these are where clean supply air matters most. The nearest hospital to West Kingston is Zachary Merton Hospital, about 1.5 miles west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. West Kingston is about 51 miles from central London, well within the area we cover across London and the South East. Visits are booked around your hours, evenings and weekends included.
Classrooms and halls at schools such as East Preston Infant School are easiest to work in when pupils are away. Healthcare buildings such as Zachary Merton Hospital, about 1.5 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near West Kingston, yours matters too.

What happens if it’s left?
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Planning a trip to West Kingston ahead is easier for everyone than a rushed one.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711, or email photos for straight advice and a fixed quote.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
West Kingston questions
Can ventilation in schools around West Kingston be cleaned out of term?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 11 schools and colleges with food registrations within roughly a mile and a half of West Kingston. Just phone us on 0345 646 2711, or email photos with your term dates and we will plan around them.
Is West Kingston within the area you cover?
Yes, West Kingston is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you have insurance?
Yes. We are fully insured, and we can share the details when you need them.
How much does AHU cleaning cost in West Kingston?
We don’t publish prices, because the cost 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 work begins.
Can you clean without disrupting the building?
Yes, if daytime working is not practical. We plan the shutdown window with you.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
