About our AHU cleaning in Domewood
We clean air handling units for buildings in Domewood and across West Sussex, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers filter sections, drain trays and dampers and louvres, and people most often call us about dirty filters cutting the airflow and plant that has been serviced but not cleaned.
Work in a small place like Domewood starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
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.

Why deal with it now?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Planning a trip to Domewood ahead is easier for everyone than a rushed one.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.

What AHU cleaning cannot fix
We will not sell you work that doesn’t address the problem, so here are the limits:
- Problems with the unit’s controls or sensors
- Dirty ducts beyond the unit itself
- A system that’s undersized for the building
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we will say what we think before booking.

Domewood buildings and their air
There are about 7 hospitals, care homes and childcare premises on the FSA’s food hygiene register within about 1.5 miles of central Domewood. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 25 miles out from central London, Domewood is part of the South East area we work across. The visit is fixed around your opening hours, not ours. Domewood’s nearest hospital, Queen Victoria Hospital, is about 3.6 miles east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Queen Victoria Hospital, about 3.6 miles east, is the nearest hospital to Domewood, and healthcare sites of every size need their supply air kept clean.

When to call us in Domewood
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Most sites get in touch when they notice one of these:
- Drain trays holding standing water
- Filters that are clogged or overdue
- Plant that needs cleaning after a refit
- Plant that has been serviced but not cleaned
For schools like Imberhorne School, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before you book
- If they look at the system before pricing
- Whether they’re fully insured
- Whether inaccessible sections are listed on the report
- If the quote is a fixed price or an estimate
Fixed quotes for AHU cleaning in Domewood
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Where the site is and how we reach it
- When the work can happen, such as evenings, overnight or weekends
- Site rules, permits and inductions
- What state the system is in
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.
What we need to know
When you contact us, these details help:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Detail shots of panels, filters and grilles
- Photos showing the whole system and its surroundings
- The postcode and the type of business
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, phone us on 0345 646 2711 or send us an email.
Common questions in Domewood
Is Domewood within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Do you cover Domewood for AHU cleaning?
Yes. Our area runs across London and the South East, Domewood included. A fixed quote typically follows within one working day of the survey details.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Can you clean without disrupting the building?
Yes. The clean is planned around when the unit can be switched off. Healthcare and care settings are planned with staff.
Does the AHU have to be shut down for cleaning?
Yes, for the time we’re working on it. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
Part by part
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with pictures so repairs can be planned.
Internal casing and panels
We open each section through its doors and close them securely when we are done, and check every one is shut.
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Report water on the plant room floor
- Keep filter changes on time and recorded
- Keep the certificate and photo report with the plant records
- Book the next check in line with the report
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
The process
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. If the van will struggle with a lane or gateway near Domewood, let us know and we will plan around it.
- We agree a shutdown window that suits the building.
- 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 pictures are taken and the certificate issued.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Clear loose items from the work area
- Find the previous report, if there is one

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
