AHU cleaning in Bradfield Heath
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers dampers and louvres, drain trays and internal panels, and people most often call us about stale or musty smells from the ventilation and units needing a clean before a new tenant or handover.
Work in a small place like Bradfield Heath starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Good records are part of the job. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Bradfield Heath questions
Can the work in Bradfield Heath be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. That way a site in Bradfield Heath doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Can you clean school ventilation in Bradfield Heath during the holidays?
Yes. The holidays are the usual time for school work. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Bradfield Heath, it pays to plan holiday dates ahead. Send us your term dates when you phone us on 0345 646 2711, or email photos, and we’ll fit the work in.
Can you fix a faulty AHU?
We clean the unit and flag faults rather than repair them, with the details in the report.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
What happens if you can’t reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.

What we do, step by step
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes from a few hours for a compact unit to a day or more for a large one. The timing of a visit to Bradfield Heath is set by you, and the travel is our side of the planning.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Clear loose items from the work area
- Name a contact who can let us in at the agreed time
- Have your last certificate or report to hand

Do you need AHU cleaning in Bradfield Heath?
Whatever surrounds a building in Bradfield Heath, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Clients usually contact us when they notice one of these:
- Dust-coated heating and cooling coils
- Plant that has been serviced but not cleaned
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue
School buildings such as Bradfield Primary School are normally done in the holidays, so classrooms are not disturbed.
What your quote should include
- Whether inaccessible sections are listed on the report
- Exactly which parts of the system are covered
- When they can work, and whether that is outside your opening hours
- Proof of insurance
What AHU cleaning can’t fix
Before booking, it helps to know what’s not included:
- Ductwork downstream of the unit, which is a separate clean
- Problems with the unit’s controls or sensors
- Leaking heating or cooling coils
If in doubt, give us a ring on 0345 646 2711, or send details by email and we’ll say what we think before booking.

Fixed quotes for AHU cleaning in Bradfield Heath
Before we fix a price, we need to know a few things. We check:
- The number of sites or systems
- How easy every part is to reach
- When the work can happen, such as evenings, overnight or weekends
- The size of the system
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.
Helping us quote
You do not need the technical terms. It helps if you can send:
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- A few general shots of the system
For a fixed quote, call us on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You will typically have a quote within one working day.
Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Don’t ignore odours coming through the grilles
- Change filters on schedule and log each change
- Do not store bins or materials near the intake
- Plan the next inspection before the last report gets filed away
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
Why it’s worth doing now in Bradfield Heath
Standing water in a drain tray doesn’t clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. Planning a trip to Bradfield Heath ahead is easier for everyone than a rushed one.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.

How the job changes from site to site
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
