AHU cleaning in Bradfield, done properly
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers dampers and louvres, filter sections and supply and extract fans, and the jobs we see most are stale or musty smells from the ventilation and leaves and litter drawn into the unit.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

The process
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Bradfield, the date and timings are agreed with you well before the day.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Arrange a key holder or contact on site
- Find the previous report, if there is one
- Mention any parking or loading restrictions
How to get a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.
Advice
What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
What affects the quote in Bradfield
We do not publish a price list, because sites vary so much. What we look at:
- Whether it’s a one-off visit or part of a schedule
- Where the site is and how we reach it
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
We can often survey from pictures. Try to include:
- The roof, plant room or outside wall the system runs to
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Systems in rural buildings are often out of sight and out of mind.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.

Common problems we fix in Bradfield
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Most sites get in touch when they notice one of these:
- Blocked condensate drains and slimy trays
- Intake sections clogged with outdoor debris
- Stale or musty smells from the ventilation
- Plant that needs cleaning after a refit
School buildings such as Bradfield Primary School are usually done in the holidays, so classrooms are not disturbed.
Questions to ask before you book
- Whether VAT is included
- When they can work, and whether that is outside your opening hours
- What happens if part of the system can’t be accessed
- What insurance they carry
Bradfield questions
Do you cover smaller places like Bradfield?
Yes, smaller places are covered as well as towns. A survey first, from photos or a visit, means we arrive with the right kit.
Do you clean school ventilation in Bradfield in the holidays?
Yes. The holidays are the usual time for school work. Around Bradfield, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. You can call 0345 646 2711, or email photos with the dates the site is empty.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
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.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and the report recommends a next date.
What does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we will usually reply within one working day.
Honest limits
We’ll always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Leaking heating or cooling coils
- Ductwork downstream of the unit, which is a separate clean
- Ventilation that was badly designed in the first place
Not sure which it is? You can ring 0345 646 2711, or send details by email and we will tell you honestly.
