How we handle AHU cleaning in Hilden Park
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. The work covers filter sections, heating and cooling coils and supply and extract fans, and people most often call us about dirty fans and fan housings and odours coming through the supply air.
In a village or hamlet like Hilden Park, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
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 carry full insurance.

What AHU cleaning can’t fix
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- Dirty ducts beyond the unit itself
- A system that’s undersized for the building
- Building management system faults
If you are not sure, just give us a ring on 0345 646 2711 or email us and we’ll give you a straight answer before you book.
Parts of the system we cover
- Dampers and louvres
- Drain trays
- Internal panels
- Supply and extract fans
- Filter sections
- Heating and cooling coils
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Hilden Park questions
Do you work overnight in Hilden Park?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Just call us on 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
Can you clean school ventilation in Hilden Park during the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 18 schools, colleges and universities with registered kitchens within about a mile and a half of Hilden Park. Tell us your holiday dates and we will book the visit for when the site is empty.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What information do you need?
A short description and a few pictures plus the address and your hours. If we need more, we’ll ask.
Can you quote from pictures?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Are you fully insured?
Yes. We are fully insured, and the details are available on request.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.

Fixed quotes for AHU cleaning in Hilden Park
The survey tells us what the work involves. We look at:

What we are called out for in Hilden Park
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
It’s time to book a visit if you see:
- Odours coming through the supply air
- Debris and leaves in the fresh air intake
- Dirty filters cutting the airflow
- Units needing a clean before a new tenant or handover
School buildings such as Stocks Green Primary School are normally done in the holidays, so classrooms are not disturbed.
What your quote should include
- Whether the figure could change on the day
- How VAT is shown on the quote
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the work can be done while the site is closed
Why act early in Hilden Park
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. In a place like Hilden Park, ductwork and fans are easy to forget until something goes wrong.
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
Why us?
- Out-of-hours work and a 24/7 emergency line

What happens on the day
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes half a day to a full day per unit, with large plant planned over several shifts. If you can send photos, we can arrive in Hilden Park knowing what to expect.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Arrange a key holder or contact on site
- Mention any locked doors, roof access or ceiling voids
- Agree a time when the area can be out of use
Getting a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
Advice
Part by part
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with photos so you can decide on any repairs.
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
