How we price AHU cleaning
You will get a fixed price before work begins. It’s based on:
- Site requirements such as sign-in and permits
- A single visit or a regular plan
- How big the system is
- How easy every part is to reach
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
What we need to know
You do not need the technical terms. Just send:
- Wide pictures of the system and the area around it
- Any access panels or hatches you can see
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
If you need AHU cleaning in Denton, ring 0345 646 2711 or send us an email. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. We normally send a fixed quote within one working day.
AHU cleaning in Denton, done properly
Where a building in Denton has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you’re dealing with units that have only ever had filter changes and debris and leaves in the fresh air intake, we can put it right, from dampers and louvres, supply and extract fans and internal panels onwards.
In a smaller place like Denton, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

How the job changes from site to site
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
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.
Staff cleaning versus specialist work
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.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
Your questions about AHU cleaning in Denton
Do you work overnight in Denton?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.
Is AHU cleaning available in Denton?
Yes, Denton is covered. You can phone us on 0345 646 2711 or drop us a line and let us know what needs doing.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
How long does an AHU clean take?
Typically the clean takes one overnight shift for many single units, with bigger plant phased. The shutdown is planned to fit, including evenings or weekends.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
What happens if you cannot reach some of it?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
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.
Ventilation in Denton buildings
For Denton, the closest hospital is Chailey Heritage Marine Hospital, roughly 1.5 miles south.

What else we do in Denton
When to call us in Denton
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Dust built up on fan impellers
- Drain trays holding standing water
- Leaves and litter drawn into the unit
- Odours coming through the supply air
Chailey Heritage Marine Hospital, about 1.5 miles south, is the nearest hospital to Denton, and healthcare sites of every size need their supply air kept clean.
Comparing quotes
- What insurance they carry
- What paperwork you get at the end
- Whether the quote is based on a survey or pictures
- Whether the work can be done while the site is closed
The process
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and the area is cleaned down before we leave. Evenings, weekends or a closed day all work for a site in a place like Denton.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Before we arrive
- Clear the space around the work
- Mention any sign-in, permit or induction we need
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.
Advice
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- File each AHU report in the maintenance log
- Keep filter changes on time and recorded
- Book the next check in line with the report
- Keep inspection doors on the unit in good order
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
