AHU cleaning in Woodside
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so you can see the unit’s condition for yourself. If you have dirty coils holding back the airflow and intake sections clogged with outdoor debris, we can help, from heating and cooling coils, filter sections and drain trays onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What AHU cleaning cannot fix
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It does not solve:
- A system that is undersized for the building
- Faulty motors, drives or bearings
- Building management system faults
If in doubt, give us a ring on 0345 646 2711, or send details by email and we will say what we think before you book.
Parts of the system we cover
- Filter sections
- Drain trays
- Dampers and louvres
- Heating and cooling coils
- Supply and extract fans
- Internal panels
How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes a single shift for a typical unit, longer for large or heavily soiled ones. Rural roads and tight entrances are worth telling us about before a visit to Woodside.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Before we arrive
- Dig out any earlier paperwork for the system
- Name a contact who can let us in at the agreed time
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
How to get a quote
Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Landlords, agents and facilities managers
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
What affects the cost of AHU cleaning
We do not publish a price list, because no two systems are the same. What we look at:
- Whether several sites go on one quote
- Working hours and out-of-hours timing
- Whether it’s a one-off visit or part of a schedule
- Where the site is and how we reach it
What you pay depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.
What to send for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- A few general shots of the system
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
Aftercare tips
To keep the system working properly between visits:
- Don’t store bins or materials near the intake
- Keep inspection doors on the unit in good order
- Watch for drips or damp patches near the plant
- File each AHU report in the maintenance log
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
Your questions about AHU cleaning in Woodside
Do you work at weekends in Woodside?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Do you cover smaller places like Woodside?
Yes, we work in villages as well as towns, and Woodside is covered. The journey is planned ahead, so a few details about the route help.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
Can you look after several sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
What about areas you cannot get to?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do you need to switch the unit off?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What the work involves, part by part
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.

What AHU cleaning looks like in Woodside
The FSA’s food hygiene register lists about 4 schools, colleges and universities with registered kitchens or food service within roughly a mile and a half of the centre of Woodside. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Heatherwood Hospital is the nearest hospital, about 1.7 miles south-west of Woodside. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. At about 25 miles from central London, Woodside sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site.

What we are called out for in Woodside
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Most sites get in touch after spotting something like this:
- Stale or musty smells from the ventilation
- Leaves and litter drawn into the unit
- Coils clogged with dust and debris
- Air handling units due a clean after building work
Wherever a school like Cranbourne Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
