About our AHU cleaning in Woolmer Hill
Our AHU cleans for sites in Woolmer Hill cover the parts that collect dirt: 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 drain trays, dampers and louvres and supply and extract fans, and people most often call us about coils clogged with dust and debris and blocked condensate drains and slimy trays.
Somewhere as small as Woolmer Hill, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Duct Doctor has been trading since 2009, and we are 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.

Questions from Woolmer Hill
Can ventilation in schools around Woolmer Hill be cleaned out of term?
Yes, holiday work suits schools best. With about 7 schools and colleges on the FSA’s register within roughly a mile and a half of Woolmer Hill, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Do you work at weekends in Woolmer Hill?
Yes. We work evenings, overnight and at weekends. It means the site in Woolmer Hill keeps running as normal. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we’ll quote them together.
Will the ventilation be off while you clean?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
How long does it take to clean an air handling unit?
Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, and you can give us a ring on 0345 646 2711 or email us to plan it.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Do you work in Woolmer Hill?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Woolmer Hill included.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot 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 need training, the right equipment and safe access. That is our job.
How the visit works
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Rural roads and tight entrances are worth telling us about before a visit to Woolmer Hill.
- 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.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Mention any parking or loading restrictions
- Make sure someone can let us in and lock up afterwards
- Make sure equipment near the work can be switched off and left to cool

Why it’s worth doing now in Woolmer Hill
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Equipment tucked in a roof space or outbuilding near Woolmer Hill rarely gets looked at unless someone books it.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Why Woolmer Hill businesses choose us
- Every job surveyed first
- Fully insured
- Evenings, overnight and weekends, plus 24/7 emergency callout
- Accredited under CHAS and SafeContractor, with ISO 9001
When to call us in Woolmer Hill
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Signs it’s time to call us include:
- Dust built up on fan impellers
- Air handling units due a clean after building work
- Air handling units never cleaned inside
- Leaves and litter drawn into the unit
If you run a surgery, dental practice or care home near Woolmer Hill, clean ventilation matters as much to you as to a hospital like Haslemere and District Hospital (about 2 miles north-east).

- What paperwork you get at the end

Looking after it afterwards
So the system stays in good health:
- Flag stale or damp smells in the supply air
- Plan the next inspection before the last report gets filed away
- Keep the area around the fresh air intake clear
- Keep filter changes on time and recorded
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
What affects the cost of AHU cleaning
The survey tells us what the work involves. We look at:
- The size of the system
- Any permits to work or inductions
- The condition of the system
- Travel, parking and unloading
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
Helping us quote

- The site address and the type of premises
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
- How we’d reach plant on a roof or in a plant room

Managing agents and facilities teams in Woolmer Hill
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
