Air handling unit cleaning in Brookwood, Surrey
For AHU cleaning in Brookwood, one call is all it takes, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Plant that has been serviced but not cleaned
- Plant that needs cleaning after a refit
- Dirty fans and fan housings
Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Stick to the filter change plan
- Clear leaves and litter away from the intake
- Report stiff or damaged access doors
- Watch for drips or damp patches near the plant
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
About our AHU cleaning in Brookwood
We clean air handling units for buildings in Brookwood and across Surrey, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Typical jobs include air handling units due a clean after building work and drain trays holding standing water, across dampers and louvres, internal panels and heating and cooling coils.
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, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Brookwood buildings and their air
Going by the FSA’s register, there are about 7 care, childcare and hospital premises serving food within 1.5 miles or so of the middle of Brookwood. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Brookwood is about 27 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible. For Brookwood, the closest hospital is Brookwood Hospital, roughly 1.1 miles north-east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you run a surgery, dental practice or care home near Brookwood, clean ventilation matters as much to you as to a hospital like Brookwood Hospital (about 1.1 miles north-east). Workplaces around Brookwood station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. School buildings such as Brookwood Primary School are usually done in the holidays, so classrooms aren’t disturbed.

Fixed quotes for AHU cleaning in Brookwood

- How easy every part is to reach
- How many systems or sites are involved
- Travel, parking and unloading
- When the work can happen, such as evenings, overnight or weekends
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before work begins.

- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
- Your last certificate, test record or report
- A few general shots of the system

The process
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes one overnight shift for many single units, with bigger plant phased. In a small place like Brookwood, the journey is planned ahead and the visit arranged around the site’s hours.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Let us know about parking and loading
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know when the site is closed or quiet

For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
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.
What happens if it’s left?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. It’s worth booking a check, because nobody sees inside a duct day to day.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.
Why us?
- CHAS, SafeContractor and ISO 9001
- Fully insured
- Fixed quotes from a survey or pictures
- Trading since 2009
What the work involves, part by part
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.
Your questions about AHU cleaning in Brookwood
Can you work in Brookwood outside opening hours?
Yes, evening, overnight and weekend work is normal for us. That way a site in Brookwood does not have to lose a day’s trading. Just ring 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Do you cover smaller places like Brookwood?
Yes, we work in villages as well as towns, and Brookwood is covered. The journey is planned ahead, so a few details about the route help.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
Do you offer emergency callouts?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we are fully insured.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
Can you fix a faulty AHU?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
When something else is needed
Not every problem is solved by AHU cleaning, and we’ll tell you before work begins. It will not put right:
- Ductwork downstream of the unit, which is a separate clean
- Building management system faults
- Breakdowns that need a mechanical engineer
If you are not sure, just give us a ring on 0345 646 2711 or send us an email and we will give you a straight answer.
