AHU cleaning in Donnybrook Quarter, done properly
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. If you are dealing with dirty filters cutting the airflow and dirty fans and fan housings, we can help.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Donnybrook Quarter, dust and debris build up in the units and ductwork over time.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Why it’s worth doing now in Donnybrook Quarter
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.

Different parts, different methods
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
Managing agents and facilities teams in Donnybrook Quarter
We work for landlords, managing agents and facilities managers as well as the people running the site. 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, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.

What to send for a quote
There’s no need for technical detail. It helps if you can send:
- Your last certificate, test record or report
- When the site is open and when it’s quiet
- Problems your staff have spotted
- The postcode and the type of business
To help us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Then give us a ring on 0345 646 2711 or drop us a line.
How it works
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes from a few hours for a compact unit to a day or more for a large one. Most London sites cannot stop for the day, so work in Donnybrook Quarter is normally done overnight, early in the morning or at weekends.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site
Getting a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Note any water around the unit or leaks below it
- File each AHU report in the maintenance log
- Book the next check in line with the report
- Don’t store bins or materials near the intake
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Donnybrook Quarter: your questions answered
Does London parking affect a job in Donnybrook Quarter?
A loading bay, a visitor permit or off-street space near the site in Donnybrook Quarter makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Do you work at weekends in Donnybrook Quarter?
Yes, out-of-hours work is a big part of what we do. The work in Donnybrook Quarter can fit around your hours. When you give us a ring on 0345 646 2711, or email photos, mention when the site is quiet.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we’re fully insured.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
