Greater London · Air handling unit cleaning
Air handling unit cleaning in Gipsy Hill, Greater London
AHU cleaning across Gipsy Hill and nearby, timed so the site keeps working and finished with a written report and photos.
- Dust-coated heating and cooling coils
- Air handling units due a clean after building work
- Dirty filters cutting the airflow
What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
The cost depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.

AHU cleaning in Gipsy Hill, done properly
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you have dust-coated heating and cooling coils and units that have only ever had filter changes, we can put it right, from dampers and louvres, filter sections and drain trays onwards.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Gipsy Hill, dust and debris build up in the units and ductwork over time.
We’ve 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 carry full insurance.

Ventilation in Gipsy Hill buildings
Food Standards Agency records list about 34 schools, colleges and universities, about 77 caring premises (care homes, nurseries and hospitals) and about 3 hotels and B&Bs registered as food businesses in and around Gipsy Hill, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot. St Christopher's Hospice is the nearest hospital, about 1.2 miles east of Gipsy Hill. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
St Christopher's Hospice, about 1.2 miles east, is the nearest hospital to Gipsy Hill, and healthcare sites of every size need their supply air kept clean. School buildings such as Paxton Primary School are typically done in the holidays, so classrooms aren’t disturbed.

What affects the quote in Gipsy Hill
A fixed price needs a few facts first. We look at:
- What state the system is in
- The scale of the work
- Working hours and out-of-hours timing
- Site requirements such as sign-in and permits
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.
Helping us quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- The paperwork from the last visit, if you have it
- The site address and the type of premises
- When the site is open and when it’s quiet
- Wide pictures of the system and the area around it
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
What the work involves, part by part
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
How the visit works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Expect the work in Gipsy Hill to happen after your last customer leaves, not during trading.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Clear the space around the work
- Tell us where we can park and unload
- Name a contact who can let us in at the agreed time

Do you need AHU cleaning in Gipsy Hill?
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Gipsy Hill, that is air they breathe for hours at a time.
These are the problems we see most often:
- Units needing a clean before a new tenant or handover
- Intake sections clogged with outdoor debris
- Rooms that smell stuffy when the system runs
- Coils clogged with dust and debris
If you manage shops or offices close to Gipsy Hill station, a TR19® Air inspection shows whether the ductwork needs cleaning.

Gipsy Hill questions
Can you work in Gipsy Hill outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The work in Gipsy Hill can fit around your hours. Tell us your opening hours when you ask for a quote.
Do you clean school ventilation in Gipsy Hill in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 34 schools and colleges on the FSA’s register within roughly a mile and a half of Gipsy Hill, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
Will the ventilation be off while you clean?
Yes, for the time we’re working on it. We can work evenings, overnight or at weekends so the building is not left without ventilation when it’s busy.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, call us on 0345 646 2711 or send us an email and tell us about the site and its opening hours.
Is there a survey before the work?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
How often do AHUs need cleaning?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
