AHU cleaning for kitchens and businesses in Bedfont
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. The work covers internal panels, filter sections and supply and extract fans, and common reasons people get in touch are dirty filters cutting the airflow and coils clogged with dust and debris.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Bedfont, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Part by part
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
How the visit works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes half a day to a full day per unit, with large plant planned over several shifts. For a job in Bedfont, tell us about loading bays, permits, lifts and roof access when you book.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Arrange a key holder or contact on site
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any parking or loading restrictions
Getting a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Once you have those, ring 0345 646 2711 or send us an email.

Do you need AHU cleaning in Bedfont?
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
Any of these means the system needs a check-up:
- Drain trays holding standing water
- Units needing a clean before a new tenant or handover
- Air handling units with blocked filters
- Odours coming through the supply air
Ashford Hospital, about 1.4 miles south-west, is the nearest hospital to Bedfont, and healthcare sites of every size need their supply air kept clean.

FAQs for Bedfont
Can you clean school ventilation in Bedfont during the holidays?
Yes, out-of-term visits are normal for schools. With about 19 schools and colleges on the FSA’s register within roughly a mile and a half of Bedfont, it pays to plan holiday dates ahead. Send us your term dates when you call 0345 646 2711 or send us an email, and we will fit the work in.
Can you come to Bedfont after we close?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
How long does an AHU clean take?
Expect it to take one overnight shift for many single units, with bigger plant phased. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.
What should I send you?
Some pictures and a quick description of the system plus the address and your hours. If we need more, we will ask.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
Are you insured?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Between visits
To keep the system working properly between visits:
- Note any water around the unit or leaks below it
- Change filters on schedule and log each change
- Keep inspection doors on the unit in good order
- Don’t store bins or materials near the intake
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.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
