Greater London · Air handling unit cleaning
Air handling unit cleaning in Streatham, Greater London
AHU cleaning in Streatham from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Air handling units never cleaned inside
- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
Why deal with it now?
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. In Streatham, a planned overnight visit is much easier than closing unexpectedly.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

About our AHU cleaning in Streatham
Our AHU cleans for sites in Streatham 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. We’re often asked to deal with fan sections that haven’t been cleaned in years and coils clogged with dust and debris, on filter sections, internal panels and heating and cooling coils.
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 Streatham, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
Good records are part of the job. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

What the work involves, part by part
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.
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
When it’s something else
AHU cleaning can’t fix everything, and we’ll tell you before work begins. It will not put right:
- Breakdowns that need a mechanical engineer
- Damaged coils beyond cleaning
- Building management system faults
Not sure which it is? You can ring 0345 646 2711 or use the quote form and we will tell you honestly before you book.
What the work covers
- Drain trays
- Heating and cooling coils
- Dampers and louvres
- Supply and extract fans
- Internal panels
- Filter sections
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: 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.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

What else we do in Streatham
Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
How it works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Getting kit into a London building takes planning, so let us know where we can load and park in Streatham.
- 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 pictures.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Move anything stored near the system
- Make sure someone can let us in and lock up afterwards

Questions from Streatham
Can a school’s ventilation in Streatham be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Around Streatham, the Food Standards Agency lists about 30 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
What do you need to know about parking in Streatham?
Tell us where a van can stop near your site in Streatham, and about any building rules on loading. Night visits tend to make loading easier on London streets.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
Are you fully insured?
Yes. We carry full insurance, and we’ve been trading since 2009.
What if parts of the system cannot be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
How often do AHUs need cleaning?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
