Air handling unit cleaning in Uxbridge, Buckinghamshire
We cover Uxbridge for AHU cleaning. Fixed quotes, work around your opening hours and photo reports as standard.
- Condensate trays that will not empty
- Filters that are clogged or overdue
- Air handling units due a clean after building work
Different parts, different methods
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with pictures so repairs can be planned.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
AHU cleaning in Uxbridge, done properly
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. Common call-outs are for blocked condensate drains and slimy trays and leaves and litter drawn into the unit, on supply and extract fans, dampers and louvres and filter sections.
In a smaller place like Uxbridge, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Ventilation in Uxbridge buildings
There are about 26 schools, colleges and universities, about 31 caring premises (care homes, nurseries and hospitals) and about 5 hotels and B&Bs on the FSA’s food hygiene register across Uxbridge and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Hillingdon Hospital is the nearest hospital, about 1.2 miles south-east of Uxbridge. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Uxbridge, about 17 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours.
Healthcare ventilation, from large hospitals like Hillingdon Hospital (about 1.2 miles south-east) to small clinics, depends on clean filters, coils and ducts.

What we do, step by step
Our technicians bring everything the work needs, 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. The visit takes from a few hours for a compact unit to a day or more for a large one. Because the survey comes first, a visit to Uxbridge can usually be finished without a second trip.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Tell us where we can park and unload
- Have your last certificate or report to hand
- Clear the space around the work
How to get a quote
If you need AHU cleaning in Uxbridge, ring 0345 646 2711, or email photos. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. We typically send a fixed quote within one working day.
Related advice
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Make sure the unit’s access doors open easily
- Report water on the plant room floor
- Look at the condensate drain whenever the unit is serviced
- Keep the certificate and photo report with the plant records
When we have closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Fixed quotes for AHU cleaning in Uxbridge
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether several sites go on one quote
- The condition we find in the survey
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.
What we need to know
We can often survey from pictures. The most useful are:
- Problems your staff have spotted
- Any previous report or certificate
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
The quickest way to a quote is to send photos: 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.
When to call us in Uxbridge
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
Keep an eye out for these warning signs:
- Drain trays holding standing water
- Air handling units due a clean after building work
- Air handling units with blocked filters
- Dust-coated heating and cooling coils
If you manage a school such as Whitehall Junior School, ventilation cleaning is best booked for the holidays.
What your quote should include
- Whether the work can be done while the site is closed
- Exactly which parts of the system are covered
- Whether they recommend a next date
- Whether a survey comes first
Common questions in Uxbridge
Do you work overnight in Uxbridge?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Can you get to a site in Uxbridge?
Yes. Villages and rural sites across the South East are part of our work, Uxbridge included. Let us know about access, parking and anything unusual about getting there when you book.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Do you give a certificate after the clean?
Yes, both a certificate and a report with photos. The report also suggests when the unit should next be inspected.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
What about areas you can’t get to?
We record them on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
