AHU cleaning in Thame, done properly
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. If you have dust-coated heating and cooling coils and leaves and litter drawn into the unit, we can help.
Buildings in towns like Thame often have ventilation added in stages, with units on the roof or in a plant room. An inspection shows which parts need cleaning.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Fixed quotes for AHU cleaning in Thame
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access, including roofs, risers and ceiling voids
- Working hours and out-of-hours timing
- The condition we find in the survey
- Any permits to work or inductions
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
- Where the site is and what kind of site it is
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Other services in Thame
What happens on the day
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes from a few hours for a compact unit to a day or more for a large one. In a town like Thame, we typically work after closing or on a quiet day, so the site opens again on time.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- 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.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Find the previous report, if there is one
- Make sure someone can let us in and lock up afterwards
Ask for a quote
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before we start.

Why it’s worth doing now in Thame
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, ready to show anyone who asks. A small fault found now is a quick job; the same fault found later can close the site.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before we start.
What you get with us
- Every job surveyed first
- Trading since 2009
- One contact for all your sites in London and the South East
- A fixed price before any work starts
See our cost guide and our accreditations.
Between visits
Simple habits between visits make a real difference. Our advice:
- Flag stale or damp smells in the supply air
- Clear leaves and litter away from the intake
- Stick to the filter change plan
- Keep the certificate and photo report with the plant records
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Part by part
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so repairs can be planned.

Is there a survey before the work?

What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then call 0345 646 2711 or send us an email.
Will we get paperwork for the AHU clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
Can you clean the ducts connected to the AHU?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, with new panels fitted where necessary.
Multi-site and managed buildings
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
When to call us in Thame
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Most sites get in touch after spotting something like this:
- Leaves and litter drawn into the unit
- Air handling units never cleaned inside
- Filters that are clogged or overdue
- Dirty coils holding back the airflow
Wherever a school like Barley Hill Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
