Chearsley AHU cleaning
AHU cleaning for Chearsley, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Filters that are clogged or overdue
- Coils clogged with dust and debris
- Debris and leaves in the fresh air intake
What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
AHU cleaning in Chearsley
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers internal panels, filter sections and dampers and louvres, and common reasons people get in touch are drain trays holding standing water and air handling units with blocked filters.
Work in a small place like Chearsley starts with agreeing access and timings.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What AHU cleaning cannot fix
A few issues sit outside what this work can do:
- Ventilation that was badly designed in the first place
- Controls and BMS settings that run the unit
- Damaged coils beyond cleaning
If in doubt, give us a ring on 0345 646 2711 or drop us a line and we’ll say what we think before you book.
Where we work
- Internal panels
- Drain trays
- Dampers and louvres
- Heating and cooling coils
- Supply and extract fans
- Filter sections
Do you need AHU cleaning in Chearsley?
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Common reasons sites call us include:
- Dirty filters cutting the airflow
- Units that have only ever had filter changes
- Plant that needs cleaning after a refit
- Dirty coils holding back the airflow
Healthcare ventilation, from large hospitals like Thame Community Hospital (about 3.2 miles south) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before booking
- Whether they recommend a next date
- Whether inaccessible sections are listed on the report
- How VAT is shown on the quote
- Which accreditations they hold, and whether you can check them
How we price AHU cleaning
The survey tells us what the work involves. We look at:
- Whether we need access equipment or extra panels
- What state the system is in
- Parking and loading at the site
- A single visit or a regular plan
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Problems your staff have spotted
- How we’d reach plant on a roof or in a plant room
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, ring 0345 646 2711 or use the quote form.
The process
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Seeing the system in pictures first means the trip to Chearsley can be planned properly.
- 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.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Name a contact who can let us in at the agreed time
- Dig out any earlier paperwork for the system
How to get a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711 or email us.

FAQs for Chearsley
Will you come out to Chearsley?

What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.

Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Where does the waste go?
It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.

Aftercare tips
Once we’ve finished, these simple steps help:
- Keep the certificate and photo report with the plant records
- Watch for drips or damp patches near the plant
- Report stiff or damaged access doors
- Book the next check in line with the report
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
