AHU cleaning in Kingston Blount
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. The work covers dampers and louvres, filter sections and heating and cooling coils, and people most often call us about air handling units never cleaned inside and dirty fans and fan housings.
Work in a small place like Kingston Blount starts with agreeing access and timings.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How we price AHU cleaning
We do not publish a price list, because no two systems are the same. What we look at:
- The number of sites or systems
- The scale of the work
- A single visit or a regular plan
- Parking and loading at the site
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
What to send for a quote
To help us quote quickly, send us:
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
- Any access panels or hatches you can see
- How we’d reach plant on a roof or in a plant room
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Why act early in Kingston Blount

One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.

When to call us in Kingston Blount
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Look out for these warning signs:
- Dirty filters cutting the airflow
- Leaves and litter drawn into the unit
- Units needing a clean before a new tenant or handover
- Coils clogged with dust and debris
School buildings such as Aston Rowant Church of England Primary School are normally done in the holidays, so classrooms aren’t disturbed.
Questions to ask before booking
- Whether the whole system is included, or only the parts that are easy to reach
- What insurance they carry

- Which accreditations they hold, and whether you can check them

Questions from Kingston Blount
Do you work at weekends in Kingston Blount?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Kingston Blount needn’t be disturbed. Just call 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Is Kingston Blount in your area for AHU cleaning?
Yes. We work across London and the South East, and Kingston Blount is part of that. Just give us a ring on 0345 646 2711, or email photos with a few details of the site.
How often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
How far ahead should we book?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
What we do, step by step
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Kingston Blount, let us know and we’ll plan around it.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Before we arrive
- Tell us where we can park and unload
- Arrange a key holder or contact on site
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
