How we handle AHU cleaning in Adstock
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and send you a fixed quote before any cleaning starts. The work covers supply and extract fans, heating and cooling coils and internal panels, and the jobs we see most are debris and leaves in the fresh air intake and dirty coils holding back the airflow.
Somewhere as small as Adstock, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Do you need AHU cleaning in Adstock?
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Adstock, that is air they breathe for hours at a time.
These are the problems we see most often:
- Drain trays holding standing water
- Filters that are clogged or overdue
- Plant that has been serviced but not cleaned
- Air handling units due a clean after building work
For schools like Padbury Church of England School, the holidays are the usual time to inspect and clean ventilation.

Why act early in Adstock
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Our emergency line runs 24/7, but a planned visit to Adstock is calmer for everyone.
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

AHU cleaning in Adstock: local notes
The FSA’s food hygiene register lists about 4 schools, colleges and universities with registered kitchens or food service across Adstock and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. We cover Adstock, about 48 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours. About 3.5 miles north-west of Adstock is Buckingham Community Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Healthcare buildings such as Buckingham Community Hospital, about 3.5 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Adstock, yours matters too.
Adstock is about 3 miles south-east of Buckingham, in Buckinghamshire.

Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Somewhere like Adstock, lanes, gates and parking are worth mentioning in advance.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- 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.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Mention any parking or loading restrictions
- Have your last certificate or report to hand
Getting a quote
To help us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Then give us a ring on 0345 646 2711 or email us.

What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Honest limits
We’d rather tell you now than book work that won’t help, so here are the limits:
- Airflow problems caused by the system’s design
- Mechanical faults with motors, belts or bearings
- Problems with the unit’s controls or sensors
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we’ll tell you honestly.
Parts of the system we cover

Adstock: your questions answered
Can you work in Adstock outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in Adstock does not have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Do you cover smaller places like Adstock?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
What happens to the waste?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Can you price the work without visiting?
Often, yes. With good photos, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
How much does AHU cleaning cost in Adstock?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll normally reply within one working day.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
What happens if you can’t reach some of it?
We record them on the report, with photos where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
What’s included in an AHU clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
