How we price AHU cleaning
You will get a fixed price before any work starts. It takes into account:
- Site requirements such as sign-in and permits
- How easy every part is to reach
- What state the system is in
- A single visit or a regular plan
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.
What to send for a quote
We can often survey from photos. The most useful are:
- Photos showing the whole system and its surroundings
- When the site is open and when it’s quiet
- Where the site is and what kind of site it is
- Any access panels or hatches you can see
For a fixed quote, call us on 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You will normally have a quote within one working day.
About our AHU cleaning in West Challow
If the units serving a building in West Challow have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. We’re often asked to deal with drain trays holding standing water and dirty fans and fan housings, across dampers and louvres, supply and extract fans and heating and cooling coils.
Somewhere as small as West Challow, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Common questions in West Challow
Can you come to West Challow after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in West Challow does not have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
Can you clean school ventilation in West Challow during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of West Challow. Send us your term dates when you phone us on 0345 646 2711, or send details by email, and we will fit the work in.
How long does it take to clean an air handling unit?
Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Large plant can be split over several shifts, so call us on 0345 646 2711 or send us an email to talk it through.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Do you clean the ductwork as well?
Yes, the ductwork, grilles and diffusers the unit serves. We’ll tell you after the survey whether the ducts need it.
Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
What happens if you can’t reach some of it?
We record them on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
Why deal with it now?
If people in a building in West Challow complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. Our emergency line runs 24/7, but a planned visit to West Challow is calmer for everyone.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
Why book with us

- Fixed quotes, usually within one working day
- A written report with pictures after each visit
- CHAS and SafeContractor accredited, with ISO 9001
In-house cleaning or a specialist?
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Store the TR19 paperwork where auditors can find it
- Report water on the plant room floor
- Report stiff or damaged access doors
- Diary the inspection date recommended in the report
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Honest limits
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Ventilation that was badly designed in the first place
- Coils that are corroded or leaking and need replacing
- Dirty ducts beyond the unit itself
If you’re not sure, just call us on 0345 646 2711 or email us and we’ll give you a straight answer before you book.

Multi-site and managed buildings
