AHU cleaning for kitchens and businesses in Whitchurch
If the units serving a building in Whitchurch have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. The work covers filter sections, supply and extract fans and drain trays, and people most often call us about blocked condensate drains and slimy trays and dust-coated heating and cooling coils.
Work in a small place like Whitchurch starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Your questions about AHU cleaning in Whitchurch
Can the work in Whitchurch be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. It means the site in Whitchurch keeps running as normal. Your opening times are the first thing we ask for.
Do you work in villages like Whitchurch?
Yes, we work in villages as well as towns, and Whitchurch is covered. Just mention lanes, gates or anything else about the site when you book.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with the details in the report.
Can you quote from photos?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Do you look at the system first?
Yes. We always survey first, from your photos and details, or with a visit where needed. A fixed quote follows.
What information do you need?
Some photos and a quick description of the system, with the address and opening hours. If we need more, we will ask.
When to call us in Whitchurch
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 Whitchurch, that is air they breathe for hours at a time.
These are the problems we see most often:
- Plant that needs cleaning after a refit
- Stale or musty smells from the ventilation
- Air handling units never cleaned inside
- Dirty filters cutting the airflow
For schools like Whitchurch Combined School, the holidays are the usual time to inspect and clean ventilation.
What your quote should include
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- How they set the interval to the next visit
- Whether the figure could change on the day
- Whether the quote is based on a survey or pictures
Why it’s worth doing now in Whitchurch

Staff cleaning versus specialist work
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
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, and that is where we come in.
How it works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Somewhere as small as Whitchurch, the date and timings are agreed with you well before the day.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Move anything stored near the system
- Let us know about parking and loading
Ask for a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before work begins.

What a clean will not put right

- Coils that are corroded or leaking and need replacing
- Airflow problems caused by the system’s design

Part by part
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
