AHU cleaning for kitchens and businesses in Bearton
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you are dealing with coils clogged with dust and debris and drain trays holding standing water, we can help, from dampers and louvres, heating and cooling coils and supply and extract fans onwards.
In a smaller place like Bearton, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Common problems we fix in Bearton
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Keep an eye out for these warning signs:
- Units that have only ever had filter changes
- Dust-coated heating and cooling coils
- Filters that are clogged or overdue
- Drain trays holding standing water
Healthcare buildings such as Fairfield Hospital, about 3.4 miles north-east, depend on their ventilation; if you manage a surgery, clinic or care home near Bearton, yours matters too.

The process
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. For a site near Bearton, the work is booked around your opening hours, evenings and weekends included.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Tell us where we can park and unload
- Tell us about site rules, permits or sign-in
- Allow time for equipment near the work to be turned off and cool down

What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Site requirements such as sign-in and permits
- What state the system is in
- How big the system is
- When the work can happen, such as evenings, overnight or weekends
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before we start.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Where the site is and what kind of site it is
- Close-ups of filters, grilles, hatches or access panels
- The roof, plant room or outside wall the system runs to
- Problems your staff have spotted
To help us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or email us.

Can you come to Bearton after we close?
Yes, evening, overnight and weekend work is normal for us. The work in Bearton can fit around your hours. When you give us a ring on 0345 646 2711, or send details by email, mention when the site is quiet.
Do you cover smaller places like Bearton?

Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply phone us on 0345 646 2711 or drop us a line.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.

Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.

Does the AHU have to be shut down for cleaning?
Yes, for the time we’re working on it. We can work evenings, overnight or at weekends to keep disruption down.
Bearton buildings and their air
Food Standards Agency records list about 16 schools, colleges and universities, about 30 care, childcare and hospital premises and about 4 hotels and guest houses registered as food businesses within 1.5 miles or so of the middle of Bearton. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For Bearton, the closest hospital is Fairfield Hospital, roughly 3.4 miles north-east. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. At about 33 miles from central London, Bearton sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you.
If you manage a school such as Oughton Primary and Nursery School, ventilation cleaning is best booked for the holidays.

What staff can safely do
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’s where we come in.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Why it’s worth doing now in Bearton
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. In a smaller place like Bearton, a site that has to close is felt quickly.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.

Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Change filters on schedule and log each change
- Check the drain tray is emptying during routine visits
- Clear leaves and litter away from the intake
- Store the TR19 paperwork where auditors can find it
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
