AHU cleaning for kitchens and businesses in Hollywater
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. We are often asked to deal with plant that has been serviced but not cleaned and dust built up on fan impellers, across supply and extract fans, internal panels and heating and cooling coils.
For a building in or near Hollywater, access is agreed in advance and the visit is planned around the journey.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Between visits
Here’s the after-treatment advice, in brief:
- Stick to the filter change plan
- Do not ignore odours coming through the grilles
- Book the next check in line with the report
- Look at the condensate drain whenever the unit is serviced
We recommend when the unit should next be inspected or cleaned, based on what we found. 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. Once filters clog, dirt starts getting past them.
Common questions in Hollywater
Can you come to Hollywater after we close?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you phone us on 0345 646 2711 or email us, mention when the site is quiet.
Can you clean school ventilation in Hollywater during the holidays?
Yes. The holidays are the usual time for school work. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hollywater. Booking early in the term gives the best choice of holiday dates.
Are you insured?
Yes. We’re fully insured, and the details are available on request.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
How long will the unit be out of action?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, including evenings or weekends.
What’s included in an AHU clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
Do you look at the system first?
Yes. We always survey first, either from pictures and details you send or on a site visit. A fixed quote follows.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
AHU cleaning in Hollywater: local notes
Food Standards Agency records list about 8 caring premises (care homes, nurseries and hospitals) registered as food businesses within 1.5 miles or so of the middle of Hollywater. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. At about 43 miles from central London, Hollywater sits well inside the area we cover. The visit is fixed around your opening hours, not ours. The nearest hospital to Hollywater is Chase Community Hospital, about 0.6 miles north-west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Wherever a school like Woodlea Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

How the visit works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. Rural roads and tight entrances are worth telling us about before a visit to Hollywater.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Find the previous report, if there is one
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us where we can park and unload

Advice
Leave it or put it right?
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. In a small place like Hollywater, a system that fails can take a site out of use.
You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711, or email photos, and we’ll explain what it covers.

What affects the quote in Hollywater
We quote each job individually. These are the things that affect it:
- The number of sites or systems
- When the work can happen, such as evenings, overnight or weekends
- Site requirements such as sign-in and permits
- How big the system is
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
What we need to know
You don’t need the technical terms. Just send:
- Your last certificate, test record or report
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your opening hours and when the area is out of use
- A few general shots of the system
For a fixed quote, phone us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We normally come back within one working day.

What we’re called out for in Hollywater
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
If you notice any of these, it’s worth a diagnosis:
- Dirty fans and fan housings
- Blocked condensate drains and slimy trays
- Stale or musty smells from the ventilation
- Air handling units with blocked filters
Chase Community Hospital, about 0.6 miles north-west, is the nearest hospital to Hollywater, and healthcare sites of every size need their supply air kept clean.
