AHU Cleaning in Winsor
AHU cleaning across Winsor and nearby, booked around your opening hours and finished with a written report and pictures.
- Fan sections that haven’t been cleaned in years
- Filters that are clogged or overdue
- Blocked condensate drains and slimy trays
What we’re called out for in Winsor
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Any of these means the system needs a check-up:
- Dust built up on fan impellers
- Condensate trays that won’t empty
- Dust-coated heating and cooling coils
- Air handling units due a clean after building work
If you run a surgery, dental practice or care home near Winsor, clean ventilation matters as much to you as to a hospital like Tatchbury Mount Hospital (about 1 mile east).

About our AHU cleaning in Winsor
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. The work covers drain trays, filter sections and internal panels, and the jobs we see most are dirty fans and fan housings and air handling units never cleaned inside.
In a village or hamlet like Winsor, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Questions from Winsor
Can you work in Winsor outside opening hours?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Winsor needn’t be disturbed. Just give us a ring on 0345 646 2711, or send details by email with your opening times and we will plan around them.
Can ventilation in schools around Winsor be cleaned out of term?
Yes, out-of-term visits are normal for schools. Around Winsor, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Just call 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
Can you price the work without visiting?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. If pictures are not enough, we’ll survey first.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and leave the area clean.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
What should I send you?
A short description and a few photos plus the address and your hours. We will ask for anything else we need.
Why it’s worth doing now in Winsor
Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Systems in rural buildings are often out of sight and out of mind.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, call us on 0345 646 2711 or email us for straight advice and a fixed quote.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Fixed quotes for AHU cleaning in Winsor
The diagnosis comes before the price. The main factors are:
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
- Site rules, permits and inductions
- Parking and loading at the site
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- Any access panels or hatches you can see
- Where the site is and what kind of site it is
- A few general shots of the system
- Your last certificate, test record or report
We don’t publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, call 0345 646 2711 or use the quote form.
What AHU cleaning can’t fix
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Faulty motors, drives or bearings
- Coils that are corroded or leaking and need replacing
- Problems with the unit’s controls or sensors
If you’re not sure, just call us on 0345 646 2711 or email us and we’ll give you a straight answer before booking.

- Heating and cooling coils
- Supply and extract fans
- Filter sections
- Dampers and louvres
- Drain trays
- Internal panels
What happens on the day
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. On site, it takes anything from half a day for one small unit to several shifts for a plant room full of them. A few pictures of the system help us make the most of a visit to a place like Winsor.
- 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, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Tell us where we can park and unload
- Tell us about site rules, permits or sign-in
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
