AHU cleaning around Windsor
Food Standards Agency data includes about 52 schools, colleges and universities, about 13 hospitals, care homes and childcare premises and about 12 hotels, B&Bs and guest houses within 1.5 miles or so of the middle of Windsor. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. King Edward VII Hospital is the nearest hospital, about 0.8 miles east of Windsor. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. We cover Windsor, about 23 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours.
Classrooms and halls at schools such as St Edward's Catholic First School are easiest to work in when pupils are away.

AHU cleaning in Windsor, done properly
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and send you a fixed quote, so you know where you stand. If you have intake sections clogged with outdoor debris and dirty fans and fan housings, we can put it right, from internal panels, supply and extract fans and drain trays onwards.
Buildings in towns like Windsor often have ventilation added in stages, with units on the roof or in a plant room. An inspection shows which parts need cleaning, so you are not paying for more than the system needs.
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.

What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Other services in Windsor
Part by part
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Common problems we fix in Windsor
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Clients usually contact us after spotting something like this:
- Air handling units never cleaned inside
- Dirty fans and fan housings
- Blocked condensate drains and slimy trays
- Coils clogged with dust and debris
Hospitals such as King Edward VII Hospital (about 0.8 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Windsor are no different.

What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-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 from a few hours for a compact unit to a day or more for a large one. Work in Windsor is normally booked after closing, early in the morning or on a closed day.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Dig out any earlier paperwork for the system
- Tell us where we can park and unload
How to get a quote
Getting a quote doesn’t take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

What affects the quote in Windsor
We don’t publish a price list, because sites vary so much. What we look at:
- The condition we find in the survey
- Site rules, permits and inductions
- One-off work versus a regular cycle
- Where the site is and how we reach it
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 we’ll price it together.
What we need to know
Before you ask for a quote, gather:
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
- When the site is open and when it’s quiet
- The paperwork from the last visit, if you have it
If you need AHU cleaning in Windsor, ring 0345 646 2711 or send us an email. Let us know the site type and the opening hours, and send pictures or your last report if you can. We typically send a fixed quote within one working day.
Why act early in Windsor
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. If an inspection, an insurer’s survey or a fire risk assessment is coming up in Windsor, having the work done and recorded first helps.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711 or send us an email for straight advice and a fixed quote.
Why us?
- We diagnose before we treat
- Fixed quotes, typically within one working day
- Work around your opening hours, with 24/7 emergency cover
- A written report with photos after every visit
Managing agents and facilities teams in Windsor
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
FAQs for Windsor
Can ventilation in schools around Windsor be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 52 schools and colleges with food registrations within roughly a mile and a half of Windsor. Send us your term dates when you phone us on 0345 646 2711 or send us an email, and we will fit the work in.
Is AHU cleaning available in Windsor?

Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with the details in the report.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
Do you look at the system first?
Yes. Photos often do the job, and larger or hidden systems get a visit.
What happens if you can’t reach some of it?
Anything we cannot reach goes on the report, with photos where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
