AHU Cleaning in Slough Green

Why act early in Slough Green
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Equipment tucked in a roof space or outbuilding near Slough Green rarely gets looked at unless someone books it.
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.

How we handle AHU cleaning in Slough Green
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers internal panels, supply and extract fans and dampers and louvres, and common reasons people get in touch are leaves and litter drawn into the unit and dust built up on fan impellers.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Different parts, different methods
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
What your team can do, and what needs us
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, alongside our reports.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Slough Green: your questions answered
Can you come to Slough Green after we close?
Yes, nights and weekends are routine for us. It means the site in Slough Green keeps running as normal. Just give us a ring on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Do you offer AHU cleaning in Slough Green?
Yes, Slough Green is covered. Just phone us on 0345 646 2711 or use the quote form with a few details of the site.
How long does it take to clean an air handling unit?
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?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
What happens if you cannot reach some of it?
Anything we can’t reach goes on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
Do you clean the ductwork as well?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can quote for both.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Call us any time and explain what’s happened.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.
How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes one overnight shift for many single units, with bigger plant phased. In a small place like Slough Green, the journey is planned ahead and the visit arranged around the site’s hours.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Agree a time when the area can be out of use
- Move anything stored near the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

We don’t publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, phone us on 0345 646 2711 or send us an email.

What AHU cleaning looks like in Slough Green
Food Standards Agency records list about 3 care, childcare and hospital premises registered as food businesses within about 1.5 miles of central Slough Green. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Slough Green, about 33 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site. The Dene Hospital is the nearest hospital, about 3.7 miles south of Slough Green. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Wherever a school like Warden Park School has ducted ventilation, a half-term visit keeps the work out of lesson time. Healthcare buildings such as The Dene Hospital, about 3.7 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Slough Green, yours matters too.
