Bray Wick AHU cleaning

- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
- Filters that are clogged or overdue
What we do, step by step
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 a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Bray Wick, let us know and we will plan around it.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Have your last certificate or report to hand
- Make sure equipment near the work can be switched off and left to cool
- Tell us about site rules, permits or sign-in
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.

AHU cleaning in Bray Wick, done properly
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers heating and cooling coils, drain trays and supply and extract fans, and people most often call us about dirty filters cutting the airflow and rooms that smell stuffy when the system runs.
For a building in or near Bray Wick, access is agreed in advance and the visit is planned around the journey.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Keeping the system healthy
So the system stays in good health:
- Diary the inspection date recommended in the report
- Report water on the plant room floor
- Report stiff or damaged access doors
- Flag stale or damp smells in the supply air
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Honest limits
AHU cleaning cannot fix everything, and we’d rather say so up front. It doesn’t solve:
- The supply and extract ducts, quoted separately
- Building management system faults
- A system that’s undersized for the building
If in doubt, ring 0345 646 2711, or email photos and we will say what we think before you book.
Where we work
- Dampers and louvres
- Filter sections

- Heating and cooling coils
- Internal panels
What staff can safely do
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
FAQs for Bray Wick
Can a school’s ventilation in Bray Wick be done out of term time?
Yes, out-of-term visits are normal for schools. With about 13 schools and colleges on the FSA’s register within roughly a mile and a half of Bray Wick, it pays to plan holiday dates ahead. Send us your term dates when you call us on 0345 646 2711 or use the quote form, and we’ll fit the work in.
Can you work in Bray Wick outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Bray Wick does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
What happens if you cannot reach some of it?
We record them on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, ring 0345 646 2711, or email photos with the site type, opening hours and a few pictures.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with photos where it helps.
What should I send you?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply phone us on 0345 646 2711 or use the quote form.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and the report recommends a next date.
What affects the cost of AHU cleaning
Sites vary more than people expect. What affects the quote:
- Working hours and out-of-hours timing
- A single visit or a regular plan
- Parking and loading at the site
- The scale of the work
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
- A few general shots of the system
- The roof, plant room or outside wall the system runs to
There’s no standard 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 email us.
Why it’s worth doing now in Bray Wick
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Somewhere as small as Bray Wick, losing a kitchen or building to a fault is felt by everyone who uses it.
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

Signs you need AHU cleaning in Bray Wick
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that is where slime and odours start.
Common reasons sites call us are:
- Blocked condensate drains and slimy trays
- Plant that needs cleaning after a refit
- Rooms that smell stuffy when the system runs
- Dirty coils holding back the airflow
Healthcare ventilation, from large hospitals like St Mark's Hospital (about 2.3 miles north-west) to small clinics, depends on clean filters, coils and ducts.
What your quote should include
- Whether the work can be done while the site is closed
- Whether the quote is based on a survey or photos
- Which accreditations they hold, and whether you can check them
- Whether the whole system is included, or only the parts that are easy to reach
