Bracknell Forest · Air handling unit cleaning
AHU Cleaning in Wooden Hill
One call covers cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Wooden Hill: survey, fixed quote, work and sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Plant that has been serviced but not cleaned
- Dust built up on fan impellers
- Rooms that smell stuffy when the system runs
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 we start, and floors and nearby surfaces are sheeted. On site, it takes one overnight shift for many single units, with bigger plant phased. Somewhere like Wooden Hill, lanes, gates and parking are worth mentioning in advance.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Clear loose items from the work area
- Let us know about parking and loading

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Advice
AHU cleaning for kitchens and businesses in Wooden Hill
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers heating and cooling coils, drain trays and internal panels, and common reasons people get in touch are plant that needs cleaning after a refit and plant that has been serviced but not cleaned.
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.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What affects the quote in Wooden Hill
There’s no set price list, because no two systems are the same. The quote depends on:
- Parking and loading at the site
- One-off work versus a regular cycle
- How big the system is
- The condition we find in the survey
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 unsure, ring 0345 646 2711 or email us for straight advice and a fixed quote.
Helping us quote
To speed up the quote, send us:
- The times we could work without disrupting the site
- Problems your staff have spotted
- Any previous report or certificate
- Wide photos of the system and the area around it
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before we start.
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Keep inspection doors on the unit in good order
- Note any water around the unit or leaks below it
- File each AHU report in the maintenance log
- Report musty smells from the vents straight away
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.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Do you need AHU cleaning in Wooden Hill?
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
The symptoms we’re asked about most include:
- Odours coming through the supply air
- Filters that are clogged or overdue
- Air handling units due a clean after building work
- Dust-coated heating and cooling coils
Healthcare ventilation, from large hospitals like Pinewood Hospital (about 1 mile west) to small clinics, depends on clean filters, coils and ducts.
What your quote should include
- Whether a survey comes first
- Proof of accreditation you can verify
- How areas they cannot reach will be recorded
- Whether VAT is included
What AHU cleaning can’t fix
A few issues sit outside what this work can do:
- Building management system faults
- The supply and extract ducts, quoted separately
- Leaking heating or cooling coils
If you are not sure, just give us a ring on 0345 646 2711, or send details by email and we will give you a straight answer.

A slimy drain tray only gets worse. 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. Our emergency line runs 24/7, but a planned visit to Wooden Hill is calmer for everyone.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before we start.
