Air handling unit cleaning in Cox Green, Windsor and Maidenhead
Looking for AHU cleaning in Cox Green? We diagnose first, fix the price and book the work around your hours, then sign off with a report and pictures.
- Air handling units due a clean after building work
- Coils clogged with dust and debris
- Air handling units never cleaned inside
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Make sure condensate is draining away
- Note any water around the unit or leaks below it
- Stick to the filter change plan
- Keep inspection doors on the unit in good order
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
AHU cleaning in Cox Green, done properly
If the units serving a building in Cox Green have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. The work covers dampers and louvres, internal panels and heating and cooling coils, and people most often call us about dust built up on fan impellers and coils clogged with dust and debris.
Around a place like Cox Green, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the visit works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes from a few hours for a compact unit to a day or more for a large one. Tell us when your site near Cox Green is quiet and the visit will be booked for then.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Clear the space around the work
- Tell us about site rules, permits or sign-in

Different parts, different methods
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so you can decide on any repairs.
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.

Questions from Cox Green
Can the work in Cox Green be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. That way a site in Cox Green doesn’t have to lose a day’s trading. When you phone us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Do you cover smaller places like Cox Green?
Yes. Villages and rural sites across the South East are part of our work, Cox Green included. The journey is planned ahead, so a few details about the route help.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We don’t leave it behind.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where necessary. A fixed quote follows.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
What’s included in an AHU clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
What affects the cost of AHU cleaning
We do not publish a price list, because sites vary so much. What we look at:
- A single visit or a regular plan
- The scale of the work
- Working hours and out-of-hours timing
- Parking and loading at the site
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before we start.
What to send for a quote
To speed up the quote, send us:
- Wide pictures of the system and the area around it
- Detail shots of panels, filters and grilles

Why it’s worth doing now in Cox Green
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. You choose the date of a planned visit, and a breakdown never asks.
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.

When something else is needed
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It doesn’t solve:
- Controls and BMS settings that run the unit
- Ventilation that was badly designed in the first place
- Damaged coils beyond cleaning
Not sure which it is? You can ring 0345 646 2711 or use the quote form and we will tell you honestly.
