When it’s something else

- Faulty motors, drives or bearings
- Problems with the unit’s controls or sensors
- The supply and extract ducts, quoted separately

AHU cleaning in Beggar's Bush, done properly
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. Typical jobs include air handling units never cleaned inside and condensate trays that won’t empty, across filter sections, internal panels and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Your questions about AHU cleaning in Beggar's Bush
Can a school’s ventilation in Beggar's Bush be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. With about 11 schools and colleges on the FSA’s register within roughly a mile and a half of Beggar's Bush, it pays to plan holiday dates ahead. Send us your term dates when you call us on 0345 646 2711 or send us an email, and we’ll fit the work in.
Will you come out to Beggar's Bush?
Yes. Villages and rural sites across the South East are part of our work, Beggar's Bush included. Photos of the system and directions to the site help us plan the visit.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Where does the waste go?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
Can you quote from pictures?
Yes, where the photos show enough. If not, a site survey comes first, and the quote follows that.
Why deal with it now?
If people in a building in Beggar's Bush complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Planning a trip to Beggar's Bush ahead is easier for everyone than a rushed one.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

Looking after it afterwards
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep filter changes on time and recorded
- Plan the next inspection before the last report gets filed away
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
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.

Part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
For landlords and multi-site operators
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. If you can send pictures, we can arrive in Beggar's Bush knowing what to expect.
- 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.
- 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
- Clear loose items from the work area
- Agree a time when the area can be out of use
- Make sure someone can let us in and lock up afterwards
