How we handle AHU cleaning in Langley
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. We’re often asked to deal with dust-coated heating and cooling coils and units that have only ever had filter changes, across drain trays, supply and extract fans and filter sections.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
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, and we’re fully insured.

Managing agents and facilities teams in Langley
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
What AHU cleaning looks like in Langley
The FSA’s food hygiene register lists about 8 schools, colleges and universities and about 5 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service in and around Langley, up to about a mile and a half out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. At about 34 miles from central London, Langley sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site. KIMS hospital is the nearest hospital, about 3.6 miles north of Langley. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you run a surgery, dental practice or care home near Langley, clean ventilation matters as much to you as to a hospital like KIMS hospital (about 3.6 miles north).

Common problems we fix in Langley
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:
- Units that have only ever had filter changes
- Dirty fans and fan housings
- Rooms that smell stuffy when the system runs
- Dirty filters cutting the airflow
Classrooms and halls at schools such as Langley Park Primary Academy are easiest to work in when pupils are away.
What your quote should include
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the quote is based on a survey or pictures
- Whether they recommend a next date
- Whether inaccessible sections are listed on the report
Between visits
A little care between visits keeps the system in better shape. Our advice:
- Report stiff or damaged access doors
- Plan the next inspection before the last report gets filed away
- Watch for drips or damp patches near the plant
- Change filters on schedule and log each change
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
The process
A visit follows the same order every time: protect the area, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. If you can send photos, we can arrive in Langley knowing what to expect.
- We look at the unit and the plant area during the survey.
- 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.
Getting ready for the visit
- Mention any parking or loading restrictions
- Clear loose items from the work area
- Have your last certificate or report to hand
Get a fixed quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Your questions about AHU cleaning in Langley
Will you come out to Langley?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you clean school ventilation in Langley during the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 8 schools, colleges and universities with registered kitchens within about a mile and a half of Langley. You can call 0345 646 2711 or use the quote form with the dates the site is empty.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after pictures. Keep them in the maintenance log.
Can you fix a faulty AHU?
We clean the unit and flag faults rather than repair them, with the details in the report.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Is there a survey before the work?
Yes. We always survey first, either from pictures and details you send or on a site visit. A fixed quote follows.
Do you clean the ductwork as well?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
