Selsfield Common AHU cleaning
Professional AHU cleaning in and around Selsfield Common, booked around your opening hours and finished with a written report and pictures.
- Drain trays holding standing water
- Rooms that smell stuffy when the system runs
- Dust built up on fan impellers
Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Keep the certificate and photo report with the plant records
- Plan the next inspection before the last report gets filed away
- Note any water around the unit or leaks below it
- Look at the condensate drain whenever the unit is serviced
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
How we handle AHU cleaning in Selsfield Common
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. The work covers heating and cooling coils, filter sections and supply and extract fans, and the jobs we see most are dirty fans and fan housings and leaves and litter drawn into the unit.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The sign-off is always in writing: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Do you need AHU cleaning in Selsfield Common?
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
What we are most often called out for:
- Drain trays holding standing water
- Air handling units due a clean after building work
- Stale or musty smells from the ventilation
- Dust-coated heating and cooling coils
Hospitals such as Queen Victoria Hospital (about 4.5 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Selsfield Common are no different.

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 photos. Most of the time goes on the work itself, which takes from a few hours for a compact unit to a day or more for a large one. Seeing the system in pictures first means the trip to Selsfield Common can be planned properly.
- First we agree when the unit can be switched off, including evenings or weekends.
- 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 pictures and issue the certificate and report.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Tell us about site rules, permits or sign-in
- Find the previous report, if there is one

Selsfield Common questions
Will you come out to Selsfield Common?
Yes. Selsfield Common is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Do you work at weekends in Selsfield Common?
Yes, nights and weekends are routine for us. It means the site in Selsfield Common keeps running as normal. Your opening times are the first thing we ask for.
What’s included in an AHU clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and pictures.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Do you look at the system first?
Yes. We always survey first, from your pictures and details, or with a visit where needed. A fixed quote follows.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Different parts, different methods
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.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Why deal with it now?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. A planned visit to Selsfield Common is easier to arrange than an emergency callout.
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.

In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
