AHU cleaning in Tandridge
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. If you have rooms that smell stuffy when the system runs and filters that are clogged or overdue, we can put it right, from drain trays, dampers and louvres and filter sections onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Look at the condensate drain whenever the unit is serviced
- Store the TR19 paperwork where auditors can find it
- Report stiff or damaged access doors
- Keep filter changes on time and recorded
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.

Different parts, different methods
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Why deal with it now?
Stuffy rooms and stale smells in a building in Tandridge can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. Rural sites cannot always move to another kitchen or room when something fails.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before we start.
Why us?
- Trading since 2009
- A fixed price before any work starts
- One number for every site across the South East and London
- CHAS and SafeContractor accredited, with ISO 9001

Signs you need AHU cleaning in Tandridge
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Look out for these warning signs:
- Plant that needs cleaning after a refit
- Dirty coils holding back the airflow
- Dirty fans and fan housings
- Plant that has been serviced but not cleaned
Wherever a school like St Peter's CofE Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What we do, step by step
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes from a few hours for a compact unit to a day or more for a large one. If you can send pictures, we can arrive in Tandridge knowing what to expect.
- 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 pictures and issue the certificate and report.
How to prepare
- Dig out any earlier paperwork for the system
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool

FAQs for Tandridge
Can you get to a site in Tandridge?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Can you work in Tandridge outside opening hours?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
What happens if you cannot reach some of it?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
