AHU cleaning for kitchens and businesses in Tinsley Green
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. The work covers supply and extract fans, dampers and louvres and drain trays, 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, which makes them easy to overlook.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

FAQs for Tinsley Green
Can ventilation in schools around Tinsley Green be cleaned out of term?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 5 schools, colleges and universities with registered kitchens within about a mile and a half of Tinsley Green. You can call 0345 646 2711, or send details by email with the dates the site is empty.
Will you come out to Tinsley Green?
Yes. Tinsley Green 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.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and we’ll quote them together.
What happens to the waste?
It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.
Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, with new panels fitted where needed.
What if parts of the system can’t be reached?
Anything we can’t reach goes on the report, with pictures where possible, and we explain what access is needed, such as extra access panels in ductwork.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

How the visit works
The visit has three parts: 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. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. For a village or hamlet like Tinsley Green, tell us about narrow lanes, gates and parking when you book.
- 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.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Move anything stored near the system
Getting a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Part by part
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.
Do you need AHU cleaning in Tinsley Green?
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
These are the problems we see most often:
- Stale or musty smells from the ventilation
- Dirty filters cutting the airflow
- Dust built up on fan impellers
- Dust-coated heating and cooling coils
If you manage a school such as Forge Wood Primary School, ventilation cleaning is best booked for the holidays.

Aftercare tips
Results last longer with the right care. Here’s what we suggest:
- Report stiff or damaged access doors
- Check the drain tray is emptying during routine visits
- Note any water around the unit or leaks below it
- Report musty smells from the vents straight away
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
