About our AHU cleaning in Barnes Street
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. The work covers drain trays, filter sections and supply and extract fans, and people most often call us about air handling units with blocked filters and coils clogged with dust and debris.
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.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What we’re called out for in Barnes Street
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Clients usually contact us when they notice one of these:
- Leaves and litter drawn into the unit
- Dirty filters cutting the airflow
- Dust-coated heating and cooling coils
- Stale or musty smells from the ventilation
Healthcare ventilation, from large hospitals like Tonbridge Cottage Hospital (about 4 miles south-west) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before booking
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- When the next visit should be, and why
- Whether the quote is based on a survey or photos
- Whether they’re fully insured
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
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. The inside of ducts and units needs a specialist.
Why act early in Barnes Street
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Systems in rural buildings are often out of sight and out of mind.
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
Why Barnes Street businesses choose us
- One number for every site across the South East and London
- CHAS, SafeContractor and ISO 9001
- Evenings, overnight and weekends, plus 24/7 emergency callout
- We diagnose before we treat
Between visits
Results last longer with the right care. Here’s what we suggest:
- Keep inspection doors on the unit in good order
- Stick to the filter change plan
- Keep the certificate and photo report with the plant records
- Plan the next inspection before the last report gets filed away
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.

Food Standards Agency records list about 6 schools, colleges and universities and about 3 caring premises (care homes, nurseries and hospitals) registered as food businesses across Barnes Street and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Barnes Street’s nearest hospital, Tonbridge Cottage Hospital, is about 4 miles south-west.

How the visit works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before any work starts, and the area around the work is covered and protected. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Barnes Street, the date and timings are agreed with you well before the day.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
How to prepare
- Name a contact who can let us in at the agreed time
- Let us know about permits to work or site inductions
- Tell us where we can park and unload
