AHU cleaning in Sundridge
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. The work covers drain trays, supply and extract fans and heating and cooling coils, and common reasons people get in touch are dirty fans and fan housings and leaves and litter drawn into the unit.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Sundridge is normally planned out of hours. Parking and loading are agreed with the building in advance.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, 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.

What affects the quote in Sundridge
We do not publish a price list, because sites vary so much. The quote depends on:
- The condition we find in the survey
- The size of the system
- Where the site is and how we reach it
- Whether several sites go on one quote
What you pay depends on how big the system is, what state it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.
What to send for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
For a fixed quote, call us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. You’ll typically have a quote within one working day.
When to call us in Sundridge
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Keep an eye out for any of the following:
- Coils clogged with dust and debris
- Leaves and litter drawn into the unit
- Air handling units due a clean after building work
- Units that have only ever had filter changes
Healthcare ventilation, from large hospitals like Bromley Hospital (about 1.4 miles south) to small clinics, depends on clean filters, coils and ducts.
Before you book anyone
- What insurance they carry
- Exactly which parts of the system are covered
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether VAT is included
Leave it or put it right?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. For a site in Sundridge, fitting the work in overnight now is far easier than closing at short notice later.
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before work begins.

Sundridge: your questions answered
Can you work in Sundridge outside opening hours?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Sundridge needn’t be disturbed. Your opening times are the first thing we ask for.
How do you handle parking and loading in Sundridge?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, usually makes it simpler.
Can you quote from pictures?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What information do you need?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then ring 0345 646 2711, or email photos.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
How long will the unit be out of action?
Cleaning takes anything from half a day for one small unit to several shifts for a plant room full of them. Large plant can be split over several shifts, and you can call 0345 646 2711 or send us an email to plan it.
Do you need to switch the unit off?
Yes. We can’t clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.

Landlords, agents and facilities managers
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.

Ventilation in Sundridge buildings
Going by the FSA’s register, there are about 18 schools, colleges and universities, about 45 care, childcare and hospital premises and about 6 hotels, B&Bs and guest houses serving food across Sundridge and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. The nearest hospital to Sundridge is Bromley Hospital, about 1.4 miles south. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
For schools like St Joseph's Catholic Primary School, the holidays are the usual time to inspect and clean ventilation. If you manage shops or offices close to Sundridge Park station, a TR19® Air inspection shows whether the ductwork needs cleaning.

Aftercare tips
How long the results last depends on use and care. We suggest:
- File each AHU report in the maintenance log
- Check the drain tray is emptying during routine visits
- Diary the inspection date recommended in the report
- Flag stale or damp smells in the supply air
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
