About our AHU cleaning in Coombe
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. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. The work covers drain trays, heating and cooling coils and filter sections, and the jobs we see most are leaves and litter drawn into the unit and fan sections that haven’t been cleaned in years.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Coombe is usually planned out of hours. Loading and parking are planned with the building first.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Honest limits
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Breakdowns that need a mechanical engineer
- A system that’s undersized for the building
- Leaking heating or cooling coils

Multi-site and managed buildings
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Questions from Coombe
Do you clean school ventilation in Coombe in the holidays?
Yes, holiday work suits schools best. The FSA’s register shows about 26 schools and colleges with food registrations within roughly a mile and a half of Coombe. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can parking be tricky for a job in Coombe?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
How much does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
Do you have insurance?
Yes. Full insurance covers our work, and we have been trading since 2009.
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.
Can you price the work without visiting?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
AHU cleaning around Coombe
The FSA’s food hygiene register lists about 26 schools, colleges and universities, about 80 hospitals, care homes and childcare premises and about 10 hotels, B&Bs and guest houses with registered kitchens or food service across Coombe 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. National Psychosis Unit is the nearest hospital, about 2.1 miles north-east of Coombe. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
School buildings such as Coombe Wood School are typically done in the holidays, so classrooms are not disturbed. National Psychosis Unit, about 2.1 miles north-east, is the nearest hospital to Coombe, and healthcare sites of every size need their supply air kept clean.

What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
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.
What affects the quote in Coombe
Your quote is based on your site. We take into account:
- The condition of the system
- How easy every part is to reach
- The times the site is available
- Site rules, permits and inductions
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
- The site address and the type of premises
To help us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711 or send us an email.
Why act early in Coombe
Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Planning ahead in Coombe lets you pick a quiet night rather than lose a busy one.
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.
What you get with us
- A written report with pictures after every visit

What the work involves, part by part
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.

What happens on the day
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Night and weekend working is normal for us in London, and a site in Coombe is no exception.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Have your last certificate or report to hand
- Agree a time when the area can be out of use
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
