Air handling unit cleaning in Marlow, Buckinghamshire

- Units needing a clean before a new tenant or handover
- Leaves and litter drawn into the unit
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
How we handle AHU cleaning in Marlow
We clean air handling units for buildings in Marlow and across Buckinghamshire, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Typical jobs include condensate trays that won’t empty and leaves and litter drawn into the unit, on dampers and louvres, drain trays and supply and extract fans.
In Marlow, ventilation in schools and offices is cleaned when the building is quiet: out of hours, at weekends or during the holidays.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Multi-site and managed buildings
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 photos, so each one has its own record.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.

Questions from Marlow
Is AHU cleaning available in Marlow?
Yes, Marlow is within the area we cover across London and the South East. To start, call 0345 646 2711, or email photos with a few photos of the system.
Do you do school ventilation cleaning in Marlow in the summer holidays?
Yes. The holidays are the usual time for school work. With about 8 schools and colleges on the FSA’s register within roughly a mile and a half of Marlow, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
What information do you need?
The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
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 any work starts.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
When to call us in Marlow
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
What we’re most often called out for:
- Filters that are clogged or overdue
- Rooms that smell stuffy when the system runs
- Units needing a clean before a new tenant or handover
- Plant that has been serviced but not cleaned
If you manage shops or offices close to Marlow station, a TR19® Air inspection shows whether the ductwork needs cleaning.

How the visit works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before we start, and the area around the work is covered and protected. The work itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Before the visit, a few pictures of the system and how to reach it help us plan the work in Marlow.
- We survey the unit from pictures or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend
- Let us know how we reach the system, including roofs, risers and plant rooms
Ask for a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or drop us a line.
Advice
Different parts, different methods
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
Why deal with it now?
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. A small fault found now is a quick job; the same fault found later can close the site.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.

What AHU cleaning looks like in Marlow
Food Standards Agency data includes about 8 schools, colleges and universities, about 15 care, childcare and hospital premises and about 5 hotels and guest houses in and around Marlow, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 30 miles out from central London, Marlow is part of the South East area we work across. Evening, overnight and weekend visits are all possible. Marlow Community Hospital is the nearest hospital, about under half a mile east of Marlow. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Classrooms and halls at schools such as Holy Trinity Church of England (Aided) School are easiest to work in when pupils are away. Hospitals such as Marlow Community Hospital (about under half a mile east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Marlow are no different.
