How we handle AHU cleaning in Ashburton
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. If you have coils clogged with dust and debris and units needing a clean before a new tenant or handover, we can help, from filter sections, dampers and louvres and internal panels onwards.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Ashburton is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Do not ignore odours coming through the grilles
- Diary the inspection date recommended in the report
- Keep filter changes on time and recorded
- Keep inspection doors on the unit in good order
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Part by part
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
Why it’s worth doing now in Ashburton
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. A building in Ashburton may have flats or offices above and alongside, and a fault in the system can affect them too.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before any work starts.

Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
What your team can do, and what needs us
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. Reaching it takes a specialist with the right equipment.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
What AHU cleaning looks like in Ashburton
Going by the FSA’s register, there are about 20 schools, colleges and universities, about 81 hospitals, care homes and childcare premises and about 6 hotels, B&Bs and guest houses serving food across Ashburton 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. 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 1.7 miles east of Ashburton. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
School buildings such as St Thomas Becket Catholic Primary School are normally done in the holidays, so classrooms aren’t disturbed. If you manage offices or shops near Norwood Junction station, their ventilation can be inspected and cleaned out of hours. Healthcare ventilation, from large hospitals like National Psychosis Unit (about 1.7 miles east) to small clinics, depends on clean filters, coils and ducts.

Common questions in Ashburton
Can you clean school ventilation in Ashburton during the holidays?
Yes, holiday work suits schools best. With about 20 schools and colleges on the FSA’s register within roughly a mile and a half of Ashburton, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can the work in Ashburton be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Ashburton keeps running as normal. Your opening times are the first thing we ask for.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and we’ll quote them together.
Do you clean the ductwork as well?
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.
Is a quote from photos possible?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. If photos aren’t enough, we’ll survey first.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it doesn’t spread.
What a clean will not put right
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Ductwork downstream of the unit, which is a separate clean
- Problems with the unit’s controls or sensors
- Faulty motors, drives or bearings
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly before booking.
What the work covers
- Heating and cooling coils
- Dampers and louvres
- Supply and extract fans
- Filter sections

How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes one overnight shift for many single units, with bigger plant phased. A name and number for whoever controls access to the building in Ashburton saves time on the night.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Clear loose items from the work area
- Find the previous report, if there is one
- Arrange a key holder or contact on site
