AHU Cleaning in Gunnersbury
AHU cleaning for Gunnersbury, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Air handling units due a clean after building work
- Air handling units with blocked filters
- Coils clogged with dust and debris
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
AHU cleaning for kitchens and businesses in Gunnersbury
Where a building in Gunnersbury has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. The work covers internal panels, drain trays and heating and cooling coils, and common reasons people get in touch are dirty filters cutting the airflow and units that have only ever had filter changes.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Gunnersbury is usually planned out of hours. Parking and loading are agreed with the building in advance.
We have 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 carry full insurance.

What else we do in Gunnersbury
Why act early in Gunnersbury
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, ready to show anyone who asks. London sites work long hours, and the longer a job is left, the bigger it gets.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and the price is agreed before any work starts.
Why Gunnersbury businesses choose us
- Fixed quotes from a survey or pictures
- One number for every site across the South East and London
- Ventilation hygiene specialists since 2009
- Out-of-hours work and a 24/7 emergency line

Looking after it afterwards
Once we have finished, these simple steps help:
- Note any water around the unit or leaks below it
- Keep the area around the fresh air intake clear
- Flag stale or damp smells in the supply air
- Keep filter changes on time and recorded
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
Do you need AHU cleaning in Gunnersbury?
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
These are the problems we see most often:
- Units that have only ever had filter changes
- Fan sections that haven’t been cleaned in years
- Leaves and litter drawn into the unit
- Drain trays holding standing water
If you manage shops or offices close to Gunnersbury station, a TR19® Air inspection shows whether the ductwork needs cleaning.

What happens on the day
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 floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Gunnersbury.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Clear loose items from the work area
- Let us know how we reach the system, including roofs, risers and plant rooms
- Find the previous report, if there is one

Gunnersbury: your questions answered
Is parking a problem for work in Gunnersbury?
Tell us where a van can stop near your site in Gunnersbury, and about any building rules on loading. Night visits tend to make loading easier on London streets.
Do you work at weekends in Gunnersbury?
Yes, out-of-hours work is a big part of what we do. It means the site in Gunnersbury keeps running as normal. Let us know the hours you are closed and we will book within them.
How do you protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
How long does it take to clean an air handling unit?
It takes anything from half a day for one small unit to several shifts for a plant room full of them. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Do you cover Gunnersbury?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Gunnersbury.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
AHU cleaning around Gunnersbury
Food Standards Agency data includes about 40 schools, colleges and universities, about 66 caring premises (care homes, nurseries and hospitals) and about 10 hotels, B&Bs and guest houses in Gunnersbury and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. London plant rooms are often on roofs or in basements reached through occupied floors. The nearest hospital to Gunnersbury is Barnes Hospital, about 2 miles south-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Wherever a school like Strand-on-the-Green Junior School has ducted ventilation, a half-term visit keeps the work out of lesson time. Healthcare ventilation, from large hospitals like Barnes Hospital (about 2 miles south-east) to small clinics, depends on clean filters, coils and ducts.
