Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
AHU cleaning in Bobbing
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. The work covers supply and extract fans, filter sections and internal panels, and people most often call us about intake sections clogged with outdoor debris and dirty filters cutting the airflow.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes one overnight shift for many single units, with bigger plant phased. A few photos of the system help us make the most of a visit to a place like Bobbing.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Mention any parking or loading restrictions
- Move anything stored near the system
Getting a quote
Getting a quote doesn’t take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

When to call us in Bobbing
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Any of these means the system needs a check-up:
- Debris and leaves in the fresh air intake
- Odours coming through the supply air
- Dirty coils holding back the airflow
- Fan sections that haven’t been cleaned in years
School buildings such as Grove Park Primary School are normally done in the holidays, so classrooms are not disturbed.
What your quote should include
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the figure could change on the day
- Whether a survey comes first
- When the next visit should be, and why

What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.

Fixed quotes for AHU cleaning in Bobbing
Every site gets its own quote. These are the things that affect it:
- The condition of the system
- Parking and loading at the site
- The number of sites or systems
- Site rules, permits and inductions
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.
What we need to know
To speed up the quote, send us:
- The postcode and the type of business
- Your last certificate, test record or report

For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.

Bobbing questions
Do you clean school ventilation in Bobbing in the holidays?
Yes, and it’s the easiest time to do it. With about 9 schools and colleges on the FSA’s register within roughly a mile and a half of Bobbing, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you work at weekends in Bobbing?
Yes, evening, overnight and weekend work is normal for us. That way a site in Bobbing does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
How long does it take to clean an air handling unit?
Expect it to take anything from half a day for one small unit to several shifts for a plant room full of them. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
What if parts of the system can’t be reached?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.
When should our AHU next be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
Leave it or put it right?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. Equipment tucked in a roof space or outbuilding near Bobbing rarely gets looked at unless someone books it.
The cost depends on the size of the system, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.
