AHU cleaning in Frindsbury
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. Typical jobs include units that have only ever had filter changes and coils clogged with dust and debris, on drain trays, dampers and louvres and supply and extract fans.
In a place like Frindsbury, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What the work involves, part by part
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.

What else we do in Frindsbury
Why deal with it now?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. A planned visit to Frindsbury fits your hours; an emergency doesn’t.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.

- A written report with pictures after every visit

What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Aftercare tips
Here’s the after-treatment advice, in brief:
- File each AHU report in the maintenance log
- Make sure condensate is draining away
- Watch for drips or damp patches near the plant
- Don’t ignore odours coming through the grilles
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Your questions about AHU cleaning in Frindsbury
Do you clean school ventilation in Frindsbury in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Frindsbury, the Food Standards Agency lists about 16 schools and colleges with registered kitchens within a mile and a half or so. Just call 0345 646 2711, or email photos with your term dates and we will plan around them.
Do you work in villages like Frindsbury?
Yes, smaller places are covered as well as towns. A survey first, from photos or a visit, means we arrive with the right kit.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then give us a ring on 0345 646 2711 or email us.
Can you clean the AHU out of hours?
Yes. We work evenings, overnight and weekends, so the building keeps running in the day.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
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.
How do you keep the site clean during the work?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What affects the cost of AHU cleaning
A fixed price needs a few facts first. We look at:
- A single visit or a regular plan
- Whether we need access equipment or extra panels
- Site rules, permits and inductions
- Parking and loading at the site
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- A few general shots of the system
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before work begins.
The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, which takes anything from half a day for one small unit to several shifts for a plant room full of them. For a site near Frindsbury, the work is booked around your opening hours, evenings and weekends included.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Arrange a key holder or contact on site
- Move anything stored near the system
Getting a quote
Getting a quote does not take long. Call or email with a few details and you will typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
