AHU cleaning in Clifton
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. We are often asked to deal with dirty filters cutting the airflow and fan sections that haven’t been cleaned in years, on filter sections, supply and extract fans and heating and cooling coils.
For a building in or near Clifton, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
A written report with photos follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
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.
Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so each one has its own record.

Why act early in Clifton
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. It’s simpler to plan the work at Clifton now than to arrange it in a hurry later.
The cost depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.

Aftercare tips
Here’s the after-treatment advice, short and simple:
- Keep the certificate and photo report with the plant records
- Make sure the unit’s access doors open easily
- Clear leaves and litter away from the intake
- Look at the condensate drain whenever the unit is serviced
When we have closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
FAQs for Clifton
Do you do school ventilation cleaning in Clifton in the summer holidays?
Yes, holiday work suits schools best. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Clifton. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you work in Clifton outside opening hours?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Clifton needn’t be disturbed. When you ring 0345 646 2711 or email us, mention when the site is quiet.
How far ahead should we book?
Earlier is better, particularly for night and weekend visits. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
Do you give a certificate after the clean?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Can you clean the ducts connected to the AHU?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, with new panels fitted where needed.
What we are called out for in Clifton
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Clifton, that’s air they breathe for hours at a time.
It’s time to book a visit if you see:
- Intake sections clogged with outdoor debris
- Blocked condensate drains and slimy trays
- Air handling units with blocked filters
- Odours coming through the supply air
For buildings in and around Clifton, TR19® Air cleaning starts with an inspection.
What to look for in a quote
- Whether the figure could change on the day
- Which accreditations they hold, and whether you can check them
- Whether the whole system is included, or only the parts that are easy to reach
- Whether a survey comes first
When something else is needed
We won’t sell you work that does not address the problem, so these are the things it won’t cover:
- The supply and extract ducts, quoted separately
- Breakdowns that need a mechanical engineer
- A system that is undersized for the building
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we will tell you honestly before you book.

How the visit works
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes from a few hours for a compact unit to a day or more for a large one, and the area is cleaned down before we leave. A quick note on how to find the site and where to park makes a visit to Clifton run smoothly.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Find the previous report, if there is one
- Allow time for equipment near the work to be turned off and cool down
- Tell us about site rules, permits or sign-in
