AHU cleaning for kitchens and businesses in Cuffley
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. The work covers filter sections, internal panels and heating and cooling coils, and the jobs we see most are air handling units never cleaned inside and dust-coated heating and cooling coils.
Smaller buildings around Cuffley often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Looking after it afterwards
A little care between visits keeps the system in better shape. Our advice:
- Book the next check in line with the report
- Stick to the filter change plan
- Note any water around the unit or leaks below it
- Do not store bins or materials near the intake
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
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.
Honest limits
Before you book, it helps to know what’s not included:

A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before work begins.

What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes one overnight shift for many single units, with bigger plant phased. Everything the job in Cuffley needs is worked out beforehand, from the survey.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Clear the space around the work
- Mention any sign-in, permit or induction we need
- Name a contact who can let us in at the agreed time
Getting a quote
Getting a quote doesn’t take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Questions from Cuffley
Can the work in Cuffley be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Cuffley needn’t be disturbed. Your opening times are the first thing we ask for.
Do you do school ventilation cleaning in Cuffley in the summer holidays?
Yes. The holidays are the usual time for school work. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Cuffley, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
Will the ventilation be off while you clean?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
How long does it take to clean an air handling unit?
Typically the clean takes one overnight shift for many single units, with bigger plant phased. We plan the shutdown around that, out of hours if needed.
Landlords, agents and facilities managers
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
