How the visit works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. If the van will struggle with a lane or gateway near Ardley End, let us know and we will plan around it.
- 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.
Before we arrive
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in

AHU cleaning for kitchens and businesses in Ardley End
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. The work covers internal panels, filter sections and dampers and louvres, and people most often call us about plant that needs cleaning after a refit and air handling units with blocked filters.
Somewhere as small as Ardley End, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Places near Ardley End
What else we do in Ardley End
For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Honest limits
It’s worth knowing the limits before booking:
- The supply and extract ducts, quoted separately
- Leaking heating or cooling coils
- Building management system faults
If you’re not sure, just give us a ring on 0345 646 2711 or use the quote form and we will give you a straight answer.

Signs you need AHU cleaning in Ardley End

Keep an eye out for any of the following:
- Dust built up on fan impellers
- Leaves and litter drawn into the unit
- Air handling units with blocked filters
- Units needing a clean before a new tenant or handover
School buildings such as Hatfield Heath Primary School are usually done in the holidays, so classrooms are not disturbed.
What to look for in a quote
- Whether the quote is based on a survey or photos
- Whether the price is fixed
- Whether the quote shows VAT
- What happens if part of the system can’t be accessed
What affects the quote in Ardley End
You will get a fixed price before we start. It’s based on:
- Where the site is and how we reach it
- What state the system is in
- Whether we need access equipment or extra panels
- Any permits to work or inductions
Leaving it longer rarely makes the work cheaper. 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 us on 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- Close-ups of filters, grilles, hatches or access panels
- Your opening hours and when the area is out of use
- Your last certificate, test record or report
- Any symptoms, from odd noises to smells or leaks
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.
Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Store the TR19 paperwork where auditors can find it
- Look at the condensate drain whenever the unit is serviced
- Don’t ignore odours coming through the grilles
- Report stiff or damaged access doors
When we have closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
