AHU cleaning in Enfield Wash
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from photos or a site visit, and give you a fixed quote before any cleaning starts. Common call-outs are for leaves and litter drawn into the unit and dust-coated heating and cooling coils, across drain trays, supply and extract fans and internal panels.
For a building near Enfield Wash, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Around Enfield Wash, a kitchen or building out of action is missed straight away.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.

Enfield Wash questions
Can a school’s ventilation in Enfield Wash be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. There are about 45 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Enfield Wash. Just phone us on 0345 646 2711 or send us an email with your term dates and we will plan around them.
Can you come to Enfield Wash after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. When you ring 0345 646 2711, or email photos, mention when the site is quiet.
How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
When should our AHU next be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
What information do you need?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. A site near Enfield Wash normally has room to park, so the questions are about access to the system and your hours.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Before we arrive
- Arrange a key holder or contact on site
- Plan for cooking equipment or plant to be off before we arrive
- Mention any sign-in, permit or induction we need

Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across Hertfordshire. Work can be phased by floor, building or site around the people who use them.
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Do you need AHU cleaning in Enfield Wash?
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Keep an eye out for these warning signs:
- Leaves and litter drawn into the unit
- Stale or musty smells from the ventilation
- Dirty filters cutting the airflow
- Plant that needs cleaning after a refit
If you manage offices or shops near Turkey Street station, their ventilation can be inspected and cleaned out of hours.
