AHU cleaning for kitchens and businesses in Ashlett
Our AHU cleans for sites in Ashlett cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. If you’re dealing with units that have only ever had filter changes and dust-coated heating and cooling coils, we can help.
For a building in or near Ashlett, 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 pictures follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Common problems we fix in Ashlett
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Look out for any of the following:
- Debris and leaves in the fresh air intake
- Odours coming through the supply air
- Air handling units due a clean after building work
- Coils clogged with dust and debris
Healthcare buildings such as Coldeast, about 4 miles north-east, depend on their ventilation; if you manage a surgery, clinic or care home near Ashlett, yours matters too.
Before booking anyone
- When they can work, and whether that’s outside your opening hours
- How VAT is shown on the quote
- Whether the figure could change on the day
- What happens if part of the system can’t be accessed
Part by part
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey so the quote reflects it.
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
What happens on the day
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes from a few hours for a compact unit to a day or more for a large one. A few photos of the system help us make the most of a visit to a place like Ashlett.
- First we agree when the unit can be switched off, including evenings or weekends.
- 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.
- After photos are taken and the certificate issued.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

What affects the quote in Ashlett
You’ll 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
- How easy every part is to reach
- One-off work versus a regular cycle
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, call 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.
What to send for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
We do not publish a price list, because every site is different. We look at your system first, from photos or on a visit, and then give you a fixed quote. To start, phone us on 0345 646 2711, or send details by email.
What AHU cleaning looks like in Ashlett
There are about 3 care, childcare and hospital premises on the FSA’s food hygiene register within about 1.5 miles of central Ashlett. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Ashlett’s nearest hospital, Coldeast, is about 4 miles north-east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Wherever a school like Fawley Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.

FAQs for Ashlett
Do you cover Ashlett for AHU cleaning?
Yes, Ashlett is covered. Just phone us on 0345 646 2711 or email us with a few details of the site.
Can you get to a site in Ashlett?
Yes. Ashlett is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What should I send you?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
How much does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we will normally reply within one working day.
How often should an air handling unit 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.
How long does an AHU clean take?
Cleaning takes anything from half a day for one small unit to several shifts for a plant room full of them. Bigger units can be phased, so call 0345 646 2711, or email photos to talk it through.
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Look at the condensate drain whenever the unit is serviced
- File each AHU report in the maintenance log
- Keep inspection doors on the unit in good order
- Stick to the filter change plan
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
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.
