AHU cleaning in Chislet, done properly
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. The work covers internal panels, heating and cooling coils and dampers and louvres, and the jobs we see most are filters that are clogged or overdue and leaves and litter drawn into the unit.
In a village or hamlet like Chislet, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The paperwork matters as much as the work. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What else we do in Chislet
Your questions about AHU cleaning in Chislet
Is Chislet in your area for AHU cleaning?
Yes. Our area runs across London and the South East, Chislet included. You can call 0345 646 2711 or drop us a line and tell us what needs doing.
Is Chislet within the area you cover?
Yes, we work in villages as well as towns, and Chislet is covered. Just mention lanes, gates or anything else about the site when you book.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
How long does it take to clean an air handling unit?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Keep the area around the fresh air intake clear
- Note any water around the unit or leaks below it
- Store the TR19 paperwork where auditors can find it
- Report musty smells from the vents right away
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes one overnight shift for many single units, with bigger plant phased. If you can send pictures, we can arrive in Chislet knowing what to expect.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- 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.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Move anything stored near the system
- Let us know about parking and loading

What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Planning a trip to Chislet ahead is easier for everyone than a rushed one.
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 unsure, call us on 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.

Staff cleaning versus specialist work
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.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
When it’s something else
Some problems need a different service or another trade:
- Ductwork downstream of the unit, which is a separate clean
- Mechanical faults with motors, belts or bearings
- Building management system faults

Where we work
- Filter sections
- Internal panels
- Heating and cooling coils
- Supply and extract fans
- Dampers and louvres
- Drain trays
Do you need AHU cleaning in Chislet?
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
Clients typically contact us after spotting something like this:
- Filters that are clogged or overdue
- Fan sections that haven’t been cleaned in years
- Units that have only ever had filter changes
- Drain trays holding standing water
Classrooms and halls at schools such as Chislet Church of England Primary School are easiest to work in when pupils are away.
