Common questions in Chilton
Do you work in villages like Chilton?
Yes, we work in villages as well as towns, and Chilton is covered. The journey is planned ahead, so a few details about the route help.
Do you work overnight in Chilton?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and clean down when we finish.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
How we handle AHU cleaning in Chilton
If the units serving a building in Chilton have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. If you have air handling units never cleaned inside and blocked condensate drains and slimy trays, we can put it right.
For a building in or near Chilton, access is agreed in advance and the visit is planned around the journey.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Why deal with it now?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. Rural sites can’t always move to another kitchen or room when something fails.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.

Different parts, different methods
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
When it’s something else
It’s worth knowing the limits before booking:
- Controls and BMS settings that run the unit
- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils
If in doubt, give us a ring on 0345 646 2711 or email us and we will say what we think.

Common problems we fix in Chilton
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and that is where slime and odours start.
Keep an eye out for any of the following:
- Intake sections clogged with outdoor debris
- Dirty coils holding back the airflow
- Drain trays holding standing water
- Units needing a clean before a new tenant or handover
Wherever a school like Chilton County Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Staff cleaning versus specialist work
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 do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
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 anything from half a day for one small unit to several shifts for a plant room full of them. Rural roads and tight entrances are worth telling us about before a visit to Chilton.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Mention any locked doors, roof access or ceiling voids
- Make sure equipment near the work can be switched off and left to cool
- Find the previous report, if there is one

Advice
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Keep inspection doors on the unit in good order
- Check the drain tray is emptying during routine visits
- Stick to the filter change plan
- Don’t store bins or materials near the intake
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
