Look out for any of the following:
- Dirty coils holding back the airflow
- Intake sections clogged with outdoor debris
- Plant that has been serviced but not cleaned
- Fan sections that haven’t been cleaned in years
For workplaces around Slough station with mechanical ventilation, cleaning can be done in the evening or at weekends.
What to look for in a quote

How we handle AHU cleaning in Chalvey
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you have dirty fans and fan housings and units needing a clean before a new tenant or handover, we can help.
In a smaller place like Chalvey, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Why act early in Chalvey
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Around Chalvey, a kitchen or building out of action is missed right away.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

What we do, step by step
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. In a smaller place like Chalvey, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Mention any parking or loading restrictions
- Plan for cooking equipment or plant to be off before we arrive
- Agree a time when the area can be out of use

Honest limits
We will not sell you work that does not address the problem, so here are the limits:
- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils
- Problems with the unit’s controls or sensors

What we work on in Chalvey
- Supply and extract fans
- Dampers and louvres
- Filter sections

Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Chalvey questions
Can you clean school ventilation in Chalvey during the holidays?
Yes, out-of-term visits are normal for schools. There are about 45 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Chalvey. You can call us on 0345 646 2711, or email photos with the dates the site is empty.
Is Chalvey within the area you cover?
Yes, we work in villages as well as towns, and Chalvey is covered. Just mention lanes, gates or anything else about the site when you book.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We’ll tell you after the survey whether the ducts need it.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
What should I send you?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply ring 0345 646 2711 or use the quote form.
How long does an AHU clean take?
Cleaning takes one overnight shift for many single units, with bigger plant phased. Bigger units can be phased, and you can call 0345 646 2711 or send us an email to plan it.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
Landlords, agents and facilities managers
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Between visits
How long the results last depends on use and care. We suggest:
- Change filters on schedule and log each change
- Do not store bins or materials near the intake
- Report water on the plant room floor
- Diary the inspection date recommended in the report
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
