How we handle AHU cleaning in Maidenhead
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers heating and cooling coils, filter sections and dampers and louvres, and the jobs we see most are dust built up on fan impellers and intake sections clogged with outdoor debris.
Many schools and offices in a town like Maidenhead have a mix of older and newer ventilation. An inspection shows which parts need cleaning.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
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 grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Maidenhead: your questions answered
Do you clean school ventilation in Maidenhead in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 45 schools, colleges and universities with registered kitchens within about a mile and a half of Maidenhead. Just ring 0345 646 2711 or email us with your term dates and we’ll plan around them.
Is AHU cleaning available in Maidenhead?
Yes, Maidenhead is within the area we cover across London and the South East. You can call us on 0345 646 2711 or send us an email and let us know what needs doing.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
What happens if you can’t reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after pictures. Keep them in the maintenance log.
How long will the unit be out of action?
As a guide, it takes one overnight shift for many single units, with bigger plant phased. We plan the shutdown around that, including evenings or weekends.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
Is there a survey before the work?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.

- One-off work versus a regular cycle

- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business

Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price, before any work starts.

- The supply and extract ducts, quoted separately

Parts of the system we cover
- Dampers and louvres
- Drain trays
- Internal panels
- Heating and cooling coils
- Supply and extract fans
- Filter sections
Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Stick to the filter change plan
- Make sure condensate is draining away
- Report water on the plant room floor
- Do not ignore odours coming through the grilles
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
