AHU cleaning for kitchens and businesses in Hayes
We clean air handling units for buildings in Hayes and across Greater London, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you are dealing with dirty fans and fan housings and air handling units due a clean after building work, we can help, from drain trays, internal panels and supply and extract fans onwards.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Hayes is normally planned out of hours. Parking and loading are agreed with the building in advance.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
What the work involves, part by part
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.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Questions from Hayes
Do you clean school ventilation in Hayes in the holidays?
Yes. The holidays are the usual time for school work. Around Hayes, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can parking be tricky for a job in Hayes?
London parking can be tight, so details of loading bays and permits help. Working overnight, as we often do in London, usually makes it simpler.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Do you clean the ductwork as well?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and the report recommends a next date.

Honest limits
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Ventilation that was badly designed in the first place
- Mechanical faults with motors, belts or bearings
- Leaking heating or cooling coils
If in doubt, phone us on 0345 646 2711, or email photos and we will say what we think.
Where we work
- Heating and cooling coils
- Dampers and louvres
- Internal panels
- Supply and extract fans
- Drain trays
- Filter sections
What happens on the day
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes from a few hours for a compact unit to a day or more for a large one. If your building in Hayes has sign-in rules, permits or key holders, mention them when you book.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Mention any parking or loading restrictions
- Let us know when the site is closed or quiet

Advice
What we’re called out for in Hayes
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Hayes, that’s air they breathe for hours at a time.
Look out for these warning signs:
- Dirty filters cutting the airflow
- Dust-coated heating and cooling coils
- Units that have only ever had filter changes
- Condensate trays that will not empty
For schools like Hawes Down Primary School, the holidays are the usual time to inspect and clean ventilation.

Managing agents and facilities teams in Hayes
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Watch for drips or damp patches near the plant
- Check the drain tray is emptying during routine visits
- Do not store bins or materials near the intake
- Do not ignore odours coming through the grilles
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
