AHU cleaning in Holloway
Our AHU cleans for sites in Holloway cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers supply and extract fans, filter sections and internal panels, and common reasons people get in touch are condensate trays that won’t empty and dirty fans and fan housings.
For a building in or near Holloway, access is agreed in advance and the visit is planned around the journey.
The paperwork matters as much as the work. You get a written report with photos 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 AHU cleaning looks like in Holloway
Food Standards Agency records list about 9 schools, colleges and universities and about 4 hospitals, care homes and childcare premises registered as food businesses within roughly a mile and a half of the centre of Holloway. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. For Holloway, the closest hospital is St Mark's Hospital, roughly 1.8 miles east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. Holloway is about 30 miles from central London, well within the area we cover across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site.
For schools like Burchetts Green CofE Infants' School, the holidays are the usual time to inspect and clean ventilation.

Part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey, before we quote.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. If you can send pictures, we can arrive in Holloway knowing what to expect.
- We survey the unit from pictures or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Tell us where we can park and unload
- Move anything stored near the system
- Dig out any earlier paperwork for the system
Ask for a quote
Getting a quote does not take long. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Honest limits
Not every problem is solved by AHU cleaning, and we’ll tell you before we start. It doesn’t solve:
- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils
- Problems with the unit’s controls or sensors
If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think before you book.
What the work covers
- Internal panels
- Heating and cooling coils
- Filter sections
- Drain trays
- Supply and extract fans
- Dampers and louvres
Fixed quotes for AHU cleaning in Holloway
We do not publish a price list, because no two systems are the same. The quote depends on:
- Working hours and out-of-hours timing
- What state the system is in
- The scale of the work
- The number of sites or systems
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 drop us a line and we will give you an honest view and a fixed quote.
What we need to know
To help us quote quickly, please include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your last certificate, test record or report
- Photos showing the whole system and its surroundings
- The site address and the type of premises
For AHU cleaning in Holloway, call 0345 646 2711 or send us an email. Tell us what kind of premises it is and when it’s open, and send photos or your last report if you can. A fixed quote typically follows within one working day.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Watch for drips or damp patches near the plant
- Look at the condensate drain whenever the unit is serviced
- File each AHU report in the maintenance log
- Do not ignore odours coming through the grilles
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. They belong in the plant or maintenance log.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Why deal with it now?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. Out of sight is the usual reason a rural system goes too long without attention.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.
Why book with us
- Full insurance on every job
- A written report with photos after each visit
- Evenings, overnight and weekends, plus 24/7 emergency callout
- A fixed price before any work starts

Your questions about AHU cleaning in Holloway
Do you clean school ventilation in Holloway in the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 9 schools, colleges and universities with registered kitchens within about a mile and a half of Holloway. Tell us your holiday dates and we will book the visit for when the site is empty.
Is Holloway within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Holloway included. Photos of the system and directions to the site help us plan the visit.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.
What does TR19 mean?
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.
Is there a survey before the work?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
How long will the unit be out of action?
Cleaning takes one overnight shift for many single units, with bigger plant phased. Large plant can be split over several shifts, so call us on 0345 646 2711 or email us to talk it through.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.
How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Do you need AHU cleaning in Holloway?
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
The symptoms we’re asked about most include:
- Units that have only ever had filter changes
- Condensate trays that won’t empty
- Dust-coated heating and cooling coils
- Stale or musty smells from the ventilation
If you run a surgery, dental practice or care home near Holloway, clean ventilation matters as much to you as to a hospital like St Mark's Hospital (about 1.8 miles east).
