What happens on the day
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes from a few hours for a compact unit to a day or more for a large one. If you can send pictures, we can arrive in Fickleshole knowing what to expect.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Tell us where we can park and unload
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

AHU cleaning in Fickleshole, done properly
We clean air handling units for buildings in Fickleshole and across Surrey, 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 have leaves and litter drawn into the unit and dust-coated heating and cooling coils, we can put it right.
Somewhere as small as Fickleshole, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Different parts, different methods
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Honest limits
It’s worth knowing the limits before booking:
- Coils that are corroded or leaking and need replacing
- Ductwork downstream of the unit, which is a separate clean
- A system that is undersized for the building
If in doubt, phone us on 0345 646 2711 or use the quote form and we will say what we think before you book.

FAQs for Fickleshole
Can you get to a site in Fickleshole?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you clean school ventilation in Fickleshole during the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 4 schools, colleges and universities with registered kitchens within about a mile and a half of Fickleshole. Tell us your holiday dates and we’ll book the visit for when the site is empty.
What does TR19 mean?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Call us any time and explain what’s happened.
Which accreditations do you hold?
Duct Doctor is 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.
How often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
Ventilation in Fickleshole buildings
There are about 4 schools, colleges and universities and about 7 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register within about 1.5 miles of central Fickleshole. Busy, occupied buildings like these are where clean supply air matters most. At about 13 miles from central London, Fickleshole sits well inside the area we cover. Evening, overnight and weekend visits are all possible. Fickleshole’s nearest hospital, Warlingham Park Hospital, is about 1.2 miles south-west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
Healthcare ventilation, from large hospitals like Warlingham Park Hospital (about 1.2 miles south-west) to small clinics, depends on clean filters, coils and ducts.
Fickleshole is about 5 miles north-east of Caterham, in Surrey. Fickleshole gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with photos. Fickleshole is one of 395 places in Surrey we cover for commercial clients. Our London page covers sites nearby (13 miles or so).
Work in CR6 is surveyed, quoted and booked the same way as anywhere else. You’ll find streets such as Featherbed Lane and Fairchildes Lane, all of which we cover for AHU cleaning. If your site is just outside Fickleshole, we cover Farleigh (1 mile west), New Addington (1 mile north), Chelsham (1 mile south-west), Leaves Green (2 miles north-east) and Forestdale (2 miles north-west). Further out, we also cover Epsom (11 miles west), Horley (12 miles south-west), Redhill (9 miles south-west), Ewell (11 miles west), Reigate (10 miles south-west) and Caterham (5 miles south-west).
Around Fickleshole
In Fickleshole, that means kitchens and buildings near Meridian High School, Addington Vale and The White Bear pub, among other places. The nearest railway station is Woldingham station, roughly 3.2 miles south-west of the centre. Nearby you’ll also find Warlingham Park Hospital (1.2 miles south-west). The countryside around Fickleshole includes Nore Hill and Hutchinson's Bank.
Why deal with it now?
Dirt left in an air handling unit does not 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. Our emergency line runs 24/7, but a planned visit to Fickleshole is calmer for everyone.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, ring 0345 646 2711 or drop us a line for straight advice and a fixed quote.

Common problems we fix in Fickleshole
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
These are the problems we see most often:
- Odours coming through the supply air
- Dirty coils holding back the airflow
- Blocked condensate drains and slimy trays
- Air handling units never cleaned inside
Wherever a school like Fairchildes Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Questions to ask before booking
- If the quote is a fixed price or an estimate
- Whether the quote shows VAT
- Whether the quote is based on a survey or photos
- Which accreditations they hold, and whether you can check them
In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
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.
