AHU cleaning for kitchens and businesses in Fetcham
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. If you have air handling units with blocked filters and units needing a clean before a new tenant or handover, we can help, from dampers and louvres, drain trays and heating and cooling coils onwards.
Around a place like Fetcham, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Fixed quotes for AHU cleaning in Fetcham
We don’t publish a price list, because sites vary so much. The quote depends on:
- How big the system is
- Whether we need access equipment or extra panels
- Site rules, permits and inductions
- The number of sites or systems
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- The site address and the type of premises
- When the site is open and when it’s quiet
- Any symptoms, from odd noises to smells or leaks
- Photos showing the whole system and its surroundings
Getting a quote does not take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. 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. Reaching it takes a specialist with the right equipment.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of 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.
Your questions about AHU cleaning in Fetcham
Do you do school ventilation cleaning in Fetcham in the summer holidays?
Yes, out-of-term visits are normal for schools. There are about 7 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Fetcham. Just call 0345 646 2711, or send details by email with your term dates and we will plan around them.
Do you work at weekends in Fetcham?
Yes, out-of-hours work is a big part of what we do. It means the site in Fetcham keeps running as normal. Let us know the hours you’re closed and we will book within them.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
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.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where necessary.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.
Do you look at the system first?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
Do you need AHU cleaning in Fetcham?
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
Look out for these warning signs:
- Drain trays holding standing water
- Leaves and litter drawn into the unit
- Dust-coated heating and cooling coils
- Air handling units due a clean after building work
Healthcare buildings such as Headley Court, about 3.4 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Fetcham, yours matters too.
Before you book anyone
- Exactly which parts of the system are covered
- Whether the work can be done while the site is closed
- Whether the quote shows VAT
- What records you will receive afterwards
When it’s something else
Some problems need a different service or another trade:
- Breakdowns that need a mechanical engineer
- Airflow problems caused by the system’s design
- Damaged coils beyond cleaning
Not sure which it is? You can ring 0345 646 2711 or email us and we will tell you honestly.
What the work covers
- Internal panels
- Filter sections
- Heating and cooling coils
- Supply and extract fans
- Drain trays
- Dampers and louvres
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes anything from half a day for one small unit to several shifts for a plant room full of them. Because the survey comes first, a visit to Fetcham can usually be finished without a second trip.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Arrange a key holder or contact on site
- Tell us where we can park and unload
- Dig out any earlier paperwork for the system
Getting a quote
For a fixed quote, call us on 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
