AHU cleaning for kitchens and businesses in Nash Street
Where a building in Nash Street has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. Typical jobs include plant that has been serviced but not cleaned and stale or musty smells from the ventilation, on drain trays, filter sections and supply and extract fans.
Somewhere as small as Nash Street, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
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.

Why deal with it now?
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. It also means the next inspection has less to find. Equipment tucked in a roof space or outbuilding near Nash Street rarely gets looked at unless someone books it.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

What we’re called out for in Nash Street
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.
What we’re most often called out for:
- Debris and leaves in the fresh air intake
- Dirty fans and fan housings
- Air handling units never cleaned inside
- Units needing a clean before a new tenant or handover
Classrooms and halls at schools such as Chiddingly Primary School are easiest to work in when pupils are away.
Questions to ask before you book
- What’s included in the scope, part by part
- Whether VAT is included
- Whether the figure could change on the day
- When they can work, and whether that’s outside your opening hours
Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Part by part
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
When it’s something else
We won’t sell you work that does not address the problem, so here are the limits:
- Building management system faults
- Damaged coils beyond cleaning
- Breakdowns that need a mechanical engineer
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we will tell you honestly.

Between visits
After the visit, a few habits help the work last:
- Report water on the plant room floor
- Check the drain tray is emptying during routine visits
- Store the TR19 paperwork where auditors can find it
- Keep filter changes on time and recorded
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
