What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes one overnight shift for many single units, with bigger plant phased. If the van will struggle with a lane or gateway near Lumley, let us know and we’ll plan around it.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Let us know about permits to work or site inductions
- Arrange a key holder or contact on site
- Agree a time when the area can be out of use
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. Add the site type and your opening hours, and many jobs can be priced from that alone.
Advice
AHU cleaning in Lumley
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you are dealing with dust built up on fan impellers and intake sections clogged with outdoor debris, we can put it right, from heating and cooling coils, filter sections and drain trays onwards.
In a village or hamlet like Lumley, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Why deal with it now?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. It’s worth booking a check, because nobody sees inside a duct day to day.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
Why choose Duct Doctor in Lumley
- We’re fully insured
- Survey first, then a fixed quote
- CHAS and SafeContractor accredited, with ISO 9001

How we price AHU cleaning
We quote each job individually. These are the things that affect it:
- Where the site is and how we reach it
- A single visit or a regular plan
- How easy every part is to reach
- How big the system is
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
Asking for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Any previous report or certificate
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
To get a fixed quote, give us a ring on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
Ventilation in Lumley buildings
Going by the FSA’s register, there are about 6 schools, colleges and universities, about 17 caring premises (care homes, nurseries and hospitals) and about 5 hotels, B&Bs and guest houses serving food within 1.5 miles or so of the middle of Lumley. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. For Lumley, the closest hospital is Havant War Memorial Hospital, roughly 2.4 miles west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. At about 58 miles from central London, Lumley sits well inside the area we cover. Visits are booked around your hours, evenings and weekends included.
Classrooms and halls at schools such as St James Church of England Controlled Primary School are easiest to work in when pupils are away. If you run a surgery, dental practice or care home near Lumley, clean ventilation matters as much to you as to a hospital like Havant War Memorial Hospital (about 2.4 miles west). If you run an office near Emsworth station, its supply ductwork can gather dust for years before anyone looks inside.
Lumley is about 1 mile east of Emsworth, in West Sussex. We provide AHU cleaning for businesses, landlords and public buildings in Lumley and the rest of West Sussex. Across West Sussex, we cover 371 places, Lumley among them. Portsmouth is in our area too, about 7 miles from Lumley.
Work in PO10 follows the same survey, fixed quote and written report as everywhere else we cover. Whether your site is on Lumley Road and Northlands Park or anywhere close by, we can help. Close by, we work in Emsworth (1 mile west), Westbourne (1 mile north), Southbourne (1 mile east), Woodmancote (1 mile north-east) and Denvilles (1 mile west). Within a short drive, we also cover Bognor Regis (12 miles east), Chichester (7 miles east), Selsey (10 miles south-east), Portfield (7 miles east), Yapton (14 miles east) and East Wittering (7 miles south-east).
Near you in Lumley
Typical jobs here are in premises near Eames Farm, Bourne Community College and Lord Raglan P.H. Pub and the streets around them. There’s a railway station in Lumley itself: Emsworth station. A little further out are Warblington Castle (1.6 miles west) and Emsworth Museum (within half a mile south-west). Green spaces nearby include Stoke Down and Brook Meadow (Emsworth).
What the work involves, part by part
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Drain trays
Older trays can corrode and start leaking. We record their condition with photos so repairs can be planned.
Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Clear leaves and litter away from the intake
- Plan the next inspection before the last report gets filed away
- Report stiff or damaged access doors
- Change filters on schedule and log each change
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Landlords, agents and facilities managers
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
