AHU cleaning in Longwick
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. If you have dust built up on fan impellers and rooms that smell stuffy when the system runs, we can put it right.
Visits to a place like Longwick are fitted around opening hours. The method doesn’t change: inspect first, clean, then record what was done.
A written report with photos follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What AHU cleaning looks like in Longwick
Food Standards Agency records list about 6 hospitals, care homes and childcare premises registered as food businesses across Longwick and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Longwick, about 37 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you. For Longwick, the closest hospital is St John's Hospital, roughly 4.6 miles north. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Wherever a school like Longwick Church of England Combined School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Keep an eye out for any of the following:
- Drain trays holding standing water
- Dirty fans and fan housings
- Coils clogged with dust and debris
- Odours coming through the supply air
St John's Hospital, about 4.6 miles north, is the nearest hospital to Longwick, and healthcare sites of every size need their supply air kept clean.

Different parts, different methods
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
Managing agents and facilities teams in Longwick
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
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 can quote for the whole system.
How it works
There are three stages on the day: 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, and that takes from a few hours for a compact unit to a day or more for a large one. For a site near Longwick, the work is booked around your opening hours, evenings and weekends included.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Let us know when the site is closed or quiet
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Dig out any earlier paperwork for the system
