AHU cleaning in Swaile's Green, done properly
Our AHU cleans for sites in Swaile's Green cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. Common call-outs are for debris and leaves in the fresh air intake and coils clogged with dust and debris, across supply and extract fans, internal panels and dampers and louvres.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Landlords, agents and facilities managers
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’re happy to quote for all of it.
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
What we do, step by step
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Rural roads and tight entrances are worth telling us about before a visit to Swaile's Green.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive
- Name a contact who can let us in at the agreed time
- Tell us the best time to work, such as after service or at a weekend
- Dig out any earlier paperwork for the system
Getting a quote
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, call us on 0345 646 2711 or email us.

Aftercare tips
To keep the system working properly between visits:
- Flag stale or damp smells in the supply air
- Keep inspection doors on the unit in good order
- Report water on the plant room floor
- Do not store bins or materials near the intake
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
Honest limits
Before you book, it helps to know what’s not included:
- Damaged coils beyond cleaning
- Ventilation that was badly designed in the first place
- Faulty motors, drives or bearings
Not sure which it is? You can ring 0345 646 2711 or drop us a line and we’ll tell you honestly.
Parts of the system we cover
- Internal panels

Drain trays
