AHU cleaning in Whitchurch Hill
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. The work covers internal panels, heating and cooling coils and filter sections, and people most often call us about dust-coated heating and cooling coils and debris and leaves in the fresh air intake.
For a building in or near Whitchurch Hill, access is agreed in advance and the visit is planned around the journey.
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 are fully insured.

Aftercare tips
So the system stays in good health:
- Clear leaves and litter away from the intake
- Report water on the plant room floor
- Keep the certificate and photo report with the plant records
- Flag stale or damp smells in the supply air
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Managing agents and facilities teams in Whitchurch Hill
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. For a village or hamlet like Whitchurch Hill, tell us about narrow lanes, gates and parking when you book.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- 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.
Getting ready for the visit
- Let us know about parking and loading
- Find the previous report, if there is one
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
