AHU cleaning in Copythorne, done properly
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. If you’re dealing with dust-coated heating and cooling coils and units that have only ever had filter changes, we can put it right, from drain trays, heating and cooling coils and internal panels onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces 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 are fully insured.

Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Do you need AHU cleaning in Copythorne?
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
What we’re most often called out for:
- Blocked condensate drains and slimy trays
- Fan sections that haven’t been cleaned in years
- Units that have only ever had filter changes
- Filters that are clogged or overdue
If you manage a school such as Copythorne CofE Infant School, ventilation cleaning is best booked for the holidays.
Before you book anyone

- Whether VAT is included
- Whether the figure could change on the day
- What happens if part of the system can’t be accessed
Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Make sure the unit’s access doors open easily
- Keep the certificate and photo report with the plant records
- Don’t ignore odours coming through the grilles
- Diary the inspection date recommended in the report
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
What the work involves, part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so repairs can be planned.
What happens on the day
Each visit runs to the same pattern: sheeting and protection first, make the system safe, carry out the AHU cleaning, clear away and leave you the report. The visit itself takes from a few hours for a compact unit to a day or more for a large one. Somewhere as small as Copythorne, the date and timings are agreed with you well before the day.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Make sure someone can let us in and lock up afterwards
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
We do not publish a price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, give us a ring on 0345 646 2711 or send us an email.

Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Tatchbury Mount Hospital is the nearest hospital, about 1.3 miles east of Copythorne.
