AHU cleaning for kitchens and businesses in Rotherwick
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. If you have condensate trays that won’t empty and dirty filters cutting the airflow, we can help, from filter sections, supply and extract fans and drain trays onwards.
In a village or hamlet like Rotherwick, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Duct Doctor has been trading since 2009, and we’re 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.

Managing agents and facilities teams in Rotherwick
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
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 pictures, so records stay tidy.

The process
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes from a few hours for a compact unit to a day or more for a large one. If you can send photos, we can arrive in Rotherwick knowing what to expect.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Let us know about parking and loading
- Tell us about site rules, permits or sign-in
- Plan for cooking equipment or plant to be off before we arrive

Keeping the system healthy
Once we have finished, these simple steps help:
- Report water on the plant room floor
- Look at the condensate drain whenever the unit is serviced
- Keep inspection doors on the unit in good order
- Keep the area around the fresh air intake clear
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
What happens if it’s left?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. With notice, the visit to Rotherwick can be fitted around your bookings and events.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.

Signs you need AHU cleaning in Rotherwick
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
If you notice any of these, it’s worth a diagnosis:
- Dust-coated heating and cooling coils
- Debris and leaves in the fresh air intake
- Odours coming through the supply air
- Fan sections that haven’t been cleaned in years
Hospitals such as Fleet Community Hospital (about 5.5 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Rotherwick are no different.
Before booking anyone
- If they look at the system before pricing
- Whether the whole system is included, or only the parts that are easy to reach
- Whether VAT is included
- If the quote is a fixed price or an estimate
How the job changes from site to site
Internal casing and panels
We open each section through its doors and close them securely when we are done before the unit is handed back.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
