AHU cleaning for kitchens and businesses in Wilmington
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you’re dealing with dirty coils holding back the airflow and air handling units due a clean after building work, we can help.
Work in a small place like Wilmington starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

When to call us in Wilmington
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
What we are most often called out for:
- Rooms that smell stuffy when the system runs
- Dirty coils holding back the airflow
- Debris and leaves in the fresh air intake
- Plant that needs cleaning after a refit
Eastbourne District General Hospital, about 4 miles south-east, is the nearest hospital to Wilmington, and healthcare sites of every size need their supply air kept clean.
What your quote should include
- Exactly which parts of the system are covered
- Whether VAT is included
- Whether inaccessible sections are listed on the report
- When they can work, and whether that is outside your opening hours
Why deal with it now?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. That makes the next inspection of a building in Wilmington simpler. In a small place like Wilmington, a system that fails can take a site out of use.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Why us?
- Photo reports with every job
- Trading since 2009
- We diagnose before we treat
- Fully insured
Questions from Wilmington
Can the work in Wilmington be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. When you call 0345 646 2711 or send us an email, mention when the site is quiet.
Do you cover smaller places like Wilmington?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Are you fully insured?
Yes. We carry full insurance and have been trading since 2009.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.
Aftercare tips
A little care between visits keeps the system in better shape. We recommend:
- Do not store bins or materials near the intake
- Change filters on schedule and log each change
- Report musty smells from the vents right away
- Make sure condensate is draining away
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Fixed quotes for AHU cleaning in Wilmington
We quote each job individually. This is what makes a difference:
- The size of the system
- One-off work versus a regular cycle
- Whether we need access equipment or extra panels
- The condition of the system
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before we start.
What we need to know
You don’t need the technical terms. Just send:
- Your last certificate, test record or report
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
To help us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Then give us a ring on 0345 646 2711 or email us.
Multi-site and managed buildings
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.

When it’s something else

Where we work
- Drain trays
- Dampers and louvres
- Filter sections
- Supply and extract fans
- Internal panels
- Heating and cooling coils
How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job 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 Wilmington.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Name a contact who can let us in at the agreed time
- Tell us where we can park and unload
