How the visit works
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes half a day to a full day per unit, with large plant planned over several shifts. We agree a date with you, plan the drive to Wormshill and turn up when the site is quiet.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Let us know about permits to work or site inductions
- Find the previous report, if there is one
- Arrange a key holder or contact on site

About our AHU cleaning in Wormshill
We clean air handling units for buildings in Wormshill and across Kent, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers dampers and louvres, supply and extract fans and internal panels, and common reasons people get in touch are blocked condensate drains and slimy trays and intake sections clogged with outdoor debris.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
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.

Different parts, different methods
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.

What else we do in Wormshill
What affects the cost of AHU cleaning
There’s no set price list, because no two systems are the same. The quote depends on:
- How big the system is
- When the work can happen, such as evenings, overnight or weekends
- Parking and loading at the site
- Access, including roofs, risers and ceiling voids
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- When the site is open and when it’s quiet
- Any symptoms, from odd noises to smells or leaks
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room

Do you need AHU cleaning in Wormshill?
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
What we are most often called out for:
- Dirty coils holding back the airflow
- Filters that are clogged or overdue
- Plant that needs cleaning after a refit
- Fan sections that haven’t been cleaned in years
In Wormshill, we look inside the system before deciding what needs cleaning.

FAQs for Wormshill
Do you work overnight in Wormshill?
Yes, we can come after you close and finish before you open. That way a site in Wormshill doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Do you cover Wormshill for AHU cleaning?
Yes, we work in Wormshill and the places around it. To start, phone us on 0345 646 2711 or send us an email with a few pictures of the system.
Do you offer emergency callouts?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
How much does AHU cleaning cost in Wormshill?
Every site is different, so each gets its own fixed quote. To get one, call 0345 646 2711, or email photos with the site type, opening hours and a few pictures.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with photos where it helps.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
How often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Why deal with it now?
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Rural sites can’t always move to another kitchen or room when something fails.
The cost depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning will not do:

- Faulty motors, drives or bearings
- Ventilation that was badly designed in the first place
