AHU cleaning for kitchens and businesses in Coleman's Hatch
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. If you’re dealing with drain trays holding standing water and fan sections that haven’t been cleaned in years, we can put it right, from dampers and louvres, drain trays 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, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

How the visit works
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Seeing the system in pictures first means the trip to Coleman's Hatch can be planned properly.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Let us know when the site is closed or quiet
- Move anything stored near the system
Ask for a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Common questions in Coleman's Hatch
Can you work in Coleman's Hatch outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in Coleman's Hatch can fit around your hours. Tell us your opening hours when you ask for a quote.
Can a school’s ventilation in Coleman's Hatch be done out of term time?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Coleman's Hatch. You can phone us on 0345 646 2711, or email photos with the dates the site is empty.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and the report recommends a next date.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and leave the area clean.

What else we do in Coleman's Hatch
Looking after it afterwards
Once we have finished, these simple steps help:
- Keep the certificate and photo report with the plant records
- Diary the inspection date recommended in the report
- Make sure the unit’s access doors open easily
- Keep the area around the fresh air intake clear
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
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 Coleman's Hatch
Sites vary more than people expect. The main factors:
- A single visit or a regular plan
- Where the site is and how we reach it
- Working hours and out-of-hours timing
- Access, including roofs, risers and ceiling voids
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 give you a fixed price before work begins.
Asking for a quote
When you call or email, it’s useful to have:
- The times we could work without disrupting the site

When to call us in Coleman's Hatch
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
What we’re most often called out for:
- Condensate trays that won’t empty
- Filters that are clogged or overdue
- Stale or musty smells from the ventilation
- Leaves and litter drawn into the unit
Healthcare buildings such as Queen Victoria Hospital, about 4.4 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Coleman's Hatch, yours matters too.
