AHU Cleaning in Coneyhurst
Air handling unit cleaning in Coneyhurst, surveyed first and signed off with a written report and pictures. Ask us for a fixed quote.
- Dust-coated heating and cooling coils
- Dirty filters cutting the airflow
- Units needing a clean before a new tenant or handover
Between visits
Here’s the after-treatment advice, in brief:
- Keep the certificate and photo report with the plant records
- Look at the condensate drain whenever the unit is serviced
- Keep filter changes on time and recorded
- Watch for drips or damp patches near the plant
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.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
How we handle AHU cleaning in Coneyhurst
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. The work covers drain trays, heating and cooling coils and supply and extract fans, and common reasons people get in touch are condensate trays that won’t empty and coils clogged with dust and debris.
Work in a small place like Coneyhurst starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What we are called out for in Coneyhurst
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.
Keep an eye out for any of the following:
- Odours coming through the supply air
- Units needing a clean before a new tenant or handover
- Filters that are clogged or overdue
- Air handling units never cleaned inside
Classrooms and halls at schools such as The Weald School are easiest to work in when pupils are away.

Your questions about AHU cleaning in Coneyhurst
Is Coneyhurst in your area for AHU cleaning?
Yes, Coneyhurst is covered. To start, ring 0345 646 2711, or email photos with a few photos of the system.
Do you work at weekends in Coneyhurst?
Yes. We work evenings, overnight and at weekends. It means the site in Coneyhurst keeps running as normal. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
Will the ventilation be off while you clean?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
What about areas you cannot get to?
Anything we cannot reach goes on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
What information do you need?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
How long will the unit be out of action?
Typically the clean takes anything from half a day for one small unit to several shifts for a plant room full of them. The shutdown is planned to fit, out of hours if needed.

What else we do in Coneyhurst
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Why it’s worth doing now in Coneyhurst
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 Coneyhurst simpler. In a small place like Coneyhurst, a system that fails can take a site out of use.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.

- Evenings, overnight and weekends, plus 24/7 emergency callout

How we price AHU cleaning
Before we fix a price, we need to know a few things. We check:
- Whether it’s a one-off visit or part of a schedule
- Site requirements such as sign-in and permits
- Travel, parking and unloading
- What state the system is in
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

- How we’d reach plant on a roof or in a plant room

Part by part
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
How it works
We work around your opening hours, not the other way round. 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 a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere as small as Coneyhurst, the date and timings are agreed with you well before the day.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Clear the space around the work
- Arrange a key holder or contact on site
- Dig out any earlier paperwork for the system
