AHU cleaning in Gosford
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. If you have rooms that smell stuffy when the system runs and intake sections clogged with outdoor debris, we can help.
Somewhere as small as Gosford, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

How the visit works
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. For a village or hamlet like Gosford, tell us about narrow lanes, gates and parking when you book.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down
Get a fixed quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before any work starts.
Advice
Why deal with it now?
If people in a building in Gosford complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. A fault that closes a site in a village like Gosford affects everyone who depends on it.
What you pay depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.

Other services in Gosford
Signs you need AHU cleaning in Gosford
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
Any of these means the system needs a check-up:
- Filters that are clogged or overdue
- Coils clogged with dust and debris
- Units needing a clean before a new tenant or handover
- Stale or musty smells from the ventilation
School buildings such as Edward Feild Primary School are normally done in the holidays, so classrooms aren’t disturbed.

FAQs for Gosford
Can you come to Gosford after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in Gosford keeps running as normal. Just call us on 0345 646 2711, or email photos with your opening times and we will plan around them.
Can a school’s ventilation in Gosford be done out of term time?
Yes, out-of-term visits are normal for schools. Around Gosford, the Food Standards Agency lists about 9 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
What do you need from me for a quote?
A short description and a few pictures plus the address and your hours. We’ll ask for anything else we need.
Will we get paperwork for the AHU clean?
Yes, both a certificate and a report with pictures. It includes a recommended date for the next check.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Part by part
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
What a clean won’t put right
Before you book, it helps to know what’s not included:
- Airflow problems caused by the system’s design
- Breakdowns that need a mechanical engineer
- Coils that are corroded or leaking and need replacing
If you’re not sure, just ring 0345 646 2711 or use the quote form and we will give you a straight answer.
