About our AHU cleaning in Postling Green
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. If you’re dealing with units needing a clean before a new tenant or handover and dirty coils holding back the airflow, we can help.
In a village or hamlet like Postling Green, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

How it works
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes a single shift for a typical unit, longer for large or heavily soiled ones, and the area is cleaned down before we leave. The timing of a visit to Postling Green is set by you, and the travel is our side of the planning.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
How to prepare
- Move anything stored near the system
- Arrange a key holder or contact on site
- Mention any locked doors, roof access or ceiling voids

Advice
Why it’s worth doing now in Postling Green
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. It’s worth booking a check, because nobody sees inside a duct day to day.
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 choose Duct Doctor in Postling Green
- Out-of-hours work and a 24/7 emergency line
- Fixed quotes from a survey or photos
- We’re fully insured
- A written report with photos after each visit

Your questions about AHU cleaning in Postling Green
Do you cover Postling Green for AHU cleaning?
Yes. We work across London and the South East, and Postling Green is part of that. Just give us a ring on 0345 646 2711, or email photos with a few details of the site.
Do you cover smaller places like Postling Green?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
What if parts of the system cannot be reached?
Anything we can’t reach goes on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
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.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, give us a ring on 0345 646 2711 or use the quote form and tell us about the site and its opening hours.
Do you look at the system first?
Yes. Photos often do the job, and larger or hidden systems get a visit.
What affects the quote in Postling Green
Your quote is based on your site. We consider:
- The number of sites or systems
- Whether we need access equipment or extra panels
- When the work can happen, such as evenings, overnight or weekends
- The scale of the work
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and why the quote is fixed before we start.
What we need to know
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
- Photos showing the whole system and its surroundings
To help us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Then give us a ring on 0345 646 2711, or send details by email.
What the work involves, part by part
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Internal casing and panels
We open each section through its doors and close them securely when we are done before the unit is handed back.
Managing agents and facilities teams in Postling Green
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
We also work for facilities teams across offices, schools and healthcare across Kent. Larger estates can be phased building by building around the people who use them.
What we are called out for in Postling Green
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
The symptoms we’re asked about most are:
- Drain trays holding standing water
- Stale or musty smells from the ventilation
- Dirty fans and fan housings
- Plant that needs cleaning after a refit
Hospitals such as William Harvey Hospital (about 4.6 miles north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Postling Green are no different.
