- Debris and leaves in the fresh air intake
- Drain trays holding standing water
- Air handling units due a clean after building work
What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Pictures of the system and its access let us plan the work in Petteridge before we set off.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Mention any parking or loading restrictions
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any sign-in, permit or induction we need
How to get a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

AHU cleaning in Petteridge, done properly
Our AHU cleaning covers sites in Petteridge and the rest of Kent, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you are dealing with leaves and litter drawn into the unit and dirty coils holding back the airflow, we can help, from supply and extract fans, dampers and louvres and internal panels onwards.
In a village or hamlet like Petteridge, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Nothing is signed off by word of mouth: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Signs you need AHU cleaning in Petteridge
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that’s where slime and odours start.
Most sites get in touch when they notice something like this:
- Dust built up on fan impellers
- Drain trays holding standing water
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
Healthcare buildings such as Tunbridge Wells Hospital, about 3.2 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Petteridge, yours matters too.
Questions to ask before you book
- When the next visit should be, and why
- Exactly which parts of the system are covered
- Whether they’re fully insured
- Whether a survey comes first
Why it’s worth doing now in Petteridge
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. In a small place like Petteridge, a system that fails can take a site out of use.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before we start.
Why choose Duct Doctor in Petteridge
- Every visit written up, with photos
- Out-of-hours work and a 24/7 emergency line
- One number for every site across the South East and London
- Full insurance on every job

Staff cleaning versus specialist work
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
FAQs for Petteridge
Can a school’s ventilation in Petteridge be done out of term time?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Petteridge. Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we will fit the work in.
Can you get to a site in Petteridge?
Yes. Villages and rural sites across the South East are part of our work, Petteridge included. Let us know about access, parking and anything unusual about getting there when you book.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with the details in the report.
What if parts of the system cannot be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
What should I send you?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
What a clean won’t put right
Not every problem is solved by AHU cleaning, and we’ll tell you before we start. It won’t put right:
- Leaking heating or cooling coils
- Breakdowns that need a mechanical engineer
- Building management system faults
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly before booking.
