Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
How we handle AHU cleaning in Kippington
Our AHU cleaning covers sites in Kippington and the rest of Kent, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you have dirty coils holding back the airflow and air handling units never cleaned inside, we can put it right.
In a place like Kippington, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
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 carry full insurance.

Why deal with it now?
Stuffy rooms and stale smells in a building in Kippington can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. It’s better to plan the work at a site near Kippington than wait for a failure.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before we start.

Common problems we fix in Kippington
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
Signs it’s time to call us include:
- Blocked condensate drains and slimy trays
- Filters that are clogged or overdue
- Fan sections that haven’t been cleaned in years
- Dirty coils holding back the airflow
If you manage offices or shops near Sevenoaks station, their ventilation can be inspected and cleaned out of hours.

- Whether the quote shows VAT
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether they recommend a next date
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Change filters on schedule and log each change
- Clear leaves and litter away from the intake
- Look at the condensate drain whenever the unit is serviced
- File each AHU report in the maintenance log
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
Ventilation in Kippington buildings
The FSA’s food hygiene register lists about 13 schools, colleges and universities and about 11 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service within 1.5 miles or so of the middle of Kippington. Busy, occupied buildings like these are where clean supply air matters most. For Kippington, the closest hospital is Sevenoaks Hospital, roughly 1.4 miles north-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Kippington, about 20 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.
School buildings such as St Thomas' Catholic Primary School are usually done in the holidays, so classrooms aren’t disturbed. Healthcare buildings such as Sevenoaks Hospital, about 1.4 miles north-east, depend on their ventilation; if you manage a surgery, clinic or care home near Kippington, yours matters too.

What affects the cost of AHU cleaning
Your quote is based on your site. We take into account:
- How big the system is
- Whether we need access equipment or extra panels
- The number of sites or systems
- Site requirements such as sign-in and permits
The cost 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 any work starts, so you know where you stand.
What we need to know
We can often survey from pictures. Try to include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is
Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
How the visit works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Your opening hours decide when we come to Kippington, not ours.
- 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.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Tell us about site rules, permits or sign-in
- Find the previous report, if there is one
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with photos where it helps.
What about areas you cannot get to?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. We typically quote within one working day, and emergencies are covered by our 24/7 line.
How long does an AHU clean take?
Expect it to take one overnight shift for many single units, with bigger plant phased. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
