AHU Cleaning in Marlpit Hill
Need AHU cleaning in Marlpit Hill? We survey first, send you a fixed quote and work around your opening hours, then sign off with a report and photos.
- Air handling units never cleaned inside
- Plant that needs cleaning after a refit
- Condensate trays that won’t empty
When to call us in Marlpit Hill
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
Any of these means the system needs a check-up:
- Dust-coated heating and cooling coils
- Filters that are clogged or overdue
- Blocked condensate drains and slimy trays
- Air handling units due a clean after building work
Wherever a school like Edenbridge Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

AHU cleaning in Marlpit Hill, done properly
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. If you’re dealing with stale or musty smells from the ventilation and filters that are clogged or overdue, we can put it right.
For a building in or near Marlpit Hill, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same 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 carry full insurance.

Marlpit Hill buildings and their air
There are about 5 care, childcare and hospital premises on the FSA’s food hygiene register within roughly a mile and a half of the centre of Marlpit Hill. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Tandridge Priory is the nearest hospital, about 3.4 miles north-west of Marlpit Hill. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. At about 21 miles from central London, Marlpit Hill sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site.
If you run an office near Edenbridge station, its supply ductwork can gather dust for years before anyone looks inside. Tandridge Priory, about 3.4 miles north-west, is the nearest hospital to Marlpit Hill, and healthcare sites of every size need their supply air kept clean.
Marlpit Hill is about 7 miles north-east of East Grinstead, in Kent.

Looking after it afterwards
So the system stays in good health:
- Don’t ignore odours coming through the grilles
- Do not store bins or materials near the intake
- Note any water around the unit or leaks below it
- Keep filter changes on time and recorded
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. 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. If you can send photos, we can arrive in Marlpit Hill knowing what to expect.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure someone can let us in and lock up afterwards
- Dig out any earlier paperwork for the system

Honest limits
A few issues sit outside what this work can do:
- Coils that are corroded or leaking and need replacing
- Faulty motors, drives or bearings
- Ductwork downstream of the unit, which is a separate clean
If you are not sure, just phone us on 0345 646 2711 or email us and we’ll give you a straight answer.
Where we work
- Internal panels
- Supply and extract fans
- Filter sections
- Dampers and louvres
- Heating and cooling coils
- Drain trays
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. Somewhere as small as Marlpit Hill, losing a kitchen or building to a fault is felt by everyone who uses it.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.
