Why it’s worth doing now in Bosham
Stuffy rooms and stale smells in a building in Bosham can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. Somewhere as small as Bosham, losing a kitchen or building to a fault is felt by everyone who uses it.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.

AHU cleaning in Bosham, done properly
Where a building in Bosham has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. We are often asked to deal with plant that needs cleaning after a refit and air handling units never cleaned inside, across drain trays, internal panels and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
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.

Part by part
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
How the visit works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Bosham, let us know and we will plan around it.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Clear the space around the work
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us where we can park and unload
Getting a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Bosham buildings and their air

Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 57 miles out from central London, Bosham is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included. Bosham’s nearest hospital, St Richard's Hospital, is about 3.8 miles east.

How we price AHU cleaning
Before we fix a price, we need to know a few things. We check:
- When the work can happen, such as evenings, overnight or weekends
- Site rules, permits and inductions
- Whether we need access equipment or extra panels
- The scale of the work
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
- A few general shots of the system
- The postcode and the type of business
For a fixed quote, call 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We usually come back within one working day.
What AHU cleaning can’t fix
A few issues sit outside what this work can do:
- Breakdowns that need a mechanical engineer
- Damaged coils beyond cleaning
- Problems with the unit’s controls or sensors
If in doubt, call us on 0345 646 2711 or email us and we’ll say what we think before booking.
Parts of the system we cover
- Heating and cooling coils
- Filter sections
- Internal panels
- Supply and extract fans
- Dampers and louvres
- Drain trays
Signs you need AHU cleaning in Bosham
Wherever there’s a cooling coil, there’s condensate. 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.
Common reasons sites call us include:
- Rooms that smell stuffy when the system runs
- Dirty filters cutting the airflow
- Dirty fans and fan housings
- Condensate trays that will not empty
If you manage a school such as Bosham Primary School, ventilation cleaning is best booked for the holidays.
