Common problems we fix in North Marston
Whatever surrounds a building in North Marston, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
What we are most often called out for:
- Units that have only ever had filter changes
- Dust-coated heating and cooling coils
- Air handling units due a clean after building work
- Blocked condensate drains and slimy trays
If you run a surgery, dental practice or care home near North Marston, clean ventilation matters as much to you as to a hospital like Royal Buckinghamshire Hospital (about 5.9 miles south-east).

AHU cleaning in North Marston, done properly
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. We are often asked to deal with odours coming through the supply air and units needing a clean before a new tenant or handover, across filter sections, supply and extract fans and dampers and louvres.
In a village or hamlet like North Marston, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Common questions in North Marston

Where does the waste go?
It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.

Yes, of course. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.

How much notice should we give?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
How the visit works
The first job on site is protection: 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. For a village or hamlet like North Marston, tell us about narrow lanes, gates and parking when you book.
- 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.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Move anything stored near the system
- Mention any sign-in, permit or induction we need
Get a fixed 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.

How the job changes from site to site
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Managing agents and facilities teams in North Marston
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
We also work for facilities teams across offices, schools and healthcare across Buckinghamshire. Larger estates can be phased building by building to keep disruption down.
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Note any water around the unit or leaks below it
- Clear leaves and litter away from the intake
- Make sure condensate is draining away
- Stick to the filter change plan
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
