Great Wigborough AHU cleaning
Our technicians work in Great Wigborough on cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Fixed quotes, work around your opening hours and photo reports on every job.
- Drain trays holding standing water
- Dirty coils holding back the airflow
- Air handling units due a clean after building work
Different parts, different methods
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
AHU cleaning in Great Wigborough
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you’re dealing with blocked condensate drains and slimy trays and air handling units with blocked filters, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

How the visit works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, and that takes half a day to a full day per unit, with large plant planned over several shifts. If the van will struggle with a lane or gateway near Great Wigborough, let us know and we’ll plan around it.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- 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.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Let us know when the site is closed or quiet
- Tell us about site rules, permits or sign-in
- Find the previous report, if there is one

What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. A fault that closes a site in a village like Great Wigborough affects everyone who depends on it.
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

Signs you need AHU cleaning in Great Wigborough
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
If you notice any of these, it’s worth a diagnosis:
- Filters that are clogged or overdue
- Air handling units never cleaned inside
- Coils clogged with dust and debris
- Blocked condensate drains and slimy trays
Ventilation work in and around Great Wigborough is risk-based: inspect, then clean what needs it.
Before you book anyone
- What happens if part of the system cannot be accessed
- Exactly which parts of the system are covered
- When they can work, and whether that is outside your opening hours
- Proof of insurance
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
