Air handling unit cleaning in Wolverton, Kent
Looking for AHU cleaning in Wolverton? We survey first, give you a fixed quote and work around your opening hours, finishing with a written report and pictures.
- Dust built up on fan impellers
- Units needing a clean before a new tenant or handover
- Drain trays holding standing water
How the visit works
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and we clear up before we go. Rural roads and tight entrances are worth telling us about before a visit to Wolverton.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Clear loose items from the work area
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about permits to work or site inductions
How to get a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

AHU cleaning in Wolverton, done properly
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. The work covers drain trays, filter sections and internal panels, and people most often call us about dust-coated heating and cooling coils and air handling units due a clean after building work.
For a building in or near Wolverton, 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.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Different parts, different methods
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.

Why it’s worth doing now in Wolverton
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Wolverton simpler. Our emergency line runs 24/7, but a planned visit to Wolverton is calmer for everyone.

Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Clear leaves and litter away from the intake
- Book the next check in line with the report
- Change filters on schedule and log each change
- Report stiff or damaged access doors
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
What we are called out for in Wolverton
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
Any of these means the system needs a check-up:
- Leaves and litter drawn into the unit
- Dust-coated heating and cooling coils
- Plant that needs cleaning after a refit
- Dirty filters cutting the airflow
School buildings such as Astor College for the Arts are normally done in the holidays, so classrooms aren’t disturbed.

What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
