Advice
How we handle AHU cleaning in Coxhill Green
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. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. We are often asked to deal with plant that needs cleaning after a refit and leaves and litter drawn into the unit, on supply and extract fans, filter sections and drain trays.
Somewhere as small as Coxhill Green, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey, before we quote.

AHU cleaning around Coxhill Green
There are about 4 schools, colleges and universities and 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 Coxhill Green. Busy, occupied buildings like these are where clean supply air matters most. About 24 miles out from central London, Coxhill Green is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you. Coxhill Green’s nearest hospital, Brookwood Hospital, is about 2.4 miles south.

For schools like St Lawrence CofE (Aided) Primary School, the holidays are the usual time to inspect and clean ventilation.

Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
What we are called out for in Coxhill Green
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
If you notice any of these, it’s worth a diagnosis:
- Dust built up on fan impellers
- Air handling units due a clean after building work
- Intake sections clogged with outdoor debris
- Coils clogged with dust and debris
If you run a surgery, dental practice or care home near Coxhill Green, clean ventilation matters as much to you as to a hospital like Brookwood Hospital (about 2.4 miles south).
Before you book anyone

- What hours they’ll be on site
- Whether a survey comes first
- When the next visit should be, and why
What staff can safely do
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Why deal with it now?
Stuffy rooms and stale smells in a building in Coxhill Green can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. Our emergency line runs 24/7, but a planned visit to Coxhill Green is calmer for everyone.
