FAQs for Brill
Can the work in Brill be done at night or at weekends?
Yes, we can come after you close and finish before you open. It means the site in Brill keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Will you come out to Brill?
Yes, Brill is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and leave the area clean.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How long does it take to clean an air handling unit?
Typically the clean takes one overnight shift for many single units, with bigger plant phased. The shutdown is planned to fit, including evenings or weekends.
AHU cleaning in Brill
If the units serving a building in Brill have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Typical jobs include filters that are clogged or overdue and condensate trays that won’t empty, across dampers and louvres, heating and cooling coils and filter sections.
For a building in or near Brill, 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.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
What we do, step by step
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. A few photos of the system help us make the most of a visit to a place like Brill.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Find the previous report, if there is one
- Arrange a key holder or contact on site
- Mention any parking or loading restrictions

Around Brill
In Brill, that means kitchens and buildings near The Red Lion pub, among other places. For a walk, there’s Bernwood Meadows.
Why deal with it now?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. A planned visit to Brill is easier to arrange than an emergency callout.

- Coils that are corroded or leaking and need replacing

- Mechanical faults with motors, belts or bearings

How the job changes from site to site
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.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
When to call us in Brill
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.
Look out for any of the following:
- Air handling units never cleaned inside
- Odours coming through the supply air
- Drain trays holding standing water
- Dust built up on fan impellers
If you manage a school such as Brill Church of England School, ventilation cleaning is best booked for the holidays.

For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
