AHU cleaning in Brenchley
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. Common call-outs are for odours coming through the supply air and filters that are clogged or overdue, on supply and extract fans, drain trays and internal panels.
Work in a small place like Brenchley starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Aftercare tips
Results last longer with the right care. We suggest:
- Look at the condensate drain whenever the unit is serviced
- Make sure the unit’s access doors open easily
- Book the next check in line with the report
- Do not ignore odours coming through the grilles
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.

Questions from Brenchley
Do you work at weekends in Brenchley?
Yes, we can come after you close and finish before you open. The work in Brenchley can fit around your hours. Your opening times are the first thing we ask for.
Do you do school ventilation cleaning in Brenchley in the summer holidays?
Yes, and it’s the easiest time to do it. Around Brenchley, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you ring 0345 646 2711 or drop us a line, and we’ll fit the work in.
How do you protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What happens to the waste?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
What affects the quote in Brenchley
Sites vary more than people expect. The main factors:
- How many systems or sites are involved
- The condition of the system
- The times the site is available
- How big the system is
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before any work starts.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- The paperwork from the last visit, if you have it
- When the site is open and when it’s quiet
- The postcode and the type of business
- How we’d reach plant on a roof or in a plant room
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
How it 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. It takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. The timing of a visit to Brenchley is set by you, and the travel is our side of the planning.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Mention any parking or loading restrictions
- Clear the space around the work
Ask for a quote
Getting a quote does not take long. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Signs you need AHU cleaning in Brenchley
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Clients normally contact us after spotting something like this:
- Air handling units due a clean after building work
- Intake sections clogged with outdoor debris
- Drain trays holding standing water
- Air handling units never cleaned inside
If you manage a school such as Brenchley and Matfield Church of England Primary School, ventilation cleaning is best booked for the holidays.
Questions to ask before you book
- When the next visit should be, and why
- Proof of insurance
- When they can work, and whether that is outside your opening hours
- If the quote is a fixed price or an estimate
How the job changes from site to site
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
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.
What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
