AHU cleaning in Birchden
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so you can see the unit’s condition for yourself. Typical jobs include dust built up on fan impellers and drain trays holding standing water, on drain trays, internal panels and supply and extract fans.
Work in a small place like Birchden starts with agreeing access and timings.
A written report with pictures follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Between visits
To keep the system working properly between visits:
- Book the next check in line with the report
- Do not ignore odours coming through the grilles
- Keep the certificate and photo report with the plant records
- Clear leaves and litter away from the intake
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Why act early in Birchden
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. Somewhere as small as Birchden, losing a kitchen or building to a fault is felt by everyone who uses it.
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.

What the work involves, part by part
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Birchden questions
Do you offer AHU cleaning in Birchden?
Yes. We work across London and the South East, and Birchden is part of that. A fixed quote usually follows within one working day of the survey details.
Can the work in Birchden be done at night or at weekends?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can quote for both.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We will flag anything we notice during the clean.
How long does an AHU clean take?
It takes anything from half a day for one small unit to several shifts for a plant room full of them. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
How the visit works
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere like Birchden, lanes, gates and parking are worth mentioning in advance.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend
- Let us know about parking and loading
Ask for a quote
Photos are enough for some jobs, while others need a look on site. 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.
Related advice
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Signs you need AHU cleaning in Birchden
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Signs it’s time to call us include:
- Air handling units never cleaned inside
- Condensate trays that will not empty
- Dirty coils holding back the airflow
- Filters that are clogged or overdue
Wherever a school like Groombridge St Thomas' Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
