How we handle AHU cleaning in Northease
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. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you have dirty fans and fan housings and plant that needs cleaning after a refit, we can help.
Work in a small place like Northease starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. The timing of a visit to Northease 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.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Have your last certificate or report to hand
- Plan for cooking equipment or plant to be off before we arrive
- Mention any sign-in, permit or induction we need
Getting 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. Add the site type and your opening hours, and many jobs can be priced from that alone.

Northease: your questions answered
Can you get to a site in Northease?
Yes. Northease is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
Is AHU cleaning available in Northease?
Yes, Northease is covered. Get in touch with the details and we will arrange a survey.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we’ll ask.
How long does it take to clean an air handling unit?
Cleaning takes anything from half a day for one small unit to several shifts for a plant room full of them. Large plant can be split over several shifts, and you can call us on 0345 646 2711 or drop us a line to plan it.
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 survey both on the same visit.
How do you keep the site clean during the work?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
How far ahead should we book?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
What we’re called out for in Northease
Whatever surrounds a building in Northease, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.
Common reasons sites call us are:
- Dirty filters cutting the airflow
- Rooms that smell stuffy when the system runs
- Condensate trays that won’t empty
- Dirty coils holding back the airflow
For schools like Priory School, the holidays are the usual time to inspect and clean ventilation.
What your quote should include
- What hours they’ll be on site
- Whether inaccessible sections are listed on the report
- How VAT is shown on the quote
- Whether a survey comes first

How we price AHU cleaning
The diagnosis comes before the price. The main factors are:
- The scale of the work
- One-off work versus a regular cycle
- Where the site is and how we reach it
- How many systems or sites are involved
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Helping us quote
To speed up the quote, send us:
- The times we could work without disrupting the site
- Any access panels or hatches you can see
- A few general shots of the system
- The paperwork from the last visit, if you have it
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before work begins.
What else we do in Northease
How the job changes from site to site
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too across East Sussex. Work can be phased by floor, building or site to keep disruption down.
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.
