AHU cleaning in Furnace Wood
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote before any cleaning starts. Typical jobs include plant that has been serviced but not cleaned and dirty fans and fan housings, across supply and extract fans, internal panels and filter sections.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
A written report with photos follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Common questions in Furnace Wood
Do you work overnight in Furnace Wood?
Yes, evening, overnight and weekend work is normal for us. It means the site in Furnace Wood keeps running as normal. When you give us a ring on 0345 646 2711 or use the quote form, mention when the site is quiet.
Is Furnace Wood within the area you cover?
Yes. Furnace Wood is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
How much notice do you need?
Earlier is better, especially for out-of-hours work. We usually quote within one working day, and there’s a 24/7 line for emergencies.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Managing agents and facilities teams in Furnace Wood
Facilities teams in offices, schools and healthcare sites book us too in Furnace Wood and across West Sussex. Work can be phased by floor, building or site to keep disruption down.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- Working hours and out-of-hours timing
- Whether it’s a one-off visit or part of a schedule
- Site requirements such as sign-in and permits
- How easy every part is to reach
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
What we need to know
Before you ask for a quote, gather:
- Your last certificate, test record or report
- Problems your staff have spotted
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any access panels or hatches you can see

Do you need AHU cleaning in Furnace Wood?
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Clients typically contact us when they notice something like this:
- Dirty filters cutting the airflow
- Dirty fans and fan housings
- Rooms that smell stuffy when the system runs
- Leaves and litter drawn into the unit
Hospitals such as Queen Victoria Hospital (about 3.1 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Furnace Wood are no different.

Part by part
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Ventilation in Furnace Wood buildings

How to get a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Advice
When it’s something else
Before booking, it helps to know what’s not included:
- Airflow problems caused by the system’s design
- The supply and extract ducts, quoted separately
- Controls and BMS settings that run the unit
