AHU cleaning in Flackwell Heath
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. If you have debris and leaves in the fresh air intake and condensate trays that won’t empty, we can put it right.
In a place like Flackwell Heath, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
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.

Do you need AHU cleaning in Flackwell Heath?
Whatever surrounds a building in Flackwell Heath, 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.
Keep an eye out for these warning signs:
- Debris and leaves in the fresh air intake
- Units that have only ever had filter changes
- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
Healthcare buildings such as Hospital of St John the Baptist, about 2.5 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Flackwell Heath, yours matters too.

What affects the quote in Flackwell Heath
Before we fix a price, we need to know a few things. We look at:
- Whether several sites go on one quote
- Any permits to work or inductions
- How big the system is
- One-off work versus a regular cycle
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or use the quote form, and we’ll explain what it covers.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- Any previous report or certificate
- A few general shots of the system
- The roof, plant room or outside wall the system runs to
- Where the site is and what kind of site it is
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or drop us a line.
How it works
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 the same goes into the written report. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. Tell us when your site near Flackwell Heath is quiet and the visit will be booked for then.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Move anything stored near the system
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use
How to get a quote
If you need AHU cleaning in Flackwell Heath, ring 0345 646 2711, or email photos. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. A fixed quote normally follows within one working day.
Advice
Part by part
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
What happens if it’s left?
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Systems on quieter sites still build up dirt and wear, just more slowly.
What you pay depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so there are no surprises.
Why us?
- Every visit written up, with photos
- Work around your opening hours, with 24/7 emergency cover
- Trading since 2009
- Every job surveyed first

Flackwell Heath questions
Do you work overnight in Flackwell Heath?
Yes, nights and weekends are routine for us. The work in Flackwell Heath can fit around your hours. Just call 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Will you come out to Flackwell Heath?
Yes. Flackwell Heath 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.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
What about areas you can’t get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
How often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
What AHU cleaning can’t fix
In fairness, some problems need a different fix:
- Dirty ducts beyond the unit itself
- Controls and BMS settings that run the unit
- Ventilation that was badly designed in the first place
If you are not sure, just call 0345 646 2711 or email us and we will give you a straight answer before you book.
Parts of the system we cover
- Dampers and louvres
- Internal panels
- Filter sections

Landlords, agents and facilities managers
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
