Your questions about AHU cleaning in Crossbush
Is Crossbush within the area you cover?
Yes. Crossbush is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you come to Crossbush after we close?
Yes, nights and weekends are routine for us. That way a site in Crossbush doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
Do you look at the system first?
Yes. We always survey first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
Can you quote from photos?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with the details in the report.
What information do you need?
Where the site is, what it is and when it’s open, along with a few pictures and any previous report.
AHU cleaning in Crossbush, done properly
We clean air handling units for buildings in Crossbush and across West Sussex, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you’re dealing with fan sections that haven’t been cleaned in years and air handling units with blocked filters, we can help, from internal panels, supply and extract fans and drain trays onwards.
For a building in or near Crossbush, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Why act early in Crossbush
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. A planned visit to Crossbush is easier to arrange than an emergency callout.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.

What we are called out for in Crossbush
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.
If you notice any of these, it’s worth a diagnosis:
- Air handling units never cleaned inside
- Dirty coils holding back the airflow
- Dirty fans and fan housings
- Debris and leaves in the fresh air intake
Hospitals such as Arundel and District Hospital (about 1.5 miles north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Crossbush are no different.

Part by part
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Internal casing and panels
We open each section through its doors and close them securely when we are done, and check every one is shut.
What happens on the day
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. A quick note on how to find the site and where to park makes a visit to Crossbush run smoothly.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Let us know about parking and loading
- Dig out any earlier paperwork for the system
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. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

When something else is needed
AHU cleaning cannot fix everything, and we’ll tell you before we start. It does not solve:
- Airflow problems caused by the system’s design
- Coils that are corroded or leaking and need replacing
- Ductwork downstream of the unit, which is a separate clean
If you are not sure, just give us a ring on 0345 646 2711, or email photos and we will give you a straight answer.
What we work on in Crossbush
- Filter sections
- Dampers and louvres
- Internal panels
- Drain trays
- Supply and extract fans
- Heating and cooling coils
What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
