AHU cleaning for kitchens and businesses in Sandown
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. The work covers heating and cooling coils, supply and extract fans and dampers and louvres, and common reasons people get in touch are air handling units due a clean after building work and dust built up on fan impellers.
Visits to a place like Sandown are fitted around opening hours. The method doesn’t change: inspect first, clean, then record what was done.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Signs you need AHU cleaning in Sandown
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Keep an eye out for these warning signs:
- Dirty fans and fan housings
- Coils clogged with dust and debris
- Air handling units never cleaned inside
- Debris and leaves in the fresh air intake
For schools like The Bay Church of England School, the holidays are the usual time to inspect and clean ventilation.

What the work involves, part by part
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
What affects the cost of AHU cleaning
The diagnosis comes before the price. We look at:
- The condition we find in the survey
- One-off work versus a regular cycle
- The number of sites or systems
- Working hours and out-of-hours timing
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

- Detail shots of panels, filters and grilles

Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Is there a survey before the work?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.
Why it’s worth doing now in Sandown
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. It’s better to plan the work at a site near Sandown than wait for a failure.
