What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
AHU cleaning in Lower Eashing, done properly
We clean air handling units for buildings in Lower Eashing and across Surrey, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you have units that have only ever had filter changes and air handling units due a clean after building work, we can put it right, from dampers and louvres, heating and cooling coils and supply and extract fans onwards.
Somewhere as small as Lower Eashing, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- The scale of the work
- Whether several sites go on one quote
- How easy every part is to reach
- The times the site is available
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- When the site is open and when it’s quiet
- How we’d reach plant on a roof or in a plant room
- Your last certificate, test record or report
- Any symptoms, from odd noises to smells or leaks
To get a fixed quote, ring 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll typically have a quote within one working day.
What we do, step by step
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before we start, and the area around the work is covered and protected. On site, it takes one overnight shift for many single units, with bigger plant phased. If the van will struggle with a lane or gateway near Lower Eashing, let us know and we will plan around it.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Let us know when the site is closed or quiet
- Let us know about permits to work or site inductions

Advice
Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.

What we’re called out for in Lower Eashing
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
It’s time to book a visit if you see:
- Dirty coils holding back the airflow
- Leaves and litter drawn into the unit
- Air handling units due a clean after building work
- Odours coming through the supply air
Healthcare buildings such as Milford Hospital, about 1.7 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Lower Eashing, yours matters too.

- What records you’ll receive afterwards
- Whether the price is fixed
- What’s included in the scope, part by part

Leave it or put it right?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. Our emergency line runs 24/7, but a planned visit to Lower Eashing is calmer for everyone.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

Lower Eashing: your questions answered
Is Lower Eashing within the area you cover?
Yes, we work in villages as well as towns, and Lower Eashing is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Can ventilation in schools around Lower Eashing be cleaned out of term?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Lower Eashing. Tell us your holiday dates and we will book the visit for when the site is empty.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with the details in the report.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
What happens if you cannot reach some of it?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
How often do AHUs need cleaning?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
How much notice should we give?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Can you clean the AHU out of hours?
Yes. We time the work to fit the building’s hours. Healthcare and care settings are planned with staff.
