AHU cleaning for kitchens and businesses in Ascott Earl
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you are dealing with air handling units due a clean after building work and dust built up on fan impellers, we can help, from dampers and louvres, supply and extract fans and drain trays onwards.
Somewhere as small as Ascott Earl, ducted ventilation is normally 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.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What we do, step by step
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. We agree a date with you, plan the drive to Ascott Earl and turn up when the site is quiet.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Move anything stored near the system
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Then call us on 0345 646 2711 or email us.

Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Stick to the filter change plan
- Report water on the plant room floor
- Keep the area around the fresh air intake clear
- Report musty smells from the vents straight away
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.

Part by part
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
- Whether it’s a one-off visit or part of a schedule
- Site rules, permits and inductions
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, ring 0345 646 2711, or email photos for straight advice and a fixed quote.
What to send for a quote
What to send for a quote:
- How we’d reach plant on a roof or in a plant room
- The site address and the type of premises
- Any access panels or hatches you can see
- Any symptoms, from odd noises to smells or leaks
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, give us a ring on 0345 646 2711 or drop us a line.
Why act early in Ascott Earl
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, ready to show anyone who asks. Out of sight is the usual reason a rural system goes too long without attention.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

- A single point of contact for sites across the South East and London

Are you accredited?

Which kinds of sites do you work on?

Is a quote from pictures possible?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Signs you need AHU cleaning in Ascott Earl
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Most sites get in touch after spotting something like this:
- Leaves and litter drawn into the unit
- Blocked condensate drains and slimy trays
- Filters that are clogged or overdue
- Stale or musty smells from the ventilation
Workplaces around Ascott-Under-Wychwood station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
What to look for in a quote
- Whether a written report and photos are included
- Whether they’re fully insured
- If the quote is a fixed price or an estimate
- Which accreditations they hold, and whether you can check them
When something else is needed
We’d rather tell you now than book work that won’t help, so here are the limits:
- Problems with the unit’s controls or sensors
- A system that is undersized for the building
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can ring 0345 646 2711 or email us and we will tell you honestly.
