Air handling unit cleaning in Aston, Oxfordshire
One call covers AHU cleaning in Aston: survey, fixed quote, work and sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Stale or musty smells from the ventilation
- Blocked condensate drains and slimy trays
- Dirty fans and fan housings
Why deal with it now?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. Somewhere as small as Aston, losing a kitchen or building to a fault is felt by everyone who uses it.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Why Aston businesses choose us
- Survey first, then a fixed quote
- A written report with photos after each visit
- One contact for all your sites in London and the South East
- We are fully insured
About our AHU cleaning in Aston
Our AHU cleans for sites in Aston cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. The work covers dampers and louvres, filter sections and internal panels, and the jobs we see most are blocked condensate drains and slimy trays and fan sections that haven’t been cleaned in years.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Aston questions
Can you do AHU cleaning in Aston?
Yes. Our area runs across London and the South East, Aston included. A fixed quote normally follows within one working day of the survey details.
Can you come to Aston after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in Aston keeps running as normal. Tell us your opening hours when you ask for a quote.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, usually ready within one working day.
What do you clean inside the unit?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
Are you fully insured?
Yes. Full insurance covers our work and have been trading since 2009.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
What should I send you?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
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 else we do in Aston
For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
What affects the quote in Aston
We quote each job individually. These are the things that affect it:
- Parking and loading at the site
- The scale of the work
- Site requirements such as sign-in and permits
- The number of sites or systems
You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711 or send us an email, and we’ll talk you through it.
What to send for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes half a day to a full day per unit, with large plant planned over several shifts. A few pictures of the system help us make the most of a visit to a place like Aston.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Advice
Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Signs you need AHU cleaning in Aston
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Keep an eye out for these warning signs:
- Blocked condensate drains and slimy trays
- Odours coming through the supply air
- Plant that has been serviced but not cleaned
- Leaves and litter drawn into the unit
Around Aston, as anywhere, ventilation cleaning begins with an inspection.
What your quote should include
- When the next visit should be, and why
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- What paperwork you get at the end
- What insurance they carry
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- A system that is undersized for the building
- Dirty ducts beyond the unit itself
- Breakdowns that need a mechanical engineer
If you’re not sure, just phone us on 0345 646 2711 or use the quote form and we will give you a straight answer before booking.
