AHU cleaning in Westley
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. Typical jobs include units that have only ever had filter changes and air handling units with blocked filters, across dampers and louvres, heating and cooling coils and internal panels.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Keep the certificate and photo report with the plant records
- Stick to the filter change plan
- Clear leaves and litter away from the intake
- Make sure the unit’s access doors open easily
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Why act early in Westley
Stuffy rooms and stale smells in a building in Westley can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. It’s simpler to plan the work at Westley now than to arrange it in a hurry later.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.

What happens on the day
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere as small as Westley, the date and timings are agreed with you well before the day.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Let us know when the site is closed or quiet
- Let us know about permits to work or site inductions
- Clear the space around the work
Getting a quote
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 we start.
Advice
Common questions in Westley
Can you do AHU cleaning in Westley?
Yes, Westley is covered. Just phone us on 0345 646 2711 or email us with a few details of the site.
Do you work in villages like Westley?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
What accreditations do you have?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
What happens if you cannot reach some of it?
We record them on the report, with pictures where possible, and we explain what access is needed, such as extra access panels in ductwork.
Can you clean without disrupting the building?
Yes. Evening, overnight and weekend work is all possible, so offices, schools and shops can carry on.
What affects the quote in Westley
We do not publish a price list, because no two systems are the same. What we look at:
- How big the system is
- Where the site is and how we reach it
- Whether we need access equipment or extra panels
- How many systems or sites are involved
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- Photos showing the whole system and its surroundings
- The paperwork from the last visit, if you have it
- The times we could work without disrupting the site
- Any symptoms, from odd noises to smells or leaks
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
When to call us in Westley
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Any of these means the system needs a check-up:
- Intake sections clogged with outdoor debris
- Odours coming through the supply air
- Units that have only ever had filter changes
- Blocked condensate drains and slimy trays
Wherever a school like Sparsholt Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
