AHU cleaning in West Liss
We clean air handling units for buildings in West Liss and across Hampshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers heating and cooling coils, dampers and louvres and internal panels, and common reasons people get in touch are intake sections clogged with outdoor debris and stale or musty smells from the ventilation.
For a building in or near West Liss, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Questions from West Liss
Can you work in West Liss outside opening hours?
Yes, nights and weekends are routine for us. Your customers, staff or residents in West Liss needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Do you cover West Liss for AHU cleaning?
Yes, we work in West Liss and the places around it. You can ring 0345 646 2711 or send us an email and let us know what needs doing.
Can you price the work without visiting?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
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 quote for both.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We’ll flag anything we notice during the clean.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
What should I send you?
Where the site is, what it is and when it’s open, along with a few pictures and any previous report.

Take a look at how cleaning jobs are priced and how to check a contractor.
Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Aftercare tips
How long the results last depends on use and care. We suggest:
- Flag stale or damp smells in the supply air
- Book the next check in line with the report
- File each AHU report in the maintenance log
- Clear leaves and litter away from the intake
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
Ventilation in West Liss buildings
There are about 8 care, childcare and hospital premises on the FSA’s food hygiene register within about 1.5 miles of central West Liss. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 3.2 miles south-west of West Liss is Petersfield Community Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. At about 47 miles from central London, West Liss sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you.
If you manage offices or shops near Liss station, their ventilation can be inspected and cleaned out of hours. Healthcare ventilation, from large hospitals like Petersfield Community Hospital (about 3.2 miles south-west) to small clinics, depends on clean filters, coils and ducts. Wherever a school like Liss Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What we do, step by step
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes from a few hours for a compact unit to a day or more for a large one. Somewhere as small as West Liss, the date and timings are agreed with you well before the day.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Move anything stored near the system
- Agree a time when the area can be out of use
- Dig out any earlier paperwork for the system
Getting a quote
To help us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Then call us on 0345 646 2711, or email photos.
Advice
Part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
Landlords, agents and facilities managers
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
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.
How we price AHU cleaning
Sites vary more than people expect. The main factors:
- A single visit or a regular plan
- Whether we need access equipment or extra panels
- Whether several sites go on one quote
- The scale of the work
The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- The paperwork from the last visit, if you have it
- The times we could work without disrupting the site
- A few general shots of the system
- Where the plant sits or the system leaves the building, such as a roof or outside wall
