AHU cleaning in West Tisted, done properly
We clean air handling units for buildings in West Tisted and across Hampshire, 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. We are often asked to deal with intake sections clogged with outdoor debris and dirty coils holding back the airflow, across internal panels, heating and cooling coils and dampers and louvres.
In a village or hamlet like West Tisted, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
A written report with pictures follows every visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The condition we find in the survey
- One-off work versus a regular cycle
- Site rules, permits and inductions
- The times the site is available
What you pay depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- Your opening hours and when the area is out of use
- Photos showing the whole system and its surroundings
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before we start.

What we do, step by step
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. We agree a date with you, plan the drive to West Tisted and turn up when the site is quiet.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Allow time for equipment near the work to be turned off and cool down
- Move anything stored near the system

Your questions about AHU cleaning in West Tisted
Is West Tisted in your area for AHU cleaning?
Yes, West Tisted is covered. Just call 0345 646 2711 or email us with a few details of the site.
Can you come to West Tisted after we close?
Yes, out-of-hours work is a big part of what we do. The work in West Tisted can fit around your hours. When you phone us on 0345 646 2711 or email us, mention when the site is quiet.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
How long does it take to clean an air handling unit?
Cleaning takes anything from half a day for one small unit to several shifts for a plant room full of them. Bigger units can be phased, and you can give us a ring on 0345 646 2711, or email photos to plan it.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Ring any time and tell us what’s happened.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
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 if it’s an emergency, call us any time.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
Different parts, different methods
Internal casing and panels
We open each section through its doors and close them securely when we are done before the unit is handed back.
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.
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Coils that are corroded or leaking and need replacing
- Problems with the unit’s controls or sensors
- Breakdowns that need a mechanical engineer
If in doubt, phone us on 0345 646 2711, or send details by email and we’ll say what we think before booking.
Parts of the system we cover
- Dampers and louvres
- Supply and extract fans
- Internal panels
- Filter sections
- Drain trays
- Heating and cooling coils
Why it’s worth doing now in West Tisted
Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. In a place like West Tisted, ductwork and fans are easy to forget until something goes wrong.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
Why us?
- A fixed price before any work starts
- One number for every site across the South East and London
- CHAS and SafeContractor accredited, with ISO 9001
- We diagnose before we treat

Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Clear leaves and litter away from the intake
- Make sure condensate is draining away
- Report stiff or damaged access doors
- Store the TR19 paperwork where auditors can find it
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
