AHU Cleaning in West Thorney
Need AHU cleaning in West Thorney? We diagnose first, fix the price and book the work around your hours, finishing with a written report and pictures.
- Drain trays holding standing water
- Dirty filters cutting the airflow
- Units needing a clean before a new tenant or handover
The process
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, and that takes one overnight shift for many single units, with bigger plant phased. A quick note on how to find the site and where to park makes a visit to West Thorney run smoothly.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Dig out any earlier paperwork for the system
- Mention any locked doors, roof access or ceiling voids
- Tell us about site rules, permits or sign-in

AHU cleaning in West Thorney, done properly
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from pictures or a site visit, and send you a fixed quote before any cleaning starts. The work covers supply and extract fans, dampers and louvres and internal panels, and people most often call us about units that have only ever had filter changes and fan sections that haven’t been cleaned in years.
Somewhere as small as West Thorney, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Managing agents and facilities teams in West Thorney
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.

What affects the cost of AHU cleaning
Every site gets its own quote. This is what makes a difference:
- Whether we need access equipment or extra panels
- Whether it’s a one-off visit or part of a schedule
- The condition of the system
- Travel, parking and unloading
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
What to send for a quote
To help us quote quickly, please include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The paperwork from the last visit, if you have it
- Your opening hours and when the area is out of use
- Any symptoms, from odd noises to smells or leaks
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, you get a fixed price before work begins.
What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Looking after it afterwards
A little care between visits keeps the system in better shape. Our advice:
- Report musty smells from the vents straight away
- Check the drain tray is emptying during routine visits
- Keep the area around the fresh air intake clear
- Plan the next inspection before the last report gets filed away
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.

The nearest hospital to West Thorney is Havant War Memorial Hospital, about 4.3 miles north-west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Healthcare buildings such as Havant War Memorial Hospital, about 4.3 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near West Thorney, yours matters too.

What happens if it’s left?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. It’s worth booking a check, because nobody sees inside a duct day to day.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

Your questions about AHU cleaning in West Thorney
Can you come to West Thorney after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in West Thorney does not have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Do you work in villages like West Thorney?
Yes. Villages and rural sites across the South East are part of our work, West Thorney included. Photos of the system and directions to the site help us plan the visit.
Do you offer emergency callouts?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
What do you do with what you remove?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
What a clean will not put right
Before booking, it helps to know what’s not included:
- Leaking heating or cooling coils
- Problems with the unit’s controls or sensors
- Faulty motors, drives or bearings
