AHU cleaning in Netley Marsh
If the units serving a building in Netley Marsh have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. Common call-outs are for stale or musty smells from the ventilation and dust built up on fan impellers, across internal panels, drain trays and filter sections.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Keeping the system healthy
After the visit, a few habits help the work last:
- Keep filter changes on time and recorded
- Note any water around the unit or leaks below it
- Check the drain tray is emptying during routine visits
- Report stiff or damaged access doors
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
Why act early in Netley Marsh
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. In a place like Netley Marsh, ductwork and fans are easy to forget until something goes wrong.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

What we’re called out for in Netley Marsh
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
The symptoms we’re asked about most are:
- Air handling units with blocked filters
- Condensate trays that won’t empty
- Fan sections that haven’t been cleaned in years
- Stale or musty smells from the ventilation
For schools like Netley Marsh Church of England Infant School, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before booking

- What hours they’ll be on site
- How VAT is shown on the quote
- Which accreditations they hold, and whether you can check them
In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
How the visit works
Every visit runs to the same pattern: protect the area, make the system safe, carry out the AHU cleaning, clear away and leave you the report. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. Pictures of the system and its access let us plan the work in Netley Marsh before we set off.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use

Advice
FAQs for Netley Marsh
Do you work in villages like Netley Marsh?
Yes. Villages and rural sites across the South East are part of our work, Netley Marsh included. A survey first, from photos or a visit, means we arrive with the right kit.
Do you clean school ventilation in Netley Marsh in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Netley Marsh, the Food Standards Agency lists about 14 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you phone us on 0345 646 2711 or send us an email, and we will fit the work in.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
How do you keep the site clean during the work?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.

How the job changes from site to site
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
Drain trays
Older trays can corrode and start leaking. We record their condition with pictures so you can decide on any repairs.
What affects the cost of AHU cleaning
The price is fixed before any work begins. It’s based on:
- Travel, parking and unloading
- The condition we find in the survey
- How easy every part is to reach
- Site requirements such as sign-in and permits
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, ring 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.
Helping us quote
You do not need the technical terms. It helps if you can send:
- Any previous report or certificate
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, call us on 0345 646 2711 or email us.
