Surrey · Air handling unit cleaning
Staines-upon-Thames AHU cleaning
One call covers air handling unit cleaning in Staines-upon-Thames, from survey to sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Dust built up on fan impellers
- Dirty filters cutting the airflow
- Units that have only ever had filter changes
Between visits
So the system stays in good health:
- Keep the area around the fresh air intake clear
- Book the next check in line with the report
- Flag stale or damp smells in the supply air
- Look at the condensate drain whenever the unit is serviced
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
How we handle AHU cleaning in Staines-upon-Thames
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. Typical jobs include dirty fans and fan housings and intake sections clogged with outdoor debris, across supply and extract fans, drain trays and filter sections.
In Staines-upon-Thames, ventilation in schools and offices is cleaned when the building is quiet: out of hours, at weekends or during the holidays.
A written report with photos follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

How often do AHUs need cleaning?

What happens on the day
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes anything from half a day for one small unit to several shifts for a plant room full of them. Sites in a town like Staines-upon-Thames rarely need to lose trading hours, as the work fits around them.
- 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.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Before we arrive

How we price AHU cleaning
The survey tells us what the work involves. The main factors are:
- Travel, parking and unloading
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
- When the work can happen, such as evenings, overnight or weekends
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- Any previous report or certificate
- When the site is open and when it’s quiet
- Any symptoms, from odd noises to smells or leaks
- A few general shots of the system
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Then phone us on 0345 646 2711, or email photos.
Honest limits
We will not sell you work that does not address the problem, so here are the limits:
- A system that is undersized for the building
- Leaking heating or cooling coils
- The supply and extract ducts, quoted separately
Not sure which it is? You can call 0345 646 2711 or email us and we’ll tell you honestly.
What the work covers

Do you need AHU cleaning in Staines-upon-Thames?
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.
What we’re most often called out for:
- Dirty filters cutting the airflow
- Dirty fans and fan housings
- Plant that needs cleaning after a refit
- Plant that has been serviced but not cleaned

Why deal with it now?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. Each month of use adds to the build-up, so a site in Staines-upon-Thames is better off booking it now.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so there are no surprises.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
