AHU cleaning in Mortimer, done properly
Where a building in Mortimer has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. Typical jobs include debris and leaves in the fresh air intake and filters that are clogged or overdue, across filter sections, internal panels and dampers and louvres.
Smaller buildings around Mortimer often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

How we price AHU cleaning
You will get a fixed price before any work starts. It takes into account:
- A single visit or a regular plan
- Parking and loading at the site
- How big the system is
- Working hours and out-of-hours timing
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call us on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Your opening hours and when the area is out of use
- Your last certificate, test record or report
- Where the site is and what kind of site it is
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711, or send details by email.

Multi-site and managed buildings
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Facilities teams in offices, schools and healthcare sites book us too across West Berkshire. Larger estates can be phased building by building to keep disruption down.
When to call us in Mortimer
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
Keep an eye out for any of the following:
- Coils clogged with dust and debris
- Leaves and litter drawn into the unit
- Air handling units due a clean after building work
- Air handling units never cleaned inside
Around Mortimer, as anywhere, ventilation cleaning begins with an inspection.
Questions to ask before booking
- Whether a written report and photos are included
- When the next visit should be, and why
- What hours they’ll be on site
- Proof of accreditation you can verify

Part by part
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Book the next check in line with the report
- Store the TR19 paperwork where auditors can find it
- Keep the area around the fresh air intake clear
- Stick to the filter change plan
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
How the visit works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. We plan the journey to Mortimer and bring what the job is likely to need.
- The survey covers the unit, its access and how it can be shut down.
- 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.
Before we arrive
- Agree a time when the area can be out of use
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
Ask for a quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
