AHU cleaning in Dorney
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. If you have dirty coils holding back the airflow and units that have only ever had filter changes, we can help, from supply and extract fans, filter sections and heating and cooling coils onwards.
Somewhere as small as Dorney, 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.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Keeping the system healthy
A little care between visits keeps the system in better shape. Our advice:
- Keep the certificate and photo report with the plant records
- Report water on the plant room floor
- Look at the condensate drain whenever the unit is serviced
- Change filters on schedule and log each change
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
What we do, step by step
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes half a day to a full day per unit, with large plant planned over several shifts. We agree a date with you, plan the drive to Dorney and turn up when the site is quiet.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Let us know about permits to work or site inductions
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure someone can let us in and lock up afterwards

Dorney buildings and their air
Going by the FSA’s register, there are about 5 schools, colleges and universities, about 8 care, childcare and hospital premises and about 3 hotels and B&Bs serving food within roughly a mile and a half of the centre of Dorney.

- Problems with the unit’s controls or sensors
- Ventilation that was badly designed in the first place
- Breakdowns that need a mechanical engineer

What the work covers
- Supply and extract fans
- Drain trays
- Heating and cooling coils
- Internal panels
- Dampers and louvres
- Filter sections
Why act early in Dorney
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. With notice, the visit to Dorney can be fitted around your bookings and events.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

Signs you need AHU cleaning in Dorney

Signs it’s time to call us include:
- Filters that are clogged or overdue
- Dust built up on fan impellers
- Plant that needs cleaning after a refit

Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Common questions in Dorney
Can a school’s ventilation in Dorney be done out of term time?
Yes, holiday work suits schools best. The FSA’s register shows about 5 schools and colleges with food registrations within roughly a mile and a half of Dorney. You can phone us on 0345 646 2711 or send us an email with the dates the site is empty.
Can you come to Dorney after we close?
Yes, nights and weekends are routine for us. The work in Dorney can fit around your hours. When you call 0345 646 2711 or use the quote form, mention when the site is quiet.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Do you look at the system first?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. Then you get a fixed quote.
Do you do ventilation duct cleaning too?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we’re fully insured.
How do you protect the area?
By covering it before any work starts. We keep the work contained and clean down when we finish.
