AHU cleaning in Aston Tirrold, done properly
We clean air handling units for buildings in Aston Tirrold and across Oxfordshire, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers internal panels, supply and extract fans and filter sections, and people most often call us about condensate trays that won’t empty and stale or musty smells from the ventilation.
In a village or hamlet like Aston Tirrold, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
A written report with pictures 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 it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Rural roads and tight entrances are worth telling us about before a visit to Aston Tirrold.
- 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.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Tell us about site rules, permits or sign-in
- Make sure someone can let us in and lock up afterwards
Get a fixed quote
We don’t publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then send you a fixed quote. To get going, phone us on 0345 646 2711 or email us.
Advice
How the job changes from site to site
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so repairs can be planned.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
When something else is needed
Before you book, it helps to know what’s not included:
- Coils that are corroded or leaking and need replacing
- Controls and BMS settings that run the unit
- The supply and extract ducts, quoted separately
Not sure which it is? You can phone us on 0345 646 2711 or email us and we’ll tell you honestly.
What the work covers
- Heating and cooling coils
- Filter sections
- Dampers and louvres
- Supply and extract fans
- Internal panels
- Drain trays
Keeping the system healthy
After the visit, a few habits help the work last:
- Watch for drips or damp patches near the plant
- Make sure condensate is draining away
- Diary the inspection date recommended in the report
- Store the TR19 paperwork where auditors can find it
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
What affects the cost of AHU cleaning
You will get a fixed price before we start. It’s based on:
- The size of the system
- Any permits to work or inductions
- Where the site is and how we reach it
- How easy every part is to reach
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Any access panels or hatches you can see
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- When the site is open and when it’s quiet
- Any previous report or certificate
Getting a quote does not take long. Call or email with a few details and you will usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Do you need AHU cleaning in Aston Tirrold?
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.
Most sites get in touch when they notice one of these:
- Units that have only ever had filter changes
- Leaves and litter drawn into the unit
- Filters that are clogged or overdue
- Drain trays holding standing water
In Aston Tirrold, we look inside the system before deciding what needs cleaning.
What your quote should include
