What we are called out for in Middle Aston
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Middle Aston, that’s air they breathe for hours at a time.
Signs it’s time to call us include:
- Intake sections clogged with outdoor debris
- Blocked condensate drains and slimy trays
- Odours coming through the supply air
- Dust-coated heating and cooling coils
Ventilation work in and around Middle Aston is risk-based: inspect, then clean what needs it.

AHU cleaning in Middle Aston, done properly
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. Common call-outs are for blocked condensate drains and slimy trays and intake sections clogged with outdoor debris, on filter sections, dampers and louvres and heating and cooling coils.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How it works
Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and leave you the report. The visit itself takes from a few hours for a compact unit to a day or more for a large one. Visits to a village like Middle Aston are booked in advance, at a time that suits whoever runs the site.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Let us know about permits to work or site inductions
- Plan for cooking equipment or plant to be off before we arrive
- Find the previous report, if there is one

More services for Middle Aston
In-house cleaning or a specialist?
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 won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Questions from Middle Aston
Will you come out to Middle Aston?
Yes, Middle Aston is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Do you work overnight in Middle Aston?
Yes, nights and weekends are routine for us. The work in Middle Aston can fit around your hours. Tell us your opening hours when you ask for a quote.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What’s included in an AHU clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, typically ready within one working day.
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, with new panels fitted where necessary.

Looking after it afterwards
After the visit, a few habits help the work last:
- Report water on the plant room floor
- Check the drain tray is emptying during routine visits
- Change filters on schedule and log each change
- Make sure the unit’s access doors open easily
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
Why it’s worth doing now in Middle Aston
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. A fault that closes a site in a village like Middle Aston affects everyone who depends on it.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before work begins.
