AHU cleaning for kitchens and businesses in Barford St Michael
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. Common call-outs are for intake sections clogged with outdoor debris and air handling units due a clean after building work, across filter sections, internal panels and drain trays.
In a village or hamlet like Barford St Michael, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Is a quote from photos possible?

What does TR19 mean?

How long does an AHU clean take?
It takes from a few hours for a compact unit to a day or more for a large one. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.

Why deal with it now?
Standing water in a drain tray doesn’t clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. With notice, the visit to Barford St Michael can be fitted around your bookings and events.

When to call us in Barford St Michael
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
The symptoms we’re asked about most include:
- Filters that are clogged or overdue
- Dust built up on fan impellers
- Units needing a clean before a new tenant or handover
- Coils clogged with dust and debris
Healthcare ventilation, from large hospitals like Horton General Hospital (about 4.6 miles north) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before you book
- How VAT is shown on the quote
- If the quote is a fixed price or an estimate
- Whether a survey comes first
- What hours they’ll be on site

What your team can do, and what needs us
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, and that’s where we come in.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. A few photos of the system help us make the most of a visit to a place like Barford St Michael.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.

Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Look at the condensate drain whenever the unit is serviced
- Stick to the filter change plan
- Book the next check in line with the report
- Report musty smells from the vents right away
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:

- Airflow problems caused by the system’s design
- Leaking heating or cooling coils
If you’re not sure, just call us on 0345 646 2711 or drop us a line and we will give you a straight answer before booking.
