How we handle AHU cleaning in Hook Norton
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. If you’re dealing with dirty coils holding back the airflow and blocked condensate drains and slimy trays, we can put it right, from filter sections, internal panels and drain trays onwards.
In a place like Hook Norton, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.
When it’s something else
Before booking, it helps to know what’s not included:
- Coils that are corroded or leaking and need replacing

- Faulty motors, drives or bearings
If in doubt, call 0345 646 2711, or email photos and we will say what we think.

Aftercare tips
Once we’ve finished, these simple steps help:
- Book the next check in line with the report
- Keep the area around the fresh air intake clear
- Look at the condensate drain whenever the unit is serviced
- Stick to the filter change plan
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
How it works
A visit follows the same order every time: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and hand over the paperwork. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Tell us when your site near Hook Norton is quiet and the visit will be booked for then.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.

- We close up the unit and send the certificate and before and after photos.
