- Dirty fans and fan housings
- Air handling units with blocked filters
- Units needing a clean before a new tenant or handover
What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes from a few hours for a compact unit to a day or more for a large one. Where a site in Milton Keynes has more than one system, we can take them one at a time to keep the rest running.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Move anything stored near the system
- Have your last certificate or report to hand
How to get a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

AHU cleaning for kitchens and businesses in Milton Keynes
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. The work covers drain trays, dampers and louvres and supply and extract fans, and the jobs we see most are dirty coils holding back the airflow and plant that needs cleaning after a refit.
In a big place like Milton Keynes, one building can have several AHUs serving different zones. Filters, coils, drain trays and fans all need cleaning, and standing water in a drain tray is a common finding.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
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.

When to call us in Milton Keynes
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
Clients usually contact us after spotting something like this:
- Condensate trays that won’t empty
- Plant that has been serviced but not cleaned
- Debris and leaves in the fresh air intake
- Odours coming through the supply air
Classrooms and halls at schools such as Summerfield School are easiest to work in when pupils are away.

For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
How the job changes from site to site
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Report stiff or damaged access doors
- File each AHU report in the maintenance log
- Look at the condensate drain whenever the unit is serviced
- Report water on the plant room floor
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
