What AHU cleaning can’t fix
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It does not solve:
- Faulty motors, drives or bearings
- The supply and extract ducts, quoted separately
- A system that is undersized for the building
If you are not sure, just call 0345 646 2711 or use the quote form and we’ll give you a straight answer.
Where we work
- Heating and cooling coils
- Filter sections
- Drain trays
- Internal panels
- Dampers and louvres

AHU cleaning for kitchens and businesses in Ravenstone
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. The work covers internal panels, dampers and louvres and heating and cooling coils, and common reasons people get in touch are dirty fans and fan housings and plant that needs cleaning after a refit.
Work in a small place like Ravenstone starts with agreeing access and timings.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey, before we quote.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
When to call us in Ravenstone
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Signs it’s time to call us include:
- Air handling units never cleaned inside
- Coils clogged with dust and debris
- Plant that needs cleaning after a refit
- Drain trays holding standing water
In Ravenstone, supply and extract ducts are cleaned along with the units that serve them.
What your quote should include
- Whether they recommend a next date
- What records you will receive afterwards
- Proof of insurance
- When they can work, and whether that’s outside your opening hours
Landlords, agents and facilities managers
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
We also work for facilities teams across offices, schools and healthcare in Ravenstone and across Milton Keynes. Work can be phased by floor, building or site around the people who use them.
What happens if it’s left?
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. In a small place like Ravenstone, a system that fails can take a site out of use.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before any work starts.
