Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Facilities teams in offices, schools and healthcare sites book us too across Milton Keynes. Work can be phased by floor, building or site around the people who use them.
AHU cleaning in Little Horwood
Our AHU cleaning covers sites in Little Horwood and the rest of Milton Keynes, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you have condensate trays that won’t empty and odours coming through the supply air, we can put it right.
Work in a small place like Little Horwood starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Good records are part of the job. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. Rural roads and tight entrances are worth telling us about before a visit to Little Horwood.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Clear the space around the work
- Have your last certificate or report to hand
- Let us know how we reach the system, including roofs, risers and plant rooms

Where we work
- Filter sections
- Supply and extract fans
- Internal panels
- Dampers and louvres
- Heating and cooling coils
- Drain trays
What we’re called out for in Little Horwood
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Look out for any of the following:
- Dust built up on fan impellers
- Dirty coils holding back the airflow
- Units needing a clean before a new tenant or handover
- Units that have only ever had filter changes
Wherever a school like Sir Thomas Fremantle School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What your quote should include
- Whether the figure could change on the day
- What records you will receive afterwards
- Whether VAT is included
- Proof of accreditation you can verify
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Flag stale or damp smells in the supply air
- Keep filter changes on time and recorded
- File each AHU report in the maintenance log
- Diary the inspection date recommended in the report
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Change or clean filters on time. Once filters clog, dirt starts getting past them.

Different parts, different methods
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
Why deal with it now?
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Out of sight is the usual reason a rural system goes too long without attention.
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

Your questions about AHU cleaning in Little Horwood
Do you work at weekends in Little Horwood?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Little Horwood needn’t be disturbed. When you call 0345 646 2711, or email photos, mention when the site is quiet.
Is AHU cleaning available in Little Horwood?

How long does it take to clean an air handling unit?

Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with photos where it helps.
How much does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
