AHU cleaning in South Heath
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. Typical jobs include stale or musty smells from the ventilation and dirty coils holding back the airflow, across supply and extract fans, internal panels and dampers and louvres.
Work in a small place like South Heath starts with agreeing access and timings.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

FAQs for South Heath
Is South Heath in your area for AHU cleaning?
Yes, South Heath is covered. A fixed quote typically follows within one working day of the survey details.
Do you work in villages like South Heath?
Yes. South Heath is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
How long does it take to clean an air handling unit?
Expect it to take one overnight shift for many single units, with bigger plant phased. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
Can you clean without disrupting the building?
Yes, wherever it helps the building. Tell us when the unit can go off and we will work to that.
How do you protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.
What happens to the waste?
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.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
What staff can safely do
Your own staff can handle the daily basics: 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.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Why deal with it now?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Rural sites cannot always move to another kitchen or room when something fails.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before we start.

How the job changes from site to site
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Internal casing and panels
We open each section through its doors and close them securely when we are done before the unit is handed back.
Aftercare tips
Results last longer with the right care. We suggest:
- Stick to the filter change plan
- Make sure the unit’s access doors open easily
- Report water on the plant room floor
- Check the drain tray is emptying during routine visits
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
When it’s something else
To be straight with you, there are a few things this work will not fix:
- A system that is undersized for the building
- Building management system faults
- Breakdowns that need a mechanical engineer
If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think.
