Hertfordshire · Air handling unit cleaning
Babbs Green AHU cleaning
For cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Babbs Green, one call is all it takes, from survey to sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Filters that are clogged or overdue
- Dirty fans and fan housings
- Condensate trays that will not empty
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Report musty smells from the vents straight away
- Keep filter changes on time and recorded
- Book the next check in line with the report
- Store the TR19 paperwork where auditors can find it
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
AHU cleaning in Babbs Green
We clean air handling units for buildings in Babbs Green and across Hertfordshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers filter sections, dampers and louvres and drain trays, and people most often call us about rooms that smell stuffy when the system runs and coils clogged with dust and debris.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
A written report with photos follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. Out of sight is the usual reason a rural system goes too long without attention.
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.

How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. For a village or hamlet like Babbs Green, tell us about narrow lanes, gates and parking when you book.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
How to prepare
- Clear loose items from the work area
- Have your last certificate or report to hand
- Make sure equipment near the work can be switched off and left to cool
Getting a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.

Fixed quotes for AHU cleaning in Babbs Green
A fixed price needs a few facts first. We check:
- The number of sites or systems
- Site requirements such as sign-in and permits
- Access, including roofs, risers and ceiling voids
- Where the site is and how we reach it
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before work begins.
Helping us quote
To help us quote quickly, please include:
- Wide pictures of the system and the area around it
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
- Your opening hours and when the area is out of use
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
How the job changes from site to site
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
For landlords and multi-site operators
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
