Air handling unit cleaning in West Hanningfield, Essex
Professional AHU cleaning in and around West Hanningfield, timed so the site keeps working and finished with a written report and photos.
- Drain trays holding standing water
- Plant that needs cleaning after a refit
- Filters that are clogged or overdue
What the work involves, part by part
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
How we handle AHU cleaning in West Hanningfield
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. The work covers dampers and louvres, heating and cooling coils and supply and extract fans, and people most often call us about intake sections clogged with outdoor debris and drain trays holding standing water.
Work in a small place like West Hanningfield starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Common problems we fix in West Hanningfield
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Signs it’s time to call us include:
- Dirty filters cutting the airflow
- Plant that has been serviced but not cleaned
- Stale or musty smells from the ventilation
- Air handling units due a clean after building work
For buildings in and around West Hanningfield, TR19® Air cleaning starts with an inspection.

Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Change filters on schedule and log each change
- Do not store bins or materials near the intake
- Keep the certificate and photo report with the plant records
- Flag stale or damp smells in the supply air
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

Landlords, agents and facilities managers

Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
What affects the cost of AHU cleaning
We do not publish a price list, because no two systems are the same. What we look at:

- The size of the system
- The times the site is available
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before work begins.
