Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
The symptoms we’re asked about most are:
- Plant that has been serviced but not cleaned
- Blocked condensate drains and slimy trays
- Air handling units with blocked filters
- Coils clogged with dust and debris
Around Great Bardfield, as anywhere, ventilation cleaning begins with an inspection.

AHU cleaning for kitchens and businesses in Great Bardfield
We clean air handling units for buildings in Great Bardfield and across Essex, 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 internal panels, heating and cooling coils and dampers and louvres, and the jobs we see most are air handling units never cleaned inside and condensate trays that won’t empty.
Somewhere as small as Great Bardfield, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Look at the condensate drain whenever the unit is serviced
- Keep the certificate and photo report with the plant records
- Watch for drips or damp patches near the plant
- Do not store bins or materials near the intake
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Keep the area around the intake clear. What’s near the intake ends up in the unit.

Landlords, agents and facilities managers

What the work involves, part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Great Bardfield: your questions answered
Can a school’s ventilation in Great Bardfield be done out of term time?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Great Bardfield. Booking early in the term gives the best choice of holiday dates.
Do you work in villages like Great Bardfield?
Yes, we work in villages as well as towns, and Great Bardfield is covered. Just mention lanes, gates or anything else about the site when you book.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How much does AHU cleaning cost in Great Bardfield?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
How do you keep the site clean during the work?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Do you work evenings or weekends?
Yes. We work evenings, overnight and weekends, so the building keeps running in the day.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Each site gets its own report and photos.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.
What affects the cost of AHU cleaning
The survey tells us what the work involves. The main factors are:
- The size of the system
- Whether several sites go on one quote
- The condition of the system
- Travel, parking and unloading
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Your opening hours and when the area is out of use
- Problems your staff have spotted
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Photos showing the whole system and its surroundings
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Then call us on 0345 646 2711 or send us an email.
How it works
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. A few pictures of the system help us make the most of a visit to a place like Great Bardfield.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Let us know when the site is closed or quiet
- Mention any locked doors, roof access or ceiling voids
- Clear loose items from the work area
