How we handle AHU cleaning in Hadham Ford
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. 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. We’re often asked to deal with filters that are clogged or overdue and debris and leaves in the fresh air intake, across heating and cooling coils, dampers and louvres and filter sections.
For a building in or near Hadham Ford, access is agreed in advance and the visit is planned around the journey.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What a clean won’t put right
AHU cleaning can’t fix everything, and we’ll tell you before work begins. It won’t put right:
- Mechanical faults with motors, belts or bearings
- Leaking heating or cooling coils
- A system that’s undersized for the building
If in doubt, phone us on 0345 646 2711 or email us and we’ll say what we think before you book.
What we work on in Hadham Ford
- Filter sections
- Dampers and louvres
- Supply and extract fans
- Internal panels
- Drain trays
- Heating and cooling coils
Different parts, different methods
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
Fixed quotes for AHU cleaning in Hadham Ford
Your quote is based on your site. We take into account:
- The size of the system
- Working hours and out-of-hours timing
- Whether it’s a one-off visit or part of a schedule
- Whether several sites go on one quote
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Where the site is and what kind of site it is
- Your opening hours and when the area is out of use
- Wide pictures of the system and the area around it
- How we’d reach plant on a roof or in a plant room
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Why deal with it now?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Planning a trip to Hadham Ford ahead is easier for everyone than a rushed one.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, call us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.
Why us?
- Out-of-hours work and a 24/7 emergency line
- A single point of contact for sites across the South East and London
- CHAS, SafeContractor and ISO 9001
- Fixed quotes, typically within one working day
In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare in Hadham Ford and across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
What happens on the day
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Pictures of the system and its access let us plan the work in Hadham Ford before we set off.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Let us know when the site is closed or quiet
- Mention any locked doors, roof access or ceiling voids
- Let us know about permits to work or site inductions
How to get a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Questions from Hadham Ford
Do you do school ventilation cleaning in Hadham Ford in the summer holidays?
Yes, and it’s the easiest time to do it. Around Hadham Ford, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you cover smaller places like Hadham Ford?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
How much does AHU cleaning cost in Hadham Ford?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
How often should an air handling unit be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
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.
Can you clean without disrupting the building?
Yes, wherever it helps the building. Tell us when the unit can go off and we’ll work to that.
What if parts of the system can’t be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
