How we handle AHU cleaning in Fordham
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. We are often asked to deal with plant that has been serviced but not cleaned and leaves and litter drawn into the unit, on dampers and louvres, supply and extract fans and drain trays.
In a village or hamlet like Fordham, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Nothing is signed off by word of mouth: 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. Any parts we couldn’t reach are recorded on it too.

What we do, step by step
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. Pictures of the system and its access let us plan the work in Fordham before we set off.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Find the previous report, if there is one
- Let us know about parking and loading

Do you need AHU cleaning in Fordham?
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and slime and smells soon follow.
Common reasons sites call us are:
- Plant that needs cleaning after a refit
- Dirty coils holding back the airflow
- Blocked condensate drains and slimy trays
- Dirty fans and fan housings
Around Fordham, as anywhere, ventilation cleaning begins with an inspection.

Fordham: your questions answered
Can you work in Fordham outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Fordham doesn’t have to lose a day’s trading. Just call 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Do you work in villages like Fordham?
Yes, we work in villages as well as towns, and Fordham is covered. Photos of the system and directions to the site help us plan the visit.
How much does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, give us a ring on 0345 646 2711, or email photos and tell us about the site and its opening hours.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
What if parts of the system can’t be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.

What else we do in Fordham
Part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.
What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Why deal with it now?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. Rural sites cannot always move to another kitchen or room when something fails.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, ring 0345 646 2711 or email us for straight advice and a fixed quote.

Managing agents and facilities teams in Fordham
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- Any permits to work or inductions
- The number of sites or systems
- What state the system is in
- Whether it’s a one-off visit or part of a schedule
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- When the site is open and when it’s quiet
- Wide photos of the system and the area around it
- Your last certificate, test record or report
- The roof, plant room or outside wall the system runs to
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 photos, get a survey first. Either way, you get a fixed price before we start.
