AHU cleaning for kitchens and businesses in Hatford
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. If you are dealing with dust-coated heating and cooling coils and units needing a clean before a new tenant or handover, we can put it right.
In a village or hamlet like Hatford, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
A written report with pictures follows every 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.

Signs you need AHU cleaning in Hatford
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
It’s time to book a visit if you see:
- Blocked condensate drains and slimy trays
- Air handling units with blocked filters
- Odours coming through the supply air
- Units that have only ever had filter changes
School buildings such as Stanford in the Vale Church of England Primary School are usually done in the holidays, so classrooms aren’t disturbed.
Questions to ask before booking
- Whether they recommend a next date
- Whether inaccessible sections are listed on the report
- What records you will receive afterwards
- Whether a survey comes first
Leave it or put it right?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. Out of sight is the usual reason a rural system goes too long without attention.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.

Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Report water on the plant room floor
- Flag stale or damp smells in the supply air
- Report stiff or damaged access doors
- Clear leaves and litter away from the intake
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.

The process
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes half a day to a full day per unit, with large plant planned over several shifts. Pictures of the system and its access let us plan the work in Hatford before we set off.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Before we arrive
- Dig out any earlier paperwork for the system
- Mention any parking or loading restrictions
- Let us know how we reach the system, including roofs, risers and plant rooms
Ask for a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.
Advice
What affects the cost of AHU cleaning
Every site gets its own quote. This is what makes a difference:
- Travel, parking and unloading
- Site requirements such as sign-in and permits
- How big the system is
- A single visit or a regular plan
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before we start.
Asking for a quote
We can often survey from photos. The most useful are:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide photos of the system and the area around it
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, give us a ring on 0345 646 2711, or send details by email.

Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Drain trays
Older trays can corrode and start leaking. We record their condition with pictures so you can decide on any repairs.
