Signs you need AHU cleaning in Stansted Mountfitchet
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.
Any of these means the system needs a check-up:
- Drain trays holding standing water
- Plant that has been serviced but not cleaned
- Fan sections that haven’t been cleaned in years
- Air handling units with blocked filters
Workplaces around Stansted Mountfitchet station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

AHU cleaning in Stansted Mountfitchet
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you have blocked condensate drains and slimy trays and fan sections that haven’t been cleaned in years, we can help.
For a building near Stansted Mountfitchet, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
A written report with photos follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Your questions about AHU cleaning in Stansted Mountfitchet
Is Stansted Mountfitchet within the area you cover?
Yes. Stansted Mountfitchet is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Do you clean school ventilation in Stansted Mountfitchet in the holidays?
Yes. The holidays are the usual time for school work. There are about 8 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Stansted Mountfitchet. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
Do you have insurance?
Yes. Full insurance covers our work and have been trading since 2009.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Can you clean without disrupting the building?
Yes. The clean is planned around when the unit can be switched off. Healthcare and care settings are planned with staff.
What affects the quote in Stansted Mountfitchet
We do not publish a price list, because no two systems are the same. The quote depends on:
- How big the system is
- Working hours and out-of-hours timing
- Whether we need access equipment or extra panels
- What state the system is in
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before any work starts.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- Your opening hours and when the area is out of use
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
- The roof, plant room or outside wall the system runs to
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Different parts, different methods
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey, before we quote.
How it works
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes half a day to a full day per unit, with large plant planned over several shifts. In a place like Stansted Mountfitchet, we fit the visit around your hours.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Getting ready for the visit
- Clear the space around the work
- Plan for cooking equipment or plant to be off before we arrive
- Dig out any earlier paperwork for the system
Get a fixed quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before work begins.

In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
