How we handle AHU cleaning in Fyfield
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. The work covers dampers and louvres, internal panels and heating and cooling coils, and common reasons people get in touch are blocked condensate drains and slimy trays and coils clogged with dust and debris.
Work in a small place like Fyfield starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so repairs can be planned.
What affects the quote in Fyfield
Sites vary more than people expect. What affects the quote:
- When the work can happen, such as evenings, overnight or weekends
- The condition of the system
- How many systems or sites are involved
- Where the site is and how we reach it
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What to send for a quote
Before you ask for a quote, gather:
- Wide pictures of the system and the area around it
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- The site address and the type of premises
If you need AHU cleaning in Fyfield, call us on 0345 646 2711 or send us an email. Let us know the site type and the opening hours, and send photos or your last report if you can. A fixed quote normally follows within one working day.
What happens on the day
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes from a few hours for a compact unit to a day or more for a large one. If the van will struggle with a lane or gateway near Fyfield, let us know and we’ll plan around it.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it 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.
- You get a TR19® certificate and a photo report.
Before we arrive
- Have your last certificate or report to hand
- Let us know about parking and loading
- Tell us the best time to work, such as after service or at a weekend

Related advice
Do you need AHU cleaning in Fyfield?
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.
Keep an eye out for these warning signs:
- Units that have only ever had filter changes
- Rooms that smell stuffy when the system runs
- Drain trays holding standing water
- Fan sections that haven’t been cleaned in years
In Fyfield, we look inside the system before deciding what needs cleaning.

What else we do in Fyfield
What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
FAQs for Fyfield
Do you offer AHU cleaning in Fyfield?
Yes. We work across London and the South East, and Fyfield is part of that. You can call us on 0345 646 2711 or email us and tell us what needs doing.
Can you come to Fyfield after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in Fyfield keeps running as normal. Tell us your opening hours when you ask for a quote.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
Does the AHU have to be shut down for cleaning?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
What about areas you can’t get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
Can you quote from pictures?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What AHU cleaning can’t fix
It’s worth knowing the limits before booking:
- A system that’s undersized for the building
- Problems with the unit’s controls or sensors
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can call us on 0345 646 2711 or send us an email and we will tell you honestly before booking.
