AHU cleaning in Fyfield, done properly
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. Typical jobs include dirty coils holding back the airflow and dirty filters cutting the airflow, across dampers and louvres, heating and cooling coils and supply and extract fans.
In a village or hamlet like Fyfield, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
A written report with photos follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What affects the quote in Fyfield
The survey tells us what the work involves. The main factors are:
- Where the site is and how we reach it
- The size of the system
- The times the site is available
- The number of sites or systems
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
- The postcode and the type of business
- When the site is open and when it’s quiet
Getting a quote does not take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
FAQs for Fyfield
Can you come to Fyfield after we close?
Yes, nights and weekends are routine for us. It means the site in Fyfield keeps running as normal. Just call us on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Is Fyfield within the area you cover?
Yes. Fyfield 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.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
How often should an air handling unit be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends to keep disruption down.
Is a quote from pictures possible?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
When it’s something else
We won’t sell you work that does not address the problem, so here are the limits:
- Damaged coils beyond cleaning
- A system that’s undersized for the building
- Problems with the unit’s controls or sensors
If you are not sure, just give us a ring on 0345 646 2711 or use the quote form and we will give you a straight answer before you book.

The process
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes anything from half a day for one small unit to several shifts for a plant room full of them. Seeing the system in photos first means the trip to Fyfield can be planned properly.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Let us know about parking and loading
- Allow time for equipment near the work to be turned off and cool down
- Clear the space around the work

How the job changes from site to site
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Common problems we fix in Fyfield
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Clients typically contact us after spotting something like this:
- Drain trays holding standing water
- Dirty coils holding back the airflow
- Rooms that smell stuffy when the system runs
- Filters that are clogged or overdue
If you run a surgery, dental practice or care home near Fyfield, clean ventilation matters as much to you as to a hospital like Abingdon Community Hospital (about 4 miles east).

Why it’s worth doing now in Fyfield
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. A fault that closes a site in a village like Fyfield affects everyone who depends on it.
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or drop us a line, and we will talk you through it.
