AHU cleaning in Southfields, done properly
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. If you are dealing with coils clogged with dust and debris and air handling units due a clean after building work, we can put it right, from internal panels, filter sections and dampers and louvres onwards.
For a building in or near Southfields, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Why deal with it now?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. Somewhere as small as Southfields, losing a kitchen or building to a fault is felt by everyone who uses it.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What you get with us
- We diagnose before we treat
- Fully insured
- CHAS and SafeContractor accredited, with ISO 9001
- In business since 2009
What the work involves, part by part
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Southfields: your questions answered
Can the work in Southfields be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. The work in Southfields can fit around your hours. Let us know the hours you are closed and we will book within them.
Do you work in villages like Southfields?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
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. Where we can’t see enough, we arrange a survey.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then phone us on 0345 646 2711, or email photos.
How long does it take to clean an air handling unit?
As a guide, it takes a single shift for a typical unit, longer for large or heavily soiled ones. We plan the shutdown around that, including evenings or weekends.
What AHU cleaning can’t fix
Not every problem is solved by AHU cleaning, and we’ll tell you before any work starts. It won’t put right:
- Problems with the unit’s controls or sensors
- Mechanical faults with motors, belts or bearings
- Coils that are corroded or leaking and need replacing
If in doubt, ring 0345 646 2711, or send details by email and we will say what we think before you book.

Signs you need AHU cleaning in Southfields
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
If you notice any of these, it’s worth a diagnosis:
- Intake sections clogged with outdoor debris
- Air handling units with blocked filters
- Drain trays holding standing water
- Fan sections that haven’t been cleaned in years
Healthcare buildings such as Orsett Hospital, about 1.1 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Southfields, yours matters too.
What to look for in a quote
- How they set the interval to the next visit
- Whether VAT is included
- What insurance they carry
- How areas they can’t reach will be recorded
What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes from a few hours for a compact unit to a day or more for a large one. Somewhere as small as Southfields, the date and timings are agreed with you well before the day.
- 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, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Clear loose items from the work area
- Tell us about site rules, permits or sign-in
Ask for a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.

How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether it’s a one-off visit or part of a schedule
- The number of sites or systems
- Working hours and out-of-hours timing
- The condition we find in the survey
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before any work starts.
What we need to know
Many jobs can be priced from photos and some basics. Useful things to send:
- The postcode and the type of business
- A few general shots of the system
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use

What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
