AHU cleaning in South Willesborough, 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. The work covers dampers and louvres, supply and extract fans and drain trays, and the jobs we see most are dirty filters cutting the airflow and rooms that smell stuffy when the system runs.
Visits to a place like South Willesborough are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Your questions about AHU cleaning in South Willesborough
Is South Willesborough within the area you cover?
Yes, South Willesborough is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Can the work in South Willesborough be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
How long does an AHU clean take?
The work takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, so phone us on 0345 646 2711 or use the quote form to talk it through.
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.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply call 0345 646 2711, or send details by email.
What AHU cleaning can’t fix
In fairness, some problems need a different fix:
- Controls and BMS settings that run the unit
- Breakdowns that need a mechanical engineer
- Airflow problems caused by the system’s design
If you’re not sure, just call us on 0345 646 2711, or email photos and we’ll give you a straight answer before booking.
What the work covers
- Drain trays

For landlords and multi-site operators
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
How it works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes half a day to a full day per unit, with large plant planned over several shifts. In a place like South Willesborough, we fit the visit around your hours.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any parking or loading restrictions
How to get a quote
To help us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or send us an email.

Why deal with it now?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. You choose the date of a planned visit, and a breakdown never asks.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before any work starts.

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Make sure the unit’s access doors open easily
- Look at the condensate drain whenever the unit is serviced
- Report musty smells from the vents straight away
- Book the next check in line with the report
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
