AHU cleaning for kitchens and businesses in Jordans
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. Typical jobs include intake sections clogged with outdoor debris and odours coming through the supply air, on internal panels, drain trays and supply and extract fans.
For a building in or near Jordans, access is agreed in advance and the visit is planned around the journey.
Duct Doctor has 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.

Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
What happens on the day
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Seeing the system in photos first means the trip to Jordans can be planned properly.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To start, call 0345 646 2711, or send details by email.
Advice
What affects the cost of AHU cleaning
Your quote is based on your site. We take into account:
- Whether it’s a one-off visit or part of a schedule
- The condition we find in the survey
- Whether we need access equipment or extra panels
- When the work can happen, such as evenings, overnight or weekends
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711, or send details by email, and we’ll talk you through it.
Helping us quote
To help us quote quickly, send us:
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
- Photos showing the whole system and its surroundings
- Where the site is and what kind of site it is
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 we start.
What happens if it’s left?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, ready to show anyone who asks. In a small place like Jordans, a system that fails can take a site out of use.
What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.

Part by part
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.

Your questions about AHU cleaning in Jordans
Do you do school ventilation cleaning in Jordans in the summer holidays?
Yes, out-of-term visits are normal for schools. There are about 7 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Jordans. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you get to a site in Jordans?
Yes, Jordans is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can you clean the AHU out of hours?
Yes. The clean is planned around when the unit can be switched off. Healthcare and care settings are planned with staff.
Is there a survey before the work?
Yes. We always survey first, either from pictures and details you send or on a site visit. A fixed quote follows.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Can you price the work without visiting?
Typically, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we usually come back within one working day. Some sites still need a visit, and we will say so.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and leave the area clean.
How long does an AHU clean take?
It takes half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Clear leaves and litter away from the intake
- Store the TR19 paperwork where auditors can find it
- Report musty smells from the vents straight away
- Note any water around the unit or leaks below it
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Do you need AHU cleaning in Jordans?
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
If you notice any of these, it’s worth a diagnosis:
- Filters that are clogged or overdue
- Air handling units never cleaned inside
- Dust built up on fan impellers
- Dust-coated heating and cooling coils
If you manage offices or shops near Seer Green & Jordans station, their ventilation can be inspected and cleaned out of hours.
