AHU cleaning for kitchens and businesses in Down Street
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you have units that have only ever had filter changes and air handling units with blocked filters, we can help.
Somewhere as small as Down Street, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Different parts, different methods
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.

Do you need AHU cleaning in Down Street?
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
The symptoms we are asked about most include:
- Rooms that smell stuffy when the system runs
- Debris and leaves in the fresh air intake
- Air handling units with blocked filters
- Plant that has been serviced but not cleaned
For schools like Fletching Church of England Primary School, the holidays are the usual time to inspect and clean ventilation.
Before booking anyone
- Whether the figure could change on the day
- When they can work, and whether that’s outside your opening hours
- Whether inaccessible sections are listed on the report
- What records you’ll receive afterwards
Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
What affects the quote in Down Street
We do not publish a price list, because sites vary so much. What we look at:
- How big the system is
- Working hours and out-of-hours timing
- Parking and loading at the site
- Site requirements such as sign-in and permits
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, ring 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Any access panels or hatches you can see
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
- Wide photos of the system and the area around it
To get a fixed quote, call us on 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We usually come back within one working day.
What AHU cleaning can’t fix
In fairness, some problems need a different fix:
- Dirty ducts beyond the unit itself
- Damaged coils beyond cleaning
- Breakdowns that need a mechanical engineer
If in doubt, ring 0345 646 2711 or email us and we will say what we think before booking.
What the work covers
- Internal panels
- Supply and extract fans
- Filter sections
- Heating and cooling coils
- Drain trays
- Dampers and louvres
Why act early in Down Street
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. Somewhere as small as Down Street, losing a kitchen or building to a fault is felt by everyone who uses it.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before we start.

How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. The timing of a visit to Down Street is set by you, and the travel is our side of the planning.
- We look at the unit and the plant area during the survey.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Let us know about parking and loading
- Mention any locked doors, roof access or ceiling voids
- Let us know when the site is closed or quiet
Getting a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
