How we handle AHU cleaning in Durley Street
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. If you’re dealing with plant that has been serviced but not cleaned and dirty fans and fan housings, we can help, from dampers and louvres, drain trays and filter sections onwards.
In a village or hamlet like Durley Street, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

When something else is needed
AHU cleaning cannot fix everything, and we will tell you before work begins. It does not solve:
- The supply and extract ducts, quoted separately
- Coils that are corroded or leaking and need replacing
- Problems with the unit’s controls or sensors
If in doubt, phone us on 0345 646 2711 or send us an email and we will say what we think.
Where we work
- Internal panels
- Heating and cooling coils
- Drain trays
- Filter sections
- Dampers and louvres
- Supply and extract fans
Part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with photos.
Aftercare tips
Simple habits between visits make a real difference. We recommend:
- Don’t store bins or materials near the intake
- Plan the next inspection before the last report gets filed away
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.

What your team can do, and what needs us
Staff cleaning doesn’t 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 they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
The process
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes from a few hours for a compact unit to a day or more for a large one, and the area is cleaned down before we leave. Rural roads and tight entrances are worth telling us about before a visit to Durley Street.
- 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.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Agree a time when the area can be out of use
- Mention any parking or loading restrictions
- Clear loose items from the work area

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Advice
When to call us in Durley Street
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Durley Street, that’s air they breathe for hours at a time.
Any of these means the system needs a check-up:
- Air handling units due a clean after building work
- Air handling units never cleaned inside
- Stale or musty smells from the ventilation
- Intake sections clogged with outdoor debris
If you manage a school such as Wyvern Technology College, ventilation cleaning is best booked for the holidays.
What to look for in a quote
- Whether inaccessible sections are listed on the report
- Whether they’re fully insured
