Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Keep the area around the fresh air intake clear
- Make sure condensate is draining away
- Store the TR19 paperwork where auditors can find it
- Keep filter changes on time and recorded
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
AHU cleaning in Wallend, done properly
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. 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 have dirty coils holding back the airflow and condensate trays that won’t empty, we can put it right, from dampers and louvres, drain trays and internal panels onwards.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Wallend.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Wallend simpler. London sites work long hours, and the longer a job is left, the bigger it gets.
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before we start.

What AHU cleaning looks like in Wallend
There are about 49 schools, colleges and universities, about 52 caring premises (care homes, nurseries and hospitals) and about 4 hotels and B&Bs on the FSA’s food hygiene register in and around Wallend, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Ventilation cleaning in London buildings is normally planned for evenings or weekends. Newham University Hospital is the nearest hospital, about 1.4 miles south-west of Wallend. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
Workplaces around Barking station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. School buildings such as Nelson Primary School are usually done in the holidays, so classrooms are not disturbed.

The nearest railway station is Barking station, roughly 0.9 miles north-east.

What staff can safely do
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.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
What we’re called out for in Wallend
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
Most sites get in touch after spotting something like this:
- Air handling units never cleaned inside
- Units needing a clean before a new tenant or handover
- Debris and leaves in the fresh air intake
- Dirty coils holding back the airflow
Healthcare ventilation, from large hospitals like Newham University Hospital (about 1.4 miles south-west) to small clinics, depends on clean filters, coils and ducts.

Wallend questions
What do you need to know about parking in Wallend?

Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
What if parts of the system can’t be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.

It leaves the site with us when we go. During the work, it’s contained to keep the area clean.

We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
Can you clean the ducts connected to the AHU?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
Different parts, different methods
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.
