How we handle AHU cleaning in Newington Green
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. We are often asked to deal with air handling units with blocked filters and units needing a clean before a new tenant or handover, across heating and cooling coils, supply and extract fans and filter sections.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Newington Green.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Part by part
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey, before we quote.
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Common problems we fix in Newington Green
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Clients typically contact us after spotting one of these:
- Fan sections that haven’t been cleaned in years
- Air handling units with blocked filters
- Units needing a clean before a new tenant or handover
- Plant that has been serviced but not cleaned
School buildings such as Newington Green Primary School are typically done in the holidays, so classrooms aren’t disturbed.
Before you book anyone
- Which accreditations they hold, and whether you can check them
- Whether they’re fully insured
- What paperwork you get at the end
- If they look at the system before pricing
Keeping the system healthy
Results last longer with the right care. We suggest:
- Look at the condensate drain whenever the unit is serviced
- Keep inspection doors on the unit in good order
- Keep filter changes on time and recorded
- Do not store bins or materials near the intake
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in Newington Green and across Greater London. Larger estates can be phased building by building around the people who use them.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Security desks and permits-to-work are routine in London, so let us know what your building in Newington Green needs from us.
- We start with a survey of the unit and a fixed quote for the work.
- 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.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Let us know about parking and loading
- Plan for cooking equipment or plant to be off before we arrive
Get a fixed quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
Advice
Ventilation in Newington Green buildings
Going by the FSA’s register, there are about 42 schools, colleges and universities, about 63 care, childcare and hospital premises and about 12 hotels, B&Bs and guest houses serving food within about 1.5 miles of central Newington Green. Busy, occupied buildings like these are where clean supply air matters most. For Newington Green, the closest hospital is German Hospital, roughly 0.8 miles east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. London plant rooms are often on roofs or in basements reached through occupied floors.
If you run a surgery, dental practice or care home near Newington Green, clean ventilation matters as much to you as to a hospital like German Hospital (about 0.8 miles east). If you manage offices or shops near Canonbury station, their ventilation can be inspected and cleaned out of hours.

When it’s something else
