AHU cleaning for kitchens and businesses in Northway
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. The work covers drain trays, filter sections and dampers and louvres, and the jobs we see most are dirty filters cutting the airflow and odours coming through the supply air.
Around a place like Northway, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Managing agents and facilities teams in Northway
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
What your team can do, and what needs us
Your own staff can handle the daily basics: 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, and that’s where we come in.
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. The inside of ducts and units needs a specialist.
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:
- Problems with the unit’s controls or sensors
- Breakdowns that need a mechanical engineer
- Ventilation that was badly designed in the first place
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly before you book.
What we work on in Northway
- Heating and cooling coils
- Internal panels
- Supply and extract fans
- Dampers and louvres
- Drain trays
- Filter sections
How the job changes from site to site
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Make sure condensate is draining away
- Diary the inspection date recommended in the report
- Note any water around the unit or leaks below it
- Keep inspection doors on the unit in good order
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
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 we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes one overnight shift for many single units, with bigger plant phased. In a smaller place like Northway, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Mention any locked doors, roof access or ceiling voids
- Let us know about permits to work or site inductions
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Advice
What we’re called out for in Northway
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
Keep an eye out for these warning signs:
- Dust built up on fan impellers
- Filters that are clogged or overdue
- Plant that needs cleaning after a refit
- Stale or musty smells from the ventilation
School buildings such as New Marston Primary School are normally done in the holidays, so classrooms aren’t disturbed.
What your quote should include
- Whether the figure could change on the day
- Whether the quote is based on a survey or pictures
- How VAT is shown on the quote
- Whether inaccessible sections are listed on the report
