How we handle AHU cleaning in Alperton

If the units serving a building in Alperton have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. If you are dealing with units needing a clean before a new tenant or handover and leaves and litter drawn into the unit, we can help.

Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Alperton, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.

Good records are part of the job. You get a written report with pictures after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

How it works

At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes one overnight shift for many single units, with bigger plant phased. Expect the work in Alperton to happen after your last customer leaves, not during trading.

  1. First we agree when the unit can be switched off, including evenings or weekends.
  2. Before cleaning, each section is photographed.
  3. Filters, coils and internal surfaces are cleaned from intake to discharge.
  4. We finish with the fan section and the drain tray.
  5. We take after pictures and issue the certificate and report.

Preparing for the visit

  • Let us know about permits to work or site inductions
  • Make sure equipment near the work can be switched off and left to cool
  • Let us know how we reach the system, including roofs, risers and plant rooms

What your team can do, and what needs us

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Common problems we fix in Alperton

Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.

Clients typically contact us when they notice one of these:

  • Fan sections that haven’t been cleaned in years
  • Blocked condensate drains and slimy trays
  • Air handling units due a clean after building work
  • Coils clogged with dust and debris

Healthcare buildings such as Central Middlesex Hospital, about 1.5 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Alperton, yours matters too.

Choosing a duct cleaning contractor

What a clean will not put right

Not every problem is solved by AHU cleaning, and we’ll tell you before work begins. It does not solve:

  • Coils that are corroded or leaking and need replacing
  • Breakdowns that need a mechanical engineer
  • The supply and extract ducts, quoted separately

If in doubt, call us on 0345 646 2711, or send details by email and we’ll say what we think.

Where we work

  • Internal panels
  • Heating and cooling coils
  • Drain trays
  • Filter sections
  • Supply and extract fans
  • Dampers and louvres

How the job changes from site to site

Heating and cooling coils

Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.

Internal casing and panels

We open each section through its doors and close them securely when we’re done, and check every one is shut.

For landlords and multi-site operators

Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

Keeping the system healthy

So the system stays in good health:

  • Flag stale or damp smells in the supply air
  • Stick to the filter change plan
  • Keep the area around the fresh air intake clear
  • Look at the condensate drain whenever the unit is serviced

The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.

Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.

Alperton buildings and their air

Food Standards Agency data includes about 32 schools, colleges and universities, about 75 care, childcare and hospital premises and about 8 hotels and B&Bs in Alperton and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. The nearest hospital to Alperton is Central Middlesex Hospital, about 1.5 miles south-east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. London plant rooms are often on roofs or in basements reached through occupied floors.

For workplaces around Wembley Central station with mechanical ventilation, cleaning can be done in the evening or at weekends. Classrooms and halls at schools such as Alperton Community School are easiest to work in when pupils are away.
