AHU cleaning in Lower Morden

Ventilation in Lower Morden buildings

Food Standards Agency data includes about 23 schools, colleges and universities and about 32 hospitals, care homes and childcare premises within about 1.5 miles of central Lower Morden. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. Lower Morden’s nearest hospital, St. Anthony's Hospital, is about 0.6 miles south. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.

If you run a surgery, dental practice or care home near Lower Morden, clean ventilation matters as much to you as to a hospital like St. Anthony's Hospital (about 0.6 miles south). Classrooms and halls at schools such as Aragon Primary School are easiest to work in when pupils are away.

Lower Morden is about 2 miles north-west of Sutton, in Greater London.

AHU cleaning for kitchens and businesses in Lower Morden

An air handling unit is the heart of a building’s ventilation: 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. We’re often asked to deal with condensate trays that won’t empty and odours coming through the supply air, on drain trays, dampers and louvres and internal panels.

London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Lower Morden is normally planned out of hours. Parking and loading are agreed with the building in advance.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What we do, step by step

Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Night and weekend working is normal for us in London, and a site in Lower Morden is no exception.

  1. The survey covers the unit, its access and how it can be shut down.
  2. The area is protected and the unit made safe.
  3. Dirt and debris are removed from each section.
  4. Coils and trays are cleaned and the condensate drain cleared.
  5. The unit is closed up and handed back, with a report to follow.

How to prepare

  • Plan for cooking equipment or plant to be off before we arrive
  • Mention any parking or loading restrictions
  • Find the previous report, if there is one

Advice

Managing agents and facilities teams in Lower Morden

Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.

Your questions about AHU cleaning in Lower Morden

Do you do school ventilation cleaning in Lower Morden in the summer holidays?

Yes, and it’s the easiest time to do it. The FSA’s register shows about 23 schools and colleges with food registrations within roughly a mile and a half of Lower Morden. You can ring 0345 646 2711 or drop us a line with the dates the site is empty.

Is parking a problem for work in Lower Morden?

A loading bay, a visitor permit or off-street space near the site in Lower Morden makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit typically gets round them.

What types of premises do you cover?

All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.

Do you give a certificate after the clean?

Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.

What information do you need?

A short description and a few photos plus the address and your hours. We’ll ask for anything else we need.

How do you keep the site clean during the work?

We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.

How long does an AHU clean take?

Cleaning takes from a few hours for a compact unit to a day or more for a large one. Bigger units can be phased, and you can phone us on 0345 646 2711 or drop us a line to plan it.

Is there a survey before the work?

Yes. Photos often do the job, and larger or hidden systems get a visit.

Different parts, different methods

Drain trays

Older trays can corrode and start leaking. Their condition goes into the report with pictures so you can decide on any repairs.

Internal casing and panels

Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.

Aftercare tips

So the system stays in good health:

  • Diary the inspection date recommended in the report
  • Clear leaves and litter away from the intake
  • Report water on the plant room floor
  • Report stiff or damaged access doors

Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.

Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.

When something else is needed

An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:

  • Breakdowns that need a mechanical engineer
  • Dirty ducts beyond the unit itself
  • Building management system faults

Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we will tell you honestly.

What the work covers

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

Common problems we fix in Lower Morden

Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.

Keep an eye out for any of the following:

  • Air handling units with blocked filters
  • Air handling units never cleaned inside
  • Units needing a clean before a new tenant or handover
  • Debris and leaves in the fresh air intake

Workplaces around St Helier station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

Questions to ask before booking

  • What hours they’ll be on site
  • Whether the figure could change on the day
  • What’s included in the scope, part by part
  • How they set the interval to the next visit

Questions to ask before booking

What happens if it’s left?

Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. Leaving it on a busy London site only adds to the work.

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
