AHU cleaning for sites in Barnes

AHU cleaning for kitchens and businesses in Barnes

No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. The work covers dampers and louvres, internal panels and supply and extract fans, and people most often call us about intake sections clogged with outdoor debris and plant that needs cleaning after a refit.

London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. In a building in Barnes, dust and debris build up in the units and ductwork over time.

Good records are part of the job. You get a written report with photos after each visit, 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 to hand when an insurer or inspector asks.

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. Cleaning restores the open path through the fins.

Drain trays

The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.

Common questions in Barnes

Can you work in Barnes outside opening hours?

Yes, out-of-hours work is a big part of what we do. It means the site in Barnes keeps running as normal. When you give us a ring on 0345 646 2711 or email us, mention when the site is quiet.

Does London parking affect a job in Barnes?

Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. If the building has a loading slot system, we will book into it.

How much does AHU cleaning cost in Barnes?

Every site is different, so each gets its own fixed quote. To get one, phone us on 0345 646 2711, or email photos and tell us about the site and its opening hours.

Can one contract cover all our sites?

Yes. Tell us the addresses and what each needs and you will get one fixed quote.

Do you need to switch the unit off?

Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.

Do you repair air handling units?

We clean the unit and flag faults rather than repair them, with pictures where it helps.

Do you work in Barnes?

Yes. Our area takes in London and the counties of South East England, and that includes Barnes.

Can you quote from pictures?

Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.

When to call us in Barnes

An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.

Common reasons sites call us are:

  • Air handling units with blocked filters
  • Rooms that smell stuffy when the system runs
  • Air handling units due a clean after building work
  • Intake sections clogged with outdoor debris

Healthcare ventilation, from large hospitals like Barnes Hospital (about 0.7 miles south-west) to small clinics, depends on clean filters, coils and ducts.

What to look for in a quote

  • What paperwork you get at the end
  • What’s included in the scope, part by part
  • Whether the price is fixed
  • Whether the work can be done while the site is closed

What AHU cleaning can’t fix

Not every problem is solved by AHU cleaning, and we’d rather say so up front. It does not solve:

  • Leaking heating or cooling coils
  • Ventilation that was badly designed in the first place
  • Dirty ducts beyond the unit itself

Not sure which it is? You can call 0345 646 2711, or email photos and we will tell you honestly before booking.

Parts of the system we cover

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

AHU cleaning in Barnes: local notes

The FSA’s food hygiene register lists about 33 schools, colleges and universities, about 55 hospitals, care homes and childcare premises and about 11 hotels and B&Bs with registered kitchens or food service across Barnes and its immediate surroundings (about a mile and a half). Where buildings like these have air handling units, filters, coils and drain trays need regular attention. In London, ventilation plant is often on the roof or below ground, so the work is normally done out of hours. The nearest hospital to Barnes is Barnes Hospital, about 0.7 miles south-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.

Workplaces around Barnes Bridge station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. For schools like St Osmund's Catholic Primary School, the holidays are the usual time to inspect and clean ventilation.

Multi-site and managed buildings

We also work for facilities teams across offices, schools and healthcare in Barnes and across Greater London. Work can be phased by floor, building or site around the people who use them.

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 the report can go to both.

How the visit works

There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Before any visit in Barnes, we agree where the van can stop and how equipment reaches the system.

  1. We agree a shutdown window that suits the building.
  2. We take before pictures of each section of the unit.
  3. We work through the unit from the intake to the outlet.
  4. We finish with the fan section and the drain tray.
  5. After pictures are taken and the certificate issued.

Getting ready for the visit

  • Let us know when the site is closed or quiet
  • Clear the space around the work
  • Mention any sign-in, permit or induction we need

Getting a quote

Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or drop us a line.

Advice

What staff can safely do

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.

Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Keeping the system healthy

How long the results last depends on use and care. We suggest:

  • Look at the condensate drain whenever the unit is serviced
  • Report stiff or damaged access doors
  • Flag stale or damp smells in the supply air
  • File each AHU report in the maintenance log

The report suggests a date for the next inspection or clean, 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.

Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
