AHU cleaning for sites in Kidbrooke

About our AHU cleaning in Kidbrooke

Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. Common call-outs are for odours coming through the supply air and plant that needs cleaning after a refit, across internal panels, dampers and louvres and heating and cooling coils.

In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Kidbrooke is typically planned out of hours. Parking and loading are agreed with the building in advance.

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.

In-house cleaning or a specialist?

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.

What AHU cleaning looks like in Kidbrooke

The FSA’s food hygiene register lists about 49 schools, colleges and universities and about 54 hospitals, care homes and childcare premises with registered kitchens or food service within about 1.5 miles of central Kidbrooke. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. In London, ventilation plant is often on the roof or below ground, so the work is normally done out of hours. Kidbrooke’s nearest hospital, Brook General Hospital, is about 0.5 miles north-east. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

Hospitals such as Brook General Hospital (about 0.5 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Kidbrooke are no different. If you run an office near Kidbrooke station, its supply ductwork can gather dust for years before anyone looks inside.

Part by part

Internal casing and panels

The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.

Heating and cooling coils

Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.

Common problems we fix in Kidbrooke

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.

Any of these means the system needs a check-up:

  • Fan sections that haven’t been cleaned in years
  • Condensate trays that will not empty
  • Intake sections clogged with outdoor debris
  • Plant that has been serviced but not cleaned

For schools like Henwick Primary School, the holidays are the usual time to inspect and clean ventilation.

Questions to ask before you book

  • Whether they’re fully insured
  • Whether the quote is based on a survey or photos
  • Whether the figure could change on the day
  • Whether they recommend a next date

Questions to ask before you book

Between visits

Aftercare is simple, and it makes the next visit easier:

  • Keep the area around the fresh air intake clear
  • Diary the inspection date recommended in the report
  • Check the drain tray is emptying during routine visits
  • Keep filter changes on time and recorded

We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.

Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.

Why deal with it now?

If people in a building in Kidbrooke complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. London sites work long hours, and the longer a job is left, the bigger it gets.

Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

Why Kidbrooke businesses choose us

  • We are fully insured
  • Fixed quotes from a survey or photos
  • CHAS, SafeContractor and ISO 9001
  • Work around your opening hours, with 24/7 emergency cover

Kidbrooke: your questions answered

Is parking a problem for work in Kidbrooke?

Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.

Can you work in Kidbrooke outside opening hours?

Yes, we can come after you close and finish before you open. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.

Do you offer emergency callouts?

Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.

Do you give a certificate after the clean?

Yes, both a certificate and a report with pictures. The report also suggests when the unit should next be inspected.

What should I send you?

Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then call 0345 646 2711, or send details by email.

Can you clean the ducts connected to the AHU?

Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can quote for both.

What’s included in an AHU clean?

Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.

Which accreditations do you hold?

BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we are fully insured.

The process

A visit follows the same order every time: protect the area, make the system safe, carry out the AHU cleaning, tidy up and leave you the report. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. We fit London jobs around the building rather than the other way round, so a visit in Kidbrooke is normally out of hours.

  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. We take after photos and issue the certificate and report.

How to prepare

  • Tell us where we can park and unload
  • Clear loose items from the work area
  • Let us know how we reach the system, including roofs, risers and plant rooms

How to get a quote

The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Advice

What AHU cleaning cannot fix

In fairness, there are a few things this work won’t fix:

  • Leaking heating or cooling coils
  • The supply and extract ducts, quoted separately
  • Ventilation that was badly designed in the first place

If in doubt, give us a ring on 0345 646 2711 or use the quote form and we will say what we think.
