AHU cleaning across Golders Green

AHU cleaning in Golders Green, done properly

Our AHU cleaning covers sites in Golders Green and the rest of Greater London, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you’re dealing with rooms that smell stuffy when the system runs and air handling units with blocked filters, we can help, from dampers and louvres, filter sections and heating and cooling coils onwards.

London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. In Golders Green, as elsewhere, cleaning starts with an inspection of what’s there.

The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

AHU cleaning around Golders Green

The FSA’s food hygiene register lists about 50 schools, colleges and universities, about 41 hospitals, care homes and childcare premises and about 13 hotels, B&Bs and guest houses with registered kitchens or food service within roughly a mile and a half of the centre of Golders Green. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. New End Hospital is the nearest hospital, about 1.4 miles south-east of Golders Green. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first.

Healthcare ventilation, from large hospitals like New End Hospital (about 1.4 miles south-east) to small clinics, depends on clean filters, coils and ducts.

Fixed quotes for AHU cleaning in Golders Green

Before we fix a price, we need to know a few things. We look at:

  • Whether we need access equipment or extra panels
  • Working hours and out-of-hours timing
  • Whether it’s a one-off visit or part of a schedule
  • The scale of the work

Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.

What we need to know

A few details help us quote accurately. With your enquiry, please include:

  • Where the site is and what kind of site it is
  • The roof, plant room or outside wall the system runs to
  • The paperwork from the last visit, if you have it
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

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.

For landlords and multi-site operators

Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.

How the job changes from site to site

Internal casing and panels

Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.

Heating and cooling coils

Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.

Your questions about AHU cleaning in Golders Green

Can you work in Golders Green outside opening hours?

Yes, nights and weekends are routine for us. Your customers, staff or residents in Golders Green needn’t be disturbed. Your opening times are the first thing we ask for.

Can a school’s ventilation in Golders Green be done out of term time?

Yes. Half-terms and the summer break are the natural time for school work. There are about 50 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Golders Green. Send us your term dates when you call us on 0345 646 2711, or send details by email, and we’ll fit the work in.

Do you cover Golders Green?

Yes. Our area takes in London and the counties of South East England, Golders Green included.

Is there a report after cleaning?

Yes. You get a TR19® certificate plus before and after photos. Keep them in the maintenance log.

Will the ventilation be off while you clean?

Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.

How often should an air handling unit be cleaned?

Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.

Do you have insurance?

Yes. We are fully insured, and we can share the details when you need them.

Will you repair the fan or motor?

Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded for your maintenance team to follow up.

Do you need AHU cleaning in Golders Green?

Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that’s where slime and odours start.

Most sites get in touch when they notice something like this:

  • Dirty coils holding back the airflow
  • Intake sections clogged with outdoor debris
  • Fan sections that haven’t been cleaned in years
  • Plant that has been serviced but not cleaned

If you manage a school such as Rimon Jewish Primary School, ventilation cleaning is best booked for the holidays.

Our hiring checklist

Why deal with it now?

Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. In a London building, a problem in a duct, damper or fan rarely stays in one unit.

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 will explain each part.

Why choose Duct Doctor in Golders Green

See our cost guide and how to check a contractor.

When it’s something else

We will not sell you work that does not address the problem, so these are the things it won’t cover:

  • Controls and BMS settings that run the unit
  • Mechanical faults with motors, belts or bearings
  • Ductwork downstream of the unit, which is a separate clean

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

Parts of the system we cover

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

How it works

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. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Golders Green.

  1. We agree a shutdown window that suits the building.
  2. Before cleaning, each section is photographed.
  3. We work through the unit from the intake to the outlet.
  4. The fan and drain tray are cleaned and the drain checked.
  5. After photos are taken and the certificate issued.

Preparing for the visit

  • Let us know about permits to work or site inductions
  • Tell us where we can park and unload
  • Mention any locked doors, roof access or ceiling voids
