AHU cleaning for sites in Holborn

What happens on the day

Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a single shift for a typical unit, longer for large or heavily soiled ones. In Holborn, as across London, we normally work overnight or at weekends and hand the site back ready to open.

  1. We start with a survey of the unit and a fixed quote for the work.
  2. The unit is shut down with your site team and the area protected.
  3. We clean or change the filters as agreed, then clean the coils, fan and internal panels.
  4. We clean out the drain tray and make sure it drains.
  5. You get a TR19® certificate and a photo report.

Getting ready for the visit

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Clear the space around the work
  • Tell us where we can park and unload

Getting a quote

Getting a quote doesn’t take long. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

How we handle AHU cleaning in Holborn

All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. Common call-outs are for rooms that smell stuffy when the system runs and intake sections clogged with outdoor debris, on drain trays, supply and extract fans and heating and cooling coils.

London buildings tend to keep their plant on the roof or below ground, so work in Holborn is often done in the evening or at weekends. Loading and parking are planned with the building first.

Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Ventilation in Holborn buildings

Food Standards Agency data includes about 74 schools, colleges and universities, about 51 caring premises (care homes, nurseries and hospitals) and about 197 hotels and guest houses within 1.5 miles or so of the middle of Holborn. Busy, occupied buildings like these are where clean supply air matters most. About under half a mile west of Holborn is Royal London Hospital for Integrated Medicine, the nearest hospital. 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.

Classrooms and halls at schools such as St Alban's Church of England Primary School are easiest to work in when pupils are away. If you manage offices or shops near Farringdon station, their ventilation can be inspected and cleaned out of hours.

Common questions in Holborn

Can parking be tricky for a job in Holborn?

A loading bay, a visitor permit or off-street space near the site in Holborn makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.

Do you work at weekends in Holborn?

Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Holborn needn’t be disturbed. Let us know the hours you are closed and we will book within them.

How much does AHU cleaning cost?

There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.

Which kinds of sites do you work on?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.

How often do AHUs need cleaning?

It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.

Are you insured?

Yes. Duct Doctor is fully insured, and the details are available on request.

What information do you need?

The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.

What do you clean inside the unit?

Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.

Between visits

To keep the system working properly between visits:

  • Clear leaves and litter away from the intake
  • Keep filter changes on time and recorded
  • Flag stale or damp smells in the supply air
  • Diary the inspection date recommended in the report

Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.

Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.

Fixed quotes for AHU cleaning in Holborn

The diagnosis comes before the price. The main factors are:

  • The condition of the system
  • How big the system is
  • A single visit or a regular plan
  • Whether we need access equipment or extra panels

We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711 or email us, and we will talk you through it.

What we need to know

What to send for a quote:

  • When the site is open and when it’s quiet
  • Any previous report or certificate
  • The roof, plant room or outside wall the system runs to
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

What we’re called out for in Holborn

An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.

Most sites get in touch when they notice one of these:

  • Air handling units with blocked filters
  • Units that have only ever had filter changes
  • Units needing a clean before a new tenant or handover
  • Debris and leaves in the fresh air intake

Royal London Hospital for Integrated Medicine, about under half a mile west, is the nearest hospital to Holborn, and healthcare sites of every size need their supply air kept clean.

Comparing quotes

  • Whether they’re fully insured
  • Which accreditations they hold, and whether you can check them
  • Whether a written report and pictures are included
  • What happens if part of the system cannot be accessed

Choosing a duct cleaning contractor

When something else is needed

AHU cleaning cannot fix everything, and we’d rather say so up front. It will not put right:

  • The supply and extract ducts, quoted separately
  • Problems with the unit’s controls or sensors
  • A system that is undersized for the building

If in doubt, give us a ring on 0345 646 2711 or use the quote form and we’ll say what we think before you book.

What we work on in Holborn

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

Managing agents and facilities teams in Holborn

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.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.

What staff can safely do

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. Leave those to us.

Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
