About our AHU cleaning in Addington

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. If you are dealing with dirty filters cutting the airflow and intake sections clogged with outdoor debris, we can help, from supply and extract fans, filter sections and drain trays onwards.

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

The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

For landlords and multi-site operators

Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.

We work for landlords, managing agents and facilities managers as well as the people running the site. 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 the work involves, part by part

Rooftop and plant room units

Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.

Internal casing and panels

Dust settles on every internal surface of the unit. We clean each section from intake to discharge.

Addington: your questions answered

Can you come to Addington after we close?

Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Addington needn’t be disturbed. Tell us your opening hours when you ask for a quote.

Can you clean school ventilation in Addington during the holidays?

Yes, holiday work suits schools best. Around Addington, the Food Standards Agency lists about 18 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.

How much does AHU cleaning cost in Addington?

Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, typically ready within one working day.

Will the ventilation be off while you clean?

Yes, for the time we are working on it. We can work evenings, overnight or at weekends so the building is not left without ventilation when it’s busy.

Can you come out in an emergency?

Yes. Our emergency line runs 24/7, for problems that can’t wait. Call us any time and explain what’s happened.

How often should an air handling unit be cleaned?

There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.

Do you cover Addington?

Yes. We cover Addington and across Greater London, within our South East and London area. To book, give us a ring on 0345 646 2711 or drop us a line.

How long does an AHU clean take?

Expect it to take anything from half a day for one small unit to several shifts for a plant room full of them. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.

How the visit works

Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes one overnight shift for many single units, with bigger plant phased. For a job in Addington, tell us about loading bays, permits, lifts and roof access when you book.

  1. We start with a survey of the unit and a fixed quote for the work.
  2. With your site team, the unit is switched off and isolated, then the area around it 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. A TR19® certificate and photo report follow the clean.

Getting ready for the visit

  • Mention any sign-in, permit or induction we need
  • Arrange a key holder or contact on site
  • Find the previous report, if there is one

AHU cleaning in Addington: local notes

Food Standards Agency data includes about 18 schools, colleges and universities and about 36 caring premises (care homes, nurseries and hospitals) in and around Addington, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 1.6 miles north of Addington is National Psychosis Unit, 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. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot.

Healthcare buildings such as National Psychosis Unit, about 1.6 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Addington, yours matters too.

When to call us in Addington

Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Addington, that’s air they breathe for hours at a time.

The symptoms we are asked about most include:

  • Air handling units due a clean after building work
  • Dirty coils holding back the airflow
  • Dirty filters cutting the airflow
  • Odours coming through the supply air

Wherever a school like Applegarth Academy has ducted ventilation, a half-term visit keeps the work out of lesson time.

Questions to ask before you book

  • When the next visit should be, and why
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • Whether a survey comes first
  • Whether they’re fully insured

Choosing a duct cleaning contractor

Aftercare tips

Think of this as the after-treatment advice, short and simple:

  • Note any water around the unit or leaks below it
  • Stick to the filter change plan
  • Store the TR19 paperwork where auditors can find it
  • Diary the inspection date recommended in the report

The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.

Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.

Staff cleaning versus specialist work

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.

A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

What AHU cleaning cannot fix

We’d rather tell you now than book work that won’t help, so these are the things it will not cover:

  • Airflow problems caused by the system’s design
  • Problems with the unit’s controls or sensors
  • The supply and extract ducts, quoted separately

If in doubt, ring 0345 646 2711, or email photos and we will say what we think before you book.

Parts of the system we cover

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