AHU cleaning across Astrope

Looking after it afterwards

Once we’ve finished, these simple steps help:

  • Keep the area around the fresh air intake clear
  • File each AHU report in the maintenance log
  • Book the next check in line with the report
  • Make sure condensate is draining away

The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.

Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.

AHU cleaning for kitchens and businesses in Astrope

Where a building in Astrope has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you’re dealing with units needing a clean before a new tenant or handover and dust built up on fan impellers, we can put it right, from supply and extract fans, filter sections and heating and cooling coils onwards.

Work in a small place like Astrope starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.

A written report with photos follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What the work involves, part by part

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.

Fans and fan sections

The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.

AHU cleaning in Astrope: local notes

Tindal Centre is the nearest hospital, about 4.2 miles west of Astrope. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.

How we price AHU cleaning

We quote each job individually. This is what makes a difference:

  • How many systems or sites are involved
  • What state the system is in
  • Site rules, permits and inductions
  • When the work can happen, such as evenings, overnight or weekends

Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.

What to send for a quote

We can often survey from pictures. The most useful are:

  • The times we could work without disrupting the site
  • Your last certificate, test record or report
  • The postcode and the type of business
  • How we’d reach plant on a roof or in a plant room

Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

When to call us in Astrope

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.

What we are most often called out for:

  • Filters that are clogged or overdue
  • Condensate trays that will not empty
  • Dirty coils holding back the airflow
  • Plant that needs cleaning after a refit

Healthcare buildings such as Tindal Centre, about 4.2 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Astrope, yours matters too.

Before you book anyone

  • If they look at the system before pricing
  • How they set the interval to the next visit
  • What paperwork you get at the end

How to choose an extract cleaning contractor

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 hidden parts of the system still need specialist attention.

Common questions in Astrope

Is AHU cleaning available in Astrope?

Yes. Our area runs across London and the South East, Astrope included. To start, ring 0345 646 2711, or email photos with a few pictures of the system.

Do you cover smaller places like Astrope?

Yes. Astrope is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Where does the waste go?

We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.

How long will the unit be out of action?

As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the shutdown around that, including evenings or weekends.

Do you survey before quoting?

Yes. Every job is surveyed first, either from photos and details you send or on a site visit. Then you get a fixed quote.

How do you keep the site clean during the work?

Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.

Will you repair the fan or motor?

The clean includes noting faults, but repairs sit with your maintenance contractor, with photos where it helps.

Do you offer maintenance contracts?

Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.

What we do, step by step

We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Astrope, the date and timings are agreed with you well before the day.

  1. We look at the unit and the plant area during the survey.
  2. The area is protected and the unit made safe.
  3. Each section is cleaned of dust, debris and slime.
  4. Coils and trays are cleaned and the condensate drain cleared.
  5. The unit is closed up and handed back, with a report to follow.

Preparing for the visit

  • Plan for cooking equipment or plant to be off before we arrive
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Mention any sign-in, permit or induction we need
