AHU cleaning in Coombe, done properly

If the units serving a building in Coombe have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. If you are dealing with intake sections clogged with outdoor debris and dirty filters cutting the airflow, we can put it right.

In a village or hamlet like Coombe, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.

Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Common problems we fix in Coombe

Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, a little more each month.

Common reasons sites call us include:

  • Fan sections that haven’t been cleaned in years
  • Drain trays holding standing water
  • Plant that needs cleaning after a refit
  • Debris and leaves in the fresh air intake

Healthcare buildings such as Stoke Mandeville Hospital, about 3.5 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Coombe, yours matters too.

Common questions in Coombe

Do you work overnight in Coombe?

Yes, we can come after you close and finish before you open. It means the site in Coombe keeps running as normal. Your opening times are the first thing we ask for.

Is Coombe in your area for AHU cleaning?

Yes. We work across London and the South East, and Coombe is part of that. Just call 0345 646 2711 or use the quote form with a few details of the site.

Do you survey before quoting?

Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.

How do you protect the area?

By covering it before any work starts. We keep the work contained and leave the area clean.

What does AHU cleaning cost?

It depends on the site, so we quote each one individually. For a quote, ring 0345 646 2711, or email photos and tell us about the site and its opening hours.

How often do AHUs need cleaning?

It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.

Do you work with multi-site operators?

Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.

What happens to the waste?

It leaves the site with us when we go. While we work, it’s kept contained so the area stays clean.

What affects the cost of AHU cleaning

There’s no set price list, because no two systems are the same. The quote depends on:

  • The condition we find in the survey
  • The times the site is available
  • Site rules, permits and inductions
  • Parking and loading at the site

What you pay reflects the actual work. That is why we survey first, from pictures or on site, and the price is agreed before any work starts.

Helping us quote

Photos let us diagnose from a distance. The most useful are:

  • Wide photos of the system and the area around it
  • Any symptoms, from odd noises to smells or leaks
  • The times we could work without disrupting the site
  • The site address and the type of premises

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

Keeping the system healthy

A little care between visits keeps the system in better shape. We recommend:

  • Diary the inspection date recommended in the report
  • File each AHU report in the maintenance log
  • Look at the condensate drain whenever the unit is serviced
  • Keep inspection doors on the unit in good order

We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.

Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.

Landlords, agents and facilities managers

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.

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 to a regular schedule.

When something else is needed

An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:

  • Building management system faults
  • Airflow problems caused by the system’s design
  • Dirty ducts beyond the unit itself

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

What we work on in Coombe

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

In-house cleaning or a specialist?

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.

What happens on the day

There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. If the van will struggle with a lane or gateway near Coombe, let us know and we’ll plan around it.

  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. Filters are dealt with as agreed, and the coils, fan and casing cleaned.
  4. Standing water and slime come out of the tray and the drain is checked.
  5. We close up the unit and send the certificate and before and after pictures.

Getting ready for the visit

  • Clear the space around the work
  • Let us know about permits to work or site inductions
  • Have your last certificate or report to hand

Get a fixed quote

Getting a quote doesn’t take long. 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.
