AHU cleaning in Ditchling Common

How it works

On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere like Ditchling Common, lanes, gates and parking are worth mentioning in advance.

  1. The survey covers the unit, its access and how it can be shut down.
  2. The area is protected and the unit made safe.
  3. Dirt and debris are removed from each section.
  4. Coils and trays are cleaned and the condensate drain cleared.
  5. We close every panel, hand the unit back and send the report and certificate.

Getting ready for the visit

  • Plan for cooking equipment or plant to be off before we arrive
  • Let us know about permits to work or site inductions
  • Have your last certificate or report to hand

Advice

How we handle AHU cleaning in Ditchling Common

The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. If you are dealing with air handling units due a clean after building work and dirty coils holding back the airflow, we can put it right, from dampers and louvres, supply and extract fans and filter sections onwards.

Somewhere as small as Ditchling Common, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.

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

Common questions in Ditchling Common

Can you work in Ditchling Common outside opening hours?

Yes, out-of-hours work is a big part of what we do. That way a site in Ditchling Common doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.

Do you cover smaller places like Ditchling Common?

Yes, Ditchling Common is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.

Do you survey before quoting?

Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.

What if parts of the system cannot be reached?

We record them on the report, with photos where possible, and we explain what access is needed, for example new access panels.

What should I send you?

Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.

Will the ventilation be off while you clean?

Yes, while the clean is under way. Out-of-hours work is available so the building is not left without ventilation when it’s busy.

What’s TR19?

A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.

How often do AHUs need cleaning?

TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.

How the job changes from site to site

Rooftop and plant room units

Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.

Internal casing and panels

Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.

Landlords, agents and facilities managers

Facilities teams in offices, schools and healthcare sites book us too in Ditchling Common and across West Sussex. Larger estates can be phased building by building around the people who use them.

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.

Between visits

After the visit, a few habits help the work last:

  • Keep the area around the fresh air intake clear
  • Report water on the plant room floor
  • Keep filter changes on time and recorded
  • Make sure the unit’s access doors open easily

The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.

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

In-house cleaning or a specialist?

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

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.

Leave it or put it right?

Stuffy rooms and stale smells in a building in Ditchling Common can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. In a place like Ditchling Common, ductwork and fans are easy to forget until something goes wrong.

We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.
