AHU cleaning for sites in Warren Street

What AHU cleaning can’t fix

We’d rather tell you now than book work that won’t help, so here are the limits:

  • Damaged coils beyond cleaning
  • Building management system faults
  • Airflow problems caused by the system’s design

If you are not sure, just ring 0345 646 2711 or use the quote form and we’ll give you a straight answer before you book.

Parts of the system we cover

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

AHU cleaning in Warren Street, done properly

No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and send you a fixed quote, so you know where you stand. The work covers heating and cooling coils, filter sections and drain trays, and common reasons people get in touch are odours coming through the supply air and fan sections that haven’t been cleaned in years.

In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.

The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What happens on the day

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 floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. Somewhere like Warren Street, lanes, gates and parking are worth mentioning in advance.

  1. We look at the unit and the plant area during the survey.
  2. We sheet the area and the unit is isolated.
  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

  • Arrange a key holder or contact on site
  • Let us know when the site is closed or quiet
  • Plan for cooking equipment or plant to be off before we arrive

Advice

Looking after it afterwards

Looking after the system between visits is straightforward, and it helps at the next visit:

  • Keep the certificate and photo report with the plant records
  • Report stiff or damaged access doors
  • Keep the area around the fresh air intake clear
  • Keep filter changes on time and recorded

Photos in the report cover the filters, coils, drain tray, fan and casing, 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.

For landlords and multi-site operators

Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.

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.

Part by part

Fans and fan sections

Before the fan is touched, the unit is shut down and made safe in agreement with the site.

Internal casing and panels

We open each section through its doors and close them securely when we’re done, and check every one is shut.

What staff can safely do

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

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. That’s our job.

What we are called out for in Warren Street

Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.

What we are most often called out for:

  • Fan sections that haven’t been cleaned in years
  • Plant that needs cleaning after a refit
  • Coils clogged with dust and debris
  • Debris and leaves in the fresh air intake

Classrooms and halls at schools such as The Lenham School are easiest to work in when pupils are away.
