AHU cleaning for sites in Freemantle

When to call us in Freemantle

Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.

If you notice any of these, it’s worth a diagnosis:

  • Air handling units due a clean after building work
  • Units that have only ever had filter changes
  • Rooms that smell stuffy when the system runs
  • Dirty filters cutting the airflow

If you manage offices or shops near Millbrook (Hants) station, their ventilation can be inspected and cleaned out of hours.

What to look for in a quote

  • Whether the quote shows VAT
  • How areas they cannot reach will be recorded
  • Which accreditations they hold, and whether you can check them
  • Whether a written report and photos are included

How to choose an extract cleaning contractor

How we handle AHU cleaning in Freemantle

Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. If you have dirty coils holding back the airflow and stale or musty smells from the ventilation, we can help, from heating and cooling coils, internal panels and supply and extract fans onwards.

Smaller buildings around Freemantle often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.

Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What happens if it’s left?

When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. Around Freemantle, a kitchen or building out of action is missed right away.

Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.

What you get with us

  • Member of BESCA Vent Hygiene Elite, cleaning to BESA TR19® Grease
  • Every visit written up, with pictures
  • A fixed price before any work starts

Take a look at how cleaning jobs are priced and how to check a contractor.

Keeping the system healthy

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

  • Make sure condensate is draining away
  • Make sure the unit’s access doors open easily
  • Diary the inspection date recommended in the report
  • Stick to the filter change plan

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.

Managing agents and facilities teams in Freemantle

Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.

We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.

What affects the cost of AHU cleaning

We do not publish a price list, because sites vary so much. The quote depends on:

  • Whether we need access equipment or extra panels
  • How big the system is
  • The condition we find in the survey
  • Site requirements such as sign-in and permits

No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

What we need to know

When you contact us, these details help:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • The times we could work without disrupting the site
  • How we’d reach plant on a roof or in a plant room
  • A few general shots of the system

Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.

How it works

At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Visits to a place like Freemantle are planned ahead, so we arrive with what the survey says the job needs.

  1. The survey covers the unit, its access and how it can be shut down.
  2. We sheet the area and the unit is isolated.
  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

  • Clear loose items from the work area
  • Tell us where we can park and unload
  • Mention any locked doors, roof access or ceiling voids

Ask for a quote

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

In-house cleaning or a specialist?

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
