AHU cleaning across Sheerness

AHU cleaning in Sheerness, done properly

All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you are dealing with dirty fans and fan housings and drain trays holding standing water, we can put it right.

Smaller buildings around Sheerness often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.

Every visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Your questions about AHU cleaning in Sheerness

Can you clean school ventilation in Sheerness during the holidays?

Yes, and it’s the easiest time to do it. With about 13 schools and colleges on the FSA’s register within roughly a mile and a half of Sheerness, it pays to plan holiday dates ahead. Just ring 0345 646 2711 or send us an email with your term dates and we will plan around them.

Can you get to a site in Sheerness?

Yes. Sheerness is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.

What should I send you?

Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply call 0345 646 2711 or email us.

Do you give a certificate after the clean?

Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.

Is a quote from pictures possible?

Typically, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and we usually come back within one working day. If photos are not enough, we will survey first.

What does TR19 mean?

TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

What’s included in an AHU clean?

Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.

How much does AHU cleaning cost in Sheerness?

Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will typically reply within one working day.

Between visits

A little care between visits keeps the system in better shape. Our advice:

  • File each AHU report in the maintenance log
  • Note any water around the unit or leaks below it
  • Report musty smells from the vents straight away
  • Look at the condensate drain whenever the unit is serviced

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.

Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.

What we do, step by step

Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Evenings, weekends or a closed day all work for a site in a place like Sheerness.

  1. First the unit is surveyed, from pictures or a visit, and the scope agreed.
  2. The unit is shut down with your site team and the area protected.
  3. We clean or change the filters as agreed, then clean the coils, fan and internal panels.
  4. Drain trays are cleared and cleaned and the outlet checked.
  5. A TR19® certificate and photo report follow the clean.

Before we arrive

  • Let us know about parking and loading
  • Arrange a key holder or contact on site
  • Move anything stored near the system

Getting a quote

Photos are enough for some jobs, while others need a look on site. 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 any work starts.

When to call us in Sheerness

Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.

What we’re most often called out for:

  • Units needing a clean before a new tenant or handover
  • Plant that has been serviced but not cleaned
  • Filters that are clogged or overdue
  • Drain trays holding standing water

For schools like Rose Street Primary School, the holidays are the usual time to inspect and clean ventilation.

Before booking anyone

  • Whether the work can be done while the site is closed
  • Proof of insurance
  • If the quote is a fixed price or an estimate
  • How they set the interval to the next visit

Questions to ask before you book

What AHU cleaning can’t fix

To be straight with you, some problems need a different fix:

  • Faulty motors, drives or bearings
  • Airflow problems caused by the system’s design
  • Coils that are corroded or leaking and need replacing

If you are not sure, just call 0345 646 2711 or send us an email and we’ll give you a straight answer.

Where we work

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

What staff can safely do

A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

If your staff spot something 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 affects the cost of AHU cleaning

We quote each job individually. These are the things that affect it:

  • Whether several sites go on one quote
  • The scale of the work
  • Parking and loading at the site
  • How easy every part is to reach

One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.

Asking for a quote

To speed up the quote, send us:

  • When the site is open and when it’s quiet
  • The site address and the type of premises
  • Any symptoms, from odd noises to smells or leaks
  • Any access panels or hatches you can see

To help us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Then phone us on 0345 646 2711 or use the quote form.
