What staff can safely do

A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.

How we handle AHU cleaning in Lavendon

Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers heating and cooling coils, drain trays and dampers and louvres, and people most often call us about fan sections that haven’t been cleaned in years and units that have only ever had filter changes.

Work in a small place like Lavendon starts with agreeing access and timings.

Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

When to call us in Lavendon

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 are:

  • Intake sections clogged with outdoor debris
  • Stale or musty smells from the ventilation
  • Units needing a clean before a new tenant or handover
  • Blocked condensate drains and slimy trays

School buildings such as Lavendon School are normally done in the holidays, so classrooms aren’t disturbed.

Questions to ask before booking

  • Whether a written report and photos are included
  • Proof of accreditation you can verify
  • How areas they cannot reach will be recorded
  • What insurance they carry

How the job changes from site to site

Drain trays

Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.

Fans and fan sections

Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.

Common questions in Lavendon

Is Lavendon in your area for AHU cleaning?

Yes. Our area runs across London and the South East, Lavendon included. To start, phone us on 0345 646 2711, or email photos with a few photos of the system.

Can you come to Lavendon after we close?

Yes. We work evenings, overnight and at weekends. It means the site in Lavendon keeps running as normal. Let us know the hours you’re closed and we’ll book within them.

Will we get paperwork for the AHU clean?

Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.

Do you have insurance?

Yes. Full insurance covers our work and have been trading since 2009.

Will the ventilation be off while you clean?

Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.

What is TR19?

A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.

How often do AHUs need cleaning?

That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.

Do you have a 24/7 line?

Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.

What happens on the day

Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes from a few hours for a compact unit to a day or more for a large one. In a small place like Lavendon, the journey is planned ahead and the visit arranged around the site’s hours.

  1. First we agree when the unit can be switched off, including evenings or weekends.
  2. Before cleaning, each section is photographed.
  3. We work through the unit from the intake to the outlet.
  4. We finish with the fan section and the drain tray.
  5. After photos are taken and the certificate issued.

Preparing for the visit

  • Make sure someone can let us in and lock up afterwards
  • Tell us the best time to work, such as after service or at a weekend
  • Make sure equipment near the work can be switched off and left to cool

Advice

Why deal with it now?

Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. In a small place like Lavendon, a system that fails can take a site out of use.

No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

Honest limits

An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:

  • Leaking heating or cooling coils
  • Ventilation that was badly designed in the first place
  • Controls and BMS settings that run the unit

If in doubt, ring 0345 646 2711 or send us an email and we’ll say what we think.

What we work on in Lavendon

  • Internal panels

  • Heating and cooling coils

Lavendon buildings and their air

Food Standards Agency records list about 3 care, childcare and hospital premises registered as food businesses within roughly a mile and a half of the centre of Lavendon. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Lavendon, about 52 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.

Around Lavendon, as anywhere, ventilation cleaning begins with an inspection.

Looking after it afterwards

Looking after the system between visits is straightforward, and it makes the next visit easier:

  • Diary the inspection date recommended in the report
  • Flag stale or damp smells in the supply air
  • Keep the certificate and photo report with the plant records
  • Make sure the unit’s access doors open easily

When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.

Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
