AHU cleaning in West Wittering

Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. We are often asked to deal with debris and leaves in the fresh air intake and filters that are clogged or overdue, on supply and extract fans, heating and cooling coils and drain trays.

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

Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Why it’s worth doing now in West Wittering

A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. If the system at a site near West Wittering fails, there may be nowhere nearby to move to.

Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

Why West Wittering businesses choose us

  • Full insurance on every job
  • Fixed quotes from a survey or photos
  • A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
  • Accredited under CHAS and SafeContractor, with ISO 9001

When to call us in West Wittering

Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.

Any of these means the system needs a check-up:

  • Stale or musty smells from the ventilation
  • Intake sections clogged with outdoor debris
  • Dust built up on fan impellers
  • Air handling units due a clean after building work

Wherever a school like West Wittering Parochial Church of England School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What your quote should include

  • Which accreditations they hold, and whether you can check them
  • Whether the work can be done while the site is closed
  • What paperwork you get at the end
  • Exactly which parts of the system are covered

Choosing a duct cleaning contractor

What staff can safely do

Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.

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. Leave those to us.

FAQs for West Wittering

Can you get to a site in West Wittering?

Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.

Do you work overnight in West Wittering?

Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in West Wittering needn’t be disturbed. Let us know the hours you are closed and we will book within them.

Are you insured?

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

How much notice should we give?

Earlier is better, especially for out-of-hours work. We normally quote within one working day, and there’s a 24/7 line for emergencies.

What is TR19?

BESA’s ventilation hygiene 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.

When should our AHU next be cleaned?

That’s 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 work with multi-site operators?

Yes. Send the list of sites and the work at each and we will quote them together.

How much does AHU cleaning cost in West Wittering?

It depends on the site, so we quote each one individually. For a quote, phone us on 0345 646 2711 or use the quote form with the site type, opening hours and a few pictures.

How the visit works

We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere like West Wittering, lanes, gates and parking are worth mentioning in advance.

  1. We start with a survey of the unit and a fixed quote for the work.
  2. The unit is shut down with your site team and the area protected.
  3. Filters are dealt with as agreed, and the coils, fan and casing cleaned.
  4. Drain trays are cleared and cleaned and the outlet checked.
  5. You get a TR19® certificate and a photo report.

How to prepare

  • Plan for cooking equipment or plant to be off before we arrive
  • Find the previous report, if there is one
  • Tell us about site rules, permits or sign-in

Ask for a quote

Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.

Between visits

Results last longer with the right care. We suggest:

  • Watch for drips or damp patches near the plant
  • Stick to the filter change plan
  • Report musty smells from the vents right away
  • Make sure the unit’s access doors open easily

You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.

Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.

Fixed quotes for AHU cleaning in West Wittering

A fixed price needs a few facts first. We look at:

  • The scale of the work
  • Whether we need access equipment or extra panels
  • Working hours and out-of-hours timing
  • Whether it’s a one-off visit or part of a schedule

Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.

What to send for a quote

A few details help us quote accurately. With your enquiry, please include:

  • The postcode and the type of business
  • The times we could work without disrupting the site
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Close-ups of filters, grilles, hatches or access panels

We don’t publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.
