AHU cleaning across East Wittering

AHU cleaning in East Wittering, done properly

If the units serving a building in East Wittering have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. The work covers drain trays, filter sections and supply and extract fans, and people most often call us about condensate trays that won’t empty and air handling units due a clean after building work.

For a building near East Wittering, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.

It’s worth checking any contractor’s accreditations. 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.

East Wittering: your questions answered

Can you get to a site in East Wittering?

Yes, we work in villages as well as towns, and East Wittering is covered. A survey first, from pictures or a visit, means we arrive with the right kit.

Is AHU cleaning available in East Wittering?

Yes, East Wittering is covered. You can phone us on 0345 646 2711, or send details by email and tell us what needs doing.

How do you keep the site clean during the work?

With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.

Will we get paperwork for the AHU clean?

Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.

What is TR19?

TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

How often do AHUs need cleaning?

Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.

What about areas you cannot get to?

We record them on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.

What do you do with what you remove?

Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.

Between visits

No system stays clean for ever, but care slows the build-up. Our tips:

  • Book the next check in line with the report
  • Keep the certificate and photo report with the plant records
  • Report stiff or damaged access doors
  • Note any water around the unit or leaks below it

Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.

Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

Common problems we fix in East Wittering

Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.

Clients usually contact us after spotting one of these:

  • Dust built up on fan impellers
  • Rooms that smell stuffy when the system runs
  • Dirty filters cutting the airflow
  • Condensate trays that won’t empty

Wherever a school like East Wittering Community Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Choosing a duct cleaning contractor

Staff cleaning versus specialist work

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

What happens on the day

Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes half a day to a full day per unit, with large plant planned over several shifts. A site near East Wittering typically has room to park, so the questions are about access to the system and your 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. The fan and drain tray are cleaned and the drain checked.
  5. We take after photos and issue the certificate and report.

Preparing for the visit

  • Tell us the best time to work, such as after service or at a weekend
  • Find the previous report, if there is one
  • Mention any locked doors, roof access or ceiling voids

Ask for a quote

Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Advice

For landlords and multi-site operators

Facilities teams in offices, schools and healthcare sites book us too across West Sussex. Work can be phased by floor, building or site around the people who use them.

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.

What happens if it’s left?

Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. A site near East Wittering that has to close at short notice is hard to cover for.

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, give us a ring on 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.

What affects the cost of AHU cleaning

Before we fix a price, we need to know a few things. We check:

  • Access, including roofs, risers and ceiling voids
  • How many systems or sites are involved
  • Where the site is and how we reach it
  • The condition of the system

Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.

Helping us quote

The more you tell us, the more accurate the quote. With your enquiry, please include:

  • The site address and the type of premises
  • The times we could work without disrupting the site
  • Any symptoms, from odd noises to smells or leaks
  • A few general shots of the system

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
