How we handle AHU cleaning in Wivelsfield Green

We clean air handling units for buildings in Wivelsfield Green and across West Sussex, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We are often asked to deal with blocked condensate drains and slimy trays and dust-coated heating and cooling coils, on filter sections, dampers and louvres and drain trays.

In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.

The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Staff cleaning versus specialist work

In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.

How the visit works

Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. In a small place like Wivelsfield Green, the journey is planned ahead and the visit arranged around the site’s hours.

  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. We clean or change the filters as agreed, then clean the coils, fan and internal panels.
  4. We clean out the drain tray and make sure it drains.
  5. You get a TR19® certificate and a photo report.

How to prepare

  • Mention any parking or loading restrictions
  • Make sure equipment near the work can be switched off and left to cool
  • Have your last certificate or report to hand

Yes. Our area runs across London and the South East, Wivelsfield Green included. Just ring 0345 646 2711 or drop us a line with a few details of the site.

Is Wivelsfield Green within the area you cover?

Do you offer emergency callouts?

Is a quote from pictures possible?

Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. If photos are not enough, we’ll survey first.

What happens to the waste?

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.

Will the ventilation be off while you clean?

Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.

Can you clean without disrupting the building?

Yes, if daytime working is not practical. Tell us when the unit can go off and we’ll work to that.

Will you repair the fan or motor?

Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.

Do you need AHU cleaning in Wivelsfield Green?

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’s the air they breathe for hours on end.

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

  • Plant that has been serviced but not cleaned
  • Dirty fans and fan housings
  • Rooms that smell stuffy when the system runs
  • Drain trays holding standing water

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

Questions to ask before booking

  • What happens if part of the system can’t be accessed
  • If the quote is a fixed price or an estimate
  • Whether they’re fully insured
  • Which accreditations they hold, and whether you can check them

How to choose an extract cleaning contractor

What affects the quote in Wivelsfield Green

You will get a fixed price before any work starts. It takes into account:

  • The size of the system
  • Whether several sites go on one quote
  • The times the site is available
  • One-off work versus a regular cycle

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

There’s no need for technical detail. It helps if you can send:

  • The roof, plant room or outside wall the system runs to
  • Any symptoms, from odd noises to smells or leaks
  • Any access panels or hatches you can see
  • Where the site is and what kind of site it is

To help us quote: where the site is, what it is and its opening hours, a few pictures and any previous report or certificate. Then call 0345 646 2711 or drop us a line.

Managing agents and facilities teams in Wivelsfield Green

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.

Part by part

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.

Heating and cooling coils

Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.

Looking after it afterwards

To keep the system working properly between visits:

  • Look at the condensate drain whenever the unit is serviced
  • Do not ignore odours coming through the grilles
  • Keep the area around the fresh air intake clear
  • Note any water around the unit or leaks below it

When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to confirm water is draining away.

Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
