AHU cleaning across Hextable

AHU cleaning in Hextable

Our AHU cleaning covers sites in Hextable and the rest of Kent, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers internal panels, drain trays and heating and cooling coils, and common reasons people get in touch are rooms that smell stuffy when the system runs and units needing a clean before a new tenant or handover.

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

We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

For landlords and multi-site operators

Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.

For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.

The process

Each visit runs to the same pattern: protect the area, make the system safe, carry out the AHU cleaning, tidy up and leave you the report. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Tell us about any gates, ladders or locked plant areas at your site near Hextable when you book.

  1. We agree a shutdown window that suits the building.
  2. We take before pictures of each section of the unit.
  3. Filters, coils and internal surfaces are cleaned from intake to discharge.
  4. We finish with the fan section and the drain tray.
  5. After pictures are taken and the certificate issued.

Preparing for the visit

  • Let us know about permits to work or site inductions
  • Agree a time when the area can be out of use
  • Make sure someone can let us in and lock up afterwards

Get a fixed quote

To help us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711, or send details by email.

Looking after it afterwards

Think of this as the after-treatment advice, in brief:

  • Clear leaves and litter away from the intake
  • Keep the certificate and photo report with the plant records
  • Plan the next inspection before the last report gets filed away
  • Keep inspection doors on the unit in good order

When we have 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 make sure it stays clear.

Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.

FAQs for Hextable

Can you clean school ventilation in Hextable during the holidays?

Yes, holiday work suits schools best. Around Hextable, the Food Standards Agency lists about 11 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you phone us on 0345 646 2711 or drop us a line, and we will fit the work in.

Do you work overnight in Hextable?

Yes. We work evenings, overnight and at weekends. It means the site in Hextable keeps running as normal. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.

Can you come out in an emergency?

Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.

What’s TR19?

BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.

How often should an air handling unit be cleaned?

Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.

Do you work in Hextable?

Yes. Our area takes in London and the counties of South East England, Hextable included.

Do you work with multi-site operators?

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

What do you clean inside the unit?

We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.

Why deal with it now?

Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. It’s easy to lose track of when the work was last done on a quieter site.

The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before any work starts.

How we price AHU cleaning

You’ll get a fixed price before work begins. It’s based on:

  • Site requirements such as sign-in and permits
  • Whether we need access equipment or extra panels
  • When the work can happen, such as evenings, overnight or weekends
  • Parking and loading at the site

Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, ring 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.

What we need to know

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

  • The paperwork from the last visit, if you have it
  • The roof, plant room or outside wall the system runs to
  • Any symptoms, from odd noises to smells or leaks
  • The times we could work without disrupting the site

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

What the work involves, part by part

Heating and cooling coils

A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.

Drain trays

Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.

What staff can safely do

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
