AHU cleaning across Risinghurst

AHU cleaning for kitchens and businesses in Risinghurst

A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. The work covers internal panels, filter sections and supply and extract fans, and common reasons people get in touch are dust-coated heating and cooling coils and dirty fans and fan housings.

Smaller buildings around Risinghurst often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.

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, and we are fully insured.

How we price AHU cleaning

You will get a fixed price before we start. It’s based on:

  • A single visit or a regular plan
  • The condition we find in the survey
  • The size of the system
  • Parking and loading at the site

The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.

What to send for a quote

There’s no need for technical detail. Just send:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • How we’d reach plant on a roof or in a plant room
  • Your opening hours and when the area is out of use
  • The site address and the type of premises

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

What we do, step by step

Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Tell us about any gates, ladders or locked plant areas at your site near Risinghurst when you book.

  1. The survey covers the unit, its access and how it can be shut down.
  2. We sheet the area and the unit is isolated.
  3. Each section is cleaned of dust, debris and slime.
  4. Coils and trays are cleaned and the condensate drain cleared.
  5. The unit is closed up and handed back, with a report to follow.

How to prepare

  • Mention any locked doors, roof access or ceiling voids
  • Tell us where we can park and unload
  • Tell us about site rules, permits or sign-in

There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To start, call us on 0345 646 2711 or use the quote form.

Advice

Risinghurst questions

Can the work in Risinghurst be done at night or at weekends?

Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Just give us a ring on 0345 646 2711, or email photos with your opening times and we will plan around them.

Can you get to a site in Risinghurst?

Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.

Can you set up regular visits?

Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.

Does the AHU have to be shut down for cleaning?

Yes, while the clean is under way. Out-of-hours work is available so the building isn’t left without ventilation when it’s busy.

Can you clean the ducts connected to the AHU?

Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.

How long does an AHU clean take?

Cleaning takes from a few hours for a compact unit to a day or more for a large one. Bigger units can be phased, so call us on 0345 646 2711 or email us to talk it through.

What happens if you can’t reach some of it?

They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, along with a quote to put access in.

Where does the waste go?

Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.

Landlords, agents and facilities managers

For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

What your team can do, and what needs us

Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Looking after it afterwards

Results last longer with the right care. Here’s what we suggest:

  • Check the drain tray is emptying during routine visits
  • File each AHU report in the maintenance log
  • Don’t store bins or materials near the intake
  • Make sure the unit’s access doors open easily

We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.

Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.

What AHU cleaning can’t fix

To be straight with you, some problems need a different fix:

  • Mechanical faults with motors, belts or bearings
  • Damaged coils beyond cleaning
  • Problems with the unit’s controls or sensors

Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we will tell you honestly before you book.

Where we work

  • Heating and cooling coils
  • Dampers and louvres
  • Internal panels
  • Filter sections
  • Supply and extract fans
  • Drain trays

What we are called out for in Risinghurst

Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.

What we’re most often called out for:

  • Debris and leaves in the fresh air intake
  • Units needing a clean before a new tenant or handover
  • Dust built up on fan impellers
  • Dirty coils holding back the airflow

Wherever a school like Bayards Hill School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Before you book anyone

  • Whether the whole system is included, or only the parts that are easy to reach
  • Proof of accreditation you can verify
  • How areas they cannot reach will be recorded
  • Whether they’re fully insured
