AHU cleaning for sites in Alverstone

AHU cleaning in Alverstone

An AHU clean is a thorough examination and treatment of the unit. 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 dirty coils holding back the airflow and leaves and litter drawn into the unit, across heating and cooling coils, dampers and louvres and filter sections.

Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.

Each visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards

Here’s the after-treatment advice, short and simple:

  • Watch for drips or damp patches near the plant
  • Keep the certificate and photo report with the plant records
  • Stick to the filter change plan
  • Report musty smells from the vents right away

Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to make sure it stays clear.

Change or clean filters on time. Once filters clog, dirt starts getting past them.

AHU cleaning around Alverstone

There are about 7 hospitals, care homes and childcare premises and about 17 hotels and guest houses on the FSA’s food hygiene register in Alverstone and the streets around it, up to about 1.5 miles out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 2 miles south of Alverstone is Arthur Webster Memorial Hospital for Children, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

Healthcare buildings such as Arthur Webster Memorial Hospital for Children, about 2 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Alverstone, yours matters too.

The process

The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes a single shift for a typical unit, longer for large or heavily soiled ones, and the area is cleaned down before we leave. We agree a date with you, plan the drive to Alverstone and turn up when the site is quiet.

  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. The fan and drain tray are cleaned and the drain checked.
  5. We take after pictures and issue the certificate and report.

How to prepare

  • Let us know about parking and loading
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Dig out any earlier paperwork for the system

Advice

Multi-site and managed buildings

We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.

From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.

Common questions in Alverstone

Do you cover smaller places like Alverstone?

Yes, Alverstone is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.

Is AHU cleaning available in Alverstone?

Yes. We work across London and the South East, and Alverstone is part of that. Just give us a ring on 0345 646 2711 or email us with a few details of the site.

What happens to the waste?

It leaves the site with us at the end of the visit. During the work, it’s contained to keep the area clean.

How long will the unit be out of action?

As a guide, it takes half a day to a full day per unit, with large plant planned over several shifts. We plan the shutdown around that, out of hours if needed.

Is a quote from pictures possible?

Typically, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and a fixed quote typically follows within one working day. If pictures are not enough, we’ll survey first.

Do you work with multi-site operators?

Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Every site has its own report.

Do you have a 24/7 line?

Yes. There’s a 24/7 emergency line, for problems that can’t wait. Ring any time and tell us what’s happened.

Can you clean without disrupting the building?

Yes. We work evenings, overnight and weekends, so the building keeps running in the day.

When something else is needed

Not every problem is solved by AHU cleaning, and we’d rather say so up front. It does not solve:

  • Problems with the unit’s controls or sensors
  • Mechanical faults with motors, belts or bearings
  • Ventilation that was badly designed in the first place

If you are not sure, just call 0345 646 2711, or send details by email and we will give you a straight answer.

What we work on in Alverstone

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

What we’re called out for in Alverstone

Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.

Signs it’s time to call us include:

  • Dirty fans and fan housings
  • Units that have only ever had filter changes
  • Plant that needs cleaning after a refit
  • Drain trays holding standing water

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

Comparing quotes

  • Whether VAT is included
  • If they look at the system before pricing
  • Whether a written report and photos are included
  • When the next visit should be, and why

Questions to ask before you book

What the work involves, part by part

Internal casing and panels

Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.

Heating and cooling coils

Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.

Why it’s worth doing now in Alverstone

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. Systems in rural buildings are often out of sight and out of mind.

You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.
