AHU cleaning across Wildhern

Do you need AHU cleaning in Wildhern?

Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Wildhern, that’s air they breathe for hours at a time.

The symptoms we’re asked about most are:

  • Debris and leaves in the fresh air intake
  • Air handling units never cleaned inside
  • Drain trays holding standing water
  • Dust built up on fan impellers

Healthcare ventilation, from large hospitals like Andover War Memorial Hospital (about 2.8 miles south) to small clinics, depends on clean filters, coils and ducts.

Questions to ask before you book

  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • Exactly which parts of the system are covered
  • When the next visit should be, and why
  • Whether they’re fully insured

Choosing a duct cleaning contractor

AHU cleaning in Wildhern, done properly

Where a building in Wildhern has had little more than filter changes, 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 supply and extract fans, drain trays and internal panels, and common reasons people get in touch are rooms that smell stuffy when the system runs and air handling units due a clean after building work.

Somewhere as small as Wildhern, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.

We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

The process

There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Wildhern before we set off.

  1. First we agree when the unit can be switched off, including evenings or weekends.
  2. Before cleaning, each section is photographed.
  3. Filters, coils and internal surfaces are cleaned from intake to discharge.
  4. We finish with the fan section and the drain tray.
  5. We take after pictures and issue the certificate and report.

Before we arrive

  • Mention any parking or loading restrictions
  • Plan for cooking equipment or plant to be off before we arrive
  • Let us know when the site is closed or quiet

What the work involves, part by part

Heating and cooling coils

Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.

Internal casing and panels

We open each section through its doors and close them securely when we’re done, and check every one is shut.

What a clean will not put right

A few issues sit outside what this work can do:

  • Mechanical faults with motors, belts or bearings
  • Coils that are corroded or leaking and need replacing
  • Ductwork downstream of the unit, which is a separate clean

Not sure which it is? You can call 0345 646 2711 or drop us a line and we will tell you honestly.

What the work covers

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

Why deal with it now?

A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. A fault that closes a site in a village like Wildhern affects everyone who depends on it.

We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.

Why us?

  • Fully insured
  • One number for every site across the South East and London
  • A written report with photos after each visit
  • In business since 2009

In-house cleaning or a specialist?

For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.

Ventilation in Wildhern buildings

Andover War Memorial Hospital is the nearest hospital, about 2.8 miles south of Wildhern. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.

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

Fixed quotes for AHU cleaning in Wildhern

There’s no set price list, because sites vary so much. What we look at:

  • How easy every part is to reach
  • How many systems or sites are involved
  • How big the system is
  • A single visit or a regular plan

Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.

What to send for a quote

Photos and a few facts are often enough to price the work. Send what you can of the following:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Your opening hours and when the area is out of use
  • Where the site is and what kind of site it is
  • Photos showing the whole system and its surroundings

Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

What’s TR19?

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

What types of premises do you cover?

Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.

When should our AHU next be cleaned?

It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.

What happens if you cannot reach some of it?

Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.

Can we book visits on a schedule?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
