AHU cleaning for sites in Portsmouth Point

Staff cleaning versus specialist work

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

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.

AHU cleaning in Portsmouth Point

Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers drain trays, supply and extract fans and dampers and louvres, and the jobs we see most are dust built up on fan impellers and dirty coils holding back the airflow.

For a building near Portsmouth Point, 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.

It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Do you need AHU cleaning in Portsmouth Point?

Whatever surrounds a building in Portsmouth Point, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.

The symptoms we’re asked about most include:

  • Dust built up on fan impellers
  • Debris and leaves in the fresh air intake
  • Rooms that smell stuffy when the system runs
  • Plant that needs cleaning after a refit

Wherever a school like St Jude's CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

  • What hours they’ll be on site

What we do, step by step

Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Around Portsmouth Point, access is usually simpler than in a town centre, though gates and roof access are worth mentioning.

  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. Dirt and debris are removed from each section.
  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.

Getting ready for the visit

  • Mention any parking or loading restrictions
  • Mention any sign-in, permit or induction we need
  • Let us know when the site is closed or quiet

FAQs for Portsmouth Point

Can the work in Portsmouth Point be done at night or at weekends?

Yes, nights and weekends are routine for us. Your customers, staff or residents in Portsmouth Point needn’t be disturbed. Your opening times are the first thing we ask for.

Do you do school ventilation cleaning in Portsmouth Point in the summer holidays?

Yes. The holidays are the usual time for school work. Around Portsmouth Point, the Food Standards Agency lists about 30 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you ring 0345 646 2711 or drop us a line, and we will fit the work in.

Is there a survey before the work?

Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.

How long does it take to clean an air handling unit?

It takes from a few hours for a compact unit to a day or more for a large one. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.

Which kinds of sites do you work on?

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

Can we book visits on a schedule?

Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.

What do you do to protect the area?

Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.

Can you look after several sites?

Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.

Looking after it afterwards

So the system stays in good health:

  • Watch for drips or damp patches near the plant
  • Store the TR19 paperwork where auditors can find it
  • Clear leaves and litter away from the intake
  • Keep inspection doors on the unit in good order

Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.

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

What happens if it’s left?

A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. It’s better to plan the work at a site near Portsmouth Point than wait for a failure.

When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account, and the price is fixed before we start.
