AHU cleaning across Bridgemary

AHU cleaning for kitchens and businesses in Bridgemary

Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you are dealing with dust-coated heating and cooling coils and filters that are clogged or overdue, we can help.

Smaller buildings around Bridgemary often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.

Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

When to call us in Bridgemary

Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.

Common reasons sites call us include:

  • Dust-coated heating and cooling coils
  • Debris and leaves in the fresh air intake
  • Units that have only ever had filter changes
  • Dirty filters cutting the airflow

Hospitals such as Gosport War Memorial Hospital (about 2.1 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Bridgemary are no different.

Questions to ask before booking

Keeping the system healthy

Once we’ve finished, these simple steps help:

  • Report musty smells from the vents straight away
  • Diary the inspection date recommended in the report
  • Watch for drips or damp patches near the plant
  • File each AHU report in the maintenance log

Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.

Keep the area around the intake clear. Anything around the intake is likely to be drawn in.

FAQs for Bridgemary

Do you work overnight in Bridgemary?

Yes, nights and weekends are routine for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.

Do you cover smaller places like Bridgemary?

Yes. Bridgemary is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

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 we’ll suggest an interval after the first clean.

Can you fix a faulty AHU?

We clean the unit and flag faults rather than repair them, with the details in the report.

Can you price the work without visiting?

Normally, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. If pictures aren’t enough, we’ll survey first.

Will the ventilation be off while you clean?

Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.

Do you have a 24/7 line?

Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.

What about areas you cannot get to?

Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.

Ventilation in Bridgemary buildings

There are about 20 schools, colleges and universities, about 27 care, childcare and hospital premises and about 3 hotels, B&Bs and guest houses on the FSA’s food hygiene register in Bridgemary and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Gosport War Memorial Hospital is the nearest hospital, about 2.1 miles south-east of Bridgemary. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.

For schools like Rowner Junior, the holidays are the usual time to inspect and clean ventilation.

What we do, step by step

A visit follows the same order every time: protect the area, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. We plan the journey to Bridgemary and bring what the job is likely to need.

  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. After photos are taken and the certificate issued.

Managing agents and facilities teams in Bridgemary

We work for landlords, managing agents and facilities managers as well as the people running the site. 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.

Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.

In-house cleaning or a specialist?

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

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

Why it’s worth doing now in Bridgemary

Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. It’s easy to lose track of when the work was last done on a quieter site.

Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, give us a ring on 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.

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.

Fans and fan sections

Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
