How we handle AHU cleaning in Swanley

Our AHU cleans for sites in Swanley cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. We are often asked to deal with plant that has been serviced but not cleaned and condensate trays that won’t empty, across dampers and louvres, drain trays and filter sections.

Smaller buildings around Swanley often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Keeping the system healthy

Good habits slow the build-up between visits. A few tips:

  • Report stiff or damaged access doors
  • Report musty smells from the vents straight away
  • Stick to the filter change plan
  • Report water on the plant room floor

Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.

Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.

Questions from Swanley

Do you cover smaller places like Swanley?

Yes, Swanley is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.

Can a school’s ventilation in Swanley be done out of term time?

Yes, and it’s the easiest time to do it. Food Standards Agency records list about 7 schools, colleges and universities with registered kitchens within about a mile and a half of Swanley. Tell us your holiday dates and we’ll book the visit for when the site is empty.

Do you work with multi-site operators?

Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.

Can you set up regular visits?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.

Do you give a certificate after the clean?

Yes, both a certificate and a report with photos. It includes a recommended date for the next check.

Can you fix a faulty AHU?

The clean includes noting faults, but repairs sit with your maintenance contractor, with pictures where it helps.

Do you look at the system first?

Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.

Are you accredited?

Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.

Fixed quotes for AHU cleaning in Swanley

We don’t publish a price list, because no two systems are the same. What we look at:

  • Any permits to work or inductions
  • What state the system is in
  • The scale of the work
  • How easy every part is to reach

You will not 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.

What to send for a quote

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

  • Any access panels or hatches you can see
  • The paperwork from the last visit, if you have it
  • A few general shots of the system
  • When the site is open and when it’s quiet

Multi-site and managed buildings

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

Why act early in Swanley

A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Light use slows the build-up but doesn’t stop it.

No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

Part by part

Internal casing and panels

Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.

Heating and cooling coils

Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.

Ventilation in Swanley buildings

Going by the FSA’s register, there are about 7 schools, colleges and universities and about 11 hospitals, care homes and childcare premises serving food within roughly a mile and a half of the centre of Swanley. Busy, occupied buildings like these are where clean supply air matters most. Swanley, about 14 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible. The nearest hospital to Swanley is Queen Mary's Hospital, about 3.4 miles north-west. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.

Workplaces around Swanley station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. For schools like St Bartholomew's Catholic Primary School, the holidays are the usual time to inspect and clean ventilation.

Signs you need AHU cleaning in Swanley

No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.

These are the problems we see most often:

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

If you run a surgery, dental practice or care home near Swanley, clean ventilation matters as much to you as to a hospital like Queen Mary's Hospital (about 3.4 miles north-west).

How to choose an extract cleaning contractor

The process

Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes one overnight shift for many single units, with bigger plant phased. Your opening hours decide when we come to Swanley, not ours.

  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.

Preparing for the visit

  • Arrange a key holder or contact on site
  • Tell us where we can park and unload
  • Tell us about site rules, permits or sign-in

Getting a quote

Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
