AHU cleaning for sites in Westenhanger

AHU cleaning in Westenhanger

All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you are dealing with units that have only ever had filter changes and units needing a clean before a new tenant or handover, we can help.

For a building in or near Westenhanger, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.

We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Aftercare tips

Think of this as the after-treatment advice, short and simple:

  • Report water on the plant room floor
  • Diary the inspection date recommended in the report
  • Don’t store bins or materials near the intake
  • Change filters on schedule and log each change

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

Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.

What we do, step by step

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 are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a single shift for a typical unit, longer for large or heavily soiled ones. The timing of a visit to Westenhanger is set by you, and the travel is our side of the planning.

  1. We look at the unit and the plant area during the survey.
  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. We close every panel, hand the unit back and send the report and certificate.

Preparing for the visit

  • Find the previous report, if there is one
  • Mention any parking or loading restrictions
  • Let us know about permits to work or site inductions

Ask for a quote

There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, give us a ring on 0345 646 2711 or drop us a line.

Facilities teams in offices, schools and healthcare sites book us too in Westenhanger and across Kent. Larger estates can be phased building by building around the people who use them.

FAQs for Westenhanger

Will you come out to Westenhanger?

Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.

Can the work in Westenhanger be done at night or at weekends?

Yes, evening, overnight and weekend work is normal for us. The work in Westenhanger can fit around your hours. Let us know the hours you are closed and we’ll book within them.

Do you give a certificate after the clean?

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

Can you set up regular visits?

Yes, of course. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.

Can one contract cover all our sites?

Yes. Tell us the addresses and what each needs and we’ll quote them together.

Will you repair the fan or motor?

AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.

Which sectors do you work in?

Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

How far ahead should we book?

That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.

Leave it or put it right?

Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. It’s worth booking a check, because nobody sees inside a duct day to day.

What you pay depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.

What we are called out for in Westenhanger

An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.

Clients typically contact us when they notice something like this:

  • Plant that needs cleaning after a refit
  • Dust built up on fan impellers
  • Condensate trays that won’t empty
  • Stale or musty smells from the ventilation

Classrooms and halls at schools such as Lympne Church of England Primary School are easiest to work in when pupils are away.

What your quote should include

  • Exactly which parts of the system are covered
  • What records you will receive afterwards
  • Whether VAT is included
  • Which accreditations they hold, and whether you can check them
