Book AHU cleaning in Oakley Green

Part by part

Heating and cooling coils

Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.

Drain trays

Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.

AHU cleaning in Oakley Green, done properly

The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. Typical jobs include dust-coated heating and cooling coils and plant that has been serviced but not cleaned, across dampers and louvres, internal panels and supply and extract fans.

In a village or hamlet like Oakley Green, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.

Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Oakley Green: your questions answered

Can you clean school ventilation in Oakley Green during the holidays?

Yes. The holidays are the usual time for school work. The FSA’s register shows about 14 schools and colleges with food registrations within roughly a mile and a half of Oakley Green. Just ring 0345 646 2711 or drop us a line with your term dates and we will plan around them.

Do you work at weekends in Oakley Green?

Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.

Do you survey before quoting?

Yes. Photos often do the job, and larger or hidden systems get a visit.

Do you offer maintenance contracts?

Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.

What’s TR19?

A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.

How long does an AHU clean take?

Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, so call 0345 646 2711 or email us to talk it through.

What do you clean inside the unit?

All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.

What do you do with what you remove?

It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.

Staff cleaning versus specialist work

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 doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

Do you need AHU cleaning in Oakley Green?

Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.

Look out for any of the following:

  • Air handling units due a clean after building work
  • Drain trays holding standing water
  • Coils clogged with dust and debris
  • Odours coming through the supply air

Hospitals such as King Edward VII Hospital (about 2.2 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Oakley Green are no different.

What your quote should include

  • What hours they’ll be on site
  • Whether the figure could change on the day
  • Exactly which parts of the system are covered
  • What records you will receive afterwards

How to choose an extract cleaning contractor

Multi-site and managed buildings

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.

If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.

What happens on the day

We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes one overnight shift for many single units, with bigger plant phased. If the van will struggle with a lane or gateway near Oakley Green, let us know and we will plan around it.

  1. We agree a shutdown window that suits the building.
  2. We take before pictures of each section of the unit.
  3. We work through the unit from the intake to the outlet.
  4. We finish with the fan section and the drain tray.
  5. We take after pictures and issue the certificate and report.

Preparing for the visit

  • Have your last certificate or report to hand
  • Make sure someone can let us in and lock up afterwards
  • Tell us about site rules, permits or sign-in

Ask for a quote

There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then send you a fixed quote. To start, phone us on 0345 646 2711 or email us.

Advice

Why act early in Oakley Green

Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. It’s worth booking a check, because nobody sees inside a duct day to day.

What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before we start.

How we price AHU cleaning

There’s no set price list, because no two systems are the same. The quote depends on:

  • Site requirements such as sign-in and permits
  • Whether we need access equipment or extra panels
  • Whether several sites go on one quote
  • A single visit or a regular plan

Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.

What to send for a quote

Photos let us diagnose from a distance. The most useful are:

  • Problems your staff have spotted
  • When the site is open and when it’s quiet
  • The paperwork from the last visit, if you have it
  • Photos showing the whole system and its surroundings

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, you get a fixed price before we start.
