What AHU cleaning cannot fix

Not every problem is solved by AHU cleaning, and we’d rather say so up front. It won’t put right:

  • Ventilation that was badly designed in the first place
  • Mechanical faults with motors, belts or bearings
  • Controls and BMS settings that run the unit

If you are not sure, just give us a ring on 0345 646 2711 or use the quote form and we will give you a straight answer before you book.

Where we work

  • Internal panels
  • Filter sections
  • Dampers and louvres
  • Heating and cooling coils
  • Drain trays
  • Supply and extract fans

How we handle AHU cleaning in Little Posbrook

Our AHU cleans for sites in Little Posbrook cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. Typical jobs include intake sections clogged with outdoor debris and air handling units with blocked filters, on filter sections, dampers and louvres and drain trays.

Somewhere as small as Little Posbrook, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.

Duct Doctor has been trading since 2009, as 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.

What we do, step by step

We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. Photos of the system and how to reach it help us plan a visit to Little Posbrook.

  1. The survey covers the unit, its access and how it can be shut down.
  2. The area is protected and the unit made safe.
  3. Dirt and debris are removed from each section.
  4. We clean the coils and clear the tray and drain.
  5. The unit is closed up and handed back, with a report to follow.

Getting ready for the visit

  • Agree a time when the area can be out of use
  • Let us know about parking and loading
  • Arrange a key holder or contact on site

How to get a quote

Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.

Part by part

Heating and cooling coils

Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.

Filters

Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.

FAQs for Little Posbrook

Can you work in Little Posbrook outside opening hours?

Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Little Posbrook needn’t be disturbed. Tell us your opening hours when you ask for a quote.

Do you work in villages like Little Posbrook?

Yes, we work in villages as well as towns, and Little Posbrook is covered. A survey first, from photos or a visit, means we arrive with the right kit.

Are you fully insured?

Yes. We’re fully insured, and the details are available on request.

What does AHU cleaning cost?

We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before any work starts.

What do you do with what you remove?

We take it away when we go. While we work, it’s kept contained so the area stays clean.

How long will the unit be out of action?

As a guide, it takes one overnight shift for many single units, with bigger plant phased. We plan the shutdown around that, out of hours if needed.

How much notice do you need?

It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.

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. The Vent Hygiene Elite scheme is run by BESCA and audited independently.

Fixed quotes for AHU cleaning in Little Posbrook

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

  • What state the system is in
  • How easy every part is to reach
  • One-off work versus a regular cycle
  • Site rules, permits and inductions

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.

Helping us quote

To speed up the quote, send us:

  • Wide pictures of the system and the area around it
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • The site address and the type of premises
  • Where the plant sits or the system leaves the building, such as a roof or outside wall

Need a price for AHU cleaning? Please call us on 0345 646 2711 or email us with a few details about the site. We’ll talk you through the work and give you a fixed quote before you commit to anything.

Leave it or put it right?

Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. A planned visit to Little Posbrook is easier to arrange than an emergency callout.

Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.

Do you need AHU cleaning in Little Posbrook?

No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.

These are the problems we see most often:

  • Rooms that smell stuffy when the system runs
  • Plant that has been serviced but not cleaned
  • Intake sections clogged with outdoor debris
  • Dirty fans and fan housings

School buildings such as Stubbington House School are normally done in the holidays, so classrooms aren’t disturbed.

What your quote should include

  • Whether they’re fully insured
  • What happens if part of the system can’t be accessed
  • Whether the price is fixed
  • How VAT is shown on the quote

Choosing a duct cleaning contractor

Staff cleaning versus specialist work

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
