AHU cleaning cannot fix everything, and we will tell you before any work starts. It won’t put right:

  • Coils that are corroded or leaking and need replacing

AHU cleaning for kitchens and businesses in Great Horwood

A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. If you have stale or musty smells from the ventilation and dust built up on fan impellers, we can put it right, from heating and cooling coils, dampers and louvres and drain trays onwards.

Somewhere as small as Great Horwood, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.

We are CHAS and SafeContractor accredited, we hold 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.

When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. A fault that closes a site in a village like Great Horwood affects everyone who depends on it.

A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.

Questions from Great Horwood

Can you work in Great Horwood outside opening hours?

Yes. We work evenings, overnight and at weekends. That way a site in Great Horwood does not have to lose a day’s trading. Just call us on 0345 646 2711, or send details by email with your opening times and we will plan around them.

Is Great Horwood within the area you cover?

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

What do you do with what you remove?

It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.

Do you need to switch the unit off?

Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.

Do you do ventilation duct cleaning too?

Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.

Do you give a certificate after the clean?

Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.

Are you insured?

Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.

What’s included in an AHU clean?

Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.

Fixed quotes for AHU cleaning in Great Horwood

Some jobs are bigger than they look, and some smaller. The main factors:

  • When the work can happen, such as evenings, overnight or weekends
  • Whether we need access equipment or extra panels
  • Where the site is and how we reach it
  • The condition of the system

Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.

Asking for a quote

You don’t need the technical terms. Just send:

  • A few general shots of the system
  • When the site is open and when it’s quiet
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • The site address and the type of premises

If you need AHU cleaning in Great Horwood, phone us on 0345 646 2711 or email us. Let us know the site type and the opening hours, and send photos or your last report if you can. We usually send a fixed quote within one working day.

What staff can safely do

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

What we are called out for in Great Horwood

Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.

It’s time to book a visit if you see:

  • Fan sections that haven’t been cleaned in years
  • Units needing a clean before a new tenant or handover
  • Units that have only ever had filter changes
  • Dirty coils holding back the airflow

Healthcare buildings such as Buckingham Community Hospital, about 5 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Great Horwood, yours matters too.

Questions to ask before you book

  • What’s included in the scope, part by part
  • What hours they’ll be on site
  • Which accreditations they hold, and whether you can check them
  • How areas they cannot reach will be recorded

Questions to ask before booking

Aftercare tips

Once we’ve finished, these simple steps help:

  • Make sure the unit’s access doors open easily
  • Report water on the plant room floor
  • Stick to the filter change plan
  • Check the drain tray is emptying during routine visits

The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.

Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

How it works

A visit follows the same order every time: protect the area, make the system safe, carry out the AHU cleaning, clear away and hand over the paperwork. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Rural roads and tight entrances are worth telling us about before a visit to Great Horwood.

  1. We look at the unit and the plant area during the survey.
  2. The area is protected and the unit made safe.
  3. Each section is cleaned of dust, debris and slime.
  4. We clean the coils and clear the tray and drain.
  5. We close every panel, hand the unit back and send the report and certificate.

Before we arrive

  • Allow time for equipment near the work to be turned off and cool down
  • Tell us the best time to work, such as after service or at a weekend
  • Tell us where we can park and unload
