AHU cleaning for sites in Hollybushes

AHU cleaning in Hollybushes, done properly

Where a building in Hollybushes has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. Common call-outs are for plant that needs cleaning after a refit and fan sections that haven’t been cleaned in years, on filter sections, internal panels and drain trays.

Somewhere as small as Hollybushes, ducted ventilation is normally 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.

It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What affects the cost of AHU cleaning

Before we fix a price, we need to know a few things. We look at:

  • When the work can happen, such as evenings, overnight or weekends
  • How many systems or sites are involved
  • Whether we need access equipment or extra panels
  • Whether it’s a one-off visit or part of a schedule

One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before work begins.

What to send for a quote

To help us quote quickly, send us:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • The postcode and the type of business
  • The paperwork from the last visit, if you have it
  • When the site is open and when it’s quiet

The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Ventilation in Hollybushes buildings

What happens if it’s left?

Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. Out of sight is the usual reason a rural system goes too long without attention.

When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.

How the job changes from site to site

Rooftop and plant room units

Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.

Internal casing and panels

We open each section through its doors and close them securely when we’re done before the unit is handed back.

How it works

When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes from a few hours for a compact unit to a day or more for a large one. Visits to a village like Hollybushes are booked in advance, at a time that suits whoever runs the site.

  1. First we agree when the unit can be switched off, including evenings or weekends.
  2. Before cleaning, each section is photographed.
  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.

Getting ready for the visit

  • Mention any sign-in, permit or induction we need
  • Have your last certificate or report to hand
  • Make sure equipment near the work can be switched off and left to cool

Getting a quote

Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.

Managing agents and facilities teams in Hollybushes

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. Where responsibility is shared, records matter even more.

From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.

What a clean won’t put right

Before you book, it helps to know what’s not included:

  • Ductwork downstream of the unit, which is a separate clean
  • A system that is undersized for the building
  • Coils that are corroded or leaking and need replacing

Not sure which it is? You can ring 0345 646 2711 or drop us a line and we’ll tell you honestly before booking.

Where we work

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

Looking after it afterwards

How long the results last depends on use and care. We suggest:

  • Watch for drips or damp patches near the plant
  • Clear leaves and litter away from the intake
  • Keep inspection doors on the unit in good order
  • Stick to the filter change plan

The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.

Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.

Hollybushes questions

Do you work in villages like Hollybushes?

Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.

Can you work in Hollybushes outside opening hours?

Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Hollybushes needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.

Can you fix a faulty AHU?

Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.

Can one contract cover all our sites?

Yes. Send the list of sites and the work at each and we will quote them together.

Is there a report after cleaning?

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

Do you offer emergency callouts?

Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.

What do you need from me for a quote?

Where the site is, what it is and when it’s open, along with a few photos and any previous report.

What’s TR19?

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