AHU cleaning for sites in Stone Corner

What happens on the day

Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes from a few hours for a compact unit to a day or more for a large one. In a small place like Stone Corner, the journey is planned ahead and the visit arranged around the site’s hours.

  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 photos and issue the certificate and report.

Preparing for the visit

  • Have your last certificate or report to hand
  • Let us know about parking and loading
  • Mention any locked doors, roof access or ceiling voids

About our AHU cleaning in Stone Corner

We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. We are often asked to deal with dirty coils holding back the airflow and air handling units with blocked filters, on heating and cooling coils, supply and extract fans and internal panels.

In a village or hamlet like Stone Corner, few buildings have mechanical ventilation, 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.

What a clean won’t put right

AHU cleaning cannot fix everything, and we’d rather say so up front. It does not solve:

  • Problems with the unit’s controls or sensors
  • Breakdowns that need a mechanical engineer
  • Coils that are corroded or leaking and need replacing

If in doubt, phone us on 0345 646 2711 or email us and we’ll say what we think.

Where we work

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

How we price AHU cleaning

The price is fixed before any work begins. It takes into account:

  • Where the site is and how we reach it
  • The times the site is available
  • The number of sites or systems
  • A single visit or a regular plan

What you pay reflects the actual work. That is why we survey first, from pictures or on site, and why the quote is fixed before work begins.

Asking for a quote

Before you ask for a quote, gather:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • How we’d reach plant on a roof or in a plant room
  • The site address and the type of premises
  • Any previous report or certificate

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 work begins.

Managing agents and facilities teams in Stone Corner

From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.

Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.

What we are called out for in Stone Corner

Air handling units are typically tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.

Clients typically contact us after spotting something like this:

  • Intake sections clogged with outdoor debris
  • Drain trays holding standing water
  • Plant that needs cleaning after a refit
  • Units that have only ever had filter changes

Around Stone Corner, an air handling unit’s drain tray is checked for standing water as a matter of course.

Questions to ask before you book

  • Whether they recommend a next date
  • Proof of accreditation you can verify
  • What records you’ll receive afterwards
  • When they can work, and whether that is outside your opening hours

Stone Corner: your questions answered

Is Stone Corner within the area you cover?

Yes. Villages and rural sites across the South East are part of our work, Stone Corner included. Just mention lanes, gates or anything else about the site when you book.

Do you cover Stone Corner for AHU cleaning?

Yes. We work across London and the South East, and Stone Corner is part of that. Just call us on 0345 646 2711, or send details by email with a few details of the site.

What information do you need?

Some photos and a quick description of the system, with the address and opening hours. If we need more, we will ask.

Is there a survey before the work?

Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.

Can you price the work without visiting?

Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.

Do you repair air handling units?

We clean the unit and flag faults rather than repair them, with the details in the report.

What do you clean inside the unit?

Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.

How much notice should we give?

Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.

What staff can safely do

Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.

Between visits

Simple habits between visits make a real difference. We recommend:

  • Look at the condensate drain whenever the unit is serviced
  • Note any water around the unit or leaks below it
  • Keep the certificate and photo report with the plant records
  • Diary the inspection date recommended in the report

You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.

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.
