About our AHU cleaning in Great Holcombe
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. We’re often asked to deal with dirty coils holding back the airflow and dirty filters cutting the airflow, across filter sections, supply and extract fans and drain trays.
In a village or hamlet like Great Holcombe, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Between visits
Think of this as the after-treatment advice, in brief:
- Report stiff or damaged access doors
- Keep the area around the fresh air intake clear
- Keep the certificate and photo report with the plant records
- Check the drain tray is emptying during routine visits
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.

Managing agents and facilities teams in Great Holcombe
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Great Holcombe: your questions answered
Can the work in Great Holcombe be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Great Holcombe needn’t be disturbed. Your opening times are the first thing we ask for.
Do you work in villages like Great Holcombe?
Yes, Great Holcombe is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Is a quote from pictures possible?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
What happens if you can’t reach some of it?
Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
Where does the waste go?
It leaves the site with us at the end of the visit. During the work, it’s contained to keep the area clean.
Do you do ventilation duct cleaning too?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.

What else we do in Great Holcombe
The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes anything from half a day for one small unit to several shifts for a plant room full of them. A quick note on how to find the site and where to park makes a visit to Great Holcombe run smoothly.
- We survey the unit from pictures or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Let us know about parking and loading
- Clear loose items from the work area

Advice
Common problems we fix in Great Holcombe
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
These are the problems we see most often:
- Air handling units never cleaned inside
- Fan sections that haven’t been cleaned in years
- Intake sections clogged with outdoor debris
- Rooms that smell stuffy when the system runs
For buildings in and around Great Holcombe, TR19® Air cleaning starts with an inspection.

How we price AHU cleaning
Your quote is based on your site. We consider:
- Parking and loading at the site
- What state the system is in
- Access, including roofs, risers and ceiling voids
- When the work can happen, such as evenings, overnight or weekends
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before any work starts.
What we need to know
We can often survey from pictures. Try to include:
- How we’d reach plant on a roof or in a plant room
- Problems your staff have spotted
- The postcode and the type of business
- Detail shots of panels, filters and grilles
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, ring 0345 646 2711, or send details by email.
What AHU cleaning can’t fix
In fairness, there are a few things this work will not fix:
- Damaged coils beyond cleaning
- Dirty ducts beyond the unit itself
- Ventilation that was badly designed in the first place
If in doubt, call 0345 646 2711, or send details by email and we will say what we think before you book.
