In-house cleaning or a specialist?
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.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
AHU cleaning in Crockerhill, done properly
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. The work covers supply and extract fans, heating and cooling coils and dampers and louvres, and the jobs we see most are intake sections clogged with outdoor debris and plant that has been serviced but not cleaned.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Every visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Leave it or put it right?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. It’s worth booking a check, because nobody sees inside a duct day to day.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
Why us?
- Fully insured
- A written report with pictures after every visit

Part by part
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Don’t store bins or materials near the intake
- Report stiff or damaged access doors
- Note any water around the unit or leaks below it
- Book the next check in line with the report
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.

What else we do in Crockerhill
What happens on the day
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. If the van will struggle with a lane or gateway near Crockerhill, let us know and we will plan around it.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Tell us where we can park and unload

Fixed quotes for AHU cleaning in Crockerhill
The price is fixed before any work begins. It’s based on:
- How big the system is
- A single visit or a regular plan
- Whether we need access equipment or extra panels
- What state the system is in
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- Wide photos of the system and the area around it
- Any access panels or hatches you can see
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business

Crockerhill: your questions answered
Will you come out to Crockerhill?
Yes, we work in villages as well as towns, and Crockerhill is covered. Let us know about access, parking and anything unusual about getting there when you book.
Can you clean school ventilation in Crockerhill during the holidays?
Yes, out-of-term visits are normal for schools. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Crockerhill. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
Do you clean the ductwork as well?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, with new panels fitted where necessary.
How much does AHU cleaning cost in Crockerhill?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before any work starts.
Can you quote from photos?
Often, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Crockerhill buildings and their air
The FSA’s food hygiene register lists about 9 care, childcare and hospital premises with registered kitchens or food service within roughly a mile and a half of the centre of Crockerhill. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 1 mile west of Crockerhill is Knowle Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Wherever a school like The Henry Cort Community College has ducted ventilation, a half-term visit keeps the work out of lesson time. Knowle Hospital, about 1 mile west, is the nearest hospital to Crockerhill, and healthcare sites of every size need their supply air kept clean.
