In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
AHU cleaning in Thorncross
We clean air handling units for buildings in Thorncross and across the Isle of Wight, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you have dirty fans and fan housings and intake sections clogged with outdoor debris, we can put it right, from supply and extract fans, drain trays and internal panels onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- How many systems or sites are involved
- Site requirements such as sign-in and permits
- The size of the system
- What state the system is in
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
What to send for a quote:
- Where the site is and what kind of site it is
- The times we could work without disrupting the site
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
Between visits
To keep the system working properly between visits:
- Keep inspection doors on the unit in good order
- Plan the next inspection before the last report gets filed away
- Keep the certificate and photo report with the plant records
- Note any water around the unit or leaks below it
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
What the work involves, part by part
Internal casing and panels
We open each section through its doors and close them securely when we are done, and check every one is shut.
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with pictures so you can decide on any repairs.
Questions from Thorncross
Do you work at weekends in Thorncross?
Yes, we can come after you close and finish before you open. That way a site in Thorncross does not have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Do you cover Thorncross for AHU cleaning?
Yes. Our area runs across London and the South East, Thorncross included. Get in touch with the details and we will arrange a survey.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it does not spread.
What do you need from me for a quote?
A short description and a few pictures, with the address and opening hours. We’ll ask for anything else we need.
How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes from a few hours for a compact unit to a day or more for a large one. Pictures of the system and its access let us plan the work in Thorncross before we set off.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Move anything stored near the system
- Allow time for equipment near the work to be turned off and cool down
- Make sure someone can let us in and lock up afterwards
Get a fixed quote
We do not publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, phone us on 0345 646 2711, or email photos.
Advice
When to call us in Thorncross
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
If you notice any of these, it’s worth a diagnosis:
- Fan sections that haven’t been cleaned in years
- Air handling units with blocked filters
- Dirty coils holding back the airflow
- Units needing a clean before a new tenant or handover
If you run a surgery, dental practice or care home near Thorncross, clean ventilation matters as much to you as to a hospital like Whitecroft Hospital (about 4.4 miles north-east).
Before you book anyone
- Whether the work can be done while the site is closed
- Whether inaccessible sections are listed on the report
- When the next visit should be, and why
- Whether they’re fully insured
Thorncross buildings and their air
Thorncross’s nearest hospital, Whitecroft Hospital, is about 4.4 miles north-east. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Wherever a school like Brighstone Church of England Aided Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Why act early in Thorncross
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Thorncross simpler. In a small place like Thorncross, a system that fails can take a site out of use.
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and the price is agreed before work begins.
