What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
How we handle AHU cleaning in Fawley
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. We are often asked to deal with dust-coated heating and cooling coils and stale or musty smells from the ventilation, on internal panels, dampers and louvres and drain trays.
For a building in or near Fawley, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What affects the cost of AHU cleaning
We quote each job individually. These are the things that affect it:
- The condition we find in the survey

- Whether we need access equipment or extra panels
- Site requirements such as sign-in and permits
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before we start.

To speed up the quote, please include:
- Wide pictures of the system and the area around it

Leave it or put it right?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. A planned visit to Fawley is easier to arrange than an emergency callout.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, call 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

Common questions in Fawley
Can you do AHU cleaning in Fawley?
Yes, we work in Fawley and the places around it. To start, give us a ring on 0345 646 2711 or email us with a few photos of the system.
Can you work in Fawley outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Fawley keeps running as normal. Let us know the hours you are closed and we’ll book within them.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that can’t wait until a planned visit. Ring any time and tell us what’s happened.
Do you clean the ductwork as well?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can quote for both.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.

Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Plan the next inspection before the last report gets filed away
- File each AHU report in the maintenance log
- Make sure the unit’s access doors open easily
- Report musty smells from the vents right away
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Different parts, different methods
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.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
When to call us in Fawley
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
If you notice any of these, it’s worth a diagnosis:
- Dust built up on fan impellers
- Dirty filters cutting the airflow
- Dust-coated heating and cooling coils
- Leaves and litter drawn into the unit
Healthcare buildings such as Marlow Community Hospital, about 5.8 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Fawley, yours matters too.
What your quote should include
- How areas they can’t reach will be recorded
- What paperwork you get at the end
- How they set the interval to the next visit
- Whether a survey comes first
The process
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Fawley before we set off.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Clear the space around the work
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in
