AHU cleaning in Havant
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. The work covers filter sections, internal panels and dampers and louvres, and the jobs we see most are dirty coils holding back the airflow and air handling units never cleaned inside.
Buildings in towns like Havant often have ventilation added in stages, with units on the roof or in a plant room. An inspection shows which parts need cleaning.
A written report with pictures follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How it works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a single shift for a typical unit, longer for large or heavily soiled ones. A closed day, an evening or an early start: whichever suits your site in Havant, we will book around it.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Find the previous report, if there is one
- Let us know about permits to work or site inductions
- Agree a time when the area can be out of use

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Watch for drips or damp patches near the plant
- Flag stale or damp smells in the supply air
- Keep inspection doors on the unit in good order
- Change filters on schedule and log each change
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
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.
Havant: your questions answered
Can you come to Havant after we close?
Yes, we can come after you close and finish before you open. The work in Havant can fit around your hours. Your opening times are the first thing we ask for.
Do you do school ventilation cleaning in Havant in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Havant, the Food Standards Agency lists about 7 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Does the AHU have to be shut down for cleaning?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Is Havant in your area?
Yes. Our technicians work in Havant, as part of our area across London and the South East.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Call us any time and explain what’s happened.
How long does it take to clean an air handling unit?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, out of hours if needed.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What do you need from me for a quote?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply ring 0345 646 2711, or email photos.
Do you need AHU cleaning in Havant?
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Keep an eye out for these warning signs:
- Fan sections that haven’t been cleaned in years
- Units needing a clean before a new tenant or handover
- Dirty coils holding back the airflow
- Odours coming through the supply air
Classrooms and halls at schools such as Trosnant Infant School are easiest to work in when pupils are away.
Questions to ask before booking
- What happens if part of the system cannot be accessed
- Whether the quote is based on a survey or pictures
- What’s included in the scope, part by part
- When they can work, and whether that is outside your opening hours
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
What the work involves, part by part
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey so the quote reflects it.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. Nothing in a duct, damper or fan improves by being left.
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 unsure, phone us on 0345 646 2711 or email us and we will give you an honest view and a fixed quote.
