AHU cleaning around Langstone
Food Standards Agency data includes about 4 schools, colleges and universities, about 20 hospitals, care homes and childcare premises and about 3 hotels, B&Bs and guest houses in and around Langstone, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Langstone’s nearest hospital, Havant War Memorial Hospital, is about 1.1 miles north. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. At about 60 miles from central London, Langstone sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you.
Classrooms and halls at schools such as Bosmere Junior School are easiest to work in when pupils are away.

About our AHU cleaning in Langstone
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. Typical jobs include rooms that smell stuffy when the system runs and debris and leaves in the fresh air intake, on heating and cooling coils, dampers and louvres and internal panels.
For a building in or near Langstone, 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.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Questions from Langstone
Can the work in Langstone be done at night or at weekends?
Yes, nights and weekends are routine for us. That way a site in Langstone does not have to lose a day’s trading. Let us know the hours you’re closed and we’ll book within them.
Do you clean school ventilation in Langstone in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Langstone. Just phone us on 0345 646 2711 or use the quote form with your term dates and we will plan around them.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.
Is a quote from photos possible?
Normally, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we typically come back within one working day. If photos are not enough, we will survey first.
Do you have a 24/7 line?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
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.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
When to call us in Langstone
Whatever surrounds a building in Langstone, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Keep an eye out for these warning signs:
- Coils clogged with dust and debris
- Dust built up on fan impellers
- Debris and leaves in the fresh air intake
- Air handling units never cleaned inside
Healthcare buildings such as Havant War Memorial Hospital, about 1.1 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Langstone, yours matters too.

Different parts, different methods
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Store the TR19 paperwork where auditors can find it
- Keep inspection doors on the unit in good order
- Make sure condensate is draining away
- Flag stale or damp smells in the supply air
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
What happens on the day
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. A few pictures of the system help us make the most of a visit to a place like Langstone.
- 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.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Let us know about permits to work or site inductions
- Allow time for equipment near the work to be turned off and cool down

Advice
What affects the quote in Langstone
Every site gets its own quote. These are the things that affect it:
- Working hours and out-of-hours timing
- Whether we need access equipment or extra panels
- Whether several sites go on one quote
- Site requirements such as sign-in and permits
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.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
- Wide pictures of the system and the area around it
- The postcode and the type of business
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before any work starts.

Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
