AHU cleaning in Landport
Where a building in Landport has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you have odours coming through the supply air and air handling units never cleaned inside, we can help, from supply and extract fans, internal panels and drain trays onwards.
Smaller buildings around Landport often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Different parts, different methods
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with photos.
When it’s something else
Before you book, it helps to know what’s not included:
- The supply and extract ducts, quoted separately
- Breakdowns that need a mechanical engineer
- Leaking heating or cooling coils
If you are not sure, just give us a ring on 0345 646 2711 or use the quote form and we’ll give you a straight answer before booking.
Where we work
- Supply and extract fans
- Internal panels
- Filter sections
- Drain trays
- Dampers and louvres
- Heating and cooling coils
What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What affects the cost of AHU cleaning
Your quote is based on your site. We consider:
- Whether we need access equipment or extra panels
- The scale of the work
- The condition we find in the survey
- One-off work versus a regular cycle
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Helping us quote
When you contact us, it’s useful to have:
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
- The postcode and the type of business
- A few general shots of the system
If you need AHU cleaning in Landport, call us on 0345 646 2711 or email us. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. A fixed quote normally follows within one working day.
Keeping the system healthy
To keep the system working properly between visits:
- Make sure condensate is draining away
- Report stiff or damaged access doors
- Book the next check in line with the report
- Keep the certificate and photo report with the plant records
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
Why deal with it now?
Stuffy rooms and stale smells in a building in Landport can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. Around Landport, a kitchen or building out of action is missed straight away.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or drop us a line, and we’ll talk you through it.

Questions from Landport
Can you work in Landport outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in Landport doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Can a school’s ventilation in Landport be done out of term time?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 37 schools, colleges and universities with registered kitchens within about a mile and a half of Landport. Just phone us on 0345 646 2711, or send details by email with your term dates and we will plan around them.
How much does AHU cleaning cost in Landport?
Every site is different, so each gets its own fixed quote. For a quote, phone us on 0345 646 2711 or drop us a line and tell us about the site and its opening hours.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
What about areas you can’t get to?
We record them on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
How long does an AHU clean take?
As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. The shutdown is planned to fit, out of hours if needed.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What AHU cleaning looks like in Landport
Going by the FSA’s register, there are about 37 schools, colleges and universities, about 41 care, childcare and hospital premises and about 17 hotels, B&Bs and guest houses serving food in and around Landport, up to about a mile and a half out. Busy, occupied buildings like these are where clean supply air matters most. Landport’s nearest hospital, Royal Portsmouth Hospital, is about less than half a mile south-west. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.

Hospitals such as Royal Portsmouth Hospital (about under half a mile south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Landport are no different.
