How we handle AHU cleaning in Mount Pleasant
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. The work covers heating and cooling coils, dampers and louvres and supply and extract fans, and people most often call us about dust-coated heating and cooling coils and stale or musty smells from the ventilation.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

AHU cleaning in Mount Pleasant: local notes
The FSA’s food hygiene register lists about 5 schools, colleges and universities, about 4 care, childcare and hospital premises and about 6 hotels and B&Bs with registered kitchens or food service within roughly a mile and a half of the centre of Mount Pleasant. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Lymington New Forest Hospital is the nearest hospital, about 1.4 miles south-east of Mount Pleasant. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
School buildings such as Priestlands School are typically done in the holidays, so classrooms are not disturbed.
Mount Pleasant is about 2 miles north-west of Lymington, in Hampshire. Mount Pleasant gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with pictures. 683 places in Hampshire are on our list, from busy centres to quieter spots. We also work in Southampton, around 13 miles away.

What AHU cleaning can’t fix
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Ventilation that was badly designed in the first place
- Controls and BMS settings that run the unit
- Breakdowns that need a mechanical engineer
If you are not sure, just phone us on 0345 646 2711, or email photos and we’ll give you a straight answer before you book.
What the work covers
- Supply and extract fans
- Filter sections
- Drain trays
- Heating and cooling coils
- Internal panels
- Dampers and louvres
In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Flag stale or damp smells in the supply air
- Clear leaves and litter away from the intake
- Report stiff or damaged access doors
- Report water on the plant room floor
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
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.
What we do, step by step
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 anything from half a day for one small unit to several shifts for a plant room full of them. Photos of the system and how to reach it help us plan a visit to Mount Pleasant.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Arrange a key holder or contact on site
- Agree a time when the area can be out of use
- Find the previous report, if there is one
Getting a quote
To get a fixed quote, call us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We normally come back within one working day.

Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- The condition we find in the survey
- Site requirements such as sign-in and permits
- Where the site is and how we reach it
- When the work can happen, such as evenings, overnight or weekends
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before work begins.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- A few general shots of the system
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
The quickest way to a quote is to send pictures: 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.
Do you need AHU cleaning in Mount Pleasant?
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Signs it’s time to call us include:
- Stale or musty smells from the ventilation
- Air handling units due a clean after building work
- Intake sections clogged with outdoor debris
- Filters that are clogged or overdue
If you run a surgery, dental practice or care home near Mount Pleasant, clean ventilation matters as much to you as to a hospital like Lymington New Forest Hospital (about 1.4 miles south-east).
