AHU cleaning in Sway
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers heating and cooling coils, internal panels and drain trays, and people most often call us about air handling units with blocked filters and dirty coils holding back the airflow.
For a building near Sway, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
A written report with pictures follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What AHU cleaning can’t fix
It’s worth knowing the limits before booking:
- Ventilation that was badly designed in the first place
- Building management system faults
- Dirty ducts beyond the unit itself
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we will tell you honestly before you book.
Where we work

- Heating and cooling coils
- Filter sections
- Internal panels
- Drain trays
In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. Tell us about any gates, ladders or locked plant areas at your site near Sway when you book.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
- Dig out any earlier paperwork for the system
Getting a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Advice
Ventilation in Sway buildings
There are about 3 schools, colleges and universities and about 5 hotels, B&Bs and guest houses on the FSA’s food hygiene register across Sway and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Sway’s nearest hospital, Lymington New Forest Hospital, is about 2.9 miles south-east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you run an office near Sway station, its supply ductwork can gather dust for years before anyone looks inside. Healthcare buildings such as Lymington New Forest Hospital, about 2.9 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Sway, yours matters too. Classrooms and halls at schools such as St Luke's Church of England Primary School are easiest to work in when pupils are away.
Sway is about 3 miles north-west of Lymington, in Hampshire. Across the SO41 area, we cover AHU cleaning for commercial sites. Our area takes in 683 places across Hampshire, from busy centres to quieter spots. You can also see our page for Southampton, about 13 miles away.
We work across SO41 for AHU cleaning and the streets around it. Whether your site is on Station Road, Anderwood Drive and Cruse Close or a nearby road, our technicians can take on the work.

Between visits
Here’s the after-treatment advice, in brief:
- Change filters on schedule and log each change
- Make sure condensate is draining away
- Report musty smells from the vents right away
- Diary the inspection date recommended in the report
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
Managing agents and facilities teams in Sway
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.
How we price AHU cleaning
We quote each job individually. This is what makes a difference:
- A single visit or a regular plan
- The number of sites or systems
- When the work can happen, such as evenings, overnight or weekends
- Site rules, permits and inductions
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, ring 0345 646 2711 or email us for straight advice and a fixed quote.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- Detail shots of panels, filters and grilles
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
- Any symptoms, from odd noises to smells or leaks
We do not publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To get going, call 0345 646 2711, or send details by email.
What the work involves, part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. 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.
FAQs for Sway
Do you do school ventilation cleaning in Sway in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Sway. Just call us on 0345 646 2711, or send details by email with your term dates and we’ll plan around them.
Do you work in villages like Sway?
Yes, we work in villages as well as towns, and Sway is covered. Just mention lanes, gates or anything else about the site when you book.
Can you clean the AHU out of hours?
Yes, if daytime working is not practical. We plan the shutdown window with you.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Does the AHU have to be shut down for cleaning?
Yes, for the time we’re working on it. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
Do you give a certificate after the clean?
Yes, both a certificate and a report with photos. The report also suggests when the unit should next be inspected.
