Air handling unit cleaning in Swaythling, Southampton
For cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Swaythling, one call is all it takes: survey, fixed quote, work and sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Units needing a clean before a new tenant or handover

- Dirty coils holding back the airflow
Common problems we fix in Swaythling
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that is where slime and odours start.
These are the problems we see most often:
- Rooms that smell stuffy when the system runs
- Dirty fans and fan housings
- Condensate trays that will not empty
- Filters that are clogged or overdue
Hospitals such as Royal South Hants Hospital (about 2 miles south) show how much a building can rely on clean ventilation, and smaller healthcare sites near Swaythling are no different.
Questions to ask before you book
- What’s included in the scope, part by part
- Whether the work can be done while the site is closed
- Whether VAT is included
- Proof of insurance
AHU cleaning for kitchens and businesses in Swaythling
Our AHU cleans for sites in Swaythling cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you’re dealing with debris and leaves in the fresh air intake and stale or musty smells from the ventilation, we can help, from internal panels, dampers and louvres and filter sections onwards.
Visits to a place like Swaythling are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

The process
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes half a day to a full day per unit, with large plant planned over several shifts. We plan the journey to Swaythling and bring what the job is likely to need.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear the space around the work
- Name a contact who can let us in at the agreed time
How to get a quote
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.

What else we do in Swaythling
What AHU cleaning looks like in Swaythling
Food Standards Agency records list about 24 schools, colleges and universities, about 18 caring premises (care homes, nurseries and hospitals) and about 3 hotels and guest houses registered as food businesses within about 1.5 miles of central Swaythling. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. For Swaythling, the closest hospital is Royal South Hants Hospital, roughly 2 miles south. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
If you manage shops or offices close to Swaythling station, a TR19® Air inspection shows whether the ductwork needs cleaning. School buildings such as Mansbridge Primary School are usually done in the holidays, so classrooms aren’t disturbed.
Swaythling is about 2 miles north of Southampton, in Southampton. Wherever you are in the SO16 postcode area, we can take on AHU cleaning. We cover 40 places across Southampton, large and small.
Our technicians cover all of the SO16, SO18 and SO17 postcode area for AHU cleaning and the streets around it. You’ll find streets such as High Road, Wide Lane and Lilac Road, all of which we cover for AHU cleaning. Other places close to Swaythling include Bassett Green (1 mile west), Mansbridge (1 mile east), North Stoneham (1 mile north), Portswood (1 mile south-west) and St Denys (1 mile south). Further out, we also cover Shirley (3 miles south-west), Regents Park (3 miles south-west), Thornhill (3 miles south-east), Itchen (3 miles south), Sholing (3 miles south) and Maybush (3 miles west).
Local landmarks in Swaythling
We work in commercial kitchens and buildings around Saint George Catholic Voluntary Aided College Southampton, Riverside Park and Saint George Catholic Voluntary Aided College Southampton and the streets around them. Swaythling has its own railway station: Swaythling station. A little further out are Marlands Shopping Centre (2.6 miles south-west) and Bitterne Local History Society Heritage And Research Centre (1.9 miles south). Green spaces nearby include Netley Common.
Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Note any water around the unit or leaks below it
- Keep the area around the fresh air intake clear
- Report stiff or damaged access doors
- Change filters on schedule and log each change
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Facilities teams in offices, schools and healthcare sites book us too in Swaythling and across Southampton. Work can be phased by floor, building or site to keep disruption down.
When something else is needed
In fairness, there are a few things this work will not fix:
- Ventilation that was badly designed in the first place
- Faulty motors, drives or bearings
- Dirty ducts beyond the unit itself
If in doubt, call us on 0345 646 2711, or email photos and we’ll say what we think.
What the work covers
- Dampers and louvres
- Filter sections

What affects the quote in Swaythling
There’s no set price list, because no two systems are the same. What we look at:
- The number of sites or systems
- How easy every part is to reach
- How big the system is
- Where the site is and how we reach it
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
What to send for a quote
You don’t need the technical terms. Just send:
- A few general shots of the system
- Your opening hours and when the area is out of use
- Any access panels or hatches you can see
- Where the plant sits or the system leaves the building, such as a roof or outside wall
For a fixed quote, call 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You’ll typically have a quote within one working day.
Questions from Swaythling
Do you do school ventilation cleaning in Swaythling in the summer holidays?
Yes. The holidays are the usual time for school work. With about 24 schools and colleges on the FSA’s register within roughly a mile and a half of Swaythling, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Is Swaythling within the area you cover?
Yes. Swaythling is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Do you have a 24/7 line?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we will quote them together.
How often should an air handling unit be cleaned?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
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.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Can you quote from pictures?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. Booking ahead lets us plan the trip to Swaythling at a time that suits you.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
