Hampshire · Air handling unit cleaning
Swanwick AHU cleaning
One call covers cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Swanwick: survey, fixed quote, work and sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Dust built up on fan impellers
- Blocked condensate drains and slimy trays
- Units that have only ever had filter changes
How the visit works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. If the van will struggle with a lane or gateway near Swanwick, let us know and we’ll plan around it.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use
How to get 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 photos, get a survey first. Either way, the quote is fixed before any work is booked.

AHU cleaning in Swanwick
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers filter sections, dampers and louvres and internal panels, and common reasons people get in touch are plant that needs cleaning after a refit and dirty fans and fan housings.
Work in a small place like Swanwick starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Every visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

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 need training, the right equipment and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Swanwick questions
Do you work at weekends in Swanwick?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Swanwick needn’t be disturbed. Your opening times are the first thing we ask for.
Is Swanwick within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Swanwick included. A survey first, from pictures or a visit, means we arrive with the right kit.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
What types of premises do you cover?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll normally reply within one working day.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
How the job changes from site to site
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.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Look at the condensate drain whenever the unit is serviced
- Store the TR19 paperwork where auditors can find it
- Do not ignore odours coming through the grilles
- Keep inspection doors on the unit in good order
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
What we are called out for in Swanwick
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Most sites get in touch after spotting something like this:
- Condensate trays that will not empty
- Dirty fans and fan housings
- Coils clogged with dust and debris
- Stale or musty smells from the ventilation
Classrooms and halls at schools such as Sarisbury Church of England Junior School are easiest to work in when pupils are away.
Questions to ask before booking
- Proof of insurance
- Whether VAT is included
- Whether the quote is based on a survey or pictures
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

What else we do in Swanwick
For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Ventilation in Swanwick buildings
Food Standards Agency records list about 9 schools, colleges and universities and about 22 hospitals, care homes and childcare premises registered as food businesses in Swanwick and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 0.9 miles south of Swanwick is Coldeast, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
Coldeast, about 0.9 miles south, is the nearest hospital to Swanwick, and healthcare sites of every size need their supply air kept clean. If you run an office near Bursledon station, its supply ductwork can gather dust for years before anyone looks inside.

Why deal with it now?
Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. In a small place like Swanwick, a system that fails can take a site out of use.
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and why the quote is fixed before work begins.
