AHU cleaning in Woolston
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. We’re often asked to deal with dust-coated heating and cooling coils and plant that needs cleaning after a refit, on dampers and louvres, heating and cooling coils and filter sections.
For a building near Woolston, the visit is planned around how it’s used, and the journey is planned ahead. The method doesn’t change: inspect first, clean, then record what was done.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Why act early in Woolston
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. That makes the next inspection of a building in Woolston simpler. You choose the date of a planned visit, and a breakdown never asks.
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711 or send us an email, and we’ll talk you through it.

How the visit works
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Tell us when your site near Woolston is quiet and the visit will be booked for then.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Let us know about parking and loading
- Let us know about permits to work or site inductions
- Find the previous report, if there is one

Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Woolston’s nearest hospital, Royal South Hants Hospital, is about 1.6 miles north-west.

It takes one overnight shift for many single units, with bigger plant phased. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.

Common problems we fix in Woolston
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
What we are most often called out for:
- Plant that needs cleaning after a refit
- Rooms that smell stuffy when the system runs
- Air handling units never cleaned inside
- Fan sections that haven’t been cleaned in years
For workplaces around Woolston station with mechanical ventilation, cleaning can be done in the evening or at weekends.

Different parts, different methods
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
