About our AHU cleaning in Upper Kingston
We clean air handling units for buildings in Upper Kingston and across Hampshire, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We’re often asked to deal with dirty coils holding back the airflow and dirty fans and fan housings, across supply and extract fans, internal panels and heating and cooling coils.
Somewhere as small as Upper Kingston, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What the work involves, part by part
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
What else we do in Upper Kingston
What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before any work starts, and floors and nearby surfaces are sheeted. The work itself takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Upper Kingston before we set off.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.

Common questions in Upper Kingston
Will you come out to Upper Kingston?
Yes. Upper Kingston is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Do you work overnight in Upper Kingston?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
Can you quote from pictures?
Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. If pictures aren’t enough, we’ll survey first.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
Which sectors do you work in?
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.
What does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, usually ready within one working day.
What happens if it’s left?
If people in a building in Upper Kingston complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. In a place like Upper Kingston, ductwork and fans are easy to forget until something goes wrong.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before any work starts, so there are no surprises.

What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- The times the site is available
- The condition we find in the survey
- Site requirements such as sign-in and permits
- Access, including roofs, risers and ceiling voids
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before work begins.
What we need to know
Before you ask for a quote, gather:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
The quickest way to a quote is to send photos: 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 many jobs can be priced from that alone.

Between visits
Simple habits between visits make a real difference. Our advice:
- Diary the inspection date recommended in the report
- Check the drain tray is emptying during routine visits
- Don’t ignore odours coming through the grilles
- Keep filter changes on time and recorded
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
