Surrey · Air handling unit cleaning
AHU Cleaning in Seale
AHU cleaning across Seale and nearby, booked around your opening hours and finished with a written report and pictures.
- Plant that needs cleaning after a refit
- Air handling units with blocked filters
- Blocked condensate drains and slimy trays
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Diary the inspection date recommended in the report
- Note any water around the unit or leaks below it
- Keep the certificate and photo report with the plant records
- Don’t store bins or materials near the intake
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
AHU cleaning in Seale
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and send you a fixed quote, so you know where you stand. Typical jobs include air handling units due a clean after building work and dirty filters cutting the airflow, across supply and extract fans, filter sections and drain trays.
Somewhere as small as Seale, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

How it works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes from a few hours for a compact unit to a day or more for a large one. If the van will struggle with a lane or gateway near Seale, let us know and we will plan around it.
- 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.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Let us know about parking and loading
- Have your last certificate or report to hand
- Move anything stored near the system

- Breakdowns that need a mechanical engineer
Not sure which it is? You can call us on 0345 646 2711 or email us and we will tell you honestly.

In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Seale questions
Can you come to Seale after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Can you get to a site in Seale?
Yes. Villages and rural sites across the South East are part of our work, Seale included. Let us know about access, parking and anything unusual about getting there when you book.
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 will advise on what to do next.
Does the AHU have to be shut down for cleaning?
Yes, for the time we are working on it. We can work evenings, overnight or at weekends to keep disruption down.
Where does the waste go?
We take it away when we go. While we work, it’s kept contained to keep the area clean.
How do you protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Is a quote from pictures possible?
Yes, where the pictures show enough. If not, a site survey comes first, and the quote follows that.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
What happens if it’s left?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. It’s simpler to plan the work at Seale now than to arrange it in a hurry later.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.

What the work involves, part by part
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
AHU cleaning in Seale: local notes
Food Standards Agency records list about 6 schools, colleges and universities and about 5 caring premises (care homes, nurseries and hospitals) registered as food businesses within 1.5 miles or so of the middle of Seale. Busy, occupied buildings like these are where clean supply air matters most. For Seale, the closest hospital is Guildford Hospital, roughly 4.8 miles east. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. About 33 miles out from central London, Seale is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you.
Healthcare ventilation, from large hospitals like Guildford Hospital (about 4.8 miles east) to small clinics, depends on clean filters, coils and ducts. Wherever a school like St Paul's CofE Infant School & Nursery has ducted ventilation, a half-term visit keeps the work out of lesson time.

Fixed quotes for AHU cleaning in Seale
Every site gets its own quote. This is what makes a difference:
- The scale of the work
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- The condition of the system
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.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- Any previous report or certificate
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room

Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
