How we handle AHU cleaning in Cold Ash
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you have coils clogged with dust and debris and blocked condensate drains and slimy trays, we can help.
Somewhere as small as Cold Ash, ducted ventilation is usually 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.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
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.
Managing agents and facilities teams in Cold Ash
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Honest limits
It’s worth knowing the limits before booking:

Signs you need AHU cleaning in Cold Ash
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Signs it’s time to call us include:
- Blocked condensate drains and slimy trays
- Dirty filters cutting the airflow
- Plant that needs cleaning after a refit
- Plant that has been serviced but not cleaned
Wherever a school like Cold Ash St Mark's C.E. School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What we do, step by step
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. A quick note on how to find the site and where to park makes a visit to Cold Ash run smoothly.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Let us know about permits to work or site inductions
- Let us know about parking and loading
- Have your last certificate or report to hand

The quickest way to a quote is to send pictures: 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.
Advice
Why deal with it now?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. Out of sight is the usual reason a rural system goes too long without attention.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
What you get with us
- Photo reports with every job
- We diagnose before we treat
- One number for every site across the South East and London
- CHAS and SafeContractor accredited, with ISO 9001
