AHU cleaning in Cranmore, done properly
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. We are often asked to deal with blocked condensate drains and slimy trays and odours coming through the supply air, on dampers and louvres, drain trays and heating and cooling coils.
Work in a small place like Cranmore starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
Why act early in Cranmore
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Our emergency line runs 24/7, but a planned visit to Cranmore is calmer for everyone.
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or send us an email, and we will explain what it covers.

FAQs for Cranmore
Is Cranmore within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Cranmore included. Just mention lanes, gates or anything else about the site when you book.
Can you work in Cranmore outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in Cranmore does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Which accreditations do you hold?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
How do you protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
How long does it take to clean an air handling unit?
Expect it to take half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Signs you need AHU cleaning in Cranmore
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Look out for these warning signs:
- Dirty coils holding back the airflow
- Intake sections clogged with outdoor debris
- Dirty fans and fan housings
- Air handling units with blocked filters
School buildings such as Shalfleet Church of England Primary School are usually done in the holidays, so classrooms aren’t disturbed.
What to look for in a quote
- Whether they’re fully insured
- If they look at the system before pricing
- Whether inaccessible sections are listed on the report
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

What else we do in Cranmore
The process
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes from a few hours for a compact unit to a day or more for a large one. A few photos of the system help us make the most of a visit to a place like Cranmore.
- 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.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Find the previous report, if there is one
- Clear loose items from the work area
- Mention any sign-in, permit or induction we need
Getting a quote
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. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
What the work involves, part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
What a clean won’t put right
Before you book, it helps to know what’s not included:
- Controls and BMS settings that run the unit
- Damaged coils beyond cleaning
- Ductwork downstream of the unit, which is a separate clean
If you’re not sure, just ring 0345 646 2711 or email us and we will give you a straight answer.
