AHU cleaning in Charcott, done properly
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from photos or a site visit, and send you a fixed quote before any cleaning starts. The work covers internal panels, supply and extract fans and filter sections, and people most often call us about air handling units due a clean after building work and drain trays holding standing water.
For a building in or near Charcott, access is agreed in advance and the visit is planned around the journey.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

FAQs for Charcott
Do you cover smaller places like Charcott?
Yes, Charcott is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Do you work at weekends in Charcott?
Yes, out-of-hours work is a big part of what we do. It means the site in Charcott keeps running as normal. Just phone us on 0345 646 2711, or email photos with your opening times and we’ll plan around them.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can survey both on the same visit.
What about areas you cannot get to?
Anything we can’t reach goes on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
Is a quote from pictures possible?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded for your maintenance team to follow up.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
Different parts, different methods
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.

What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
When something else is needed
A few issues sit outside what this work can do:
- Faulty motors, drives or bearings
- Damaged coils beyond cleaning
- Problems with the unit’s controls or sensors
If you are not sure, just call us on 0345 646 2711 or send us an email and we will give you a straight answer.

Multi-site and managed buildings
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
How the visit works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes from a few hours for a compact unit to a day or more for a large one, and the area is cleaned down before we leave. Rural roads and tight entrances are worth telling us about before a visit to Charcott.
- 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.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Clear the space around the work
- Mention any locked doors, roof access or ceiling voids
- Dig out any earlier paperwork for the system
Ask for a quote
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. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Aftercare tips
Results last longer with the right care. We suggest:
- Keep the certificate and photo report with the plant records
- Make sure condensate is draining away
- Book the next check in line with the report
- Stick to the filter change plan
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
