About our AHU cleaning in Roughdown
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. If you’re dealing with fan sections that haven’t been cleaned in years and units needing a clean before a new tenant or handover, we can help, from dampers and louvres, internal panels and filter sections onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Signs you need AHU cleaning in Roughdown
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
It’s time to book a visit if you see:
- Intake sections clogged with outdoor debris
- Plant that has been serviced but not cleaned
- Dirty fans and fan housings
- Rooms that smell stuffy when the system runs
If you manage a school such as Blackfield Primary School, ventilation cleaning is best booked for the holidays.

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Coils that are corroded or leaking and need replacing
- Airflow problems caused by the system’s design
- Faulty motors, drives or bearings
If in doubt, ring 0345 646 2711 or email us and we’ll say what we think before you book.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Your own staff can handle the daily basics: 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.
Managing agents and facilities teams in Roughdown
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
The process
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes one overnight shift for many single units, with bigger plant phased. The timing of a visit to Roughdown is set by you, and the travel is our side of the planning.
- 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.
- 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
- Let us know when the site is closed or quiet
- Find the previous report, if there is one
- Let us know how we reach the system, including roofs, risers and plant rooms
Ask for a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.

Roughdown: your questions answered
Do you cover smaller places like Roughdown?
Yes, Roughdown is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you work overnight in Roughdown?
Yes. We work evenings, overnight and at weekends. That way a site in Roughdown doesn’t have to lose a day’s trading. Just call 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Can you quote from photos?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and leave the area clean.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.
What does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.

Different parts, different methods
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
What happens if it’s left?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. In a place like Roughdown, ductwork and fans are easy to forget until something goes wrong.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
