AHU cleaning in Norton Ash
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. We’re often asked to deal with drain trays holding standing water and units needing a clean before a new tenant or handover, across heating and cooling coils, dampers and louvres and filter sections.
For a building in or near Norton Ash, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Each visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Do not ignore odours coming through the grilles
- Report stiff or damaged access doors
- Book the next check in line with the report
- Store the TR19 paperwork where auditors can find it
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Honest limits
We’d rather tell you now than book work that will not help, so here are the limits:
- Dirty ducts beyond the unit itself
- Building management system faults
- Faulty motors, drives or bearings
Not sure which it is? You can phone us on 0345 646 2711 or email us and we will tell you honestly before you book.

Signs you need AHU cleaning in Norton Ash
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.
It’s time to book a visit if you see:
- Units needing a clean before a new tenant or handover
- Blocked condensate drains and slimy trays
- Filters that are clogged or overdue
- Odours coming through the supply air
Wherever a school like Teynham Parochial Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What the work involves, part by part
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
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.
Leave it or put it right?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. In a small place like Norton Ash, a system that fails can take a site out of use.
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 play a part.

What affects the quote in Norton Ash
A fixed price needs a few facts first. We look at:
- Site requirements such as sign-in and permits
- One-off work versus a regular cycle
- The condition of the system
- How big the system is
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
What to send for a quote
Before you ask for a quote, gather:
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your last certificate, test record or report
- Wide pictures of the system and the area around it
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

The process

Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. On site, it takes one overnight shift for many single units, with bigger plant phased. The timing of a visit to Norton Ash 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.
- We sheet the area and the unit is isolated.
- 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.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Tell us about site rules, permits or sign-in
- Tell us the best time to work, such as after service or at a weekend
