Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
About our AHU cleaning in Eynsford
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you are dealing with dirty fans and fan housings and odours coming through the supply air, we can put it right.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What else we do in Eynsford
Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Plan the next inspection before the last report gets filed away
- Keep the certificate and photo report with the plant records
- Watch for drips or damp patches near the plant
- Do not store bins or materials near the intake
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
AHU cleaning in Eynsford: local notes

Darenth Park Hospital is the nearest hospital, about 5.1 miles north-east of Eynsford. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.

For schools like The Anthony Roper Primary School, the holidays are the usual time to inspect and clean ventilation.

Different parts, different methods
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
What a clean won’t put right
Before you book, it helps to know what’s not included:
- Faulty motors, drives or bearings
- Controls and BMS settings that run the unit
- The supply and extract ducts, quoted separately
Not sure which it is? You can give us a ring on 0345 646 2711 or use the quote form and we will tell you honestly before you book.
Parts of the system we cover
- Supply and extract fans
- Heating and cooling coils
- Drain trays
- Filter sections
- Internal panels
- Dampers and louvres
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
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.
How it works
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes one overnight shift for many single units, with bigger plant phased, and the area is cleaned down before we leave. For a village or hamlet like Eynsford, tell us about narrow lanes, gates and parking when you book.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Arrange a key holder or contact on site
- Have your last certificate or report to hand
Get a fixed quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Related advice
Why it’s worth doing now in Eynsford
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. In a small place like Eynsford, a system that fails can take a site out of use.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, phone us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.

Do you do ventilation duct cleaning too?
