Why act early in Dunn Street
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. It’s worth booking a check, because nobody sees inside a duct day to day.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

How we handle AHU cleaning in Dunn Street
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you are dealing with filters that are clogged or overdue and fan sections that haven’t been cleaned in years, we can put it right, from filter sections, supply and extract fans and heating and cooling coils onwards.
In a village or hamlet like Dunn Street, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Look at the condensate drain whenever the unit is serviced
- Report stiff or damaged access doors
- Keep filter changes on time and recorded
- Watch for drips or damp patches near the plant
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.
Honest limits
Before you book, it helps to know what’s not included:
- The supply and extract ducts, quoted separately
- Airflow problems caused by the system’s design
- Faulty motors, drives or bearings
If you’re not sure, just call us on 0345 646 2711 or email us and we will give you a straight answer before you book.
What we work on in Dunn Street
- Internal panels
- Drain trays
- Dampers and louvres
- Supply and extract fans
- Heating and cooling coils

The process
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes from a few hours for a compact unit to a day or more for a large one. Rural roads and tight entrances are worth telling us about before a visit to Dunn Street.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions

When to call us in Dunn Street
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Clients typically contact us when they notice something like this:
- Stale or musty smells from the ventilation
- Intake sections clogged with outdoor debris
- Dirty filters cutting the airflow
- Plant that needs cleaning after a refit
School buildings such as Swingate Primary School are typically done in the holidays, so classrooms aren’t disturbed.
