About our AHU cleaning in Dorchester
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 air handling units never cleaned inside and leaves and litter drawn into the unit, we can put it right.
For a building in or near Dorchester, 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.
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’re fully insured.

Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
What the work involves, part by part
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
When it’s something else
In fairness, there are a few things this work will not fix:
- Mechanical faults with motors, belts or bearings
- The supply and extract ducts, quoted separately
- Airflow problems caused by the system’s design
If you are not sure, just call 0345 646 2711, or send details by email and we will give you a straight answer.

- Supply and extract fans
- Internal panels
- Drain trays
- Dampers and louvres

The process
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. The work itself takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Dorchester before we set off.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Let us know about permits to work or site inductions
- Make sure equipment near the work can be switched off and left to cool
- Let us know about parking and loading

Between visits
Results last longer with the right care. Here’s what we suggest:
- Do not ignore odours coming through the grilles
- Keep filter changes on time and recorded
- Book the next check in line with the report
- Keep the certificate and photo report with the plant records
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Why it’s worth doing now in Dorchester
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. It’s simpler to plan the work at Dorchester now than to arrange it in a hurry later.
