How we handle AHU cleaning in St Helens
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers heating and cooling coils, dampers and louvres and internal panels, and people most often call us about leaves and litter drawn into the unit and dirty coils holding back the airflow.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Do you need AHU cleaning in St Helens?
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
Clients usually contact us after spotting something like this:
- Air handling units due a clean after building work
- Intake sections clogged with outdoor debris
- Drain trays holding standing water
- Dust-coated heating and cooling coils
Arthur Webster Memorial Hospital for Children, about 5.3 miles south-west, is the nearest hospital to St Helens, and healthcare sites of every size need their supply air kept clean.

What else we do in St Helens
St Helens questions
Can you get to a site in St Helens?
Yes. St Helens is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Do you work at weekends in St Helens?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Do you repair air handling units?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
How long does it take to clean an air handling unit?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
What should I send you?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then give us a ring on 0345 646 2711, or send details by email.
What happens if you cannot reach some of it?
Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
What happens on the day
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes from a few hours for a compact unit to a day or more for a large one. If the van will struggle with a lane or gateway near St Helens, let us know and we will plan around it.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Arrange a key holder or contact on site
- Mention any parking or loading restrictions
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Day-to-day cleaning is something your team can do: 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.
How the job changes from site to site
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Keeping the system healthy
So the system stays in good health:
- Look at the condensate drain whenever the unit is serviced
- Change filters on schedule and log each change
- Keep the certificate and photo report with the plant records
- Flag stale or damp smells in the supply air
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
