AHU cleaning in Potters Corner, done properly
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 are not flattened. The work covers dampers and louvres, drain trays and internal panels, and common reasons people get in touch are odours coming through the supply air and units that have only ever had filter changes.
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.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Questions from Potters Corner
Can you do AHU cleaning in Potters Corner?
Yes, Potters Corner is covered. You can call 0345 646 2711, or email photos and tell us what needs doing.
Do you work overnight in Potters Corner?
Yes, evening, overnight and weekend work is normal for us. It means the site in Potters Corner keeps running as normal. Just call us on 0345 646 2711 or email us with your opening times and we will plan around them.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.
Do you have a 24/7 line?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
What if parts of the system cannot be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Signs you need AHU cleaning in Potters Corner
Whatever surrounds a building in Potters Corner, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
It’s time to book a visit if you see:
- Leaves and litter drawn into the unit
- Odours coming through the supply air
- Condensate trays that will not empty
- Dust-coated heating and cooling coils
William Harvey Hospital, about 3.4 miles south-east, is the nearest hospital to Potters Corner, and healthcare sites of every size need their supply air kept clean.
What your quote should include
- How areas they can’t reach will be recorded
- Whether the quote shows VAT
- Which accreditations they hold, and whether you can check them
- Whether the work can be done while the site is closed
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Change filters on schedule and log each change
- Check the drain tray is emptying during routine visits
- Clear leaves and litter away from the intake
- Store the TR19 paperwork where auditors can find it
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.

Honest limits
We will not sell you work that doesn’t address the problem, so here are the limits:
- Ductwork downstream of the unit, which is a separate clean
- Leaking heating or cooling coils
- A system that is undersized for the building
Not sure which it is? You can call 0345 646 2711, or send details by email and we will tell you honestly before you book.
What we work on in Potters Corner
- Supply and extract fans
- Internal panels
- Drain trays
- Heating and cooling coils
- Dampers and louvres
- Filter sections
How the job changes from site to site
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Why deal with it now?
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Our emergency line runs 24/7, but a planned visit to Potters Corner is calmer for everyone.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before we start.

For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes half a day to a full day per unit, with large plant planned over several shifts. Rural roads and tight entrances are worth telling us about before a visit to Potters Corner.
- 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.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Arrange a key holder or contact on site
- Mention any parking or loading restrictions
