About our AHU cleaning in Penton Grafton
If the units serving a building in Penton Grafton have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. If you’re dealing with debris and leaves in the fresh air intake and drain trays holding standing water, we can put it right.
In a village or hamlet like Penton Grafton, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Do you need AHU cleaning in Penton Grafton?
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Look out for these warning signs:
- Odours coming through the supply air
- Units that have only ever had filter changes
- Dust built up on fan impellers
- Blocked condensate drains and slimy trays
Hospitals such as Andover War Memorial Hospital (about 1.7 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Penton Grafton are no different.

What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
The process
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. If the van will struggle with a lane or gateway near Penton Grafton, let us know and we will plan around it.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- 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
- Arrange a key holder or contact on site
- Find the previous report, if there is one
- Mention any sign-in, permit or induction we need

Penton Grafton questions
Do you cover Penton Grafton for AHU cleaning?
Yes. We work across London and the South East, and Penton Grafton is part of that. Get in touch with the details and we will arrange a survey.
Can you get to a site in Penton Grafton?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
Can you clean without disrupting the building?
Yes. We time the work to fit the building’s hours. In hospitals and care homes, we agree timings with the site team.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
How long does an AHU clean take?
It takes one overnight shift for many single units, with bigger plant phased. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Between visits
So the system stays in good health:
- Keep the area around the fresh air intake clear
- Store the TR19 paperwork where auditors can find it
- Change filters on schedule and log each change
- Flag stale or damp smells in the supply air
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. Somewhere as small as Penton Grafton, losing a kitchen or building to a fault is felt by everyone who uses it.
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
