AHU cleaning for kitchens and businesses in Henton
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. Common call-outs are for drain trays holding standing water and air handling units never cleaned inside, across heating and cooling coils, filter sections and drain trays.
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.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

What we’re called out for in Henton
Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Any of these means the system needs a check-up:
- Plant that has been serviced but not cleaned
- Leaves and litter drawn into the unit
- Air handling units with blocked filters
- Dirty coils holding back the airflow
Thame Community Hospital, about 3.6 miles north-west, is the nearest hospital to Henton, and healthcare sites of every size need their supply air kept clean.

For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.

Your questions about AHU cleaning in Henton
Do you work in villages like Henton?
Yes. Villages and rural sites across the South East are part of our work, Henton included. The journey is planned ahead, so a few details about the route help.
Can you do AHU cleaning in Henton?
Yes, Henton is within the area we cover across London and the South East. Just call us on 0345 646 2711, or send details by email with a few details of the site.
What happens if you can’t reach some of it?
We record them 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 do you do with what you remove?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We don’t leave it behind.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
Do you work evenings or weekends?
Yes, wherever it helps the building. Tell us when the unit can go off and we will work to that.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
The process
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. Photos of the system and how to reach it help us plan a visit to Henton.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
How to prepare
- Tell us where we can park and unload
- Clear the space around the work
- Let us know when the site is closed or quiet
