AHU cleaning in Tolleshunt D'Arcy
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers supply and extract fans, internal panels and drain trays, and common reasons people get in touch are dirty coils holding back the airflow and debris and leaves in the fresh air intake.
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.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Pictures of the system and its access let us plan the work in Tolleshunt D'Arcy before we set off.
- We look at the unit and the plant area during the survey.
- 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.
Getting ready for the visit
- Tell us where we can park and unload
- Find the previous report, if there is one

Aftercare tips
To keep the system working properly between visits:
- Look at the condensate drain whenever the unit is serviced
- File each AHU report in the maintenance log
- Keep the area around the fresh air intake clear
- Change filters on schedule and log each change
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
When to call us in Tolleshunt D'Arcy
Whatever surrounds a building in Tolleshunt D'Arcy, 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.
Most sites get in touch when they notice something like this:
- Dirty filters cutting the airflow
- Dust-coated heating and cooling coils
- Stale or musty smells from the ventilation
- Plant that needs cleaning after a refit
In Tolleshunt D'Arcy, we look inside the system before deciding what needs cleaning.

Your questions about AHU cleaning in Tolleshunt D'Arcy
Do you work at weekends in Tolleshunt D'Arcy?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just phone us on 0345 646 2711 or send us an email with your opening times and we’ll plan around them.
Can you get to a site in Tolleshunt D'Arcy?
Yes. Tolleshunt D'Arcy is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. At the end, the area is cleaned down.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
How long does an AHU clean take?
Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, so ring 0345 646 2711 or use the quote form to talk it through.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
What do you do with what you remove?
We take it away when we go. During the work, it’s contained to keep the area clean.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
What the work involves, part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. With notice, the visit to Tolleshunt D'Arcy can be fitted around your bookings and events.
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
