AHU cleaning for kitchens and businesses in Mount Pleasant
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. If you have units that have only ever had filter changes and dirty fans and fan housings, we can put it right.
In a village or hamlet like Mount Pleasant, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Why deal with it now?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. With notice, the visit to Mount Pleasant can be fitted around your bookings and events.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, call us on 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.

What else we do in Mount Pleasant
For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
When it’s something else
Some problems need a different service or another trade:
- Building management system faults
- A system that’s undersized for the building
- Mechanical faults with motors, belts or bearings
If in doubt, ring 0345 646 2711 or drop us a line and we’ll say what we think.
Where we work
- Internal panels
- Supply and extract fans
- Heating and cooling coils
- Drain trays
- Filter sections
- Dampers and louvres
Part by part
Internal casing and panels
Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
AHU cleaning around Mount Pleasant
For Mount Pleasant, the closest hospital is Herts and Essex Hospital, roughly 4 miles south. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. About 31 miles out from central London, Mount Pleasant is part of the South East area we work across. The visit is fixed around your opening hours, not ours.
Classrooms and halls at schools such as Manuden Primary School are easiest to work in when pupils are away. If you run a surgery, dental practice or care home near Mount Pleasant, clean ventilation matters as much to you as to a hospital like Herts and Essex Hospital (about 4 miles south).

Between visits
Aftercare is simple, and it makes the next visit easier:
- Keep the certificate and photo report with the plant records
- Don’t store bins or materials near the intake
- Make sure the unit’s access doors open easily
- Look at the condensate drain whenever the unit is serviced
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
FAQs for Mount Pleasant
Can the work in Mount Pleasant be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. That way a site in Mount Pleasant doesn’t have to lose a day’s trading. When you call us on 0345 646 2711 or email us, mention when the site is quiet.
Is Mount Pleasant in your area for AHU cleaning?
Yes. Our area runs across London and the South East, Mount Pleasant included. Just call 0345 646 2711, or email photos with a few details of the site.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends to keep disruption down.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Do you offer emergency callouts?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
How long does an AHU clean take?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, out of hours if needed.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it does not spread.
What we do, step by step
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off.
