AHU cleaning in Blackmoor, done properly
If the units serving a building in Blackmoor have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. The work covers filter sections, heating and cooling coils and drain trays, and the jobs we see most are filters that are clogged or overdue and fan sections that haven’t been cleaned in years.
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.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. 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.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.

Blackmoor: your questions answered
Is Blackmoor within the area you cover?
Yes. Blackmoor 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.
Is Blackmoor in your area for AHU cleaning?
Yes, Blackmoor is covered. You can ring 0345 646 2711, or email photos and tell us what needs doing.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
What if parts of the system can’t be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
Do you work evenings or weekends?
Yes. We work evenings, overnight and weekends, so the building keeps running in the day.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
Part by part
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
When to call us in Blackmoor
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
Signs it’s time to call us include:
- Blocked condensate drains and slimy trays
- Plant that has been serviced but not cleaned
- Intake sections clogged with outdoor debris
- Rooms that smell stuffy when the system runs
Classrooms and halls at schools such as St Matthew's Church of England Aided Primary School are easiest to work in when pupils are away.

What affects the cost of AHU cleaning
The survey tells us what the work involves. The main factors are:
- Access, including roofs, risers and ceiling voids
- The number of sites or systems
- One-off work versus a regular cycle
- Site rules, permits and inductions
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.
What we need to know
When you contact us, it’s useful to have:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
- Your opening hours and when the area is out of use
- Close-ups of filters, grilles, hatches or access panels
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.

Why act early in Blackmoor
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. A fault that closes a site in a village like Blackmoor affects everyone who depends on it.
