How we handle AHU cleaning in Hartley Mauditt
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and give you a fixed quote before any cleaning starts. Common call-outs are for debris and leaves in the fresh air intake and air handling units due a clean after building work, across internal panels, dampers and louvres and heating and cooling coils.
Somewhere as small as Hartley Mauditt, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
We’ve been trading since 2009, as 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 affects the quote in Hartley Mauditt
We do not publish a price list, because sites vary so much. The quote depends on:
- Whether several sites go on one quote
- Travel, parking and unloading
- Site rules, permits and inductions
- Access, including roofs, risers and ceiling voids
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.
What to send for a quote
We can often survey from photos. The most useful are:
- The roof, plant room or outside wall the system runs to
- Wide photos of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

FAQs for Hartley Mauditt
Can you do AHU cleaning in Hartley Mauditt?
Yes, we work in Hartley Mauditt and the places around it. A fixed quote usually follows within one working day of the survey details.
Can you come to Hartley Mauditt after we close?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Hartley Mauditt needn’t be disturbed. Your opening times are the first thing we ask for.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
Can you quote from photos?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote normally follows within one working day. If pictures aren’t enough, we will survey first.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.
When should our AHU next be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
Can you come out in an emergency?
Yes. There’s a 24/7 emergency line, for problems that can’t wait. Ring any time and tell us what’s happened.

What the work involves, part by part
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
What happens if it’s left?
Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. A fault that closes a site in a village like Hartley Mauditt affects everyone who depends on it.
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before any work starts.

Do you need AHU cleaning in Hartley Mauditt?
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
These are the problems we see most often:
- Air handling units with blocked filters
- Debris and leaves in the fresh air intake
- Dirty coils holding back the airflow
- Dirty fans and fan housings
For buildings in and around Hartley Mauditt, TR19® Air cleaning starts with an inspection.

What your team can do, and what needs us
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Store the TR19 paperwork where auditors can find it
- Do not ignore odours coming through the grilles
- Report stiff or damaged access doors
- Keep filter changes on time and recorded
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
