AHU cleaning in Denton
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from pictures or a site visit, and send you a fixed quote, so you know where you stand. Typical jobs include dirty filters cutting the airflow and dust built up on fan impellers, on supply and extract fans, dampers and louvres and heating and cooling coils.
Somewhere as small as Denton, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Denton buildings and their air
Denton’s nearest hospital, NHS Oxfordshire Clinical Commissioning Group, is about 3.1 miles west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. About 47 miles out from central London, Denton is part of the South East area we work across. The visit is fixed around your opening hours, not ours.
For schools like Garsington Church of England Primary School, the holidays are the usual time to inspect and clean ventilation. If you run a surgery, dental practice or care home near Denton, clean ventilation matters as much to you as to a hospital like NHS Oxfordshire Clinical Commissioning Group (about 3.1 miles west).

Managing agents and facilities teams in Denton
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
Facilities teams in offices, schools and healthcare sites book us too in Denton and across Oxfordshire. Larger estates can be phased building by building around the people who use them.
What the work involves, part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
How it works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Photos of the system and how to reach it help us plan a visit to Denton.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
Getting ready for the visit
- Clear the space around the work
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Common questions in Denton
Do you offer AHU cleaning in Denton?
Yes, Denton is covered. Get in touch with the details and we’ll arrange a survey.
Will you come out to Denton?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Are you insured?
Yes, we are fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
Will the ventilation be off while you clean?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building is not left without ventilation when it’s busy.
How long does it take to clean an air handling unit?
Cleaning takes anything from half a day for one small unit to several shifts for a plant room full of them. Bigger units can be phased, and you can give us a ring on 0345 646 2711 or email us to plan it.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, normally ready within one working day.
What if parts of the system cannot be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.

Leave it or put it right?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. In a small place like Denton, a system that fails can take a site out of use.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.

Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Make sure the unit’s access doors open easily
- Stick to the filter change plan
- Diary the inspection date recommended in the report
- Look at the condensate drain whenever the unit is serviced
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
