How the visit works
Each visit runs to the same pattern: sheeting and protection first, make the system safe, carry out the AHU cleaning, clear away and hand over the paperwork. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Seeing the system in photos first means the trip to Denton can be planned properly.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Preparing for the visit
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend
- Dig out any earlier paperwork for the system

About our AHU cleaning in Denton
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote before any cleaning starts. The work covers internal panels, dampers and louvres and heating and cooling coils, and common reasons people get in touch are condensate trays that won’t empty and units that have only ever had filter changes.
Work in a small place like Denton starts with agreeing access and timings.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Check the drain tray is emptying during routine visits
- Keep filter changes on time and recorded
- Report water on the plant room floor
- Book the next check in line with the report
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
When to call us in Denton
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Denton, that’s air they breathe for hours at a time.
Look out for any of the following:
- Dust built up on fan impellers
- Intake sections clogged with outdoor debris
- Rooms that smell stuffy when the system runs
- Filters that are clogged or overdue
Around Denton, as anywhere, ventilation cleaning begins with an inspection.

Different parts, different methods
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.

- Ductwork downstream of the unit, which is a separate clean
- Breakdowns that need a mechanical engineer
- Building management system faults

Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too across Kent. Work can be phased by floor, building or site to keep disruption down.
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. With shared responsibility, good records help everyone.
What staff can safely do
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. Leave those to us.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Your questions about AHU cleaning in Denton
Will you come out to Denton?
Yes. Denton is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Can you work in Denton outside opening hours?
Yes, we can come after you close and finish before you open. That way a site in Denton does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Can you price the work without visiting?
Normally, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote typically follows within one working day. Some sites still need a visit, and we’ll say so.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after photos. Keep them in the maintenance log.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What if parts of the system can’t be reached?
Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
