How we handle AHU cleaning in Holmer Green
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers dampers and louvres, drain trays and internal panels, and the jobs we see most are air handling units never cleaned inside and air handling units due a clean after building work.
Smaller buildings around Holmer Green often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
How the job changes from site to site
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. A site near Holmer Green usually has room to park, so the questions are about access to the system and your hours.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Find the previous report, if there is one
- Move anything stored near the system

Advice
Why it’s worth doing now in Holmer Green
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. It’s better to plan the work at a site near Holmer Green than wait for a failure.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

Signs you need AHU cleaning in Holmer Green
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Any of these means the system needs a check-up:
- Air handling units with blocked filters
- Stale or musty smells from the ventilation
- Intake sections clogged with outdoor debris
- Units needing a clean before a new tenant or handover
For schools like Holmer Green Senior School, the holidays are the usual time to inspect and clean ventilation.
What your quote should include
- Whether a survey comes first
- When they can work, and whether that’s outside your opening hours
- Proof of insurance
- Exactly which parts of the system are covered
Fixed quotes for AHU cleaning in Holmer Green

- Where the site is and how we reach it
- Whether several sites go on one quote

Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Make sure the unit’s access doors open easily
- Don’t ignore odours coming through the grilles
- Stick to the filter change plan
- Note any water around the unit or leaks below it
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.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
