How we handle AHU cleaning in Whitewood
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with pictures, so you can see the unit’s condition for yourself. Common call-outs are for drain trays holding standing water and dust-coated heating and cooling coils, across supply and extract fans, filter sections and internal panels.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Common problems we fix in Whitewood
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, a little more each month.
What we’re most often called out for:
- Air handling units due a clean after building work
- Intake sections clogged with outdoor debris
- Units that have only ever had filter changes
- Rooms that smell stuffy when the system runs
An inspection comes first for any ventilation job around Whitewood, so the cleaning matches what’s there.
What your quote should include
- Whether a written report and photos are included
- Which accreditations they hold, and whether you can check them
- Whether the price is fixed
- Whether inaccessible sections are listed on the report
What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Planning a trip to Whitewood ahead is easier for everyone than a rushed one.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before we start.

What affects the quote in Whitewood
Sites vary more than people expect. The main factors:
- How many systems or sites are involved
- Access, including roofs, risers and ceiling voids
- Working hours and out-of-hours timing
- The condition we find in the survey
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.
What to send for a quote
To speed up the quote, please include:
- The paperwork from the last visit, if you have it
- A few general shots of the system
- Problems your staff have spotted
- Any access panels or hatches you can see
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.

How the job changes from site to site
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.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
What we do, step by step
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. We agree a date with you, plan the drive to Whitewood and turn up when the site is quiet.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Name a contact who can let us in at the agreed time
- Move anything stored near the system

Aftercare tips
Here’s the after-treatment advice, in brief:
- Report musty smells from the vents straight away
- File each AHU report in the maintenance log
- Diary the inspection date recommended in the report
- Report water on the plant room floor
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
When it’s something else
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It doesn’t solve:
- Faulty motors, drives or bearings
- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils
If you’re not sure, just give us a ring on 0345 646 2711 or send us an email and we’ll give you a straight answer.
