How we handle AHU cleaning in Waterhales
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you’re dealing with stale or musty smells from the ventilation and air handling units due a clean after building work, we can help, from drain trays, dampers and louvres and heating and cooling coils onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Each visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

When to call us in Waterhales
No filter stops everything. 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:
- Dust built up on fan impellers
- Intake sections clogged with outdoor debris
- Filters that are clogged or overdue
- Drain trays holding standing water
For schools like Drapers' Academy, the holidays are the usual time to inspect and clean ventilation.

What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- A single visit or a regular plan
- The times the site is available
- The number of sites or systems
- The size of the system
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
Asking for a quote
To help us quote quickly, please include:
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- When the site is open and when it’s quiet
- Wide photos of the system and the area around it
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.
When something else is needed
It’s worth knowing the limits before booking:
- Coils that are corroded or leaking and need replacing
- Faulty motors, drives or bearings
- Controls and BMS settings that run the unit
Not sure which it is? You can give us a ring on 0345 646 2711 or email us and we will tell you honestly before booking.

Why act early in Waterhales
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. That makes the next inspection of a building in Waterhales simpler. Equipment tucked in a roof space or outbuilding near Waterhales rarely gets looked at unless someone books it.
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before we start.
What you get with us
- Survey first, then a fixed quote
- CHAS, SafeContractor and ISO 9001

What the work involves, part by part
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.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Keeping the system healthy
Results last longer with the right care. We suggest:
- Plan the next inspection before the last report gets filed away
- Do not store bins or materials near the intake
- Look at the condensate drain whenever the unit is serviced
- Report stiff or damaged access doors
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
