AHU cleaning in Woodham Walter, done properly
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers internal panels, drain trays and heating and cooling coils, and people most often call us about intake sections clogged with outdoor debris and odours coming through the supply air.
Work in a small place like Woodham Walter starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The paperwork matters as much as the work. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Part by part
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before we start, and the area around the work is covered and protected. The work itself takes one overnight shift for many single units, with bigger plant phased. Photos of the system and how to reach it help us plan a visit to Woodham Walter.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about permits to work or site inductions
How to get a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, call 0345 646 2711 or drop us a line.
Advice
In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
What affects the cost of AHU cleaning
We quote each job individually. This is what makes a difference:
- How many systems or sites are involved
- Where the site is and how we reach it
- The scale of the work
- How easy every part is to reach
What you pay depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.
Asking for a quote
What to send for a quote:
- Problems your staff have spotted
- The paperwork from the last visit, if you have it
- A few general shots of the system
- Your opening hours and when the area is out of use
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
