AHU Cleaning in Ashington
AHU cleaning in Ashington from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Drain trays holding standing water
- Intake sections clogged with outdoor debris
- Fan sections that haven’t been cleaned in years
Why deal with it now?
Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Rural sites can’t always move to another kitchen or room when something fails.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Why choose Duct Doctor in Ashington

About our AHU cleaning in Ashington
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. Common call-outs are for filters that are clogged or overdue and air handling units never cleaned inside, on heating and cooling coils, internal panels and drain trays.
For a building in or near Ashington, access is agreed in advance and the visit is planned around the journey.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What else we do in Ashington
What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
How the visit works
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and leave you the report. On site, the work takes from a few hours for a compact unit to a day or more for a large one. For a village or hamlet like Ashington, tell us about narrow lanes, gates and parking when you book.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Arrange a key holder or contact on site
- Find the previous report, if there is one
- Tell us the best time to work, such as after service or at a weekend

Fixed quotes for AHU cleaning in Ashington
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Any permits to work or inductions
- Working hours and out-of-hours timing
- A single visit or a regular plan
- What state the system is in
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before work begins.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The times we could work without disrupting the site
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
How the job changes from site to site
Drain trays
Drain trays can rust and leak over time. We record their condition with photos so repairs can be planned.
