Essex · Air handling unit cleaning
Ashingdon AHU cleaning
One call covers cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Ashingdon, from survey to sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Drain trays holding standing water
- Air handling units with blocked filters
- Dust-coated heating and cooling coils
How it works
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes one overnight shift for many single units, with bigger plant phased, and the area is cleaned down before we leave. For a place like Ashingdon, we load the van from the survey notes so the work can be done in one visit where possible.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- 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
- Tell us about site rules, permits or sign-in
- Arrange a key holder or contact on site
- Let us know how we reach the system, including roofs, risers and plant rooms
Getting a quote
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, call us on 0345 646 2711 or email us.
Advice
How we handle AHU cleaning in Ashingdon
Our AHU cleans for sites in Ashingdon cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers filter sections, internal panels and drain trays, and people most often call us about plant that has been serviced but not cleaned and plant that needs cleaning after a refit.
Visits to a place like Ashingdon are fitted around opening hours. The method doesn’t change: inspect first, clean, then record what was done.
The report is your system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

How the job changes from site to site
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
Leave it or put it right?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. Around Ashingdon, a kitchen or building out of action is missed straight away.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.
What you get with us
- Ventilation hygiene specialists since 2009

Staff cleaning versus specialist work
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Fixed quotes for AHU cleaning in Ashingdon
The diagnosis comes before the price. The main factors are:
- The condition of the system
- Working hours and out-of-hours timing
- Any permits to work or inductions
- The number of sites or systems
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before we start.
What to send for a quote
There’s no need for technical detail. It helps if you can send:
- Your opening hours and when the area is out of use
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Detail shots of panels, filters and grilles
To get a fixed quote, give us a ring on 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We usually come back within one working day.
What a clean won’t put right
Not every problem is solved by AHU cleaning, and we will tell you before we start. It will not put right:
- The supply and extract ducts, quoted separately
- Controls and BMS settings that run the unit
- Airflow problems caused by the system’s design
Not sure which it is? You can phone us on 0345 646 2711 or email us and we will tell you honestly before you book.

Your questions about AHU cleaning in Ashingdon
Do you cover smaller places like Ashingdon?
Yes. Ashingdon is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can ventilation in schools around Ashingdon be cleaned out of term?
Yes, holiday work suits schools best. The FSA’s register shows about 9 schools and colleges with food registrations within roughly a mile and a half of Ashingdon. Send us your term dates when you call us on 0345 646 2711 or send us an email, and we will fit the work in.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Every site has its own report.
How long does it take to clean an air handling unit?
Typically the clean takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, out of hours if needed.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
