Saffron Walden AHU cleaning
One call covers air handling unit cleaning in Saffron Walden, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Dirty fans and fan housings

Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too across Essex. Larger estates can be phased building by building around the people who use them.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
How we handle AHU cleaning in Saffron Walden
Our AHU cleans for sites in Saffron Walden cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers filter sections, drain trays and supply and extract fans, and common reasons people get in touch are filters that are clogged or overdue and fan sections that haven’t been cleaned in years.
Buildings in towns like Saffron Walden often have ventilation added in stages, with units on the roof or in a plant room. An inspection shows which parts need cleaning, so you are not paying for more than the system needs.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Common problems we fix in Saffron Walden
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Saffron Walden, that’s air they breathe for hours at a time.
It’s time to book a visit if you see:
- Dirty fans and fan housings
- Condensate trays that won’t empty
- Air handling units never cleaned inside
- Odours coming through the supply air
Wherever a school like R A Butler Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What your quote should include
- Proof of accreditation you can verify
- Whether inaccessible sections are listed on the report
- Whether a written report and pictures are included
- Whether the quote shows VAT
Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Keep the area around the fresh air intake clear
- Keep filter changes on time and recorded
- Keep the certificate and photo report with the plant records
- Look at the condensate drain whenever the unit is serviced
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Part by part
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.

Busy, occupied buildings like these are where clean supply air matters most. Saffron Walden Community Hospital is the nearest hospital, about 0.6 miles east of Saffron Walden.

The nearest railway station is Audley End station, roughly 2 miles south-west of the centre.

What staff can safely do
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Your questions about AHU cleaning in Saffron Walden
Is AHU cleaning available in Saffron Walden?
Yes. We work across London and the South East, and Saffron Walden is part of that. Get in touch with the details and we will arrange a survey.
Do you do school ventilation cleaning in Saffron Walden in the summer holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 13 schools and colleges with food registrations within roughly a mile and a half of Saffron Walden. Just phone us on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, give us a ring on 0345 646 2711 or send us an email with the site type, opening hours and a few pictures.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
What we do, step by step
We are 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. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. We arrive in Saffron Walden once you’ve closed and leave the site ready for the morning.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Tell us where we can park and unload
- Arrange a key holder or contact on site
- Let us know when the site is closed or quiet
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, ring 0345 646 2711, or send details by email.

Why it’s worth doing now in Saffron Walden
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. A small fault found now is a quick job; the same fault found later can close the site.
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.
