AHU Cleaning in North Stoke
Our technicians work in North Stoke on AHU cleaning. Fixed quotes, work around your opening hours and photo reports on every job.
- Fan sections that haven’t been cleaned in years
- Dust-coated heating and cooling coils
- Plant that needs cleaning after a refit
For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Work can be phased by floor, building or site to keep disruption down.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
AHU cleaning in North Stoke, done properly
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with pictures, so you can see the unit’s condition for yourself. If you’re dealing with dust built up on fan impellers and debris and leaves in the fresh air intake, we can put it right, from dampers and louvres, heating and cooling coils and drain trays onwards.
Work in a small place like North Stoke starts with agreeing access and timings.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

FAQs for North Stoke
Will you come out to North Stoke?
Yes, we work in villages as well as towns, and North Stoke is covered. Photos of the system and directions to the site help us plan the visit.
Can you work in North Stoke outside opening hours?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in North Stoke needn’t be disturbed. When you phone us on 0345 646 2711, or send details by email, mention when the site is quiet.
Will we get paperwork for the AHU clean?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What happens if you can’t reach some of it?
Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
Do you have insurance?
Yes. We’re fully insured, and we can share the details when you need them.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it does not spread.
What do you do to protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
Different parts, different methods
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
What happens if it’s left?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. A planned visit to North Stoke is easier to arrange than an emergency callout.

What your team can do, and what needs us
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
What a clean will not put right
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Controls and BMS settings that run the unit
- Breakdowns that need a mechanical engineer
- The supply and extract ducts, quoted separately
If you’re not sure, just call 0345 646 2711, or email photos and we’ll give you a straight answer before you book.
Parts of the system we cover
- Filter sections
- Dampers and louvres
- Drain trays
- Heating and cooling coils
- Supply and extract fans
- Internal panels
How the visit works
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Seeing the system in photos first means the trip to North Stoke can be planned properly.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Tell us about site rules, permits or sign-in
- Dig out any earlier paperwork for the system
- Arrange a key holder or contact on site
Getting a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
