About our AHU cleaning in Finkley
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from pictures or on site, followed by a fixed quote before any cleaning starts. We’re often asked to deal with dust-coated heating and cooling coils and rooms that smell stuffy when the system runs, on drain trays, supply and extract fans and filter sections.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

How we price AHU cleaning
The quote reflects the site in front of us. We take into account:
- Whether we need access equipment or extra panels
- Any permits to work or inductions
- Working hours and out-of-hours timing
- The condition we find in the survey
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, call 0345 646 2711 or email us and we’ll give you an honest view and a fixed quote.
Asking for a quote
When you contact us, it’s useful to have:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Part by part
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey so the quote reflects it.
Finkley: your questions answered
Can you do AHU cleaning in Finkley?
Yes, we work in Finkley and the places around it. You can give us a ring on 0345 646 2711 or use the quote form and let us know what needs doing.
Can the work in Finkley be done at night or at weekends?
Yes, nights and weekends are routine for us. The site is handed back ready to open. When you call 0345 646 2711, or email photos, mention when the site is quiet.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
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.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we will suggest an interval after the first clean.
Looking after it afterwards
To keep the system working properly between visits:
- Make sure condensate is draining away
- Watch for drips or damp patches near the plant
- Stick to the filter change plan
- Don’t store bins or materials near the intake
When we have closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
Why deal with it now?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Finkley simpler. Systems in rural buildings are often out of sight and out of mind.
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before any work starts.
Why us?
- Evenings, overnight and weekends, plus 24/7 emergency callout

What else we do in Finkley
What we do, step by step
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, and that takes a single shift for a typical unit, longer for large or heavily soiled ones. Rural roads and tight entrances are worth telling us about before a visit to Finkley.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Clear loose items from the work area
- Let us know when the site is closed or quiet
Get a fixed quote

Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Airflow problems caused by the system’s design
- Mechanical faults with motors, belts or bearings
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we will tell you honestly.
