Oxfordshire · Air handling unit cleaning
Air handling unit cleaning in North Oxford, Oxfordshire
For cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in North Oxford, one call is all it takes: survey, fixed quote, work and sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Fan sections that haven’t been cleaned in years
- Units needing a clean before a new tenant or handover
- Dust-coated heating and cooling coils
Aftercare tips
Results last longer with the right care. We suggest:
- Keep filter changes on time and recorded
- Keep the area around the fresh air intake clear
- Make sure condensate is draining away
- Note any water around the unit or leaks below it
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
AHU cleaning in North Oxford
If the units serving a building in North Oxford have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Typical jobs include plant that needs cleaning after a refit and plant that has been serviced but not cleaned, across drain trays, internal panels and filter sections.
For a building near North Oxford, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

North Oxford: your questions answered
Do you work overnight in North Oxford?
Yes, out-of-hours work is a big part of what we do. That way a site in North Oxford doesn’t have to lose a day’s trading. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
Do you work in villages like North Oxford?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
What’s included in an AHU clean?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
What about areas you can’t get to?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
How long does it take to clean an air handling unit?
As a guide, it takes a single shift for a typical unit, longer for large or heavily soiled ones. We plan the shutdown around that, including evenings or weekends.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.

What affects the cost of AHU cleaning
You’ll get a fixed price before any work starts. It’s based on:
- When the work can happen, such as evenings, overnight or weekends
- One-off work versus a regular cycle
- What state the system is in
- The number of sites or systems
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
Asking for a quote
What to send for a quote:
- When the site is open and when it’s quiet
- Any previous report or certificate
- The site address and the type of premises
- Detail shots of panels, filters and grilles
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before any work starts.
How the visit works
Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, clear away and hand over the paperwork. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Visits to a place like North Oxford are planned ahead, so we arrive with what the survey says the job needs.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Name a contact who can let us in at the agreed time
- Have your last certificate or report to hand
- Tell us the best time to work, such as after service or at a weekend

Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. Around North Oxford, a kitchen or building out of action is missed straight away.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, call 0345 646 2711 or send us an email for straight advice and a fixed quote.

Staff cleaning versus specialist work
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, it’s best reported rather than tackled in-house. We can diagnose it and quote.
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, alongside our reports.
Managing agents and facilities teams in North Oxford
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.
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
