How we handle AHU cleaning in Frilford Heath
Where a building in Frilford Heath has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. The work covers dampers and louvres, supply and extract fans and filter sections, and people most often call us about filters that are clogged or overdue and plant that has been serviced but not cleaned.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What AHU cleaning can’t fix
Not every problem is solved by AHU cleaning, and we’ll tell you before work begins. It won’t put right:
- Dirty ducts beyond the unit itself
- Controls and BMS settings that run the unit
- Leaking heating or cooling coils
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.
What the work covers
- Drain trays
- Heating and cooling coils
- Internal panels
- Dampers and louvres
- Filter sections
- Supply and extract fans
What staff can safely do
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
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 will take a look and give you a fixed quote.
Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Report water on the plant room floor
- Keep the certificate and photo report with the plant records
- Change filters on schedule and log each change
- Diary the inspection date recommended in the report
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
How the job changes from site to site
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so you can decide on any repairs.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey, before we quote.
What affects the cost of AHU cleaning
Every site gets its own quote. These are the things that affect it:
- Parking and loading at the site
- The condition of the system
- The size of the system
- Site rules, permits and inductions
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before we start.
Helping us quote
To speed up the quote, send us:
- Close-ups of filters, grilles, hatches or access panels
- Photos showing the whole system and its surroundings
- How we’d reach plant on a roof or in a plant room
- The paperwork from the last visit, if you have it
To get a fixed quote, phone us 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. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.
Common questions in Frilford Heath
Can you work in Frilford Heath outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Frilford Heath keeps running as normal. Let us know the hours you’re closed and we’ll book within them.
Is Frilford Heath within the area you cover?
Yes, we work in villages as well as towns, and Frilford Heath is covered. Photos of the system and directions to the site help us plan the visit.
What does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will normally reply within one working day.
Does the AHU have to be shut down for cleaning?
Yes, for the time we’re working on it. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
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.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.
What information do you need?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
What happens on the day
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes from a few hours for a compact unit to a day or more for a large one. Somewhere as small as Frilford Heath, the date and timings are agreed with you well before the day.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- 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 access, such as roof hatches, plant rooms, ceilings or locked areas
- Dig out any earlier paperwork for the system
- Name a contact who can let us in at the agreed time
