Questions from Foulford
Can you come to Foulford after we close?
Yes, nights and weekends are routine for us. That way a site in Foulford doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Do you clean school ventilation in Foulford in the holidays?
Yes, and it’s the easiest time to do it. Around Foulford, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Do you have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
What should I send you?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Do you repair air handling units?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We will flag anything we notice during the clean.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
What do you clean inside the unit?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
About our AHU cleaning in Foulford
Our AHU cleans for sites in Foulford cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. Common call-outs are for fan sections that haven’t been cleaned in years and rooms that smell stuffy when the system runs, across internal panels, supply and extract fans and dampers and louvres.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What AHU cleaning can’t fix
Not every problem is solved by AHU cleaning, and we will tell you before we start. It will not 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 call 0345 646 2711 or send us an email and we’ll tell you honestly before you book.

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
In-house cleaning or a specialist?
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, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
What happens on the day
We work around your opening hours, not the other way round. 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 half a day to a full day per unit, with large plant planned over several shifts. In a small place like Foulford, the journey is planned ahead and the visit arranged around the site’s hours.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us where we can park and unload

Signs you need AHU cleaning in Foulford
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
If you notice any of these, it’s worth a diagnosis:
- Filters that are clogged or overdue
- Condensate trays that will not empty
- Debris and leaves in the fresh air intake
- Rooms that smell stuffy when the system runs
Classrooms and halls at schools such as Ringwood School Academy are easiest to work in when pupils are away.
Questions to ask before booking
- Whether inaccessible sections are listed on the report
- If the quote is a fixed price or an estimate
- What insurance they carry
- Whether the whole system is included, or only the parts that are easy to reach

How the job changes from site to site
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
What affects the quote in Foulford
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether it’s a one-off visit or part of a schedule
- Whether several sites go on one quote
- The condition of the system
- Where the site is and how we reach it
What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before any work starts.
Asking for a quote
You don’t need the technical terms. Just send:
- The paperwork from the last visit, if you have it
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
