Ashford questions
Do you clean school ventilation in Ashford in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 15 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Ashford. Just call 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Can you do AHU cleaning in Ashford?
Yes, Ashford is within the area we cover across London and the South East. Get in touch with the details and we’ll arrange a survey.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What should I send you?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
AHU cleaning for kitchens and businesses in Ashford
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. We’re often asked to deal with leaves and litter drawn into the unit and plant that has been serviced but not cleaned, on heating and cooling coils, supply and extract fans and drain trays.
Larger buildings in Ashford can have several air handling units serving different floors. Each has filters, coils, a drain tray and a fan that need attention, and a drain tray holding water is something we look for on every unit.
The paperwork matters as much as the work. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.
In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Ashford buildings and their air
Food Standards Agency data includes about 15 schools, colleges and universities and about 24 hospitals, care homes and childcare premises within 1.5 miles or so of the middle of Ashford. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Ashford, about 48 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours. For Ashford, the closest hospital is William Harvey Hospital, roughly 2.1 miles east. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
If you manage a school such as Chilmington Green Primary School, ventilation cleaning is best booked for the holidays. Healthcare ventilation, from large hospitals like William Harvey Hospital (about 2.1 miles east) to small clinics, depends on clean filters, coils and ducts.

How the visit works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. We’ll ask where we can park in Ashford and how to get equipment to the system, as those shape the visit.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Tell us where we can park and unload
- Find the previous report, if there is one
- Clear loose items from the work area
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.

Honest limits
To be straight with you, there are a few things this work won’t fix:
- Ductwork downstream of the unit, which is a separate clean
- Problems with the unit’s controls or sensors
- Ventilation that was badly designed in the first place
If in doubt, give us a ring on 0345 646 2711 or send us an email and we will say what we think.
What we work on in Ashford
- Dampers and louvres
- Heating and cooling coils
- Internal panels
- Supply and extract fans
- Filter sections
- Drain trays
Why deal with it now?
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Records matter in Ashford: insurers and inspectors may ask to see them.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.
Why choose Duct Doctor in Ashford
- Full insurance on every job
- Each visit written up, with photos
- Fixed quotes, typically within one working day
- Trading since 2009
Between visits
To keep the system working properly between visits:
- Clear leaves and litter away from the intake
- Book the next check in line with the report
- Report musty smells from the vents straight away
- File each AHU report in the maintenance log
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
What the work involves, part by part
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. The impeller, its housing and the fan chamber are cleaned.
When to call us in Ashford
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Common reasons sites call us include:
- Dust built up on fan impellers
- Debris and leaves in the fresh air intake
- Filters that are clogged or overdue
- Plant that has been serviced but not cleaned
If you run an office near Ashford International station, its supply ductwork can gather dust for years before anyone looks inside.
