How the job changes from site to site
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey so the quote reflects it.
AHU cleaning for kitchens and businesses in Upper Harbledown
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. The work covers drain trays, filter sections and internal panels, and the jobs we see most are units needing a clean before a new tenant or handover and condensate trays that won’t empty.
Work in a small place like Upper Harbledown starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Keep filter changes on time and recorded
- Note any water around the unit or leaks below it
- Keep the certificate and photo report with the plant records
- Report musty smells from the vents straight away
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.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.

FAQs for Upper Harbledown
Do you work in villages like Upper Harbledown?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Do you clean school ventilation in Upper Harbledown in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 11 schools and colleges with food registrations within roughly a mile and a half of Upper Harbledown. You can give us a ring on 0345 646 2711, or send details by email with the dates the site is empty.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.

What affects the quote in Upper Harbledown
The quote reflects the site in front of us. We consider:
- The condition of the system
- How many systems or sites are involved
- The scale of the work
- Access, including roofs, risers and ceiling voids
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Photos are the quickest way to a quote: 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.
What your team can do, and what needs us
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
For ventilation and air handling systems, in-house care is mostly about checks: 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 are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Upper Harbledown before we set off.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
How to prepare
- Mention any sign-in, permit or induction we need
- Let us know how we reach the system, including roofs, risers and plant rooms
- Arrange a key holder or contact on site
