Part by part
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
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.
About our AHU cleaning in Cliffs End
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. If you have debris and leaves in the fresh air intake and air handling units with blocked filters, we can help.
In a village or hamlet like Cliffs End, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We’ve 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’re fully insured.

AHU cleaning in Cliffs End: local notes
Going by the FSA’s register, there are about 6 schools, colleges and universities and about 4 caring premises (care homes, nurseries and hospitals) serving food across Cliffs End and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 1.9 miles east of Cliffs End is Ramsgate General Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Wherever a school like Chilton Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. For workplaces around Thanet Parkway station with mechanical ventilation, cleaning can be done in the evening or at weekends. Healthcare ventilation, from large hospitals like Ramsgate General Hospital (about 1.9 miles east) to small clinics, depends on clean filters, coils and ducts.
Cliffs End is about 2 miles west of Ramsgate, in Kent. Across the CT12 area, we can carry out AHU cleaning at your premises. Across Kent, we cover 922 places, and Cliffs End is one of them. There’s also a page for Maidstone, about 37 miles away.

What a clean won’t put right
AHU cleaning cannot fix everything, and we’d rather say so up front. It does not solve:
- The supply and extract ducts, quoted separately
- Damaged coils beyond cleaning
- Mechanical faults with motors, belts or bearings
If in doubt, ring 0345 646 2711 or use the quote form and we will say what we think.
What the work covers
- Filter sections
- Supply and extract fans

Cliffs End questions
Can you get to a site in Cliffs End?
Yes. Villages and rural sites across the South East are part of our work, Cliffs End included. Let us know about access, parking and anything unusual about getting there when you book.
Do you clean school ventilation in Cliffs End in the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 6 schools, colleges and universities with registered kitchens within about a mile and a half of Cliffs End. Booking early in the term gives the best choice of holiday dates.
How long does it take to clean an air handling unit?
Cleaning takes half a day to a full day per unit, with large plant planned over several shifts. Large plant can be split over several shifts, and you can phone us on 0345 646 2711, or send details by email to plan it.
Can one contract cover all our sites?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
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 are fully insured.
Do you do ventilation duct cleaning too?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Do you work evenings or weekends?
Yes. We time the work to fit the building’s hours. In hospitals and care homes, we agree timings with the site team.
Between visits
Here’s the after-treatment advice, short and simple:
- File each AHU report in the maintenance log
- Book the next check in line with the report
- Make sure the unit’s access doors open easily
- Note any water around the unit or leaks below it
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
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.
What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. Somewhere as small as Cliffs End, losing a kitchen or building to a fault is felt by everyone who uses it.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

What else we do in Cliffs End
In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
What happens on the day
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes one overnight shift for many single units, with bigger plant phased. Seeing the system in photos first means the trip to Cliffs End can be planned properly.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
How to prepare
- Let us know about permits to work or site inductions
- Find the previous report, if there is one
- Agree a time when the area can be out of use
Ask for a quote
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
