Common questions in Hildenborough
Can you work in Hildenborough outside opening hours?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Hildenborough needn’t be disturbed. Just call 0345 646 2711 or send us an email with your opening times and we will plan around them.
Is Hildenborough within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Hildenborough included. Photos of the system and directions to the site help us plan the visit.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we will quote them together.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What do you clean inside the unit?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
What happens if you can’t reach some of it?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
How long will the unit be out of action?
Typically the clean takes a single shift for a typical unit, longer for large or heavily soiled ones. The shutdown is planned to fit, out of hours if needed.
How we handle AHU cleaning in Hildenborough
Our AHU cleans for sites in Hildenborough cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. Typical jobs include air handling units with blocked filters and blocked condensate drains and slimy trays, on heating and cooling coils, filter sections and supply and extract fans.
Somewhere as small as Hildenborough, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
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.

Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Hildenborough, about 24 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible. For Hildenborough, the closest hospital is Tonbridge Cottage Hospital, roughly 3 miles south-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Healthcare ventilation, from large hospitals like Tonbridge Cottage Hospital (about 3 miles south-east) to small clinics, depends on clean filters, coils and ducts. For workplaces around Hildenborough station with mechanical ventilation, cleaning can be done in the evening or at weekends. School buildings such as Hildenborough Church of England Primary School are typically done in the holidays, so classrooms aren’t disturbed.

Hildenborough’s nearest station is Hildenborough station, roughly 0.7 miles west of the centre.

Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Keep the certificate and photo report with the plant records
- Make sure the unit’s access doors open easily
- Keep the area around the fresh air intake clear
- Flag stale or damp smells in the supply air
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Systems in rural buildings are often out of sight and out of mind.

Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
What the work involves, part by part
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
How we price AHU cleaning
A fixed price needs a few facts first. We check:
- How easy every part is to reach
- A single visit or a regular plan
- What state the system is in
- How big the system is
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.
Helping us quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
To get a fixed quote, give us a ring on 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You’ll typically have a quote within one working day.
