How we handle AHU cleaning in Bolney
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and give you a fixed quote, so you know where you stand. If you’re dealing with air handling units with blocked filters and drain trays holding standing water, we can help.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Bolney buildings and their air
The nearest hospital to Bolney is The Dene Hospital, about 2.6 miles south-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. About 35 miles out from central London, Bolney is part of the South East area we work across. Visits are booked around your hours, evenings and weekends included.
Healthcare ventilation, from large hospitals like The Dene Hospital (about 2.6 miles south-east) to small clinics, depends on clean filters, coils and ducts.

What’s near Bolney
For rail, the closest station is Wivelsfield station, about 4.1 miles south-east of the centre. Nearby you will also find The Dene Hospital (2.6 miles south-east) and Cuckfield Museum (2.6 miles east). For a walk, there’s Blunts Wood and Paiges Meadow.
Staff cleaning versus specialist work
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 they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.

How the visit works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Visits to a village like Bolney are booked in advance, at a time that suits whoever runs the site.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Before we arrive
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool
- Tell us the best time to work, such as after service or at a weekend
How to get a quote
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.
Advice
Managing agents and facilities teams in Bolney
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Why act early in Bolney
Stuffy rooms and stale smells in a building in Bolney can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. It’s simpler to plan the work at Bolney now than to arrange it in a hurry later.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.

Common questions in Bolney
Will you come out to Bolney?
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 offer AHU cleaning in Bolney?
Yes, we work in Bolney and the places around it. Get in touch with the details and we’ll arrange a survey.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
What happens if you cannot reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Do you work with multi-site operators?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Signs you need AHU cleaning in Bolney
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that’s where slime and odours start.
Signs it’s time to call us include:
- Dust-coated heating and cooling coils
- Dirty filters cutting the airflow
- Dust built up on fan impellers
- Intake sections clogged with outdoor debris
Wherever a school like Bolney CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Questions to ask before booking
- When the next visit should be, and why
- When they can work, and whether that’s outside your opening hours
- What insurance they carry
- Whether the figure could change on the day
Between visits
Results last longer with the right care. We suggest:
- Make sure condensate is draining away
- Keep the certificate and photo report with the plant records
- Keep the area around the fresh air intake clear
- Book the next check in line with the report
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
How the job changes from site to site
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
