How we handle AHU cleaning in Whitemans Green
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. If you have dust built up on fan impellers and rooms that smell stuffy when the system runs, we can help, from filter sections, dampers and louvres and heating and cooling coils onwards.
Somewhere as small as Whitemans Green, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Duct Doctor has been trading since 2009, as 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.

How the visit works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Somewhere like Whitemans Green, lanes, gates and parking are worth mentioning in advance.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Arrange a key holder or contact on site
- Agree a time when the area can be out of use
- Mention any locked doors, roof access or ceiling voids
How to get a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
When it’s something else
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Ductwork downstream of the unit, which is a separate clean
- Controls and BMS settings that run the unit
- Faulty motors, drives or bearings
Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we will tell you honestly.
Parts of the system we cover
- Filter sections
- Supply and extract fans
- Heating and cooling coils
- Drain trays
- Internal panels
- Dampers and louvres
Looking after it afterwards
So the system stays in good health:
- Make sure the unit’s access doors open easily
- Report water on the plant room floor
- Store the TR19 paperwork where auditors can find it
- Keep filter changes on time and recorded
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Do you need AHU cleaning in Whitemans Green?
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Most sites get in touch when they notice one of these:
- Air handling units never cleaned inside
- Fan sections that haven’t been cleaned in years
- Air handling units due a clean after building work
- Dirty filters cutting the airflow
For schools like Holy Trinity Church of England Primary School, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before booking
- Whether VAT is included
- Whether they recommend a next date
- Whether the work can be done while the site is closed
- What happens if part of the system can’t be accessed

FAQs for Whitemans Green
Can you get to a site in Whitemans Green?
Yes. Villages and rural sites across the South East are part of our work, Whitemans Green included. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you work in Whitemans Green outside opening hours?
Yes, evening, overnight and weekend work is normal for us. That way a site in Whitemans Green doesn’t have to lose a day’s trading. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
How long will the unit be out of action?
As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. The shutdown is planned to fit, including evenings or weekends.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.
How much does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before any work starts.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.
Can you price the work without visiting?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. If pictures are not enough, we’ll survey first.
Why it’s worth doing now in Whitemans Green
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Rural sites cannot always move to another kitchen or room when something fails.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, call 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.

Different parts, different methods
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so you can decide on any repairs.
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 the housing around them is cleaned too.
