- Dust-coated heating and cooling coils
- Units that have only ever had filter changes
- Rooms that smell stuffy when the system runs
What we are called out for in Thruxton
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
These are the problems we see most often:
- Air handling units never cleaned inside
- Dust-coated heating and cooling coils
- Drain trays holding standing water
- Rooms that smell stuffy when the system runs
School buildings such as Amport Church of England Primary School are normally done in the holidays, so classrooms aren’t disturbed.

How we handle AHU cleaning in Thruxton
Where a building in Thruxton has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. The work covers internal panels, heating and cooling coils and supply and extract fans, and people most often call us about dirty coils holding back the airflow and dirty filters cutting the airflow.
Somewhere as small as Thruxton, ducted ventilation is normally 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, 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.

Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Store the TR19 paperwork where auditors can find it
- Stick to the filter change plan
- Report musty smells from the vents right away
- Report water on the plant room floor
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.

What we do, step by step
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes one overnight shift for many single units, with bigger plant phased. Somewhere as small as Thruxton, the date and timings are agreed with you well before the day.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Clear loose items from the work area
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

What AHU cleaning looks like in Thruxton
Food Standards Agency records list about 3 care, childcare and hospital premises registered as food businesses in and around Thruxton, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. The nearest hospital to Thruxton is Andover War Memorial Hospital, about 3.9 miles 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 Andover War Memorial Hospital (about 3.9 miles east) to small clinics, depends on clean filters, coils and ducts.

Nearby you will also find Andover War Memorial Hospital (3.9 miles east) and Ludgershall Castle (3.8 miles north-west). Not far away are Anton Lakes and Quarley Hill.
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.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
What affects the quote in Thruxton
The quote reflects the site in front of us. We take into account:
- How big the system is
- The times the site is available
- Travel, parking and unloading
- Site requirements such as sign-in and permits
The cost depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
- A few general shots of the system
- Problems your staff have spotted
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To get going, call us on 0345 646 2711 or use the quote form.
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Thruxton: your questions answered
Do you work at weekends in Thruxton?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Thruxton needn’t be disturbed. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
Can you do AHU cleaning in Thruxton?
Yes. Our area runs across London and the South East, Thruxton included. You can give us a ring on 0345 646 2711 or send us an email and let us know what needs doing.
What about areas you can’t get to?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after pictures. They’re worth keeping with the plant records.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with pictures where it helps.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. At the end, the area is cleaned down.
Why it’s worth doing now in Thruxton
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Somewhere as small as Thruxton, losing a kitchen or building to a fault is felt by everyone who uses it.
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before work begins.
