How the visit works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and leave you the report. The visit itself takes one overnight shift for many single units, with bigger plant phased. We plan the journey to Bloxham and bring what the job is likely to need.
- 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.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Clear the space around the work
- Name a contact who can let us in at the agreed time

AHU cleaning for kitchens and businesses in Bloxham
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. The work covers supply and extract fans, heating and cooling coils and filter sections, and the jobs we see most are units needing a clean before a new tenant or handover and leaves and litter drawn into the unit.
In a place like Bloxham, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
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 are fully insured.

What we’re called out for in Bloxham
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Signs it’s time to call us include:
- Plant that has been serviced but not cleaned
- Debris and leaves in the fresh air intake
- Condensate trays that won’t empty
- Rooms that smell stuffy when the system runs
If you manage a school such as Bloxham Church of England Primary School, ventilation cleaning is best booked for the holidays.

Bloxham questions
Can you work in Bloxham outside opening hours?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.
Can you get to a site in Bloxham?
Yes. Villages and rural sites across the South East are part of our work, Bloxham included. Just mention lanes, gates or anything else about the site when you book.
What happens if you can’t reach some of it?
We record them on the report, with photos where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.
What do you clean inside the unit?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Is there a report after cleaning?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can quote for both.
Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Note any water around the unit or leaks below it
- Do not ignore odours coming through the grilles
- Make sure condensate is draining away
- Change filters on schedule and log each change
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
For landlords and multi-site operators
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours and out-of-hours timing
- Any permits to work or inductions
- The condition we find in the survey
- The size of the system
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Your opening hours and when the area is out of use
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
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. Add the site type and your opening hours, and we can price many jobs without a visit.
How the job changes from site to site
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
