AHU cleaning in Wintershill, done properly
Our AHU cleans for sites in Wintershill cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. The work covers heating and cooling coils, dampers and louvres and internal panels, and the jobs we see most are dust-coated heating and cooling coils and dirty filters cutting the airflow.
In a village or hamlet like Wintershill, few buildings have mechanical ventilation, 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. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, call 0345 646 2711, or send details by email with the site type, opening hours and a few pictures.
What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes from a few hours for a compact unit to a day or more for a large one. The timing of a visit to Wintershill is set by you, and the travel is our side of the planning.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Mention any parking or loading restrictions
- Clear loose items from the work area
Ask for a quote
The quickest way to a quote is to send photos: 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.

Between visits
Results last longer with the right care. Here’s what we suggest:
- Keep inspection doors on the unit in good order
- Book the next check in line with the report
- Make sure condensate is draining away
- Stick to the filter change plan
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
When to call us in Wintershill
Whatever surrounds a building in Wintershill, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.
Keep an eye out for these warning signs:
- Coils clogged with dust and debris
- Leaves and litter drawn into the unit
- Air handling units due a clean after building work
- Blocked condensate drains and slimy trays
For schools like Wyvern Technology College, the holidays are the usual time to inspect and clean ventilation.
What your quote should include
- Whether a written report and pictures are included
- Which accreditations they hold, and whether you can check them
- What hours they’ll be on site
- Whether the quote is based on a survey or photos
Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
