AHU cleaning in Spelsbury, done properly
Our AHU cleans for sites in Spelsbury cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. The work covers internal panels, supply and extract fans and drain trays, and people most often call us about dust-coated heating and cooling coils and condensate trays that won’t empty.
For a building in or near Spelsbury, access is agreed in advance and the visit is planned around the journey.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

When to call us in Spelsbury
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
The symptoms we’re asked about most include:
- Plant that has been serviced but not cleaned
- Dirty coils holding back the airflow
- Units needing a clean before a new tenant or handover
- Rooms that smell stuffy when the system runs
Wherever a school like Chadlington Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

For landlords and multi-site operators
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.

How the visit works
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, which takes from a few hours for a compact unit to a day or more for a large one. The timing of a visit to Spelsbury is set by you, and the travel is our side of the planning.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Before we arrive
- Mention any parking or loading restrictions
- Find the previous report, if there is one
- Let us know how we reach the system, including roofs, risers and plant rooms

Advice
How the job changes from site to site
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
FAQs for Spelsbury
Can ventilation in schools around Spelsbury be cleaned out of term?
Yes. The holidays are the usual time for school work. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Spelsbury, it pays to plan holiday dates ahead. Just give us a ring on 0345 646 2711 or drop us a line with your term dates and we’ll plan around them.
Can you get to a site in Spelsbury?
Yes. Villages and rural sites across the South East are part of our work, Spelsbury included. Photos of the system and directions to the site help us plan the visit.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we are fully insured.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Are you insured?
Yes. We’re fully insured, and the details are available on request.
Do you work evenings or weekends?
Yes. We time the work to fit the building’s hours. Healthcare and care settings are planned with staff.
When it’s something else
AHU cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- Leaking heating or cooling coils
- Mechanical faults with motors, belts or bearings
- The supply and extract ducts, quoted separately
Not sure which it is? You can call 0345 646 2711, or send details by email and we’ll tell you honestly.
Parts of the system we cover
- Internal panels
- Drain trays
- Dampers and louvres
- Heating and cooling coils
- Filter sections
- Supply and extract fans

Fixed quotes for AHU cleaning in Spelsbury
A fixed price needs a few facts first. We check:
- Parking and loading at the site
- The scale of the work
- The times the site is available
- The condition of the system
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.
Helping us quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- Where the site is and what kind of site it is
- Problems your staff have spotted
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before we start.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- File each AHU report in the maintenance log
- Plan the next inspection before the last report gets filed away
- Keep filter changes on time and recorded
- Report water on the plant room floor
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
