About our AHU cleaning in Bedwell
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. The work covers heating and cooling coils, internal panels and drain trays, and common reasons people get in touch are dust-coated heating and cooling coils and filters that are clogged or overdue.
Around a place like Bedwell, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

How the visit works
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. For a site near Bedwell, the work is booked around your opening hours, evenings and weekends included.
- 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.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Preparing for the visit
- Let us know about parking and loading

What we are called out for in Bedwell
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Bedwell, that’s air they breathe for hours at a time.
If you notice any of these, it’s worth a diagnosis:
- Filters that are clogged or overdue
- Debris and leaves in the fresh air intake
- Air handling units never cleaned inside
- Odours coming through the supply air
Lister Hospital, about 1.7 miles north-west, is the nearest hospital to Bedwell, and healthcare sites of every size need their supply air kept clean.
What to look for in a quote
- What insurance they carry
- Whether a written report and pictures are included
- Which accreditations they hold, and whether you can check them
- What happens if part of the system can’t be accessed
Bedwell: your questions answered
Do you work in villages like Bedwell?
Yes, Bedwell is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Can the work in Bedwell be done at night or at weekends?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
What information do you need?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Bedwell simpler. Booking ahead lets us plan the trip to Bedwell at a time that suits you.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, call us on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.

Different parts, different methods
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
What your team can do, and what needs us
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Keep filter changes on time and recorded
- Make sure condensate is draining away
- Make sure the unit’s access doors open easily
- Do not ignore odours coming through the grilles
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
