About our AHU cleaning in Sunningwell
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, so you know where you stand. If you are dealing with odours coming through the supply air and condensate trays that won’t empty, we can put it right, from dampers and louvres, internal panels and filter sections onwards.
Work in a small place like Sunningwell starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
A written report with pictures follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Your questions about AHU cleaning in Sunningwell
Can you come to Sunningwell after we close?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Sunningwell needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Do you cover smaller places like Sunningwell?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Are you fully insured?
Yes. We are fully insured, and we can share the details when you need them.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Can you quote from pictures?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will usually reply within one working day.
How it works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. We agree a date with you, plan the drive to Sunningwell and turn up when the site is quiet.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Let us know about permits to work or site inductions
- Clear loose items from the work area
- Let us know about parking and loading
Ask for a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or use the quote form.

Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Store the TR19 paperwork where auditors can find it
- Make sure the unit’s access doors open easily
- Plan the next inspection before the last report gets filed away
- Report musty smells from the vents right away
We recommend when the unit should next be inspected or cleaned, 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.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
How we price AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- The times the site is available
- The size of the system
- How easy every part is to reach
- Site requirements such as sign-in and permits
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, ring 0345 646 2711, or email photos for straight advice and a fixed quote.
Helping us quote
We can often survey from photos. Try to include:
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The site address and the type of premises
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. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
In-house cleaning or a specialist?
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
What we’re called out for in Sunningwell
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
It’s time to book a visit if you see:
- Plant that has been serviced but not cleaned
- Units needing a clean before a new tenant or handover
- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
School buildings such as Sunningwell Church of England Primary School are normally done in the holidays, so classrooms are not disturbed.

What AHU cleaning can’t fix
Not every problem is solved by AHU cleaning, and we will tell you before any work starts. It doesn’t solve:
- Problems with the unit’s controls or sensors
- Coils that are corroded or leaking and need replacing
- Dirty ducts beyond the unit itself
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think.
What the work covers

What the work involves, part by part
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
