About our AHU cleaning in Swalcliffe
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. The work covers internal panels, drain trays and dampers and louvres, and people most often call us about filters that are clogged or overdue and dirty fans and fan housings.
Somewhere as small as Swalcliffe, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What AHU cleaning can’t fix
In fairness, there are a few things this work will not fix:
- Damaged coils beyond cleaning
- Breakdowns that need a mechanical engineer
- The supply and extract ducts, quoted separately
If in doubt, give us a ring on 0345 646 2711 or send us an email and we’ll say what we think.
What we work on in Swalcliffe
- Supply and extract fans
- Drain trays
- Filter sections
- Internal panels
- Heating and cooling coils
- Dampers and louvres
Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Book the next check in line with the report
- Clear leaves and litter away from the intake
- Look at the condensate drain whenever the unit is serviced
- Report water on the plant room floor
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.

Fixed quotes for AHU cleaning in Swalcliffe
You will get a fixed price before any work starts. It takes into account:
- The condition we find in the survey
- Whether we need access equipment or extra panels
- Whether it’s a one-off visit or part of a schedule
- The times the site is available
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
What to send for a quote
We can often survey from pictures. Try to include:
- The postcode and the type of business
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
- Problems your staff have spotted
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, call 0345 646 2711, or send details by email.
Common questions in Swalcliffe
Do you work at weekends in Swalcliffe?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Swalcliffe needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Can ventilation in schools around Swalcliffe be cleaned out of term?
Yes, holiday work suits schools best. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Swalcliffe. You can phone us on 0345 646 2711 or send us an email with the dates the site is empty.
Do you look at the system first?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
Do you have insurance?
Yes. Full insurance covers our work and have been trading since 2009.
How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
The process
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Rural roads and tight entrances are worth telling us about before a visit to Swalcliffe.
- We look at the unit and the plant area during the survey.
- 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.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload

What the work involves, part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that won’t bend or flatten the fins.
