AHU cleaning in Warnford, done properly
If the units serving a building in Warnford have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. If you have dust built up on fan impellers and leaves and litter drawn into the unit, we can put it right.
Somewhere as small as Warnford, ducted ventilation is usually 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 photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

How the visit works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes a single shift for a typical unit, longer for large or heavily soiled ones. In a small place like Warnford, the journey is planned ahead and the visit arranged around the site’s hours.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Mention any locked doors, roof access or ceiling voids
- Clear the space around the work

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.
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Warnford: your questions answered
Can you get to a site in Warnford?
Yes, Warnford is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Can you work in Warnford outside opening hours?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. When you give us a ring on 0345 646 2711, or email photos, mention when the site is quiet.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Is a quote from pictures possible?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote usually follows within one working day. If pictures are not enough, we’ll survey first.
How do you protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
How long does it take to clean an air handling unit?
Expect it to take from a few hours for a compact unit to a day or more for a large one. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
What happens if you cannot reach some of it?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
What affects the quote in Warnford
The quote reflects the site in front of us. We take into account:
- A single visit or a regular plan
- Where the site is and how we reach it
- Site rules, permits and inductions
- The number of sites or systems
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- When the site is open and when it’s quiet
- Any access panels or hatches you can see
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
We do not publish a price list, because every site is different. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, give us a ring on 0345 646 2711, or send details by email.
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Why deal with it now?
Standing water in a drain tray doesn’t clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. A planned visit to Warnford is easier to arrange than an emergency callout.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.
What you get with us
- Every job surveyed first
- Work around your opening hours, with 24/7 emergency cover

Between visits
Think of this as the after-treatment advice, short and simple:
- Do not store bins or materials near the intake
- Store the TR19 paperwork where auditors can find it
- Keep filter changes on time and recorded
- Watch for drips or damp patches near the plant
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Common problems we fix in Warnford
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
Common reasons sites call us are:
- Plant that has been serviced but not cleaned
- Blocked condensate drains and slimy trays
- Dust-coated heating and cooling coils
- Air handling units due a clean after building work
In Warnford, supply and extract ducts are cleaned along with the units that serve them.
