How we handle AHU cleaning in Culverstone Green
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. Common call-outs are for dirty filters cutting the airflow and condensate trays that won’t empty, across dampers and louvres, supply and extract fans and internal panels.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Airflow problems caused by the system’s design
- The supply and extract ducts, quoted separately
- Problems with the unit’s controls or sensors
If you are not sure, just call 0345 646 2711, or send details by email and we’ll give you a straight answer before you book.

Why it’s worth doing now in Culverstone Green
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. In a place like Culverstone Green, ductwork and fans are easy to forget until something goes wrong.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before any work starts.

How the visit works
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. A few photos of the system help us make the most of a visit to a place like Culverstone Green.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Make sure someone can let us in and lock up afterwards
- Let us know about permits to work or site inductions
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Advice
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows 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 can diagnose it and quote.
Between visits
Simple habits between visits make a real difference. Our advice:
- Watch for drips or damp patches near the plant
- Store the TR19 paperwork where auditors can find it
- Book the next check in line with the report
- Report stiff or damaged access doors
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
Questions from Culverstone Green
Can the work in Culverstone Green be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. It means the site in Culverstone Green keeps running as normal. Your opening times are the first thing we ask for.
Can you get to a site in Culverstone Green?
Yes. Culverstone Green is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Every site has its own report.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can quote for both.
Can you price the work without visiting?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and we usually come back within one working day. If pictures aren’t enough, we will survey first.
Do you need to switch the unit off?
Yes, for the time we’re working on it. Out-of-hours work is available to keep disruption down.

Culverstone Green buildings and their air
Going by the FSA’s register, there are about 3 schools, colleges and universities serving food within 1.5 miles or so of the middle of Culverstone Green. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Culverstone Green, about 22 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.
Wherever a school like Culverstone Green Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
