Findon Valley: your questions answered
Can a school’s ventilation in Findon Valley be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Findon Valley, it pays to plan holiday dates ahead. You can call 0345 646 2711, or email photos with the dates the site is empty.
Do you cover smaller places like Findon Valley?
Yes, we work in villages as well as towns, and Findon Valley is covered. Just mention lanes, gates or anything else about the site when you book.
How often should an air handling unit be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
Can you clean without disrupting the building?
Yes, wherever it helps the building. We plan the shutdown window with you.
Can you price the work without visiting?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
AHU cleaning for kitchens and businesses in Findon Valley
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 heating and cooling coils, drain trays and supply and extract fans, and people most often call us about plant that has been serviced but not cleaned and rooms that smell stuffy when the system runs.
For a building near Findon Valley, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What affects the quote in Findon Valley
Sites vary more than people expect. What affects the quote:
- Where the site is and how we reach it
- How big the system is
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.
What to send for a quote
There’s no need for technical detail. It helps if you can send:
- Where the site is and what kind of site it is
- Problems your staff have spotted
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
For a fixed quote, phone us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We normally come back within one working day.
The process
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Because the survey comes first, a visit to Findon Valley can normally be finished without a second trip.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Arrange a key holder or contact on site
- Make sure equipment near the work can be switched off and left to cool
- Agree a time when the area can be out of use
How to get a quote
Quotes are quick. Call or email with a few details and you’ll usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

- Faulty motors, drives or bearings
- Ventilation that was badly designed in the first place
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we will tell you honestly.

Managing agents and facilities teams in Findon Valley
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.

Leave it or put it right?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Booking now means the visit to Findon Valley is planned around you, not forced by a breakdown.
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before work begins.
What you get with us
- In business since 2009
- We diagnose before we treat
- CHAS, SafeContractor and ISO 9001
- Photo reports with every job
What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Looking after it afterwards
So the system stays in good health:
- Stick to the filter change plan
- Report water on the plant room floor
- Keep inspection doors on the unit in good order
- Keep the certificate and photo report with the plant records
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
