Downton: your questions answered
Do you clean school ventilation in Downton in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Downton, the Food Standards Agency lists about 5 schools and colleges with registered kitchens within a mile and a half or so. You can call 0345 646 2711, or send details by email with the dates the site is empty.
Do you work overnight in Downton?
Yes, nights and weekends are routine for us. It means the site in Downton keeps running as normal. When you phone us on 0345 646 2711 or email us, mention when the site is quiet.
Do you repair air handling units?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.
What if parts of the system can’t be reached?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
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. Vent Hygiene Elite is run by BESCA and independently audited.
How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
What is TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
AHU cleaning in Downton, done properly
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. 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 air handling units with blocked filters and units that have only ever had filter changes, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
A written report with pictures follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Downton simpler. It’s worth booking a check, because nobody sees inside a duct day to day.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, call 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.

Do you need AHU cleaning in Downton?
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
Common reasons sites call us are:
- Units needing a clean before a new tenant or handover
- Plant that has been serviced but not cleaned
- Coils clogged with dust and debris
- Debris and leaves in the fresh air intake
Wherever a school like Hordle CofE (VA) Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Before booking anyone
- What paperwork you get at the end
- Proof of accreditation you can verify
- What insurance they carry
- What hours they’ll be on site
Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in Downton and across Hampshire. Work can be phased by floor, building or site around the people who use them.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
What the work involves, part by part
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.
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Fixed quotes for AHU cleaning in Downton
Before we fix a price, we need to know a few things. We check:
- The scale of the work
- The times the site is available
- The number of sites or systems
- Access, including roofs, risers and ceiling voids
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711 or email us, and we’ll explain what it covers.
Helping us quote
A few details help us quote accurately. With your enquiry, please include:
- Your opening hours and when the area is out of use
- Close-ups of filters, grilles, hatches or access panels
- Where the site is and what kind of site it is
- Photos showing the whole system and its surroundings
To help us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Then give us a ring on 0345 646 2711 or use the quote form.
The process
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, tidy up and leave you the report. On site, the work takes one overnight shift for many single units, with bigger plant phased. Photos of the system and how to reach it help us plan a visit to Downton.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- 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.
How to prepare
- Find the previous report, if there is one
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us the best time to work, such as after service or at a weekend
How to get a quote
Getting a quote does not take long. 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.
Advice
What staff can safely do
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
