AHU cleaning for kitchens and businesses in Little Ann
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. We are often asked to deal with odours coming through the supply air and air handling units never cleaned inside, on dampers and louvres, filter sections and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Day-to-day cleaning is something your team can do: 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, and that is where we come in.
How the job changes from site to site
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey, before we quote.
What we are called out for in Little Ann
Whatever surrounds a building in Little Ann, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
It’s time to book a visit if you see:
- Dust-coated heating and cooling coils
- Plant that has been serviced but not cleaned
- Drain trays holding standing water
- Rooms that smell stuffy when the system runs
If you run a surgery, dental practice or care home near Little Ann, clean ventilation matters as much to you as to a hospital like Andover War Memorial Hospital (about 2.2 miles north-east).
Questions to ask before you book
- What insurance they carry
- Which accreditations they hold, and whether you can check them
- Whether a written report and pictures are included
- Whether the quote shows VAT
What we do, step by step
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. If the van will struggle with a lane or gateway near Little Ann, let us know and we will plan around it.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Let us know when the site is closed or quiet
- Find the previous report, if there is one

Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.

Little Ann: your questions answered
Can you come to Little Ann after we close?
Yes, nights and weekends are routine for us. The work in Little Ann can fit around your hours. Let us know the hours you are closed and we will book within them.
Is Little Ann within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Little Ann included. Photos of the system and directions to the site help us plan the visit.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
How far ahead should we book?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Report musty smells from the vents right away
- Store the TR19 paperwork where auditors can find it
- Check the drain tray is emptying during routine visits
- Keep inspection doors on the unit in good order
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Managing agents and facilities teams in Little Ann
Facilities teams in offices, schools and healthcare sites book us too in Little Ann and across Hampshire. Larger estates can be phased building by building to keep disruption down.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
