About our AHU cleaning in Picket Twenty
Our AHU cleans for sites in Picket Twenty cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. If you have units that have only ever had filter changes and filters that are clogged or overdue, we can help, from internal panels, dampers and louvres and drain trays onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Picket Twenty: your questions answered
Do you cover smaller places like Picket Twenty?
Yes. Villages and rural sites across the South East are part of our work, Picket Twenty included. The journey is planned ahead, so a few details about the route help.
Do you work at weekends in Picket Twenty?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Just give us a ring on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
Can you clean the ducts connected to the AHU?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
Is a quote from photos possible?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- File each AHU report in the maintenance log
- Keep the area around the fresh air intake clear
- Don’t ignore odours coming through the grilles
- Plan the next inspection before the last report gets filed away
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
What we’re called out for in Picket Twenty
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Keep an eye out for these warning signs:
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue
- Intake sections clogged with outdoor debris
- Dust built up on fan impellers
If you run a surgery, dental practice or care home near Picket Twenty, clean ventilation matters as much to you as to a hospital like Andover War Memorial Hospital (about 1.9 miles west).

When it’s something else
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Ductwork downstream of the unit, which is a separate clean
- Airflow problems caused by the system’s design
- Damaged coils beyond cleaning
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly.

Fixed quotes for AHU cleaning in Picket Twenty
Before we fix a price, we need to know a few things. We check:
- Where the site is and how we reach it
- How easy every part is to reach
- When the work can happen, such as evenings, overnight or weekends
- The size of the system
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.
What to send for a quote
To speed up the quote, send us:
- Your opening hours and when the area is out of use
- The postcode and the type of business
- Detail shots of panels, filters and grilles
- How we’d reach plant on a roof or in a plant room
Getting a quote doesn’t take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Why deal with it now?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. In a small place like Picket Twenty, a system that fails can take a site out of use.
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

How it works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. A few pictures of the system help us make the most of a visit to a place like Picket Twenty.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.

AHU cleaning in Picket Twenty: local notes
The FSA’s food hygiene register lists about 7 schools, colleges and universities, about 13 hospitals, care homes and childcare premises and about 4 hotels, B&Bs and guest houses with registered kitchens or food service within roughly a mile and a half of the centre of Picket Twenty. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Picket Twenty’s nearest hospital, Andover War Memorial Hospital, is about 1.9 miles west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Wherever a school like Pilgrims' Cross CofE Aided Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What the work involves, part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
