How we handle AHU cleaning in Sheet
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. We’re often asked to deal with rooms that smell stuffy when the system runs and dust-coated heating and cooling coils, on filter sections, heating and cooling coils and dampers and louvres.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Do you need AHU cleaning in Sheet?
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Signs it’s time to call us include:
- Intake sections clogged with outdoor debris
- Coils clogged with dust and debris
- Air handling units due a clean after building work
- Fan sections that haven’t been cleaned in years
If you run a surgery, dental practice or care home near Sheet, clean ventilation matters as much to you as to a hospital like Petersfield Community Hospital (about 1.3 miles south-west).
Before you book anyone
- Whether inaccessible sections are listed on the report
- Proof of accreditation you can verify
- Whether they’re fully insured
- Whether they recommend a next date
Why it’s worth doing now in Sheet

Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.
What you get with us
- Work around your opening hours, with 24/7 emergency cover
- A fixed price before any work starts
- Accredited under CHAS and SafeContractor, with ISO 9001

How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Rural roads and tight entrances are worth telling us about before a visit to Sheet.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Tell us where we can park and unload
- Dig out any earlier paperwork for the system
- Make sure someone can let us in and lock up afterwards
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

Sheet questions
Do you work at weekends in Sheet?
Yes, out-of-hours work is a big part of what we do. It means the site in Sheet keeps running as normal. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Can ventilation in schools around Sheet be cleaned out of term?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 5 schools and colleges with food registrations within roughly a mile and a half of Sheet. Send us your term dates when you call 0345 646 2711, or email photos, and we will fit the work in.
Can you look after several sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Between visits
Simple habits between visits make a real difference. We recommend:
- Plan the next inspection before the last report gets filed away
- Store the TR19 paperwork where auditors can find it
- Report musty smells from the vents right away
- Make sure the unit’s access doors open easily
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
What staff can safely do
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.

- Any previous report or certificate
- How we’d reach plant on a roof or in a plant room
