AHU cleaning in Shawford, done properly
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers heating and cooling coils, drain trays and supply and extract fans, and people most often call us about leaves and litter drawn into the unit and fan sections that haven’t been cleaned in years.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Honest limits
AHU cleaning can’t fix everything, and we’d rather say so up front. It won’t put right:
- Coils that are corroded or leaking and need replacing
- Problems with the unit’s controls or sensors
- Breakdowns that need a mechanical engineer
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly before booking.
Parts of the system we cover
- Dampers and louvres
- Internal panels
- Supply and extract fans
- Drain trays
- Filter sections
- Heating and cooling coils
When to call us in Shawford
Filters catch most of the dust, but not all of it. 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:
- Air handling units never cleaned inside
- Dirty filters cutting the airflow
- Dirty coils holding back the airflow
- Dust built up on fan impellers
Classrooms and halls at schools such as Compton All Saints Church of England Primary School are easiest to work in when pupils are away.
Questions to ask before you book
- What hours they’ll be on site
- What paperwork you get at the end
- How VAT is shown on the quote
- Whether the figure could change on the day
What affects the quote in Shawford
You will get a fixed price before work begins. It’s based on:
- Any permits to work or inductions
- How many systems or sites are involved
- Working hours and out-of-hours timing
- What state the system is in
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.
What we need to know
To help us quote quickly, send us:
- Any access panels or hatches you can see
- Where the site is and what kind of site it is
- Photos showing the whole system and its surroundings
- Problems your staff have spotted
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
Ventilation in Shawford buildings
There are about 4 care, childcare and hospital premises on the FSA’s food hygiene register within roughly a mile and a half of the centre of Shawford. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Shawford’s nearest hospital, Royal Hampshire County Hospital, is about 2.7 miles north. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
If you run an office near Shawford station, its supply ductwork can gather dust for years before anyone looks inside. If you run a surgery, dental practice or care home near Shawford, clean ventilation matters as much to you as to a hospital like Royal Hampshire County Hospital (about 2.7 miles north).

Keeping the system healthy
After the visit, a few habits help the work last:
- Check the drain tray is emptying during routine visits
- Keep filter changes on time and recorded
- Keep the certificate and photo report with the plant records
- Report water on the plant room floor
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
Shawford questions
Can a school’s ventilation in Shawford be done out of term time?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Shawford. Send us your term dates when you give us a ring on 0345 646 2711 or use the quote form, and we’ll fit the work in.
Do you cover smaller places like Shawford?
Yes. Shawford is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. For a quote, call 0345 646 2711 or use the quote form with the site type, opening hours and a few pictures.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with photos where it helps.
Do you offer emergency callouts?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.
Can you clean the AHU out of hours?
Yes, wherever it helps the building. Tell us when the unit can go off and we will work to that.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.

Managing agents and facilities teams in Shawford
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Why act early in Shawford
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. A fault that closes a site in a village like Shawford affects everyone who depends on it.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.

- 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.
- We take after photos and issue the certificate and report.
