Why act early in Birdham
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. If the system at a site near Birdham fails, there may be nowhere nearby to move to.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.

AHU cleaning in Birdham
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers supply and extract fans, filter sections and heating and cooling coils, and people most often call us about drain trays holding standing water and rooms that smell stuffy when the system runs.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What affects the cost of AHU cleaning
A fixed price needs a few facts first. We look at:
- Whether several sites go on one quote
- Site rules, permits and inductions
- Access, including roofs, risers and ceiling voids
- The times the site is available
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, call 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Your last certificate, test record or report
- When the site is open and when it’s quiet
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
If you need AHU cleaning in Birdham, call us on 0345 646 2711 or email us. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. A fixed quote usually follows within one working day.

In-house cleaning or a specialist?
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. The inside of ducts and units needs a specialist.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
What happens on the day
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Visits to a village like Birdham are booked in advance, at a time that suits whoever runs the site.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Arrange a key holder or contact on site

Related advice
What the work involves, part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Common questions in Birdham
Can a school’s ventilation in Birdham be done out of term time?
Yes, out-of-term visits are normal for schools. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Birdham, it pays to plan holiday dates ahead. Send us your term dates when you call 0345 646 2711, or email photos, and we’ll fit the work in.
Is Birdham within the area you cover?
Yes, we work in villages as well as towns, and Birdham is covered. Just mention lanes, gates or anything else about the site when you book.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after pictures. Keep them in the maintenance log.
How much notice do you need?
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.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
Do you have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
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 law, but it’s the benchmark.
Aftercare tips
Here’s the after-treatment advice, in brief:
- Book the next check in line with the report
- Clear leaves and litter away from the intake
- Report musty smells from the vents straight away
- Store the TR19 paperwork where auditors can find it
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
When to call us in Birdham
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Look out for any of the following:
- Plant that has been serviced but not cleaned
- Filters that are clogged or overdue
- Plant that needs cleaning after a refit
- Drain trays holding standing water
Healthcare buildings such as St Richard's Hospital, about 4.4 miles north-east, depend on their ventilation; if you manage a surgery, clinic or care home near Birdham, yours matters too.
