AHU cleaning for kitchens and businesses in Crow
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. The work covers drain trays, internal panels and dampers and louvres, and the jobs we see most are odours coming through the supply air and blocked condensate drains and slimy trays.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Why act early in Crow
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. In a place like Crow, ductwork and fans are easy to forget until something goes wrong.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Why us?
- A fixed price before any work starts
- We are fully insured
- CHAS, SafeContractor and ISO 9001
- We diagnose before we treat
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Flag stale or damp smells in the supply air
- Report stiff or damaged access doors
- Report water on the plant room floor
- File each AHU report in the maintenance log
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
FAQs for Crow
Can ventilation in schools around Crow be cleaned out of term?
Yes, out-of-term visits are normal for schools. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Crow. Just ring 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Do you cover smaller places like Crow?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Can you come out in an emergency?
Yes, any time. 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?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and the report recommends a next date.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Common problems we fix in Crow
Whatever surrounds a building in Crow, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
What we’re most often called out for:
- Blocked condensate drains and slimy trays
- Dirty filters cutting the airflow
- Dirty fans and fan housings
- Coils clogged with dust and debris
Healthcare ventilation, from large hospitals like St Leonard's Hospital (about 4.3 miles west) to small clinics, depends on clean filters, coils and ducts.

What happens on the day
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work 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 Crow, let us know and we’ll plan around it.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Clear loose items from the work area
- Mention any parking or loading restrictions
- Let us know when the site is closed or quiet
