AHU cleaning in Criddlestyle
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. We are often asked to deal with condensate trays that won’t empty and leaves and litter drawn into the unit, on dampers and louvres, heating and cooling coils and filter sections.
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.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Common questions in Criddlestyle
Do you work overnight in Criddlestyle?
Yes. We work evenings, overnight and at weekends. The work in Criddlestyle can fit around your hours. Tell us your opening hours when you ask for a quote.
Can you get to a site in Criddlestyle?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Do you have a 24/7 line?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.

Multi-site and managed buildings
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
When to call us in Criddlestyle
Whatever surrounds a building in Criddlestyle, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
It’s time to book a visit if you see:
- Plant that needs cleaning after a refit
- Dust-coated heating and cooling coils
- Dirty filters cutting the airflow
- Plant that has been serviced but not cleaned
If you manage a school such as The Burgate School and Sixth Form, ventilation cleaning is best booked for the holidays.
What your quote should include

- Whether they recommend a next date
- How VAT is shown on the quote
- When they can work, and whether that is outside your opening hours
Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Between visits
Think of this as the after-treatment advice, in brief:
- Look at the condensate drain whenever the unit is serviced
- Book the next check in line with the report
- Keep filter changes on time and recorded
- Keep the area around the fresh air intake clear
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Why deal with it now?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. That makes the next inspection of a building in Criddlestyle simpler. Out of sight is the usual reason a rural system goes too long without attention.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will go through it with you.

When it’s something else
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It does not solve:
- Ductwork downstream of the unit, which is a separate clean
- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils
If you’re not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer before booking.
