AHU cleaning in Ringshall, done properly
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. If you are dealing with condensate trays that won’t empty and coils clogged with dust and debris, we can put it right, from heating and cooling coils, filter sections and internal panels onwards.
Somewhere as small as Ringshall, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Multi-site and managed buildings
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.
Ringshall questions
Do you work at weekends in Ringshall?
Yes, out-of-hours work is a big part of what we do. That way a site in Ringshall doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Do you clean school ventilation in Ringshall in the holidays?
Yes, holiday work suits schools best. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Ringshall. Booking early in the term gives the best choice of holiday dates.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.
What if parts of the system cannot be reached?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
How much notice should we give?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
What do you do with what you remove?
We take it away when we go. During the work, it’s contained so the area stays clean.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
What we are called out for in Ringshall
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Keep an eye out for any of the following:
- Fan sections that haven’t been cleaned in years
- Coils clogged with dust and debris
- Air handling units never cleaned inside
- Leaves and litter drawn into the unit
In Ringshall, we look inside the system before deciding what needs cleaning.
Before booking anyone
- If the quote is a fixed price or an estimate
- Whether the quote is based on a survey or pictures
- Whether they’re fully insured
- When the next visit should be, and why
What AHU cleaning can’t fix
In fairness, some problems need a different fix:
- Dirty ducts beyond the unit itself
- Leaking heating or cooling coils
- A system that’s undersized for the building
If in doubt, phone us on 0345 646 2711, or email photos and we’ll say what we think.
Parts of the system we cover
- Drain trays
- Filter sections
- Supply and extract fans
- Dampers and louvres
- Heating and cooling coils
- Internal panels
Why deal with it now?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. Out of sight is the usual reason a rural system goes too long without attention.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before work begins.

Keeping the system healthy
Results last longer with the right care. We suggest:
- Flag stale or damp smells in the supply air
- Report water on the plant room floor
- Check the drain tray is emptying during routine visits
- 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.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
How the visit works
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. A few pictures of the system help us make the most of a visit to a place like Ringshall.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Move anything stored near the system
- Plan for cooking equipment or plant to be off before we arrive
- Tell us the best time to work, such as after service or at a weekend

What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, 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: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
