In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
About our AHU cleaning in Sudbury
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. If you’re dealing with rooms that smell stuffy when the system runs and dust built up on fan impellers, we can put it right, from internal panels, supply and extract fans and filter sections onwards.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. In Sudbury, as elsewhere, cleaning starts with an inspection of what’s there.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Plan the next inspection before the last report gets filed away
- Stick to the filter change plan
- Clear leaves and litter away from the intake
- Do not ignore odours coming through the grilles
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.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
When to call us in Sudbury
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, a little more each month.
Any of these means the system needs a check-up:
- Stale or musty smells from the ventilation
- Blocked condensate drains and slimy trays
- Dirty coils holding back the airflow
- Units needing a clean before a new tenant or handover
For workplaces around Sudbury & Harrow Road station with mechanical ventilation, cleaning can be done in the evening or at weekends.

When it’s something else
AHU cleaning can’t fix everything, and we will tell you before any work starts. It won’t put right:
- Controls and BMS settings that run the unit
- Coils that are corroded or leaking and need replacing
- Ventilation that was badly designed in the first place
If you are not sure, just ring 0345 646 2711 or send us an email and we will give you a straight answer.

How it works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes one overnight shift for many single units, with bigger plant phased. Security desks and permits-to-work are routine in London, so let us know what your building in Sudbury needs from us.
- 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.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Move anything stored near the system
- Allow time for equipment near the work to be turned off and cool down

Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Getting kit to a London plant room typically means lifts, stairs and an agreed loading slot. For Sudbury, the closest hospital is Clementine Churchill Hospital, roughly 0.9 miles north-west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

FAQs for Sudbury
What do you need to know about parking in Sudbury?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit usually gets round them.

Yes, and it’s the easiest time to do it. The FSA’s register shows about 27 schools and colleges with food registrations within roughly a mile and a half of Sudbury. Just give us a ring on 0345 646 2711 or email us with your term dates and we’ll plan around them.

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Can you clean the AHU out of hours?
Yes. Evening, overnight and weekend work is all possible, so the building keeps running in the day.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and leave the area clean.
What happens to the waste?
We take it away when we go. During the work, it’s contained so the area stays clean.

What the work involves, part by part
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
