Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
How we handle AHU cleaning in Highcliffe
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. If you are dealing with debris and leaves in the fresh air intake and stale or musty smells from the ventilation, we can help.
Smaller buildings around Highcliffe often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What else we do in Highcliffe
Aftercare tips
A little care between visits keeps the system in better shape. Our advice:
- Book the next check in line with the report
- Don’t ignore odours coming through the grilles
- Look at the condensate drain whenever the unit is serviced
- Change filters on schedule and log each change
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Different parts, different methods
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
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.
What happens on the day
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. A site near Highcliffe usually has room to park, so the questions are about access to the system and your hours.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
- Tell us about site rules, permits or sign-in

What we’re called out for in Highcliffe
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
Look out for these warning signs:
- Dust built up on fan impellers
- Air handling units with blocked filters
- Condensate trays that will not empty
- Rooms that smell stuffy when the system runs
Wherever a school like All Saints Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Questions to ask before booking
- Proof of accreditation you can verify
- Whether the figure could change on the day
- Whether the work can be done while the site is closed
- When the next visit should be, and why
