How we handle AHU cleaning in Itchen
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. The work covers dampers and louvres, drain trays and internal panels, and common reasons people get in touch are dust built up on fan impellers and coils clogged with dust and debris.
Smaller buildings around Itchen often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Aftercare tips
Here’s the after-treatment advice, in brief:
- Book the next check in line with the report
- Report water on the plant room floor
- Stick to the filter change plan
- Look at the condensate drain whenever the unit is serviced
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
What AHU cleaning looks like in Itchen
Food Standards Agency data includes about 32 schools, colleges and universities, about 37 hospitals, care homes and childcare premises and about 4 hotels, B&Bs and guest houses in Itchen and the streets around it, up to about 1.5 miles out. Busy, occupied buildings like these are where clean supply air matters most. About 1.3 miles north-west of Itchen is Royal South Hants Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
School buildings such as Ludlow Junior School are normally done in the holidays, so classrooms aren’t disturbed. If you run a surgery, dental practice or care home near Itchen, clean ventilation matters as much to you as to a hospital like Royal South Hants Hospital (about 1.3 miles north-west).

Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Managing agents and facilities teams in Itchen
Facilities teams in offices, schools and healthcare sites book us too in Itchen and across Southampton. Larger estates can be phased building by building to keep disruption down.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
FAQs for Itchen
Can you come to Itchen after we close?
Yes. We work evenings, overnight and at weekends. It means the site in Itchen keeps running as normal. Just give us a ring on 0345 646 2711 or email us with your opening times and we will plan around them.
Do you cover smaller places like Itchen?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. We normally quote within one working day, and there’s a 24/7 line for emergencies.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Can you price the work without visiting?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.

Common problems we fix in Itchen
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Itchen, that is air they breathe for hours at a time.
Keep an eye out for any of the following:
- Air handling units due a clean after building work
- Dirty fans and fan housings
- Dust-coated heating and cooling coils
- Drain trays holding standing water
For workplaces around Woolston station with mechanical ventilation, cleaning can be done in the evening or at weekends.
