AHU cleaning in Old Netley
If the units serving a building in Old Netley have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. Common call-outs are for coils clogged with dust and debris and plant that needs cleaning after a refit, across supply and extract fans, internal panels and dampers and louvres.
Work in a small place like Old Netley starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What AHU cleaning looks like in Old Netley
Food Standards Agency records list about 18 schools, colleges and universities and about 22 care, childcare and hospital premises registered as food businesses across Old Netley and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Coldeast is the nearest hospital, about 2.3 miles south-east of Old Netley. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.

Advice
What we’re called out for in Old Netley
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
The symptoms we’re asked about most are:
- Rooms that smell stuffy when the system runs
- Drain trays holding standing water
- Dirty coils holding back the airflow
- Air handling units due a clean after building work
Classrooms and halls at schools such as Bursledon Church of England Infant School are easiest to work in when pupils are away.

Landlords, agents and facilities managers
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.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
FAQs for Old Netley
Can ventilation in schools around Old Netley be cleaned out of term?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 18 schools and colleges with food registrations within roughly a mile and a half of Old Netley. Send us your term dates when you phone us on 0345 646 2711 or email us, and we’ll fit the work in.
Will you come out to Old Netley?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
What do you clean inside the unit?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
What information do you need?
A short description and a few photos, with the address and opening hours. We will ask for anything else we need.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
How much notice should we give?
Earlier is better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
Part by part
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Internal casing and panels
We open each section through its doors and close them securely when we are done, and check every one is shut.
In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.

Between visits
After the visit, a few habits help the work last:
- File each AHU report in the maintenance log
- Stick to the filter change plan
- Watch for drips or damp patches near the plant
- Plan the next inspection before the last report gets filed away
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
