AHU cleaning in Warsash
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you are dealing with plant that has been serviced but not cleaned and air handling units due a clean after building work, we can put it right, from supply and extract fans, dampers and louvres and filter sections onwards.
Visits to a place like Warsash are fitted around opening hours. The method doesn’t change: inspect first, clean, then record what was done.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Ventilation in Warsash buildings
Food Standards Agency data includes about 5 schools, colleges and universities and about 15 caring premises (care homes, nurseries and hospitals) in and around Warsash, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 0.9 miles north of Warsash is Coldeast, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
If you manage a school such as Hook-With-Warsash Church of England Academy, ventilation cleaning is best booked for the holidays.

Why deal with it now?
If people in a building in Warsash complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. Around Warsash, a kitchen or building out of action is missed right away.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are unsure, call us on 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.

What we do, step by step
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. Everything the job in Warsash needs is worked out beforehand, from the survey.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Name a contact who can let us in at the agreed time
- Tell us where we can park and unload
Getting a quote
Getting a quote does not take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

FAQs for Warsash
Can a school’s ventilation in Warsash be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 5 schools and colleges with food registrations within roughly a mile and a half of Warsash. Send us your term dates when you give us a ring on 0345 646 2711, or email photos, and we’ll fit the work in.
Can you get to a site in Warsash?
Yes, we work in villages as well as towns, and Warsash is covered. Just mention lanes, gates or anything else about the site when you book.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
How long does it take to clean an air handling unit?
Typically the clean takes a single shift for a typical unit, longer for large or heavily soiled ones. The shutdown is planned to fit, including evenings or weekends.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Do you work evenings or weekends?
Yes, if daytime working is not practical. Tell us when the unit can go off and we will work to that.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
How the job changes from site to site
Drain trays
Older trays can corrode and start leaking. We record their condition with pictures so repairs can be planned.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Make sure condensate is draining away
- Flag stale or damp smells in the supply air
- Watch for drips or damp patches near the plant
- Book the next check in line with the report
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 Warsash
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’s the air they breathe for hours on end.
What we’re most often called out for:
- Units that have only ever had filter changes
- Dirty filters cutting the airflow
- Rooms that smell stuffy when the system runs
- Dust built up on fan impellers
Hospitals such as Coldeast (about 0.9 miles north) show how much a building can rely on clean ventilation, and smaller healthcare sites near Warsash are no different.
Questions to ask before booking
- Whether they’re fully insured
- Which accreditations they hold, and whether you can check them
- What happens if part of the system can’t be accessed
- Whether they recommend a next date
Landlords, agents and facilities managers
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
