AHU cleaning for kitchens and businesses in Portchester
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. Typical jobs include dust-coated heating and cooling coils and odours coming through the supply air, across supply and extract fans, internal panels and heating and cooling coils.
Smaller buildings around Portchester 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.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Managing agents and facilities teams in Portchester
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Make sure condensate is draining away
- Book the next check in line with the report
- Keep inspection doors on the unit in good order
- Keep the area around the fresh air intake clear
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
What the work involves, part by part
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe in agreement with the site.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Portchester questions
Can you work in Portchester outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Portchester does not have to lose a day’s trading. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
Do you do school ventilation cleaning in Portchester in the summer holidays?
Yes, and it’s the easiest time to do it. There are about 14 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Portchester. Send us your term dates when you phone us on 0345 646 2711 or email us, and we’ll fit the work in.
What if parts of the system cannot be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before any work starts.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we’ll quote them together.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
Do you look at the system first?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
When something else is needed
AHU cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- Dirty ducts beyond the unit itself
- Controls and BMS settings that run the unit
- Breakdowns that need a mechanical engineer
If you’re not sure, just ring 0345 646 2711 or send us an email and we will give you a straight answer before booking.

Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Queen Alexandra Hospital is the nearest hospital, about 2.3 miles east of Portchester. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you run an office near Portchester station, its supply ductwork can gather dust for years before anyone looks inside. Healthcare buildings such as Queen Alexandra Hospital, about 2.3 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Portchester, yours matters too. If you manage a school such as Castle Primary School, ventilation cleaning is best booked for the holidays.

A fixed price needs a few facts first. We look at:
- Whether we need access equipment or extra panels
- Whether several sites go on one quote
- How big the system is
- Site rules, permits and inductions
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before any work starts.
