AHU cleaning for kitchens and businesses in Copnor
We clean air handling units for buildings in Copnor and across Portsmouth, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers supply and extract fans, internal panels and heating and cooling coils, and common reasons people get in touch are plant that has been serviced but not cleaned and rooms that smell stuffy when the system runs.
Visits to a place like Copnor are fitted around opening hours. The method does not change: inspect first, clean, then record what was done.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Ventilation in Copnor buildings
Going by the FSA’s register, there are about 30 schools, colleges and universities, about 32 caring premises (care homes, nurseries and hospitals) and about 4 hotels and guest houses serving food in Copnor and the streets around it, up to about 1.5 miles out. Busy, occupied buildings like these are where clean supply air matters most. For Copnor, the closest hospital is St Mary's Hospital, roughly 0.7 miles south. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Healthcare buildings such as St Mary's Hospital, about 0.7 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Copnor, yours matters too. For schools like Westover Primary School, the holidays are the usual time to inspect and clean ventilation.
Copnor is about 1 mile east of Portsmouth, in Portsmouth. Anywhere in PO3, we can take on AHU cleaning. Copnor is one of 19 towns, villages and districts in Portsmouth we cover for AHU cleaning.
AHU cleaning in PO3, PO2 and PO1 is surveyed, quoted and booked the same way as anywhere else. That includes premises on New Road, Lynn Road and Byron Road and nearby roads. You’ll find Copnor on the A288, so it’s easy for us to get to for out-of-hours visits. Close by, we work in Baffins (1 mile south-east), Kingston (1 mile south), Portsmouth (1 mile west), Fratton (1 mile south-west) and North End (1 mile north-west).
Around Copnor
Typical jobs here are in premises near The Jolly Taxpayer pub, Alexandra Park and St Edmund's Catholic School and the streets around them. Copnor’s nearest station is Fratton station, roughly 1.1 miles south-west. A little further out are The Bridge Shopping Centre (1.1 miles south-west) and St Mary's Hospital (0.7 miles south). Not far away are Milton Locks and Portsdown Hill.
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Your questions about AHU cleaning in Copnor
Do you clean school ventilation in Copnor in the holidays?
Yes, holiday work suits schools best. Around Copnor, the Food Standards Agency lists about 30 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you give us a ring on 0345 646 2711 or drop us a line, and we’ll fit the work in.
Can the work in Copnor be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Copnor keeps running as normal. Your opening times are the first thing we ask for.
Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Do you need to switch the unit off?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
Do you survey before quoting?
Yes, every time. 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.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
How long does it take to clean an air handling unit?
The work takes one overnight shift for many single units, with bigger plant phased. Bigger units can be phased, so call us on 0345 646 2711, or send details by email to talk it through.
Why deal with it now?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, ready to show anyone who asks. You choose the date of a planned visit, and a breakdown never asks.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before we start.
Why us?

- Trading since 2009

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Honest limits
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Controls and BMS settings that run the unit
- Faulty motors, drives or bearings
- Coils that are corroded or leaking and need replacing
If you are not sure, just give us a ring on 0345 646 2711 or use the quote form and we will give you a straight answer before booking.
Where we work
- Supply and extract fans

What else we do in Copnor
What affects the cost of AHU cleaning
Your quote is based on your site. We take into account:
- The scale of the work
- The number of sites or systems
- Whether we need access equipment or extra panels
- What state the system is in
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, give us a ring on 0345 646 2711 or drop us a line, and we’ll talk you through it.
What to send for a quote
When you contact us, these details help:
- A few general shots of the system
- Your opening hours and when the area is out of use
- Any previous report or certificate
- The postcode and the type of business
For a fixed quote, ring 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
What happens on the day
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. Everything the job in Copnor needs is worked out beforehand, from the survey.
- 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.
Before we arrive
- Name a contact who can let us in at the agreed time
- Dig out any earlier paperwork for the system
- Mention any sign-in, permit or induction we need
Ask for a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Report water on the plant room floor
- Keep the certificate and photo report with the plant records
- Make sure condensate is draining away
- Make sure the unit’s access doors open easily
When we have closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
