AHU cleaning in Paulsgrove
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. We’re often asked to deal with plant that has been serviced but not cleaned and dirty filters cutting the airflow, on dampers and louvres, heating and cooling coils and filter sections.
Smaller buildings around Paulsgrove often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

AHU cleaning in Paulsgrove: local notes
There are about 16 schools, colleges and universities, about 18 caring premises (care homes, nurseries and hospitals) and about 4 hotels, B&Bs and guest houses on the FSA’s food hygiene register in and around Paulsgrove, up to about a mile and a half out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 1.1 miles east of Paulsgrove is Queen Alexandra Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you run a surgery, dental practice or care home near Paulsgrove, clean ventilation matters as much to you as to a hospital like Queen Alexandra Hospital (about 1.1 miles east).

In-house cleaning or a specialist?
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, next to our reports.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Signs you need AHU cleaning in Paulsgrove
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Look out for these warning signs:
- Debris and leaves in the fresh air intake
- Dust-coated heating and cooling coils
- Fan sections that haven’t been cleaned in years
- Units that have only ever had filter changes
If you manage a school such as Beacon View Primary Academy, ventilation cleaning is best booked for the holidays.

How the job changes from site to site
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that won’t bend or flatten the fins.
What we do, step by step
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, which takes half a day to a full day per unit, with large plant planned over several shifts. Your opening hours decide when we come to Paulsgrove, not ours.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us the best time to work, such as after service or at a weekend
- Clear loose items from the work area

What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Even a site near Paulsgrove that’s only busy part of the week needs its system checked on a schedule.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before work begins.

Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Watch for drips or damp patches near the plant
- Look at the condensate drain whenever the unit is serviced
- Do not store bins or materials near the intake
- Book the next check in line with the report
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
When something else is needed
Before booking, it helps to know what’s not included:
- Airflow problems caused by the system’s design
- Controls and BMS settings that run the unit
- Faulty motors, drives or bearings
If you are not sure, just ring 0345 646 2711 or email us and we’ll give you a straight answer before booking.

Questions from Paulsgrove
Can the work in Paulsgrove be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Paulsgrove needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
Can ventilation in schools around Paulsgrove be cleaned out of term?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 16 schools and colleges with food registrations within roughly a mile and a half of Paulsgrove. Just phone us on 0345 646 2711 or send us an email with your term dates and we will plan around them.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
How long does an AHU clean take?
It takes one overnight shift for many single units, with bigger plant phased. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
What about areas you can’t get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
What happens to the waste?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
