Over Norton AHU cleaning
Need AHU cleaning in Over Norton? We survey first, give you a fixed quote and work around your opening hours, finishing with a written report and photos.
- Intake sections clogged with outdoor debris
- Dirty filters cutting the airflow
- Blocked condensate drains and slimy trays
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Flag stale or damp smells in the supply air
- Stick to the filter change plan
- Make sure condensate is draining away
- Do not store bins or materials near the intake
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
AHU cleaning in Over Norton
Where a building in Over Norton has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. If you have plant that needs cleaning after a refit and debris and leaves in the fresh air intake, we can help.
For a building in or near Over Norton, access is agreed in advance and the visit is planned around the journey.
Every visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.

What affects the quote in Over Norton
There’s no set price list, because no two systems are the same. What we look at:
- One-off work versus a regular cycle
- Whether we need access equipment or extra panels
- The size of the system
- Site rules, permits and inductions
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
When you call or email, it’s useful to have:
- Any access panels or hatches you can see
- Your last certificate, test record or report
- The times we could work without disrupting the site
- How we’d reach plant on a roof or in a plant room
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711, or send details by email.
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
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. With shared responsibility, good records help everyone.
What AHU cleaning cannot fix
A few issues sit outside what this work can do:
- A system that’s undersized for the building
- Leaking heating or cooling coils
- Problems with the unit’s controls or sensors
If you are not sure, just ring 0345 646 2711 or send us an email and we’ll give you a straight answer before booking.

What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes half a day to a full day per unit, with large plant planned over several shifts. Photos of the system and how to reach it help us plan a visit to Over Norton.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Mention any parking or loading restrictions
- Let us know when the site is closed or quiet
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Advice
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.

Do you work overnight in Over Norton?

What’s included in an AHU clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We will flag anything we notice during the clean.
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, out of hours if needed.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Over Norton buildings and their air
The FSA’s food hygiene register lists about 3 schools, colleges and universities, about 7 caring premises (care homes, nurseries and hospitals) and about 4 hotels, B&Bs and guest houses with registered kitchens or food service within roughly a mile and a half of the centre of Over Norton. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time.
In Over Norton, we look inside the system before deciding what needs cleaning. For schools like Holy Trinity Catholic School, the holidays are the usual time to inspect and clean ventilation.
