- Dirty filters cutting the airflow
- Stale or musty smells from the ventilation
How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes anything from half a day for one small unit to several shifts for a plant room full of them. For a village or hamlet like Hunton Bridge, tell us about narrow lanes, gates and parking when you book.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Getting ready for the visit
- Tell us where we can park and unload
- Clear the space around the work
- Arrange a key holder or contact on site
How to get a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

AHU cleaning in Hunton Bridge, done properly
Our AHU cleans for sites in Hunton Bridge cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. We are often asked to deal with dust-coated heating and cooling coils and air handling units with blocked filters, across heating and cooling coils, internal panels and dampers and louvres.
For a building in or near Hunton Bridge, access is agreed in advance and the visit is planned around the journey.
The paperwork matters as much as the work. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What affects the quote in Hunton Bridge
The price is fixed before any work begins. It’s based on:
- How many systems or sites are involved
- Working hours and out-of-hours timing
- Any permits to work or inductions
- The size of the system
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or email us, and we will talk you through it.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Where the site is and what kind of site it is
- When the site is open and when it’s quiet
- Any symptoms, from odd noises to smells or leaks
- Where the plant sits or the system leaves the building, such as a roof or outside wall
We do not publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To start, ring 0345 646 2711, or email photos.

If you run an office near Kings Langley station, its supply ductwork can gather dust for years before anyone looks inside. Classrooms and halls at schools such as St Paul's Church of England Primary School are easiest to work in when pupils are away.

In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Questions from Hunton Bridge
Do you work at weekends in Hunton Bridge?
Yes, we can come after you close and finish before you open. It means the site in Hunton Bridge keeps running as normal. Tell us your opening hours when you ask for a quote.
Can you clean school ventilation in Hunton Bridge during the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 12 schools and colleges with food registrations within roughly a mile and a half of Hunton Bridge. You can ring 0345 646 2711 or drop us a line with the dates the site is empty.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
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.
Can you quote from pictures?
Yes, where the pictures show enough. If not, a site survey comes first, and the quote follows that.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with the details in the report.
Is Hunton Bridge in your area?
Yes. Our area takes in London and the counties of South East England, Hunton Bridge included.
Leave it or put it right?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. Somewhere as small as Hunton Bridge, losing a kitchen or building to a fault is felt by everyone who uses it.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, ring 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.

What the work involves, part by part
Internal casing and panels
We open each section through its doors and close them securely when we are done before the unit is handed back.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Honest limits
Some problems need a different service or another trade:
- Mechanical faults with motors, belts or bearings
- Coils that are corroded or leaking and need replacing
- Problems with the unit’s controls or sensors
Not sure which it is? You can phone us on 0345 646 2711 or send us an email and we’ll tell you honestly.
What we work on in Hunton Bridge
- Drain trays
- Supply and extract fans
- Heating and cooling coils
- Filter sections
- Dampers and louvres
- Internal panels
Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Change filters on schedule and log each change
- Diary the inspection date recommended in the report
- Do not store bins or materials near the intake
- Report stiff or damaged access doors
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
