AHU cleaning in Boars Hill
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. We’re often asked to deal with dust-coated heating and cooling coils and stale or musty smells from the ventilation, on heating and cooling coils, supply and extract fans and filter sections.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Managing agents and facilities teams in Boars Hill
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs 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.
What we are called out for in Boars Hill
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and slime and smells soon follow.
Any of these means the system needs a check-up:
- Coils clogged with dust and debris
- Leaves and litter drawn into the unit
- Units that have only ever had filter changes
- Drain trays holding standing water
If you manage a school such as Wootton St Peter's Church of England Primary School, ventilation cleaning is best booked for the holidays.
What your quote should include
- Whether VAT is included
- Whether the work can be done while the site is closed
- What records you’ll receive afterwards
- If they look at the system before pricing
Looking after it afterwards
A little care between visits keeps the system in better shape. Our advice:
- File each AHU report in the maintenance log
- Report musty smells from the vents right away
- Keep the area around the fresh air intake clear
- Look at the condensate drain whenever the unit is serviced
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
What happens on the day
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. In a small place like Boars Hill, the journey is planned ahead and the visit arranged around the site’s hours.
- The survey covers the unit, its access and how it can be shut down.
- 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.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Find the previous report, if there is one
- Let us know about parking and loading
- Clear the space around the work

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, you get a fixed price before any work starts.

Boars Hill: your questions answered
Do you work overnight in Boars Hill?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just call us on 0345 646 2711 or send us an email with your opening times and we will plan around them.
Do you cover Boars Hill for AHU cleaning?
Yes. We work across London and the South East, and Boars Hill is part of that. A fixed quote typically follows within one working day of the survey details.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.
Do you repair air handling units?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Call us any time and explain what’s happened.
Are you fully insured?
Yes, we are fully insured. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Honest limits
To be straight with you, some problems need a different fix:
- Controls and BMS settings that run the unit
- Airflow problems caused by the system’s design
- Faulty motors, drives or bearings
Not sure which it is? You can ring 0345 646 2711 or use the quote form and we will tell you honestly before you book.
What the work covers
- Filter sections
- Heating and cooling coils
- Dampers and louvres
- Supply and extract fans
- Drain trays
- Internal panels
What staff can safely do
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. Reaching it takes a specialist with the right equipment.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Why deal with it now?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Our emergency line runs 24/7, but a planned visit to Boars Hill is calmer for everyone.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Why Boars Hill businesses choose us
