Your questions about AHU cleaning in St George's Hill
Can the work in St George's Hill be done at night or at weekends?
Yes, nights and weekends are routine for us. The site is handed back ready to open. When you call us on 0345 646 2711, or send details by email, mention when the site is quiet.
Can you get to a site in St George's Hill?
Yes. Villages and rural sites across the South East are part of our work, St George's Hill included. Photos of the system and directions to the site help us plan the visit.
Do you have insurance?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, with new panels fitted where needed.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
About our AHU cleaning in St George's Hill
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. If you have units needing a clean before a new tenant or handover and condensate trays that won’t empty, we can put it right, from internal panels, dampers and louvres and supply and extract fans onwards.
In a smaller place like St George's Hill, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Facilities teams in offices, schools and healthcare sites book us too in St George's Hill and across Surrey. Work can be phased by floor, building or site around the people who use them.
Do you need AHU cleaning in St George's Hill?
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
If you notice any of these, it’s worth a diagnosis:
- Air handling units with blocked filters
- Stale or musty smells from the ventilation
- Units needing a clean before a new tenant or handover
- Drain trays holding standing water
If you manage shops or offices close to Weybridge station, a TR19® Air inspection shows whether the ductwork needs cleaning.

How it works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. For a site near St George's Hill, the work is booked around your opening hours, evenings and weekends included.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- 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 pictures.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Find the previous report, if there is one
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

How the job changes from site to site
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so repairs can be planned.
In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Why act early in St George's Hill
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. It’s easy to lose track of when the work was last done on a quieter site.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.
