In-house cleaning or a specialist?
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
How we handle AHU cleaning in Cramhurst
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers heating and cooling coils, drain trays and internal panels, and common reasons people get in touch are dirty filters cutting the airflow and leaves and litter drawn into the unit.
For a building in or near Cramhurst, 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 photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

What affects the cost of AHU cleaning
You will get a fixed price before work begins. It takes into account:
- How big the system is
- Any permits to work or inductions
- The number of sites or systems
- When the work can happen, such as evenings, overnight or weekends
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.
Asking for a quote
You don’t need the technical terms. Just send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
To get a fixed quote, phone us on 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
Common problems we fix in Cramhurst
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
These are the problems we see most often:
- Dust built up on fan impellers
- Dirty coils holding back the airflow
- Units that have only ever had filter changes
- Debris and leaves in the fresh air intake
Milford Hospital, about 1.3 miles east, is the nearest hospital to Cramhurst, and healthcare sites of every size need their supply air kept clean.

AHU cleaning in Cramhurst: local notes
The FSA’s food hygiene register lists about 3 hospitals, care homes and childcare premises with registered kitchens or food service across Cramhurst and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Milford Hospital is the nearest hospital, about 1.3 miles east of Cramhurst. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Cramhurst, about 34 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.
If you run an office near Milford (Surrey) station, its supply ductwork can gather dust for years before anyone looks inside.

Part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare across Surrey. Work can be phased by floor, building or site around the people who use them.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.

How it works
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Cramhurst, the date and timings are agreed with you well before the day.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Let us know about parking and loading
- Plan for cooking equipment or plant to be off before we arrive
- Have your last certificate or report to hand
How to get a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.
