How the job changes from site to site
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
How we handle AHU cleaning in Churt
If the units serving a building in Churt have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. Common call-outs are for units that have only ever had filter changes and dust-coated heating and cooling coils, across supply and extract fans, dampers and louvres and drain trays.
In a village or hamlet like Churt, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Signs you need AHU cleaning in Churt
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Look out for any of the following:
- Leaves and litter drawn into the unit
- Drain trays holding standing water
- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
Hospitals such as Chase Community Hospital (about 4.2 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Churt are no different.
What your quote should include
- Whether they’re fully insured
- How VAT is shown on the quote
- What happens if part of the system cannot be accessed
- Whether a written report and photos are included
Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare in Churt and across Surrey. Work can be phased by floor, building or site to keep disruption down.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.

Before you book, it helps to know what’s not included:
- Airflow problems caused by the system’s design
- Damaged coils beyond cleaning
- Dirty ducts beyond the unit itself
If in doubt, call 0345 646 2711 or drop us a line and we will say what we think before booking.

What else we do in Churt
What your team can do, and what needs us
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
How it works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes one overnight shift for many single units, with bigger plant phased. Rural roads and tight entrances are worth telling us about before a visit to Churt.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Clear loose items from the work area
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about site rules, permits or sign-in

What AHU cleaning looks like in Churt
About 4.2 miles south-west of Churt is Chase Community Hospital, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. Churt, about 39 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 manage a school such as St John's CofE Aided Infant School, ventilation cleaning is best booked for the holidays.

Landmarks near Churt
In Churt, that means kitchens and buildings near The Flashes and Crossways Inn and the streets around them. The nearest railway station is Haslemere station, roughly 4.3 miles south-east of the centre. Nearby you will also find Chase Community Hospital (4.2 miles south-west). Green spaces nearby include Upper Lake and Farnham Heath.
Why deal with it now?
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. It’s simpler to plan the work at Churt now than to arrange it in a hurry later.
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.
