Common questions in Shalden Green
Can you come to Shalden Green after we close?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Shalden Green needn’t be disturbed. Your opening times are the first thing we ask for.
Do you cover smaller places like Shalden Green?
Yes, we work in villages as well as towns, and Shalden Green is covered. A survey first, from photos or a visit, means we arrive with the right kit.
Where does the waste go?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
Do you repair air handling units?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
Can you clean the ducts connected to the AHU?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
AHU cleaning in Shalden Green, done properly
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. The work covers dampers and louvres, filter sections and supply and extract fans, and common reasons people get in touch are fan sections that haven’t been cleaned in years and plant that has been serviced but not cleaned.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Looking after it afterwards
Once we have finished, these simple steps help:
- Report water on the plant room floor
- Keep the certificate and photo report with the plant records
- Don’t ignore odours coming through the grilles
- Report stiff or damaged access doors
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
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, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Different parts, different methods
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.

- Mechanical faults with motors, belts or bearings

How the visit works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes half a day to a full day per unit, with large plant planned over several shifts. A few photos of the system help us make the most of a visit to a place like Shalden Green.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Agree a time when the area can be out of use
- Find the previous report, if there is one
- Move anything stored near the system

Multi-site and managed buildings
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
