How it works
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave. Photos of the system and how to reach it help us plan a visit to Stone.
- We survey the unit from pictures or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Move anything stored near the system

Advice
AHU cleaning in Stone, done properly
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. We are often asked to deal with odours coming through the supply air and dust-coated heating and cooling coils, on filter sections, internal panels and drain trays.
Somewhere as small as Stone, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Signs you need AHU cleaning in Stone
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
What we’re most often called out for:
- Condensate trays that won’t empty
- Units that have only ever had filter changes
- Fan sections that haven’t been cleaned in years
- Air handling units with blocked filters
Whether the building is in Stone itself or nearby, filters, coils, drain trays and ducts are all part of the work.

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 helps show that the system is managed between specialist visits, alongside our reports.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Looking after it afterwards
To keep the system working properly between visits:
- Keep inspection doors on the unit in good order
- Diary the inspection date recommended in the report
- File each AHU report in the maintenance log
- Don’t ignore odours coming through the grilles
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Managing agents and facilities teams in Stone
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
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.
FAQs for Stone
Is Stone in your area for AHU cleaning?
Yes, Stone is within the area we cover across London and the South East. To start, call us on 0345 646 2711 or drop us a line with a few photos of the system.
Do you work in villages like Stone?
Yes. Villages and rural sites across the South East are part of our work, Stone included. The journey is planned ahead, so a few details about the route help.
Where does the waste go?
We take it away at the end of the visit. During the work, it’s contained so the area stays clean.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
How much does AHU cleaning cost in Stone?
It depends on the site, so we quote each one individually. To get one, call 0345 646 2711 or send us an email and tell us about the site and its opening hours.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
Do you give a certificate after the clean?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
What happens if you can’t reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.

What the work involves, part by part
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
Why act early in Stone
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, ready to show anyone who asks. It’s simpler to plan the work at Stone now than to arrange it in a hurry later.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.
