AHU cleaning in Colden Common
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. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. The work covers heating and cooling coils, filter sections and drain trays, and people most often call us about plant that needs cleaning after a refit and filters that are clogged or overdue.
In a place like Colden Common, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Colden Common: your questions answered
Can you work in Colden Common outside opening hours?
Yes, we can come after you close and finish before you open. It means the site in Colden Common keeps running as normal. Tell us your opening hours when you ask for a quote.
Do you offer AHU cleaning in Colden Common?
Yes. Our area runs across London and the South East, Colden Common included. You can call 0345 646 2711 or email us and tell us what needs doing.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Do you have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
What should I send you?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply call us on 0345 646 2711 or email us.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What if parts of the system cannot be reached?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
Keeping the system healthy
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Plan the next inspection before the last report gets filed away
- Change filters on schedule and log each change
- Note any water around the unit or leaks below it
- Report stiff or damaged access doors
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Why deal with it now?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. That makes the next inspection of a building in Colden Common simpler. Around Colden Common, a kitchen or building out of action is missed right away.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, ring 0345 646 2711 or send us an email for straight advice and a fixed quote.

What happens on the day
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes from a few hours for a compact unit to a day or more for a large one. Around Colden Common, access is normally simpler than in a town centre, though gates and roof access are worth mentioning.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
