AHU cleaning in Runcton
If the units serving a building in Runcton have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you’re dealing with coils clogged with dust and debris and plant that needs cleaning after a refit, we can put it right, from drain trays, internal panels and supply and extract fans onwards.
Work in a small place like Runcton starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Why act early in Runcton
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Out of sight is the usual reason a rural system goes too long without attention.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

Your questions about AHU cleaning in Runcton
Do you work overnight in Runcton?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Runcton needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Will you come out to Runcton?
Yes. Runcton is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
How much notice should we give?
Earlier is better, especially for out-of-hours work. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
What do you do with what you remove?
We take it away at the end of the visit. While we work, it’s kept contained to keep the area clean.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
Can you price the work without visiting?
Often, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
What we do, step by step
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. Pictures of the system and its access let us plan the work in Runcton before we set off.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- 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.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Let us know how we reach the system, including roofs, risers and plant rooms
- Have your last certificate or report to hand

Related advice
Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Fixed quotes for AHU cleaning in Runcton
We quote each job individually. These are the things that affect it:
- How many systems or sites are involved
- How easy every part is to reach
- The condition of the system
- Where the site is and how we reach it
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.
What we need to know
To speed up the quote, please include:
- The site address and the type of premises
- A few general shots of the system
- The times we could work without disrupting the site
- Your last certificate, test record or report
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Report water on the plant room floor
- File each AHU report in the maintenance log
- Plan the next inspection before the last report gets filed away
- Change filters on schedule and log each change
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
