AHU cleaning in Stondon Massey, done properly
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. Typical jobs include rooms that smell stuffy when the system runs and air handling units never cleaned inside, on dampers and louvres, heating and cooling coils and supply and extract fans.
In a village or hamlet like Stondon Massey, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
How it works
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a single shift for a typical unit, longer for large or heavily soiled ones. Seeing the system in pictures first means the trip to Stondon Massey can be planned properly.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Have your last certificate or report to hand
- Let us know when the site is closed or quiet
- Clear loose items from the work area
Ask for a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before we start.

Why act early in Stondon Massey
Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. Equipment tucked in a roof space or outbuilding near Stondon Massey rarely gets looked at unless someone books it.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before we start.

Different parts, different methods
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.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.

What the work covers
- Heating and cooling coils
- Filter sections
- Supply and extract fans
- Dampers and louvres
- Drain trays
- Internal panels
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Do not store bins or materials near the intake
- Diary the inspection date recommended in the report
- Check the drain tray is emptying during routine visits
- Flag stale or damp smells in the supply air
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
