AHU cleaning in Frating Green
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. If you are dealing with air handling units never cleaned inside and dust-coated heating and cooling coils, we can put it right, from internal panels, drain trays and dampers and louvres onwards.
For a building in or near Frating Green, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.

Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Report water on the plant room floor
- Keep inspection doors on the unit in good order
- Store the TR19 paperwork where auditors can find it
- Flag stale or damp smells in the supply air
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.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
Common problems we fix in Frating Green
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
It’s time to book a visit if you see:
- Fan sections that haven’t been cleaned in years
- Plant that needs cleaning after a refit
- Leaves and litter drawn into the unit
- Coils clogged with dust and debris
An inspection comes first for any ventilation job around Frating Green, so the cleaning matches what’s there.

Why it’s worth doing now in Frating Green
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. It’s worth booking a check, because nobody sees inside a duct day to day.
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
