About our AHU cleaning in Ridgewell
Our AHU cleans for sites in Ridgewell cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. We are often asked to deal with coils clogged with dust and debris and blocked condensate drains and slimy trays, across dampers and louvres, heating and cooling coils and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What we do, step by step
Each visit runs to the same pattern: protect the area, make the system safe, carry out the AHU cleaning, clear away and hand over the paperwork. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Pictures of the system and its access let us plan the work in Ridgewell before we set off.
- 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.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Clear loose items from the work area
- Let us know when the site is closed or quiet
How to get a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Advice
Looking after it afterwards
So the system stays in good health:
- Book the next check in line with the report
- Look at the condensate drain whenever the unit is serviced
- Do not ignore odours coming through the grilles
- Keep inspection doors on the unit in good order
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
Ridgewell buildings and their air

Wherever a school like Ridgewell Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. For buildings in and around Ridgewell, TR19® Air cleaning starts with an inspection.

Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Leave it or put it right?
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. Our emergency line runs 24/7, but a planned visit to Ridgewell is calmer for everyone.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.

- The scale of the work
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before any work starts.

Honest limits
We’ll always give you a straight diagnosis, so here’s what AHU cleaning won’t do:
- A system that’s undersized for the building
- Controls and BMS settings that run the unit
- Breakdowns that need a mechanical engineer
If you’re not sure, just give us a ring on 0345 646 2711 or drop us a line and we’ll give you a straight answer.

Different parts, different methods
Rooftop and plant room units

Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
