How we handle AHU cleaning in Chipping Ongar
Our AHU cleans for sites in Chipping Ongar cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. Common call-outs are for dust built up on fan impellers and units needing a clean before a new tenant or handover, on heating and cooling coils, dampers and louvres and internal panels.
Smaller buildings around Chipping Ongar often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
For insurers and inspectors, the record counts. That’s 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.

How it works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes a single shift for a typical unit, longer for large or heavily soiled ones. For a site near Chipping Ongar, the work is booked around your opening hours, evenings and weekends included.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Before we arrive
- Move anything stored near the system
- Let us know about permits to work or site inductions
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before work begins.

Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Landlords, agents and facilities managers
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Why act early in Chipping Ongar
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. Booking now means the visit to Chipping Ongar is planned around you, not forced by a breakdown.
We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.
Why us?
- In business since 2009
- A written report with pictures after each visit
- One contact for all your sites in London and the South East
- Out-of-hours work and a 24/7 emergency line
Between visits
How long the results last depends on use and care. We suggest:
- Diary the inspection date recommended in the report
- Make sure condensate is draining away
- Keep the certificate and photo report with the plant records
- Report musty smells from the vents straight away
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
Do you need AHU cleaning in Chipping Ongar?
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Common reasons sites call us include:
- Dirty fans and fan housings
- Units that have only ever had filter changes
- Coils clogged with dust and debris
- Debris and leaves in the fresh air intake
School buildings such as Chipping Ongar Primary School are normally done in the holidays, so classrooms aren’t disturbed.

What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
Do you work with multi-site operators?

Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.

Floors and surfaces near the work are sheeted before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then give us a ring on 0345 646 2711 or send us an email.
Part by part
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
