Langenhoe AHU cleaning
AHU cleaning across Langenhoe and nearby, timed so the site keeps working and signed off in writing with photos.
- Coils clogged with dust and debris
- Blocked condensate drains and slimy trays
- Plant that has been serviced but not cleaned
What happens if it’s left?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Systems in rural buildings are often out of sight and out of mind.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.
Why us?
- A single point of contact for sites across the South East and London
- BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Fully insured
- Photo reports with every job

AHU cleaning in Langenhoe
We clean air handling units for buildings in Langenhoe and across Essex, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers heating and cooling coils, supply and extract fans and internal panels, and the jobs we see most are dirty filters cutting the airflow and units needing a clean before a new tenant or handover.
Somewhere as small as Langenhoe, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too across Essex. Work can be phased by floor, building or site around the people who use them.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.

Do you need AHU cleaning in Langenhoe?
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
Common reasons sites call us include:
- Intake sections clogged with outdoor debris
- Units that have only ever had filter changes
- Condensate trays that will not empty
- Air handling units due a clean after building work
Essex County Hospital, about 4.1 miles north, is the nearest hospital to Langenhoe, and healthcare sites of every size need their supply air kept clean.
Questions to ask before you book
- Whether a survey comes first
- Proof of insurance
- What paperwork you get at the end
- Whether they recommend a next date
What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- A single visit or a regular plan
- Travel, parking and unloading
- Site rules, permits and inductions
- Working hours and out-of-hours timing
The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before work begins, so there are no surprises.
Helping us quote
Many jobs can be priced from photos and some basics. Useful things to send:
- Wide pictures of the system and the area around it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any access panels or hatches you can see
- Any previous report or certificate
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
The process
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes from a few hours for a compact unit to a day or more for a large one. The timing of a visit to Langenhoe is set by you, and the travel is our side of the planning.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Dig out any earlier paperwork for the system
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool
Getting a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Aftercare tips
Here’s the after-treatment advice, short and simple:
- Store the TR19 paperwork where auditors can find it
- Look at the condensate drain whenever the unit is serviced
- Do not store bins or materials near the intake
- Plan the next inspection before the last report gets filed away
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

What is TR19?

How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Will the ventilation be off while you clean?
Yes, for the time we’re working on it. We can work evenings, overnight or at weekends to keep disruption down.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
