Why it’s worth doing now in Great Chesterford
A slimy drain tray only gets worse. 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. Light use slows the build-up but does not stop it.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before work begins.

AHU cleaning in Great Chesterford, done properly
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. If you are dealing with fan sections that haven’t been cleaned in years and filters that are clogged or overdue, we can help.
Around a place like Great Chesterford, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

What else we do in Great Chesterford
Great Chesterford questions
Do you do school ventilation cleaning in Great Chesterford in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Great Chesterford. Booking early in the term gives the best choice of holiday dates.
Can you come to Great Chesterford after we close?
Yes, we can come after you close and finish before you open. It means the site in Great Chesterford keeps running as normal. Tell us your opening hours when you ask for a quote.
Do you have a 24/7 line?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
What information do you need?
A short description and a few pictures, with the address and opening hours. We’ll ask for anything else we need.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
Can you price the work without visiting?
Often, yes. With good photos, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
How it works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes a single shift for a typical unit, longer for large or heavily soiled ones. Visits to a place like Great Chesterford are planned ahead, so we arrive with what the survey says the job needs.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Mention any sign-in, permit or induction we need
- Make sure equipment near the work can be switched off and left to cool
- Move anything stored near the system
Get a fixed quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
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.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in Great Chesterford and across Essex. Larger estates can be phased building by building around the people who use them.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
How the job changes from site to site
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Keep inspection doors on the unit in good order
- Report musty smells from the vents right away
- Check the drain tray is emptying during routine visits
- Book the next check in line with the report
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.

Do you need AHU cleaning in Great Chesterford?
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Keep an eye out for any of the following:
- Air handling units with blocked filters
- Plant that has been serviced but not cleaned
- Dust-coated heating and cooling coils
- Debris and leaves in the fresh air intake
For schools like Great Chesterford Church of England Primary Academy, the holidays are the usual time to inspect and clean ventilation.
