About our AHU cleaning in Colne Engaine
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. The work covers heating and cooling coils, dampers and louvres and filter sections, and people most often call us about blocked condensate drains and slimy trays and coils clogged with dust and debris.
For a building in or near Colne Engaine, access is agreed in advance and the visit is planned around the journey.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Honest limits
We will not sell you work that does not address the problem, so these are the things it will not cover:

- Problems with the unit’s controls or sensors
- Ventilation that was badly designed in the first place
If you’re not sure, just call 0345 646 2711 or send us an email and we will give you a straight answer before you book.

What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Report stiff or damaged access doors
- Keep the area around the fresh air intake clear
- Report water on the plant room floor
- Change filters on schedule and log each change
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
Do you need AHU cleaning in Colne Engaine?
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
It’s time to book a visit if you see:
- Blocked condensate drains and slimy trays
- Air handling units never cleaned inside
- Dust-coated heating and cooling coils
- Intake sections clogged with outdoor debris
Hospitals such as Halstead Hospital (about 2.3 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Colne Engaine are no different.

What we do, step by step
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. If the van will struggle with a lane or gateway near Colne Engaine, let us know and we will plan around it.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Agree a time when the area can be out of use
- Find the previous report, if there is one
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Common questions in Colne Engaine
Can the work in Colne Engaine be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Colne Engaine needn’t be disturbed. Let us know the hours you’re closed and we’ll book within them.
Will you come out to Colne Engaine?
Yes. Villages and rural sites across the South East are part of our work, Colne Engaine included. A survey first, from photos or a visit, means we arrive with the right kit.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
How often should an air handling unit be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.
Do you have insurance?
Yes. We’re fully insured, and we can share the details when you need them.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
Do you have a 24/7 line?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
Landlords, agents and facilities managers
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
Why act early in Colne Engaine
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. Clearing it now is a much smaller job. In a small place like Colne Engaine, a system that fails can take a site out of use.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
