AHU cleaning in Copford Green, done properly
Every supply and extract system relies on the air handling unit at its centre: 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, so cleaning the unit matters as much as cleaning the ducts. We are often asked to deal with units needing a clean before a new tenant or handover and debris and leaves in the fresh air intake, across drain trays, supply and extract fans and filter sections.
Somewhere as small as Copford Green, ducted ventilation is normally 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.
Good records are part of the job. You get a written report with photos after each visit, 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.

Leave it or put it right?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. It’s worth booking a check, because nobody sees inside a duct day to day.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we will price it together.

Copford Green: your questions answered
Is Copford Green within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Copford Green included. Let us know about access, parking and anything unusual about getting there when you book.
Can the work in Copford Green be done at night or at weekends?
Yes, we can come after you close and finish before you open. The work in Copford Green can fit around your hours. Just call us on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What happens if you can’t reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
How the job changes from site to site
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
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.
Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Clear leaves and litter away from the intake
- Book the next check in line with the report
- Flag stale or damp smells in the supply air
- Watch for drips or damp patches near the plant
When we have closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
When something else is needed
A few issues sit outside what this work can do:
- The supply and extract ducts, quoted separately
- Faulty motors, drives or bearings
- Damaged coils beyond cleaning
If you’re not sure, just call us on 0345 646 2711, or email photos and we will give you a straight answer.

Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.

What happens on the day
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. Photos of the system and how to reach it help us plan a visit to Copford Green.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- 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.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Let us know about permits to work or site inductions
- Arrange a key holder or contact on site
