- Dust-coated heating and cooling coils
- Stale or musty smells from the ventilation
- Plant that needs cleaning after a refit
How the visit 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 floors and nearby surfaces are sheeted. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere like Copford, lanes, gates and parking are worth mentioning in advance.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Let us know about permits to work or site inductions
- Move anything stored near the system
- Have your last certificate or report to hand

Advice
AHU cleaning in Copford, done properly
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. Common call-outs are for condensate trays that won’t empty and stale or musty smells from the ventilation, on heating and cooling coils, filter sections and internal panels.
In a village or hamlet like Copford, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Report water on the plant room floor
- Keep inspection doors on the unit in good order
- Book the next check in line with the report
- Report musty smells from the vents right away
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

Common questions in Copford
Do you work overnight in Copford?
Yes, evening, overnight and weekend work is normal for us. That way a site in Copford does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Do you do school ventilation cleaning in Copford in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 4 schools and colleges with food registrations within roughly a mile and a half of Copford. Just call us on 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Do you survey before quoting?
Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.
How much does AHU cleaning cost in Copford?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
How often do AHUs need cleaning?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Do you do ventilation duct cleaning too?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
Honest limits

How we price AHU cleaning
Sites vary more than people expect. The main factors:
- The size of the system
- How many systems or sites are involved
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
What to send for a quote
You don’t need the technical terms. Just send:
- Photos showing the whole system and its surroundings
- Close-ups of filters, grilles, hatches or access panels
- The postcode and the type of business
- The times we could work without disrupting the site
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
What AHU cleaning looks like in Copford
There are about 4 schools, colleges and universities on the FSA’s food hygiene register in and around Copford, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Copford, about 46 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible. For Copford, the closest hospital is Essex County Hospital, roughly 3.9 miles east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
For schools like The Stanway School, the holidays are the usual time to inspect and clean ventilation. Workplaces around Marks Tey station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. If you run a surgery, dental practice or care home near Copford, clean ventilation matters as much to you as to a hospital like Essex County Hospital (about 3.9 miles east).

Landmarks near Copford

Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Part by part
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
