Common problems we fix in Chickney
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Chickney, that is air they breathe for hours at a time.
These are the problems we see most often:
- Drain trays holding standing water
- Air handling units with blocked filters
- Dirty fans and fan housings
- Coils clogged with dust and debris
Around Chickney, as anywhere, ventilation cleaning begins with an inspection.

How we handle AHU cleaning in Chickney
We clean air handling units for buildings in Chickney and across Essex, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Common call-outs are for air handling units never cleaned inside and air handling units with blocked filters, on filter sections, heating and cooling coils and dampers and louvres.
Work in a small place like Chickney starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What else we do in Chickney
Landlords, agents and facilities managers
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so records stay tidy.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. 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 half a day to a full day per unit, with large plant planned over several shifts. Rural roads and tight entrances are worth telling us about before a visit to Chickney.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- 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
- Clear the space around the work
- Dig out any earlier paperwork for the system
- Tell us where we can park and unload
Get a fixed quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
Advice
What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- What state the system is in
- When the work can happen, such as evenings, overnight or weekends
- Travel, parking and unloading
- The scale of the work
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
If you need AHU cleaning in Chickney, call us on 0345 646 2711 or email us. Let us know the site type and the opening hours, and send photos or your last report if you can. A fixed quote normally follows within one working day.
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Look at the condensate drain whenever the unit is serviced
- Make sure the unit’s access doors open easily
- Change filters on schedule and log each change
- Diary the inspection date recommended in the report
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.

Chickney questions
Do you offer AHU cleaning in Chickney?
Yes. Our area runs across London and the South East, Chickney included. Just call us on 0345 646 2711 or use the quote form with a few details of the site.
Do you cover smaller places like Chickney?
Yes. Villages and rural sites across the South East are part of our work, Chickney included. A survey first, from pictures or a visit, means we arrive with the right kit.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. Before we leave, we tidy up and clean down.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Can you quote from photos?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
When should our AHU next be cleaned?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
Different parts, different methods
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.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with photos.
In-house cleaning or a specialist?
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. Reaching it takes a specialist with the right equipment.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
