AHU cleaning in Smeeth
An air handling unit is the heart of a building’s ventilation: 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, which is why we clean the unit itself, not just the ducts. Typical jobs include dirty coils holding back the airflow and air handling units due a clean after building work, across drain trays, filter sections and supply and extract fans.
In a village or hamlet like Smeeth, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. Photos of the system and how to reach it help us plan a visit to Smeeth.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Dig out any earlier paperwork for the system
- Allow time for equipment near the work to be turned off and cool down

Common problems we fix in Smeeth
Dirt in an AHU matters in two ways: 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 Smeeth, that’s air they breathe for hours at a time.
Look out for any of the following:
- Coils clogged with dust and debris
- Dust built up on fan impellers
- Air handling units with blocked filters
- Odours coming through the supply air
For schools like Smeeth Community Primary School, the holidays are the usual time to inspect and clean ventilation.

When something else is needed
It’s worth knowing the limits before booking:
- Ventilation that was badly designed in the first place
- Mechanical faults with motors, belts or bearings
- Coils that are corroded or leaking and need replacing
If you’re not sure, just ring 0345 646 2711, or send details by email and we will give you a straight answer.

Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
What happens if it’s left?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. It’s worth booking a check, because nobody sees inside a duct day to day.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Why us?
- Fixed quotes, usually within one working day
- CHAS and SafeContractor accredited, with ISO 9001

Your questions about AHU cleaning in Smeeth
Can the work in Smeeth be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. It means the site in Smeeth keeps running as normal. Your opening times are the first thing we ask for.
Do you work in villages like Smeeth?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
What does AHU cleaning cost?
We do not 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. You get a fixed price before work begins.
What information do you need?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Do you need to switch the unit off?
Yes, for the time we’re working on it. Out-of-hours work is available so the building isn’t left without ventilation when it’s busy.
Can you price the work without visiting?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
How much notice should we give?
Earlier is better, especially for out-of-hours work. We normally quote within one working day, and there’s a 24/7 line for emergencies.
Aftercare tips
Once we have finished, these simple steps help:
- Book the next check in line with the report
- Note any water around the unit or leaks below it
- Make sure condensate is draining away
- Keep the area around the fresh air intake clear
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
