How we handle AHU cleaning in Up Nately
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. If you have condensate trays that won’t empty and debris and leaves in the fresh air intake, we can put it right, from heating and cooling coils, filter sections and supply and extract fans onwards.
In a village or hamlet like Up Nately, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Common problems we fix in Up Nately
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and that is where slime and odours start.
The symptoms we’re asked about most include:
- Air handling units with blocked filters
- Rooms that smell stuffy when the system runs
- Air handling units due a clean after building work
- Debris and leaves in the fresh air intake
Wherever a school like Robert May's School has ducted ventilation, a half-term visit keeps the work out of lesson time.

FAQs for Up Nately
Do you work overnight in Up Nately?
Yes. We work evenings, overnight and at weekends. The work in Up Nately can fit around your hours. When you give us a ring on 0345 646 2711, or send details by email, mention when the site is quiet.
Do you offer AHU cleaning in Up Nately?
Yes. Our area runs across London and the South East, Up Nately included. Just phone us on 0345 646 2711 or email us with a few details of the site.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
Can you price the work without visiting?
In many cases, 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.
Is there a survey before the work?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
How long does an AHU clean take?
Expect it to take one overnight shift for many single units, with bigger plant phased. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
How it works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. Pictures of the system and its access let us plan the work in Up Nately before we set off.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- 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 photos.
Preparing for the visit
- Arrange a key holder or contact on site
- Have your last certificate or report to hand
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
Getting a quote doesn’t take long. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

What else we do in Up Nately
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
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.
What happens if it’s left?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. With notice, the visit to Up Nately can be fitted around your bookings and events.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before any work starts.

Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Report water on the plant room floor
- Store the TR19 paperwork where auditors can find it
- Make sure condensate is draining away
- Don’t store bins or materials near the intake
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
