East Sussex · Air handling unit cleaning
Air handling unit cleaning in Alciston, East Sussex
AHU cleaning in Alciston from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Odours coming through the supply air
- Dirty filters cutting the airflow
- Blocked condensate drains and slimy trays
Keeping the system healthy
After the visit, a few habits help the work last:
- Do not ignore odours coming through the grilles
- File each AHU report in the maintenance log
- Report water on the plant room floor
- Diary the inspection date recommended in the report
The report suggests a date for the next inspection or clean, based on what we found. 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.
AHU cleaning in Alciston, done properly
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, so cleaning the unit matters as much as cleaning the ducts. If you have units needing a clean before a new tenant or handover and blocked condensate drains and slimy trays, we can help, from heating and cooling coils, internal panels and drain trays onwards.
For a building in or near Alciston, access is agreed in advance and the visit is planned around the journey.
The paperwork matters as much as the work. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

FAQs for Alciston
Can you do AHU cleaning in Alciston?
Yes, Alciston is covered. To start, give us a ring on 0345 646 2711 or use the quote form with a few pictures of the system.
Do you work at weekends in Alciston?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you do ventilation duct cleaning too?
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 survey both on the same visit.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Every site has its own report.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
How do you protect the area?
Floors and surfaces near the work are sheeted before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
Why deal with it now?
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Out of sight is the usual reason a rural system goes too long without attention.
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before any work starts.

What affects the quote in Alciston
Every site gets its own quote. This is what makes a difference:
- Parking and loading at the site
- The size of the system
- The condition we find in the survey
- Site rules, permits and inductions
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
Asking for a quote
When you call or email, it’s useful to have:
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
- Any symptoms, from odd noises to smells or leaks
- Wide pictures of the system and the area around it
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
What happens on the day
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes one overnight shift for many single units, with bigger plant phased. Somewhere as small as Alciston, the date and timings are agreed with you well before the day.
- We start with a survey of the unit and a fixed quote for the work.
- 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.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
How to prepare
- Let us know when the site is closed or quiet
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
Get a fixed quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.
