AHU cleaning in Alfriston
Every supply and extract system relies on the air handling unit at its centre: 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’re dealing with fan sections that haven’t been cleaned in years and dust-coated heating and cooling coils, we can put it right.
Work in a small place like Alfriston starts with agreeing access and timings.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What affects the quote in Alfriston
The survey tells us what the work involves. We look at:
- The times the site is available
- Whether we need access equipment or extra panels
- Where the site is and how we reach it
- Whether it’s a one-off visit or part of a schedule
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
Helping us quote
You don’t need the technical terms. Just send:
- Where the site is and what kind of site it is
- Wide photos of the system and the area around it
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
We do not publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To get going, give us a ring on 0345 646 2711 or send us an email.
Aftercare tips
How long the results last depends on use and care. We suggest:
- Keep the area around the fresh air intake clear
- Plan the next inspection before the last report gets filed away
- Report stiff or damaged access doors
- Flag stale or damp smells in the supply air
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
Common questions in Alfriston
Do you work at weekends in Alfriston?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Just ring 0345 646 2711, or send details by email with your opening times and we will plan around them.
Is Alfriston within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Is there a report after cleaning?
Yes, both a certificate and a report with photos. It includes a recommended date for the next check.
What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
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 they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

What happens if it’s left?
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Our emergency line runs 24/7, but a planned visit to Alfriston is calmer for everyone.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, call 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

The process
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 the area around the work is covered and protected. The work itself takes one overnight shift for many single units, with bigger plant phased. Somewhere as small as Alfriston, the date and timings are agreed with you well before the day.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Let us know about parking and loading
- Have your last certificate or report to hand
- Agree a time when the area can be out of use
How to get a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare in Alfriston and across East Sussex. Work can be phased by floor, building or site to keep disruption down.
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
When to call us in Alfriston
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
These are the problems we see most often:
- Coils clogged with dust and debris
- Rooms that smell stuffy when the system runs
- Air handling units never cleaned inside
- Condensate trays that will not empty
Healthcare ventilation, from large hospitals like Chailey Heritage Marine Hospital (about 4.2 miles south-west) to small clinics, depends on clean filters, coils and ducts.
What your quote should include
- If they look at the system before pricing
- Proof of accreditation you can verify
- How they set the interval to the next visit
- Whether inaccessible sections are listed on the report
