How we handle AHU cleaning in Lindfield
A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you have filters that are clogged or overdue and fan sections that haven’t been cleaned in years, we can help.
In a place like Lindfield, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How we price AHU cleaning
The diagnosis comes before the price. The main factors are:
- Travel, parking and unloading
- Whether we need access equipment or extra panels
- The condition of the system
- The scale of the work
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before work begins.
What to send for a quote
Before you ask for a quote, gather:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
- Problems your staff have spotted
- The site address and the type of premises

Lindfield buildings and their air
Food Standards Agency records list about 3 schools, colleges and universities, about 29 hospitals, care homes and childcare premises and about 3 hotels, B&Bs and guest houses registered as food businesses within about 1.5 miles of central Lindfield. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. For Lindfield, the closest hospital is Princess Royal Hospital, roughly 1.6 miles south.

At about 34 miles from central London, Lindfield sits well inside the area we cover. Visits are booked around your hours, evenings and weekends included.
Healthcare buildings such as Princess Royal Hospital, about 1.6 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Lindfield, yours matters too.

What the work involves, part by part
Internal casing and panels
We open each section through its doors and close them securely when we are done, and check every one is shut.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
What we’re called out for in Lindfield
Whatever surrounds a building in Lindfield, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
What we’re most often called out for:
- Fan sections that haven’t been cleaned in years
- Odours coming through the supply air
- Blocked condensate drains and slimy trays
- Air handling units with blocked filters
School buildings such as Lindfield Primary Academy are normally done in the holidays, so classrooms aren’t disturbed.

What else we do in Lindfield
What happens if it’s left?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Light use slows the build-up but does not stop it.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.

Advice
What AHU cleaning cannot fix
AHU cleaning can’t fix everything, and we’d rather say so up front. It doesn’t solve:
- Mechanical faults with motors, belts or bearings
- Dirty ducts beyond the unit itself
- A system that is undersized for the building
If in doubt, ring 0345 646 2711 or email us and we’ll say what we think before booking.
