AHU cleaning for kitchens and businesses in Itchingfield
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. Common call-outs are for stale or musty smells from the ventilation and plant that needs cleaning after a refit, across internal panels, drain trays and filter sections.
Somewhere as small as Itchingfield, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Is Itchingfield within the area you cover?

How much does AHU cleaning cost in Itchingfield?
There’s no set price, as it 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 we start.
What if parts of the system cannot be reached?
Anything we can’t reach goes on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
How far ahead should we book?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Can you price the work without visiting?
Normally, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we usually come back within one working day. If photos are not enough, we’ll survey first.

Signs you need AHU cleaning in Itchingfield
Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
Any of these means the system needs a check-up:
- Stale or musty smells from the ventilation
- Units that have only ever had filter changes
- Debris and leaves in the fresh air intake
- Plant that needs cleaning after a refit
Healthcare buildings such as Horsham Hospital, about 3.5 miles north-east, depend on their ventilation; if you manage a surgery, clinic or care home near Itchingfield, yours matters too.
What your quote should include
- Whether the whole system is included, or only the parts that are easy to reach
- What paperwork you get at the end
- Whether the quote shows VAT
- Whether the work can be done while the site is closed
Part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey, before we quote.
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.
Fixed quotes for AHU cleaning in Itchingfield
The quote reflects the site in front of us. We take into account:
- Travel, parking and unloading
- What state the system is in
- Whether we need access equipment or extra panels
- Site requirements such as sign-in and permits
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711 or send us an email, and we will talk you through it.
Helping us quote
We can often survey from pictures. The most useful are:
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
- When the site is open and when it’s quiet
Photos are the quickest way to a quote: 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.
For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
What we do, step by step
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. If the van will struggle with a lane or gateway near Itchingfield, let us know and we will plan around it.
- 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 are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Tell us where we can park and unload
- Tell us the best time to work, such as after service or at a weekend
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
We do not publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, ring 0345 646 2711, or email photos.

Keeping the system healthy
Once we’ve finished, these simple steps help:
- Report stiff or damaged access doors
- File each AHU report in the maintenance log
- Report musty smells from the vents straight away
- Clear leaves and litter away from the intake
The report suggests a date for the next inspection or clean, 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.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
