AHU cleaning for kitchens and businesses in Ifold
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. 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. Typical jobs include debris and leaves in the fresh air intake and filters that are clogged or overdue, across supply and extract fans, heating and cooling coils and dampers and louvres.
For a building in or near Ifold, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
The paperwork matters as much as the work. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What your team can do, and what needs us
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. That part needs specialist access and equipment.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Why act early in Ifold
If people in a building in Ifold complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. It’s simpler to plan the work at Ifold now than to arrange it in a hurry later.
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.

Common problems we fix in Ifold
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Air handling units with blocked filters
- Plant that has been serviced but not cleaned
- Condensate trays that will not empty
- Units needing a clean before a new tenant or handover
For buildings in and around Ifold, TR19® Air cleaning starts with an inspection.

How the job changes from site to site
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
What affects the cost of AHU cleaning
A fixed price needs a few facts first. We look at:
- Working hours and out-of-hours timing
- Site rules, permits and inductions
- The number of sites or systems
- Whether we need access equipment or extra panels
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
Helping us quote
We can often survey from photos. Try to include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted
- The paperwork from the last visit, if you have it
- Photos showing the whole system and its surroundings
Some systems can be priced from photos; 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.

What else we do in Ifold
Ifold: your questions answered
Will you come out to Ifold?
Yes. Ifold is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Can you work in Ifold outside opening hours?
Yes, out-of-hours work is a big part of what we do. It means the site in Ifold keeps running as normal. When you call us on 0345 646 2711 or send us an email, mention when the site is quiet.
Do you look at the system first?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. The report from each visit recommends the next date.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
How much does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
How the visit works
The first job on site is protection: floors, worktops and anything near the work are covered. 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. A few photos of the system help us make the most of a visit to a place like Ifold.
- 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.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Arrange a key holder or contact on site
- Let us know how we reach the system, including roofs, risers and plant rooms
- Move anything stored near the system
Getting a quote
To get a fixed quote, ring 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. We normally come back within one working day.
