AHU cleaning for kitchens and businesses in Riverhead
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, which is why we clean the unit itself, not just the ducts. If you have units needing a clean before a new tenant or handover and dirty coils holding back the airflow, we can put it right, from filter sections, dampers and louvres and supply and extract fans onwards.
In a place like Riverhead, 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.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

The process
Each visit runs to the same pattern: protect the area, make the system safe, carry out the AHU cleaning, tidy up and leave you the report. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. We plan the journey to Riverhead and bring what the job is likely to need.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Move anything stored near the system
- Mention any locked doors, roof access or ceiling voids
- Tell us the best time to work, such as after service or at a weekend

Related advice
What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Systems on quieter sites still build up dirt and wear, just more slowly.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.

Questions from Riverhead
Can you work in Riverhead outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in Riverhead can fit around your hours. Tell us your opening hours when you ask for a quote.
Is Riverhead within the area you cover?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Can you quote from photos?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Do you look at the system first?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
Will the ventilation be off while you clean?
Yes, while the clean is under way. We can work evenings, overnight or at weekends to keep disruption down.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
What should I send you?
Some pictures and a quick description of the system plus the address and your hours. We’ll ask for anything else we need.
How the job changes from site to site
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey so the quote reflects it.
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Common problems we fix in Riverhead
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Look out for these warning signs:
- Intake sections clogged with outdoor debris
- Dirty fans and fan housings
- Condensate trays that won’t empty
- Dirty filters cutting the airflow
Healthcare buildings such as Sevenoaks Hospital, about 1.1 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Riverhead, yours matters too.

Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Don’t ignore odours coming through the grilles
- Plan the next inspection before the last report gets filed away
- Look at the condensate drain whenever the unit is serviced
- Make sure the unit’s access doors open easily
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
Honest limits
Some problems need a different service or another trade:
- The supply and extract ducts, quoted separately
- Leaking heating or cooling coils
- Faulty motors, drives or bearings
