AHU cleaning for kitchens and businesses in Row Green
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. If you are dealing with air handling units with blocked filters and condensate trays that won’t empty, we can put it right, from heating and cooling coils, filter sections and dampers and louvres onwards.
Work in a small place like Row Green starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Row Green buildings and their air
Food Standards Agency data includes about 5 schools, colleges and universities and about 6 care, childcare and hospital premises in and around Row Green, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. William Julien Courtauld Hospital is the nearest hospital, about 1.4 miles north of Row Green. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. We cover Row Green, about 37 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours.
Classrooms and halls at schools such as White Court School are easiest to work in when pupils are away.

What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Your own staff can handle the daily basics: 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 Row Green
Tenants, auditors and owners may want proof that the air handling plant is kept clean. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Somewhere as small as Row Green, losing a kitchen or building to a fault is felt by everyone who uses it.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Why Row Green businesses choose us
- Accredited under CHAS and SafeContractor, with ISO 9001

Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Look at the condensate drain whenever the unit is serviced
- Plan the next inspection before the last report gets filed away
- Do not store bins or materials near the intake
- Report water on the plant room floor
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Common questions in Row Green
Can a school’s ventilation in Row Green be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work.

Send us your term dates when you ring 0345 646 2711, or send details by email, and we will fit the work in.
Do you cover smaller places like Row Green?
Yes, Row Green is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.

BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.

Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare in Row Green and across Essex. Work can be phased by floor, building or site around the people who use them.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
What the work involves, part by part
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
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.
Common problems we fix in Row Green
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Row Green, that’s air they breathe for hours at a time.
Keep an eye out for any of the following:
- Air handling units never cleaned inside
- Dust built up on fan impellers
- Leaves and litter drawn into the unit
- Blocked condensate drains and slimy trays
William Julien Courtauld Hospital, about 1.4 miles north, is the nearest hospital to Row Green, and healthcare sites of every size need their supply air kept clean.

What happens on the day
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, which takes one overnight shift for many single units, with bigger plant phased. Visits to a village like Row Green are booked in advance, at a time that suits whoever runs the site.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site
- Clear loose items from the work area
Getting a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
