Air handling unit cleaning in Hollow Street, Kent
AHU cleaning in Hollow Street from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Coils clogged with dust and debris
- Plant that has been serviced but not cleaned
- Air handling units due a clean after building work
How it works
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. Photos of the system and how to reach it help us plan a visit to Hollow Street.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Make sure someone can let us in and lock up afterwards
- Let us know about permits to work or site inductions
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.
Advice
AHU cleaning for kitchens and businesses in Hollow Street
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. Common call-outs are for units needing a clean before a new tenant or handover and filters that are clogged or overdue, on heating and cooling coils, drain trays and supply and extract fans.
Work in a small place like Hollow Street starts with agreeing access and timings.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What your team can do, and what needs us
If your staff spot something 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.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Do you need AHU cleaning in Hollow Street?
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Common reasons sites call us are:
- Filters that are clogged or overdue
- Air handling units never cleaned inside
- Fan sections that haven’t been cleaned in years
- Air handling units due a clean after building work
If you manage a school such as Chislet Church of England Primary School, ventilation cleaning is best booked for the holidays.
Questions to ask before booking
- What happens if part of the system can’t be accessed
- Whether the quote is based on a survey or photos
- How they set the interval to the next visit
- Whether they’re fully insured
What happens if it’s left?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. A fault that closes a site in a village like Hollow Street affects everyone who depends on it.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

How the job changes from site to site
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Between visits
After the visit, a few habits help the work last:
- Do not store bins or materials near the intake
- Make sure the unit’s access doors open easily
- Watch for drips or damp patches near the plant
- File each AHU report in the maintenance log
When we have closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
