When to call us in Gravesend
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:
- Drain trays holding standing water
- Air handling units never cleaned inside
- Air handling units with blocked filters
- Units needing a clean before a new tenant or handover
Wherever a school like Whitehill Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

AHU cleaning in Gravesend, done properly
Our AHU cleaning covers sites in Gravesend and the rest of Kent, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you are dealing with condensate trays that won’t empty and dirty coils holding back the airflow, we can put it right.
In a town like Gravesend, ventilation cleaning usually means offices, schools, surgeries, care homes and leisure buildings. Each has supply and extract ductwork that collects dust and debris.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

How we price AHU cleaning
The survey tells us what the work involves. The main factors are:
- A single visit or a regular plan
- Where the site is and how we reach it
- The scale of the work
- Working hours and out-of-hours timing
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before work begins.
Helping us quote
There’s no need for technical detail. Just send:
- Any access panels or hatches you can see
- Wide photos of the system and the area around it
- The times we could work without disrupting the site
- How we’d reach plant on a roof or in a plant room
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

How it 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. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and we clear up before we go. We arrive in Gravesend once you’ve closed and leave the site ready for the morning.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear loose items from the work area

Different parts, different methods
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. A few tips:
- Check the drain tray is emptying during routine visits
- Book the next check in line with the report
- File each AHU report in the maintenance log
- Report stiff or damaged access doors
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
