Kent · Air handling unit cleaning
Sole Street AHU cleaning
One call covers cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Sole Street, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Plant that needs cleaning after a refit
- Dirty filters cutting the airflow
- Dirty coils holding back the airflow
Leave it or put it right?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. In a place like Sole Street, ductwork and fans are easy to forget until something goes wrong.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. The price is fixed before we start.

Visits are booked around your hours, evenings and weekends included. Gravesham Community Hospital is the nearest hospital, about 4 miles north of Sole Street. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.

What AHU cleaning can’t fix
We’ll always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Problems with the unit’s controls or sensors
- The supply and extract ducts, quoted separately
- Coils that are corroded or leaking and need replacing
If you’re not sure, just ring 0345 646 2711, or email photos and we will give you a straight answer.
Where we work
- Drain trays
- Heating and cooling coils
- Supply and extract fans
- Dampers and louvres
- Internal panels
- Filter sections
What the work involves, part by part
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.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.
How it works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Sole Street, the date and timings are agreed with you well before the day.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- 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.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Agree a time when the area can be out of use
- Have your last certificate or report to hand
Getting a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.

Common problems we fix in Sole Street
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
It’s time to book a visit if you see:
- Stale or musty smells from the ventilation
- Blocked condensate drains and slimy trays
- Coils clogged with dust and debris
- Air handling units never cleaned inside
For schools like Cobham Primary School, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before you book
- What insurance they carry
- When they can work, and whether that is outside your opening hours
- Whether they recommend a next date
- Whether inaccessible sections are listed on the report
Fixed quotes for AHU cleaning in Sole Street
We quote each job individually. This is what makes a difference:
- Parking and loading at the site
- The condition we find in the survey
- Whether we need access equipment or extra panels
- Whether it’s a one-off visit or part of a schedule
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
What to send for a quote
When you contact us, it’s useful to have:
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- Wide photos of the system and the area around it
- Close-ups of filters, grilles, hatches or access panels
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 many jobs can be priced from that alone.
Between visits
Simple habits between visits make a real difference. Our advice:
- Keep the certificate and photo report with the plant records
- Report water on the plant room floor
- Clear leaves and litter away from the intake
- Check the drain tray is emptying during routine visits
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
