AHU cleaning for kitchens and businesses in Southfleet
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. The work covers filter sections, heating and cooling coils and drain trays, and people most often call us about rooms that smell stuffy when the system runs and dirty coils holding back the airflow.
Work in a small place like Southfleet starts with agreeing access and timings.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What AHU cleaning can’t fix
AHU cleaning cannot fix everything, and we’d rather say so up front. It will not put right:
- Coils that are corroded or leaking and need replacing
- Faulty motors, drives or bearings
- Problems with the unit’s controls or sensors
If in doubt, ring 0345 646 2711, or email photos and we will say what we think before booking.

Why it’s worth doing now in Southfleet
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. A planned visit to Southfleet is easier to arrange than an emergency callout.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.
What you get with us
- Survey first, then a fixed quote
- CHAS and SafeContractor accredited, with ISO 9001

Between visits
After the visit, a few habits help the work last:
- Report stiff or damaged access doors
- Store the TR19 paperwork where auditors can find it
- Flag stale or damp smells in the supply air
- Keep filter changes on time and recorded
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across Kent. Larger estates can be phased building by building to keep disruption down.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.

- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
How to prepare
- Dig out any earlier paperwork for the system
- Move anything stored near the system
- Tell us the best time to work, such as after service or at a weekend
