Part by part
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins are not damaged.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
How we handle AHU cleaning in Milton-next-Gravesend
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. Typical jobs include stale or musty smells from the ventilation and dirty coils holding back the airflow, across filter sections, supply and extract fans and internal panels.
In a smaller place like Milton-next-Gravesend, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
The paperwork matters as much as the work. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
What we’re called out for in Milton-next-Gravesend
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
Keep an eye out for any of the following:
- Blocked condensate drains and slimy trays
- Coils clogged with dust and debris
- Debris and leaves in the fresh air intake
- Rooms that smell stuffy when the system runs
If you manage shops or offices close to Gravesend station, a TR19® Air inspection shows whether the ductwork needs cleaning.
What to look for in a quote
- Whether inaccessible sections are listed on the report
- Proof of accreditation you can verify
- What’s included in the scope, part by part
- What insurance they carry
How the visit works
A visit follows the same order every time: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, clear away and leave you the report. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Evenings, weekends or a closed day all work for a site in a place like Milton-next-Gravesend.
- 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.
- We take after photos and issue the certificate and report.
Before we arrive
- Agree a time when the area can be out of use
- Move anything stored near the system
- Name a contact who can let us in at the agreed time

Why deal with it now?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. It’s easy to lose track of when the work was last done on a quieter site.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, call us on 0345 646 2711, or email photos for straight advice and a fixed quote.
