How we handle AHU cleaning in Great Horkesley
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from pictures or a site visit, and give you a fixed quote before any cleaning starts. The work covers filter sections, dampers and louvres and heating and cooling coils, and the jobs we see most are air handling units never cleaned inside and debris and leaves in the fresh air intake.
In a smaller place like Great Horkesley, 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.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Keeping the system healthy
After the visit, a few habits help the work last:
- Clear leaves and litter away from the intake
- Change filters on schedule and log each change
- Book the next check in line with the report
- Keep the certificate and photo report with the plant records
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Honest limits
Some problems need a different service or another trade:
- Building management system faults
- Dirty ducts beyond the unit itself
- Damaged coils beyond cleaning
If you are not sure, just phone us on 0345 646 2711 or send us an email and we will give you a straight answer.
Parts of the system we cover
- Drain trays
- Filter sections
- Supply and extract fans
- Dampers and louvres
- Internal panels

Different parts, different methods
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
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
