Cassette, Ducted & VRF Systems
Ceiling cassettes and ducted units are where cleaning gets skipped, because it's awkward and the office is full. We do it after hours, unit by unit, with a log your landlord will accept.
Noticing any of these?
You don't need to diagnose it — that's our job. Send a photo or a short video on LINE or WhatsApp and a technician will tell you what you're dealing with before you book.
- Hot spots and complaints at certain desks or tables
- Stained ceiling tiles around a cassette
- Grilles blowing dust or a smell when the system starts in the morning
- Rising electricity costs with the same occupancy
- No service record since the fit-out

A per-unit log with readings and photos, and a quarterly energy report — filed for your landlord, franchise or auditor.

Request a site surveyCommon questions
Can you work while we're open?+
We can, but after hours is faster and cleaner — no desks to cover and no customers under a ladder. Most clients give us a window before open or after close.
How is a commercial site priced?+
Per unit, after a free survey — a fixed price per visit in writing. Restaurants and gyms usually need quarterly; offices every 6 months.
Do you handle VRF and chillers?+
VRF systems yes, including branch boxes and controls. Small chillers and AHUs are surveyed case by case.
