Flush-mounted architectural comfort
When wall space is at a premium or you want an architectural climate control solution that blends seamlessly into your ceiling, a cassette air conditioner is an outstanding choice. Delivering balanced multi-directional airflow across large open-plan living areas or commercial spaces, ceiling cassettes distribute cool or warm air evenly without taking up valuable wall real estate.
Our ceiling cassette focus covers every aspect of system management, including new architectural installations, complete unit replacements, fast diagnostic repairs, and comprehensive preventative servicing. With over four decades of local experience across Perth, from Joondalup down to Rockingham, CrispAir ensures your cassette setup is engineered for optimal airflow distribution and drainage reliability. Every installation, replacement, repair, and service is performed exclusively by our qualified technicians. Summer-proof, or your money back.

Honest service standards
Ceiling cassettes rely on four-way directional louvers and built-in condensate pumps to move conditioned air and manage condensation across wide spaces. Whether we are installing a new cassette unit, servicing an operational system, or diagnosing a fault, our qualified technicians ensure your equipment operates safely and efficiently.
At CrispAir, we uphold the Honest Diagnosis Promise: where a safe, sensible repair exists, you will always see the written repair price first, before anyone talks to you about a replacement. Always.
For new cassette installations, our Room Comfort promise guarantees that space holds the temperature you set, or we fix it at our cost. If we cannot resolve a repair issue at all, your diagnostic fee is credited directly toward a replacement system if you choose to proceed. For our Comfort Club members, every repair goes even further with a written 12-month parts and labour guarantee under our Fixed Right, Or It's Free promise, if the exact same fault returns within 12 months, so do we, free of charge.
These guarantees and promises are in addition to your rights under the Australian Consumer Law and do not limit them.
The CrispAir difference
Installing or servicing a ceiling cassette requires specialised structural knowledge, precise drainage management, and neat execution. Western Australian property owners choose CrispAir for ceiling cassette solutions because of our high technical standards:
FAQs
Yes. Ceiling cassettes are popular in modern homes with flat roofs, open-plan living areas, or room additions where wall space is limited. As long as there is adequate ceiling void depth, our qualified in-house technicians can install a flush-mounted cassette system.
While both rely on an outdoor condenser, a ceiling cassette is mounted flush inside your ceiling cavity and distributes air in four directions simultaneously, providing more uniform coverage across large rooms.
Water leaks are usually caused by a blocked internal condensate drain line, dirt accumulation in the drain tray, or a failing condensate lift pump. Our mechanics carry diagnostic equipment to clear drain lines, test pump operation, and restore proper drainage quickly.
All ceiling cassette installations, replacements, repairs, and servicing appointments are completed exclusively by CrispAir’s qualified in-house technicians, ensuring complete technical accuracy and full accountability.
We recommend having ceiling cassette systems serviced annually. Regular servicing ensures internal lift pumps operate reliably, filters remain clean, and airflow louvers operate smoothly.
