Targeted climate control for your home
Precision wall split system installations in Perth
When you need to cool an open-plan living area or heat a single bedroom, a high-efficiency wall-mounted split system offers an ideal, targeted climate solution. However, even the highest quality air conditioner underperforms if it isn't positioned, sized, and installed with expert precision to handle local weather conditions.
Our installation focus is on delivering tailored single-room and multi-head split system designs built around your home's unique layout. With over four decades of local experience across Perth, from Joondalup down to Mandurah, CrispAir ensures your system capacity is calculated accurately from the start. Every installation is completed exclusively by our qualified in-house technicians who take genuine pride in clean, reliable workmanship. Summer-proof, or your money back.

Room Comfort Guarantee
Targeted cooling engineered precisely for your chosen space.
Sizing a split system requires far more than just measuring floor space. Our qualified technicians evaluate window placement, wall construction, and airflow direction to ensure your system cools or heats efficiently without creating noisy draughts or hot spots.
We stand firmly behind our installation design with our Room Comfort promise: that room holds the temperature you set, or we fix it at our cost. If your installed system struggles during severe Perth summer conditions, our qualified technicians will return to adjust settings, recalibrate airflow, or rectify the issue at our expense.
These guarantees are in addition to your rights under the Australian Consumer Law and do not limit them.
