From new installations to fast repairs, CrispAir brings 40+ years of local expertise to keep your Perth home perfectly comfortable, whatever the weather.
Targeted room comfort
Wall split systems are Perth’s most popular choice for flexible, single-room or open-plan climate control. Whether you need to cool a sun-drenched master bedroom, warm an open living space, or manage climate in a home office, a split system delivers fast, targeted temperature control with whisper-quiet efficiency.
Equipped with modern inverter technology, wall split units adjust power output on the fly to maintain your set temperature without drawing excess electricity. They are quick to install, cost-effective to run, and ideal for both suburban homes and apartments across Perth.
Complete split system care
Fast diagnosis and honest fixes for electrical faults, refrigerant leaks, drainage clogs, and power issues.
Comprehensive annual maintenance, coil treatment, and safety checks to preserve efficiency and performance.
Upgrading an old, noisy unit? We safely decommission your old system and install a modern, energy-efficient model.
Expertly positioned new installations tailored to your room layout, airflow needs, and electrical requirements.
Detailed system performance checks to uncover hidden faults, test efficiency, and evaluate overall health.
Deep hygienic cleaning of filters, coils, and drain pans to eliminate dust, mould, and allergens for healthier air.
The deep pressure clean process
Over time, dust, mould spores, pet dander, and bacterial grime build up deep inside your wall unit where standard wipe-downs can’t reach. To clean it properly, we safely remove the front casing and treat the indoor coils, barrel fan, and drip tray with a specialised, non-toxic coil cleaner. We then high-pressure wash the entire assembly directly on your wall, capturing every drop of runoff in a sealed catchment bag.
When that wastewater drains out pitch-black, most Perth homeowners are genuinely amazed at what they’ve been breathing in.
