Split System Installation Frequently Asked Questions

Split system installation costs depend on unit capacity and installation complexity. Small bedroom units (2.5kW) typically cost $1,800-2,200 fully installed, mid-sized units (3.5-5kW) for bedrooms and studies range $2,200-2,800, and larger systems (6-7kW) for living areas cost $2,800-3,800 installed. These prices include the split system unit, all installation labour, electrical connections, refrigerant charging, commissioning, and compliance certification. Additional costs may apply if switchboard upgrades are required ($400-800), if extensive cable runs exceed standard distances (more than 5 metres), or if difficult wall materials like double brick require specialised core drilling equipment. We provide detailed, transparent quotes that outline every cost component upfront, with no hidden fees or surprise charges. Our pricing reflects quality equipment, expert installation workmanship, and comprehensive warranty coverage—not the cheapest option, but exceptional value for a reliable, long-lasting cooling solution that operates efficiently throughout Perth’s demanding summers.

Split system sizing requires professional assessment considering room dimensions, ceiling height, insulation quality, window area, sun exposure, and Perth’s climate conditions. As a general guideline: bedrooms (12-20m²) typically need 2.5-3.5kW units, larger bedrooms and studies (20-30m²) require 3.5-5kW systems, living rooms (30-40m²) need 5-6kW capacity, and open-plan areas (40-60m²) require 6-8kW units. However, Landsdale’s northern location and intense summer heat often demand more capacity than basic calculations suggest. Rooms with large windows, western sun exposure, or poor insulation need oversized systems to maintain comfort. Undersized units run continuously without achieving comfortable temperatures, wearing out prematurely and frustrating occupants. Oversized units cycle on and off frequently, failing to dehumidify effectively and wasting energy. During our free site assessment, we evaluate your specific room characteristics and recommend appropriately sized systems that deliver reliable comfort without unnecessary expense. Our sizing expertise prevents costly mistakes that compromise comfort and efficiency.

Standard split system installation in a brick Landsdale home typically takes 3-5 hours from arrival to completion, including unloading equipment, mounting indoor and outdoor units, core drilling through walls, running refrigerant piping and electrical cables, making secure connections, pressure testing refrigerant lines, evacuating air from the system, charging with refrigerant, commissioning the unit, and testing all functions. More complex installations requiring switchboard upgrades, difficult wall materials, or long cable runs may extend to 6-8 hours. We complete most residential split system installations in a single visit, minimising disruption to your household. For homes requiring multiple split systems, we can often install 2-3 units in one day depending on proximity and complexity. Installation timing doesn’t vary significantly by season, though we recommend booking during autumn or spring when demand is lower and scheduling is more flexible. We arrive punctually, work efficiently, and ensure your new split system is operating perfectly before we leave your Landsdale property.

Yes—most modern split systems are reverse cycle units that both cool in summer and heat in winter, making them Perth’s most versatile climate control solution. Reverse cycle technology uses refrigeration principles to extract heat from outside air and transfer it indoors, generating 3-4 units of heat for every unit of electricity consumed. This exceptional efficiency makes split systems far more economical than traditional electric heaters, significantly reducing winter energy bills. Even when outdoor temperatures drop to 5-8°C during Perth’s coldest winter mornings, reverse cycle systems maintain effective heating performance. The same unit that keeps your Landsdale home cool during 40°C summer days provides cosy warmth throughout winter without requiring separate heating equipment. Heating mode operates identically to cooling—simply adjust your remote control to heat mode and set your desired temperature. Some budget “cooling only” split systems are available at slightly lower prices, but we strongly recommend reverse cycle units for Perth homes, providing year-round comfort and superior long-term value.

Outdoor unit placement significantly impacts split system performance, noise levels, and aesthetics. Ideal locations provide good airflow around the unit (at least 30cm clearance on all sides), protection from direct afternoon sun which reduces efficiency, secure mounting on a solid wall or ground-mounted slab, and positioning away from bedroom windows and neighbouring properties to minimise noise disturbance. We avoid locations under eaves where heat becomes trapped, near gas meters or flammable materials, or where the unit blocks pathways or creates trip hazards. Western Australian regulations require outdoor units positioned at least one metre from property boundaries unless you have written neighbour consent. During our site assessment, we evaluate your Landsdale property’s layout and recommend optimal outdoor unit positioning balancing performance, aesthetics, and compliance requirements. Refrigerant pipe length between indoor and outdoor units affects efficiency—we aim for the shortest practical run while meeting all placement criteria. Our experience ensures your outdoor unit operates efficiently, remains accessible for servicing, and doesn’t create neighbourhood disputes.

No—split system installation must be performed by licensed electricians and refrigeration mechanics under Western Australian law. Electrical connections require a licensed electrician to ensure safe circuit protection, proper cable sizing, and compliance certification. Refrigerant handling requires refrigeration licenses due to environmental regulations and the technical expertise needed to evacuate air, pressure test, and charge systems correctly. DIY installation risks electrical hazards including shock and fire, refrigerant leaks damaging the compressor and environment, voided manufacturer warranties, and installations failing building compliance inspections. Additionally, improper installation commonly causes refrigerant leaks reducing efficiency and requiring costly repairs, electrical faults potentially causing fires, condensate drainage problems leading to water damage, and units working poorly or failing prematurely. The modest savings from DIY installation are quickly consumed by problems arising from improper work. Our professional installation includes all necessary licenses, insurance coverage, compliance certification, manufacturer warranties, and workmanship guarantees—providing peace of mind that your Landsdale home’s split system is installed safely, operates efficiently, and remains protected long-term.

Filter cleaning is the most important maintenance task affecting split system efficiency and longevity. We recommend cleaning filters every 4-6 weeks during heavy use periods (Perth’s summer months), extending to every 8-12 weeks during mild weather when the system operates less frequently. Homes with pets, smokers, or in dusty Landsdale locations near construction or vacant lots require more frequent cleaning—potentially monthly during peak use. Cleaning is straightforward: switch off the unit, open the front panel, remove filters (usually simple clips), vacuum or rinse with water, allow filters to dry completely, and reinstall. Dirty filters restrict airflow forcing the system to work harder, increasing electricity consumption by 15-30%, reducing cooling capacity so rooms stay warmer, and causing ice buildup on indoor coils potentially damaging the compressor. Many modern split systems include filter indicator lights alerting you when cleaning is required. This simple five-minute task significantly extends equipment life, maintains efficient operation, and improves indoor air quality. During our installation, we demonstrate filter removal and cleaning procedures ensuring you’re confident performing this essential maintenance.

Split system installations from Big State Electrical include comprehensive warranty coverage providing complete peace of mind. Manufacturer warranties on the air conditioning equipment typically cover parts for 5 years and compressors for 5-7 years depending on the brand, protecting you against manufacturing defects and component failures. These warranties require registration within specified timeframes (usually 30 days) and evidence of annual professional servicing—we handle warranty registration and provide service reminders ensuring coverage remains valid. Our workmanship warranty covers all installation labour for 12 months from completion, ensuring any issues arising from installation are rectified at no additional cost. This includes refrigerant connections, electrical work, mounting brackets, and wall penetrations. Should warranty claims arise, we coordinate directly with manufacturers streamlining the process and minimising inconvenience to your Landsdale household. Premium brands we install (Mitsubishi, Daikin, Fujitsu) have excellent warranty support and reliable Perth service networks. We remain available for ongoing support, maintenance, and repairs long after installation—your local electrician whenever you need assistance with your split system.

Yes—split systems are excellent additions to Landsdale rental properties, increasing property appeal, commanding higher rents, and attracting quality tenants. As a landlord, you’ll need to consider whether installation is a capital improvement you’re willing to fund, or whether you’ll allow tenants to install systems at their expense (potentially with agreements for them to remove or leave systems at lease end). Tenant-funded installations require clear lease agreements outlining responsibilities for maintenance, repairs, electricity costs, and whether the system remains as a fixture or is removed upon vacating. From a property investment perspective, split systems typically return their cost through increased weekly rent ($15-30 per week premium for air-conditioned properties) within 2-4 years while reducing vacancy periods. We work with Perth property managers and landlords regularly, providing competitive pricing for multiple property installations and advice on positioning systems to suit tenant needs while protecting your asset. All installations meet compliance requirements for rental properties, with electrical safety certificates provided for landlord records.

Split system running costs depend on unit efficiency, capacity, usage patterns, and electricity rates, but modern systems are remarkably economical compared to older technology or portable air conditioners. A typical 3.5kW reverse cycle split system costs approximately $0.30-0.50 per hour to run when cooling on a hot Perth day, translating to $2-4 daily for 6-8 hours of afternoon/evening use. A 7kW living room system costs around $0.60-0.90 per hour running at full capacity. However, inverter technology in modern split systems modulates compressor speed rather than cycling on and off, reducing actual consumption by 30-40% compared to these maximum figures. Heating mode is even more economical, typically costing half as much as cooling for equivalent comfort. Factors minimising running costs include proper system sizing (avoiding oversized units), good home insulation and window coverings, setting thermostats to 24-26°C in summer rather than extremely cold temperatures, regular filter cleaning maintaining efficiency, and using timer functions to cool rooms before occupancy rather than running continuously. Your split system’s energy efficiency rating (measured in stars) indicates relative running costs—higher-star units cost more upfront but save substantially on electricity over their 10-15 year lifespan.
