Air Conditioning Quote Check in Killarney Heights

Recommended. Properties with direct Middle Harbour exposure should use corrosion-resistant condenser coils. The harbour breezes carry salt that can degrade standard coils over 3–5 years.

Most homes need 12–18kW total capacity. A ducted system with 3–5 zones is the most efficient way to deliver this, typically costing $10,000–$15,000 installed.

For a typical bedroom (10–15m²), a 2.0–2.5kW split system is sufficient. Living areas (25–40m²) generally need 5.0–7.0kW. Open-plan living/kitchen areas may need 7.0–9.0kW. West-facing rooms with afternoon sun exposure should size up by 0.5–1.0kW. A proper heat load calculation is recommended.

Both are excellent. Daikin Cora is the most popular split system in Australia with strong coastal-rated options and competitive pricing. Mitsubishi Electric MSZ-AP is known for exceptionally quiet operation — ideal for bedrooms. Both offer R32 refrigerant, Wi-Fi control, and 5-year warranties.

R32 is the current standard refrigerant, replacing R410A. It has lower global warming potential (GWP 675 vs 2,088), is more energy efficient, and requires less charge. Almost all new splits from Daikin, Mitsubishi Electric, Fujitsu, and Panasonic use R32.
