ducted gas heating installation: Frequently Asked Questions
How much does ducted air conditioning cost to install in Australia?
Ducted reverse-cycle air conditioning typically costs $6,000–$15,000 installed for a standard 3–4 bedroom home, depending on the number of zones, brand, and access difficulty. Split systems cost $800–$3,500 installed per unit.
What size air conditioner do I need for my room?
A rough guide: 1kW per 10m² for standard rooms. A 20m² bedroom needs ~2–2.5kW, a 40m² open plan needs ~4–5kW. A qualified HVAC technician will perform a proper load calculation accounting for insulation, ceiling height, and sun exposure.
How often should air conditioning be serviced?
Residential split systems should be serviced annually — clean filters, check refrigerant, inspect coils and drainage. Ducted systems and commercial units need servicing every 6–12 months depending on usage. Regular servicing extends lifespan and maintains energy efficiency.
What is a reverse-cycle air conditioner?
A reverse-cycle air conditioner provides both cooling in summer and heating in winter using a heat pump. It's the most energy-efficient heating option for most Australian climates, and is 3–5x more efficient than electric resistance heaters.
How long does a split system air conditioner last?
A quality split system air conditioner lasts 10–15 years with annual servicing. Inverter models tend to outlast fixed-speed units. Brands like Daikin, Mitsubishi, and Fujitsu generally have strong reliability records in Australian conditions.
Can I install a split system myself in Australia?
No. Connecting refrigerant lines and electrical wiring requires an ARC-licensed technician and a licensed electrician. DIY installation voids the manufacturer's warranty and is illegal. Only the indoor unit mounting bracket can legally be installed by an unlicensed person.
