Heat Pump Installation & Repair – Victoria, Australia

Why choose a heat pump in Victoria?

Victoria’s cool winters, hot summers and ambitious emissions targets make heat pumps an increasingly popular choice for both new builds and retrofits. Modern air-source and ground-source units can deliver up to 4 kW of heating or cooling for every 1 kW of electricity consumed, slashing energy bills and carbon footprints alike. Rebates through the Victorian Energy Upgrades program further improve return on investment.

Key services offered

• System design & sizing: Load calculations, zoning plans and equipment selection tailored to Victorian climate data.
• Installation: Indoor and outdoor units, ductwork, hydronic loops, smart thermostats and grid-ready controls.
• Commissioning & compliance: Testing, balancing and certification to AS/NZS 5149 and NCC Section J requirements.
• Routine maintenance: Seasonal tune-ups, refrigerant checks and filter changes to protect warranties.
• Repairs & upgrades: Compressor replacements, sensor diagnostics and integration with solar PV or battery storage.

What affects price?

Expect installed costs to range from $3,500 for a small split-system to $25,000+ for a large geothermal network. Factors include:

• Capacity (kW) and efficiency rating (COP/SCOP).
• Single vs multi-head or ducted layouts.
• Electrical upgrades (switchboard, three-phase supply).
• Site access—rooftop lifts, crane hire or heritage façades increase labour.
• Regional travel outside metro Melbourne.

Questions to ask your installer

1. Are you accredited for Victorian Energy Upgrades or Solar Victoria rebates?
2. Can you provide heat-loss calculations and expected running costs?
3. Which brands do you service in-house, and what are the warranty periods?
4. How will condensate drainage, noise and aesthetics be handled on my property?
5. What is your typical response time for emergency repairs?
