Repair or Replace? Sunshine Coast
February 24, 2025Repair or Replace? What to Do with Your Old Air Conditioning System on the Sunshine Coast
Living on the Sunshine Coast means relying on your air conditioning system to stay comfortable year-round. But if your system is getting older—especially around the 15-year mark—you might be wondering whether it’s worth repairing or if it’s time for a replacement. Here’s what you need to consider.
Coastal Conditions Take a Toll
If you live near the coast, your air conditioning system is exposed to salty air, which accelerates corrosion on crucial components like the condenser coil, fan motor, and electrical connections. Even with regular servicing, these parts naturally degrade over time, making breakdowns more likely.
Energy Efficiency and Running Costs
Newer air conditioning systems are significantly more energy-efficient than models from 15 years ago. If your system is struggling to keep up and causing your electricity bills to climb, a replacement could save you money in the long run. Modern units with inverter technology optimise energy use, providing better performance while consuming less power.

Repair Costs vs. Replacement Costs
If your unit has a minor issue—such as a capacitor or thermostat failure—repairing may be an economical option. However, if the compressor has failed, the coils are corroded, or the system uses outdated refrigerants like R22, a replacement is often the smarter choice. Constant breakdowns and ongoing repairs can add up quickly, making a new system the better investment.
Upgrading with Optional Rust Protection
