If your air conditioning system is aging, inefficient or constantly needing repairs, it may be time for a replacement. At Polygon BG Air & Electrical, we make the upgrade process simple — from removing your old system and recommending the best replacement, to professional installation and disposal of old equipment.
Modern air conditioning technology has advanced significantly. Today's systems are quieter, more energy-efficient, smarter and more reliable than units manufactured even 5-10 years ago. Upgrading to a new system can reduce your energy consumption by 30-50%, lower your electricity bills and provide significantly better comfort and control.
We also help eligible Melbourne homeowners access Victorian Energy Upgrades (VEU) rebates, which can substantially reduce the cost of replacing old, inefficient systems with modern, energy-efficient alternatives.
- Complete removal and responsible disposal of old systems
- Expert advice on the best replacement system for your needs
- All major brands supplied and installed

Is It Time?
Signs It's Time to Replace Your Air Conditioner
Your System Is Over 10-15 Years Old
Air conditioning systems typically last 10-15 years with proper maintenance. Beyond this age, components wear out, efficiency drops significantly and the cost of repairs often exceeds the value of the system. Modern replacements offer dramatically better efficiency and performance.
Rising Energy Bills
If your energy bills have been steadily increasing despite similar usage patterns, your air conditioner is likely losing efficiency. Older systems work harder to achieve the same result, consuming more electricity. A modern inverter system can cut your cooling and heating energy use by 30-50%.
Frequent and Expensive Repairs
When repair costs start mounting — especially on major components like compressors, fan motors or control boards — it's usually more cost-effective to invest in a new system. As a rule of thumb, if a single repair costs more than 50% of a new system, replacement is the better choice.
Your System Uses R22 Refrigerant
R22 (HCFC) refrigerant has been phased out in Australia due to its impact on the ozone layer. If your system uses R22, refrigerant costs are extremely high and availability is limited. Replacing your system with a modern unit using R32 or R410A refrigerant is the only practical long-term solution.
