Cooling System Comparisons
Detailed side-by-side comparisons to help you choose the right cooling solution. Compare upfront costs, running costs, climate suitability, and more.
Evaporative Cooling vs Split System Air Conditioning
Choose evaporative cooling for dry climates (WA, SA, VIC, inland NSW) where humidity is typically under 50%. Choose split system AC for humid climates (QLD, NT, coastal NSW) or if you need reliable cooling on any day.
Ducted vs Split System Air Conditioning
Choose ducted AC for whole-home cooling in larger homes (4+ bedrooms) where consistent temperature throughout is important. Choose split systems for smaller homes, targeted cooling, or when budget is a concern.
Ceiling Fans vs Air Conditioning
Ceiling fans are ideal for temperatures up to 30-32°C and provide huge energy savings. Air conditioning is necessary for extreme heat (35°C+) and high humidity. The best strategy is using both together - fans allow 2-3°C higher AC thermostat settings.
Portable vs Split System Air Conditioning
Split systems are more efficient, quieter, and better for permanent solutions. Portable ACs are suitable for renters, temporary needs, or rooms where installation is impossible. Expect portable units to cost 2-3x more to run for equivalent cooling.
Single Glazing vs Double Glazing Windows
Double glazing reduces heat transfer by 50% and is worthwhile for new builds or full renovations. For existing homes, window film or external shading often provides better value. Consider double glazing for extreme climates or if also addressing winter heating.
Window Film vs Blinds: Which Blocks More Heat?
External blinds block up to 80% of heat and are most effective. Window film blocks 30-60% of heat but is cheaper and works for renters. Internal blinds block only 20-30% of heat. For maximum impact, use external shading; for budget or rentals, use window film.
Portable Evaporative Cooler vs Portable Air Conditioner
Portable evaporative coolers are 80% cheaper to run and work brilliantly in dry climates (WA, SA, VIC). Portable AC works in any climate but costs 3-5x more to run and is noisy. Choose evaporative if humidity is typically under 50%; choose portable AC for humid climates (QLD, Sydney coast).
Ducted Evaporative Cooling vs Ducted Air Conditioning
Ducted evaporative costs 70-80% less to run and works excellently in dry climates (Perth, Adelaide, Melbourne, inland areas). Ducted AC works in all climates and offers precise control. In suitable climates, evaporative saves $400-$800/year in running costs.
Reverse Cycle AC vs Gas Heating: Which Is Cheaper?
Reverse cycle AC is now cheaper to run than gas heating in most of Australia, thanks to improved efficiency (COP 4-5) and rising gas prices. It also cools in summer. Gas may still suit very cold climates (Canberra, Hobart, alpine) for heating large spaces quickly.
Dehumidifier vs Air Conditioner: When Do You Need Each?
Air conditioning both cools AND dehumidifies - it's usually the better choice if you need cooling. Dehumidifiers are for humidity control without cooling (winter dampness, coastal homes, specific rooms like bathrooms). In humid climates, AC handles both jobs; in cool-humid conditions, a dehumidifier is more appropriate.
Insulation vs Air Conditioning: What to Invest in First
Invest in insulation first if your home has poor insulation (<R3.0). Insulation reduces cooling costs by 20-40% and makes any AC system more effective. Only prioritise AC if your current home is dangerously hot or you have no cooling at all.
Inverter vs Non-Inverter Air Conditioners: Which Should You Buy?
Choose inverter for almost every situation. Inverter ACs cost $200-500 more but use 30-50% less electricity, saving $100-250/year. The energy savings pay back the price difference within 2-4 years. Only consider non-inverter for rarely-used rooms or holiday homes.
Multi-Split vs Ducted Air Conditioning: Complete Comparison
Multi-split suits homes needing 2-4 zones with flexible control and no ceiling space. Ducted suits larger homes with 5+ rooms where aesthetics matter. For 2-3 rooms multi-split is cheaper; for 5+ rooms ducted is more practical.
