Is your air conditioner struggling to keep up with the heat?
If your unit's over 10 years old or you're spending $300+ yearly on repairs, it's time for a replacement. Here's what most homeowners get wrong: they pick the cheapest option without checking if it actually fits their space.
A 10-15 square meter room needs 9,000 BTU (2.5 kW). Go bigger than 25 square meters? You'll want 18,000 BTU minimum. And ceiling height matters too - anything over 2.7 meters means you need 10-15% more cooling power.
The best part about modern inverter units? They cut electricity costs by 30-60% compared to old non-inverter models. That's $2,400-$3,000 saved over 10 years.
Three things to check before buying:
- Energy rating (look for 4+ ticks or SEER 16+)
- R32 refrigerant (68% better for the environment)
- Professional installer with proper licensing
Don't wait for a breakdown during summer. Off-peak season replacements save you 10-20% on installation costs.
