California is in Climate Zone 3 - Warm-Humid/Warm-Dry (moderate heating and cooling). Homes here typically have higher cooling demands than heating.
We calculate your potential savings by comparing energy consumption at different efficiency levels:
Get professional input when making SEER decisions:
It depends on your climate and budget. In hot climates with heavy AC use, 16+ SEER often pays back. In moderate climates, 14-16 SEER usually offers the best value. Calculate the payback period for your specific situation.
Roughly 37% on cooling costs. If you spend $1,000/year on cooling, that's $370 in annual savings. A 20 SEER would save about 50% ($500/year), but the equipment costs significantly more.
For cooling, yes. For heat pumps, also look at HSPF (Heating Seasonal Performance Factor). And EER (Energy Efficiency Ratio) matters more if you mostly cool during peak afternoon heat.
Not necessarily longer, but they often have better warranties and more advanced features. Variable-speed compressors in high-SEER units may experience less wear than single-stage units that cycle on and off frequently.
