Seasonal Energy Efficiency Ratio

As of , the industry moved to a new standard called SEER2 .

Marco’s eyes lit up—the gleam of an engineer appreciating good design. “The 20 SEER? That’s a different animal. On a mild 85°F day, it’ll run at 30% power for twelve hours straight. The temperature in your house won’t fluctuate more than half a degree. The air will feel like a mountain spring—dry, cool, still. No noise. No drafts. And on that 118°F day? It’ll ramp up to full power, but even then, it’s 20% more efficient than the 14 SEER. Over a summer, you’d save about 40% compared to the builder model.” seasonal energy efficiency ratio

Note: A system is only as efficient as its installation. A high-SEER unit installed with poor ductwork or incorrect refrigerant charge will not perform at its rated efficiency. As of , the industry moved to a new standard called SEER2

Moving from a 10 SEER unit to a 16 SEER unit can reduce your cooling costs by roughly 35% to 40%. That’s a different animal
